Subj: Hen Group Sizes
Could anyone assist with this enquiry, please?
~~~~~~~~~~~~~~~~
which is the best hen group size?
------------------------------
kag is a 27 years old farm animal protection organization cooperating
with free range farmers as licencees of our free range trade mark. our
principles of free range farming are known as the most severe ones.
actually, we are looking for practical and scientifical evidence for
maximum laying hen group size. perhaps you can give us a hint?
until lately, we have been working with maximum group size of 250 hens
(500 hens under special circumstances, i. e. voliere stable systems which
allow use of third dimension), but our experiences in practice were
rather problematical. we are convinced that groups of such size do not
respond to the animals need.
now we've decided to reduce our own principles to a maximum group size of
100 hens - it is just a first arbitrary step, a moratorium in order to
avoid further licence contracts with farmers who want to work with bigger
groups.
in a second step, we want to fix maximum group size according to
practical and scientifical evidence. two or three older studies tell us
that group size should not exceed 25, 50 or 80 hens. more recent studies
(probably written under slight economical pressure) say that group size
can be up to some thousands, if teh hens have possiblities to build
undergroups.
hopefully looking for your answers, with kind regards

I was pregnant and cared for, bathed, fed and hung out with our two African
Elephants all during my last pregnancy (my son is now 5).. They were very
curious about my stomach, partly because of its changing size but also
before that.
My impression is that the female elephant, Laura, whom I am very close to
new that I was pregnant... I think with elephants she could heara the womb
sounds. I belive this because elephants communicate through low frequency
sounds and that is what womb sounds would be...
Other than their curiousity and checking on me and the baby the rest of
their behavior was quite normal... But then elephants are matriarchal,
social animals wiht great mothering instincts and high intelligence...
After my son was born Laura seemed to already be familiar with him and no
doubt she was...He was not strange or new to her when we brought him home.
She touched his forehead with her trunk, patted him for a bit and then
sniffed all around him and then went about her business as if to say oh
its you! She is very protective of him...He also spent the first 2 months
of of his life growling...sounded just like the low rumbling the elephants
make..
Just sharing some observations...
Also have horses, dogs,parrots and others who reacted quite well during my
pregnancy. this is not to say that others might not react badly or
jealously... Our dogs are Australian Shepherds, very instinctive herding
watchful dogs, and the oldest female who is quite attached to me and
protective was also protective of my son. Not letting anyone strange near
him or his crib...

Sheree Walters

I'm sure some hardcore ethologists will be screaming
"Anthropomorphism! Burn the heretic!".... But I'm interested in
your observations, and maybe I could put an alternative slant on them.
If your elephants were accustomed to you handling them and moving
freely among them before you were pregnant, could they have noticed a
change in *your* behaviour as your pregnancy advanced? Pregnant
women generally take extra care of themselves, especially if carrying
out physical, manual tasks (like feeding elephants!). They will also
behave in such a way that makes it obvious there is something
precious and delicate inside them - putting their hands on the abdomen
and looking down at it every so often. Perhaps it was something like
this that focussed the elephants' attention on your condition?
Of course the trouble with carrying out observations that involve
your own participation is that it's not a strictly controlled
experiment. However you are contributing to an increasing batch of
anecdotal evidence about the changed behaviour of animals around
pregnant women. This question came up a while ago, centering around
dogs, and of course you also mentioned the protective behaviour of
your dogs around your son. This is an interesting topic, but I am a
little sceptical about hormonal explanations. I think it's more
likely to be based on altered patterns of human behaviour. Any other
ideas?

I know cattle can recognize more than two people, so the
answer is "more than two". To be more exact, I would suggest
"a vast number". How many people can people recognize?
If you think of all the people you have met, and could recognize,
even if you can't remember their names, I would guess that we
are capable of recognizing many thousands, if not tens of
thousands of people. In group living animals social recognition
is likely to be a highly evolved and specialized skill. Bovines are
capable of living in some pretty big groups, so an even more
precise answer is "almost as many as the number of dollars
you would have to ask for, and be refused, to do the experiment
to find out"
In any case, it is an imprecise question. What is meant by
"to recognize someone"? To know their name? To have
a relationship of some sort with them? To know that you
have seen them before somewhere?

I don't know if there are any cetacean experts on list who might be
able to explain this better....But during an exciting experience
swimming with dolphins, I learned that the dolphins can utilize their
incredible sonar skills to detect the extra heartbeat and movement of
an unborn fetus within a woman's body (not mine ;-) ).
If my rusty brain cells are working today - I think I remember the
animals' response was to be passive around a pregant woman - carefully
avoiding the usual high-energy play that they often enjoyed with other
human swimmers.

The question may be imprecise, but the implications are of interest. Often
in our domestic livestock industries we house animals together
in various size groups and pens. Are there limits to the number of
animals that can be kept together before social problems errupt due to the
animal's failure to recognize each other as part of the same group?
In Seyforth and Cheney's book, "How Monkeys see the World", they conduct
various vocal playback experiments to determine if a particular group of
vervets recognize the calls of the neighboring group. Not only can they
recognize the calls of the neighboring troop, but they seem to be able to
recognize if the calls are being played from a territory that is not owned
by the troop whose recordings they are hearing. So it appears that while
they may 'recognize' individuals outside their own social group they would
not consider every individual they recognize as a troop member. In other
words the number they 'recognize' exceeds the normal group size. Are we
exceeding normal group size in our various livestock housing arrangements?
If so do our animals pay any price for exceeding the 'normal' group size?
Somewhere in those questions emerges the role of 'recognizing individuals'
as group members or at least as nonthreatening acquaintances. It appears
that many wild species have a particular group size or family unit which
spend a large portion of their time together. During certain seasons or
under certain conditions larger aggregations of the species come together.
Can or should our cattle, swine and poultry spend the majority of their
lives in large aggregations or would they function better in smaller
groups? What evidence do we have that groups can become too large? If
the evidence exist is it related to exceeding a 'recognition limit'?
I think these are worthwhile questions and a good researcher and salesman
should be able to rustle up some money to investigate these questions.
There are numerous papers published with various species looking at the
effects of various group sizes. However, like Jon Watts is wondering, I
am not certain we have really asked or answered the questions
conclusively.
So Jeff, while we recognize you and your comments you will have to come
and spend more time with us before we pencil in your birthday on our
calendar! (The true sign you made it into our group!)

Making observations about domestic canines "protective" behaviors always
raises so many questions for me. First, how do we "know" they are being
protective of us? Maybe they are protecting themselves. Second, often we
give subtle messages to our pets about what behaviors we find acceptable,
i.e., if the breed of dog is one that has been genetically bred to "protect"
and "guard" we reinforce those behaviors both subtlety and perhaps more
overtly in situations where we want it to occur, in other words with our
children, ourselves in certain situations etc. So, is the dog "choosing" to
be protective, or is the dog responding to our desires? Does anyone wish to
comment on these questions? (I know it is a "dog" question, but feel free to
comment on other species!)

Gadzooks!! It is an imprecise question!
I'm not sure which of the more specific questions you mention would give
me an answer that really helps. Here's the situation:
Consider steers in a feedlot. If you put them in small pens with say 30
animals per pen, as in our research feedlot, you might suppose that any
animal will eventually interact with all other animals. Probably it will
be familiar with the appearance, odour etc. of all the other animals and
be able to discriminate between them and "unfamiliar" animals based on
these cues. It may well (though I don't know this) be able to associate
each animal with other information based on those interactions, such as
relative dominance, for example. At this pen size they can easily
demonstrate discrimination between a stranger or one of their own being
introduced to the pen.
Anyhow, suppose you put them instead into pens of 100 animals, or 200, or
500 or maybe even more. Do you reach a pen population at which animals
within the pen do not all know each other in this way? Maybe there are so
many animals that they don't all ever get to interact. Maybe there is
clique formation such that each animal spends most of it's time in
association with a subgroup. Maybe they do all interact, but they just
don't have the capacity to form and store useful representations of the
relevant properties of other individuals that they could use to recognise
them or know anything about them on a subsequent encounter. Perhaps their
day-to-day activities, after a settling down period, don't bring them
often into contact with animals which are unknown. Perhaps they attempt to
avoid such encounters. But when there is a source of excitement or
agitation, a storm, all being removed from the pen and turned back in, or
something of the sort perhaps some individuals are forced into contact
with strangers and thus to interact and probably fight with them while
their familiar cohort is somewhere else.
I was just wondering if something like limits on social memory might be
involved in buller steer syndrome which usually only occurs in large pens
and is often associated with events like storms or disturbances like
re-implanting. I'm not suggesting that any one factor such as this
provides a whole explanation. But the way I see it, if they can easily
recognise 500 animals then I'm completely wrong, but if they begin to
struggle with this kind of representation at upwards of 150 to 200
individuals (pen sizes where we see BSS occurring) then it might be a
factor.
I realize this doesn't completely clarify the question. But maybe it
suggests what kinds of answer might have some relevance.

I have heard this story before (i.e that in large groups animals will
not recognize each other and so there will be more aggression)
but I no longer believe it is true.
First, the same story has been claimed for people i.e. high levels
of aggression in cities. I have lived in a 3.5 million person city
and a 60 person village, and I can tell you the former was much
less stressful than the latter! People are perfectly capable of being very happy in megacities. The problems with cities do not
arise just because there are a lot of people around.
The assumption is that strangers (whether people or animals)
will inevitably fight. But is this true? When everyone else is
a friend, and you are a stranger, you may well have problems.
but if everyone is a stranger, and you have a few friends, maybe
things will be ok.
In my opinion,
the worst problems of aggression in animal groups occur when
one animal is continually harrassed by one or two others. In a
small group, this animal has little chance of escape, but in a group
of several thousand the chances of avoiding a bully are much
better. Meat poultry live in flocks of several tens or hundreds
of thousands, but I am not aware that aggression levels per
bird are particularly high.
I think that most domestic animals are capable of living in groups
that are much, much larger than what we would consider as
"natural" group sizes, as long as the conditions are right. A
more appropriate question than "are groups too big?" is the
question "what are the conditions necessary to keep animals
in large groups?".
I think the real problems with large groups are increased risk
of disease transmission and reduced possibilities for
individual care and attention from the people looking after the
animals, not increased aggression.

Hi Deb!
Perhaps it is dependent on the relationship (which supports your
expectation hypothesis). The behaviour, however, may not occur
solely because it is expected but because it is expected of the
relationship.

My experience, with many species, is:
1) Are there sufficient resources? Two animals will fight if
there is not enough of what is important to them.
2) Depends on definition of "fight". Some species have overt
aggression and others are much more subtle.
Jeff: your point re: the difficulty of caring for large groups is
important. It is difficult to scan and note health problems, etc.
when there are hundreds to thousands of animals. The only way that
system works is when you expect some to perish and it does not matter
to you (financially or otherwise).

Subj: Re:Protective behaviors
Hi Debra,
One way to address this question might be to look at the dog ethologically.
I have been re-reading "The Wolf" by L. David Mech and while it is a dated
reference, (1970), it is full of wonderful information. He describes many
instances of wolves defending both territories and individuals within their
pack. In "Coyotes, Biology Behavior and Management, edited by Mark Bekoff,
1978, there are examples of active defense of territories, especially when
there are pups present in the den (here it was frequently the females who
lead the attack on intruders). And if you go back to Scott and Fuller's
studies at the Jackson Laboratories in the 1950s with dogs, they showed
group defense behavior predictably showing up as early as (I think, I don't
have the book handy) 6 weeks of age and with a lot of similarity across
litters. I think there is a lot of evidence to suggest that guarding,
protective, defensive (whatever you want to term it) behavior is a
consistent factor in canine pack behavior and it is probably of biological
origin (and perhaps modified by learning).
It makes evolutionary sense that animals who live in groups would have
evolved a set of strategies to recognize (which goes back to Jon's question
about recognition of individuals in cattle) and protect the group. And it
makes sense to me that some of these species would have evolved the ability
to alter their protective behavior to recognize and protect the more
vulnerable members of their group preferentially.

I agree with you that generally we do not see increases in aggression with
larger group sizes in other livestock species. Both poultry and swine
seem to function with perhaps less aggression (certainly not more
aggression) in larger groups. However, the buller steer syndrome, which
may or may not be related to aggression, seems to emerge in group sizes
over 200 animals. In group sizes less than 100 it is rarely, if ever
seen. So it appears that large group sizes, at least in steers, can have
a negative effect. What you believe to be true about large group sizes in
poultry and swine does not seem to hold true for growing steers in feedlot
conditions.

I always thought that the incidence of violent crime and 'random acts of
violence' (murder, rape, shooting, armed robbery, etc.) was higher per
capita within larger cities? You seem to be saying this is not true! Or
if true, not related to larger numbers, but perhaps other circumstances
that exist in larger cities. However, that is like saying bullets do not
kill you, it is the speed of the bullet that is the problem. Perhaps the
analogy is off target :), however, I would wager you are more
likely to be the victim of a violent crime in a larger city than a village
of 60 people. If this is true, for whatever the reasons, it still means
(directly or indirectly) that larger cities have higher incidences of
violent crime.
I will try to get back on tract here! I do not know if larger numbers of
steers are more aggressive. I do not know if aggression causes buller
steers. I DO KNOW that group sizes over 200 report a greater incidence of
bullers than group sizes less than 100. This discussion did not begin by
asking if larger groups are more aggressive, though the conversation has
swung that way. The original question had to do with optimum group sizes
and if a price was paid if that optimum group was exceeded and if
recognition among individuals could be part of the development of a
problem (like buller steers). So aggression aside (and economics and
weight gain aside) - are their optimum group sizes that relate to the
ecology of the animal and is there a limit to how many other individuals
an animal can recognize as its herdmate?

Again this logic does not seem to hold true for large groups of steers.
Steers in small groups also get bullied and ridden, but in large groups
this activity attracts more and more attention until the recipient
suffers. In a small group the attention is tolerable, but in a large
group it becomes dangerous.

I have some experience working with a local feedlot operator. The owner
is very intuitive and knowledgeable about animal needs, behaviour,
handling, etc. He decided to create large "pasture-like" lots for his
steers so there was ample room and enough space so that the lot would not
develop into a feedlot environment. He tried fields of 6-10 acres and put
upwards to 500 and 600 steers into these pastures (more space per animal
then is seen in a traditional feedlot setting). When the steers sold
in early spring he planted the fields into cereal grains. It was all very
environmentally friendly and he assumed animal friendly too. However, the
incidence of bullers within his large paddocks was so high that he
abandoned the idea and has gone back to his more traditional feedlot
setting of 200 animals per pen. He still see bullers, but his overall
incidence in his 5,000 head operation is lower. The same scenario is
repeated in the literature and is being adopted in the construction of
newer feedlots. Constructing and building larger and larger pens for more
and more steers is not the norm because owners/operators know that group
sizes over 200-250 increases the incidence of bullers. You may get away
with larger group sizes in poultry and swine, but it just does not work
with steers. Why?

The feedlot industry is capable of dealing with large numbers of cattle.
They can treat disease and provide individual care to whatever number of
animals they own. If they have a 20,000 head feedlot they hire enough pen
checkers to physically observe and check each animal in each pen and treat
every animal identified as 'sick'. If they operate a 50,000 head feedlot
they hire more pen checkers. It would be to their advantage to make pen
sizes larger than 200-250 head, but the buller steer syndrome starts to
negate the advantages of larger group sizes. Larger groups of steers
create a higher incidence of bullers. Why?
I think this is one situation, Jeff, where the upper number of animals
that can be kept 'safely' together in one pen is being seen. What are
some of the underlying mechanisms here and is recognition one of them;
hence the original question.
I do enjoy your comments Jeff, I wish you were here in person to discuss
this phenomenon.
Sincerely,
Joe

Could this be a result of statistical sampling of a rare behaviour?
If 1 steer out of 200 is a buller, then you are ten times as likely to see
bulling in a group of 200 than in a group of 20 steers.
If you observe 10 groups of 200 steers, you should see an
average of one instance per group (i.e. bulling in every group).
If you observe 10 groups
of 20 steers then you will only observe bulling in one of those
groups (i.e. an average of 0.10 instance per group).
Bulling might be more commonly seen in large groups, but this
does not mean that group size affects the incidence of bulling.

I have not been following this discussion closely, but the above
statement "caught my eye." The implication from the statement seems
to be that "behaviorists" at one time believed that larger group
sizes resulted in more aggression. As one of the old timers, I was
_not_ taught (in the 1960's or 1970's) that increasing group size
resulted in more aggression. In fact I was taught just the opposite.
The argument at that time was that 1) a true social organization
could only result from individual recognition, 2) social stability
was a product of a social organization and was associated
with less overt competition for access to resources, 3) when group
size was increased beyond the capacity of group members to "recognize
and remember" others, then the group became an _aggregation_ (and no
longer a social group), and 4) within aggregations the members had
_lower_ levels of aggression because group members did not form "true"
dominance-subordinate relationships in all possible dyads!!!
(Continual mixing was argued to produce many of the same consequences
as the formation of very large groups.)
"The Hidden Dimension" (Hall, 1969) and "Personal Space" (Sommer,
1969) were two very popular books in the 1970's. Both of these books
talked about humans in crowded populations coming into contact with
large numbers of other humans on a daily basis - but forming social
relationships with only a limited number of these people. In fact as
I recall one of these books talked about lowered levels of social
response (maybe even aggression) being a consequence of large
population size - that avoiding eye contact while riding the subway
in some large cities is a method used by humans to avoid social
contact and decrease the possibility of aggression. I was taught
that these principles likely apply to groups of animals as well!
(The example in animal behavior that I have used for many years is
based on 2 weeks of observing a group of 1000 3-year-old first-calf
heifers at Douglas Lake Ranch in British Columbia in 1979. The
heifers were overwintered in one large group but then sorted and
resorted into groups of about 50 as they showed more overt signs of
calving. Among these heifers - both in the large holding group and
in the continually sorted smaller groups, there was almost no
agonistic behavior exhibited. It was my impression that these
heifers were behaving as if they were members of an aggregation and
not members of social groups. With smaller group sizes and(or) no
mixing, I believe the levels of aggression would have been more
characteristic of that found in beef heifers. One other side point -
these heifers had a much higher than expected level of
"mis-mothering" which was in part due to nutritional stress but
probably also partly due to social stress.)
It is true that in the 1960's and 1970's Calhoun was arguing that
with increasing levels of extreme crowding in groups of rats
(spanning all ages and both sexes), eventually a "behavioral sink"
will occur. One of the consequences of a behavioral sink that Calhoun
found was "abnormal" types and increased levels of aggression -
especially among groups of juvenile males. But Calhoun's
experimental conditions were different in numerous ways from the
housing systems employed for domestic animals. One of the most
obvious differences is that large group sizes in confined
agricultural animals is found almost exclusively in groups that are
young and of single sex composition. In other words, I don't think
that anyone at that time was contending that Calhoun's findings have
direct relevance to housing of domestic animals.
I believe that some of the earlier ideas about spacing and social
behavior have become "muddled" in today's discussions. Maybe to
help clarify the discussion, one question that was topical 20 years
ago is worth asking again. Is lower group levels of aggression, in
fact, beneficial from the individual animal's viewpoint? Or is it
possible that decreasing levels of aggression with increasing group
size is actually indicative of the absence of a social organization -
and thus associated with increased "social stress?"

I am no expert, but I too have been concerned about the chronic stress of
overcrowding as opposed to the more acute stressors of agonistic
encounters amongst more "naturally" spaced animals.
Amongst other things, I am an avid aquarium hobbyist. And people who keep
African lake cichlids (especially Malawian cichlids) are often told to
keep many fish in a relatively small space, in order to *decrease*
aggression problems. The theory is this: in an overcrowded tank the fish
can't set up territories, and thus won't constantly be defending those
territories. Now, this theory has always bothered me. Isn't a territory
holder in some sense less stressed/more secure than a non-territory
holder? In a fish that has evolved to hold territories, isn't the
condition of being territory-less in itself stressful?

Jeff are you taunting me? The effects of group size seem well documented.
See the review by Blackshaw, et al (1997) Appl. Anim. Behav. Sci.
54:97-108. As group size increases so does the percentage of bullers.

Subj: elephants and dogs & anthropomorphism
Someone commented to me that they thought perhaps we do not understand
even a fraction of how animals understand the world. That is why I
periodically will get brave and post a comment to your list.
I recognize that I am in a unique position, because I live with elephants,
to make observations. I try to leave it up to you all who have studied
ethology to interpret what I have observed. Sometimes, however I think
that some of "you" and also some of the biologists and others, particularly
those who observe from a distance can they miss a lot by being either too
structured (not allowing enough anthropomorphism or even intuition to creep
in). I also think that sometimes the reasons why an animal does something
may be attributed to a reason that makes no sense to someone who is
accepted into the animals group...because we see it from a different angle
because of our proximity and daily interaction. I acknowledge that our
interaction can also, at times, change the way the animal responds..to us
and to the whatever situation it is presented with...
Just some thoughts...I enjoy and learn from all of your comments, thank you.
Someone on one of these lists once reminded me that electricity would not
have been discovered if it were not for wonder and curiosity. I think also
through playful discovery! It was certainly not all through formulas and
structered elimination processes and diagnostics and whatever scientists
use to proove something...(the name of the guidelines, and the theory, for
proving something escapes me at the moment, help? I know I have heard it
mentioned here...)
I hope that we all can better understand these amazing creatures better
one day..
Also - I realize that this is not the bioaccooustics list and so except for
one comment about the whales and dolphins, my comments about infrasounds
were not addressed to much. I really felt that the elephants were aware of
my pregnancy more because of their ability to hear low frequency sounds
than hormonal changes in me...
It is also of interest to note that I was giving elephant baths, scrub
brush in hand - without hesitation until I was about 8 months
pregnant...then I finally said enough is enough...So I did not change my
behavior as much as some women might have. I was healthy and in good shape
so continued the strenuous work of hauling hay, wheelbarrows, bathing,
shoveling manure (each shovelfull weighs 43 pounds)etc... Not bragging just
sharing... I am sure I must have done them all in a different fashion
though because of the weight distribution (not to mention the morning
sickness the first 3 months which slowed my shoveling technique
tremendously ie: shovel, run for the door, shovel, ha ha...a little levity
here for the women in the audience...who have been through that awful part
of pregnancy..)

Australian Shepherd protecting the baby in the crib - I never asked it too,
in fact was trying to show the baby to someone (who was a stranger to the
dog) and the dog would not let them in the room. Now granted I don't
usually take strangers into that room or if they are they are ususally
women friends of mine. This instance involved a man who was a friend of the
families who did visit often. My dogs generally though do not care who goes
in what room once I have let them know it is okay for the person to be in
the house to begin with. I never thought it had to do with hormones.

I have also seen my Aussie get very upset when someone other than me tries
to ride my horse. I find this very annoying... and have never stopped
anyone from going near my horse much less getting on it. Since at that
point that they would have been invited to ride by me.. Perhaps the dog was
just reacting to change? More than protecting my horse? Or the baby?
The dogs are also more protective of me than anyone else in the family (now
that my son is 5) Does this have something to do with them perhaps thinking
I am the alpha female?
Also my reasons for talking about herding type dogs was basically to point
out that they seem to react differently to new births or changes in human
family structure than other non-herding dogs where it would appear their is
a problem with jealousy...
Perhaps though this has less to do with breed than the way humans each
relate to their dogs..
At our house we practice teaching our dogs when to "back off" and give us
space. Much the way a mother dog would as was commented on on your list a
few months back.... when the topic was separation anxiety etc..

I was just wondering if something like limits on social memory might be
involved in buller steer syndrome which usually only occurs in large pens>>>
But if buller syndrome was associated with difficulties in social
memory shouldn't you find it also in small groups that are
composed of strangers, or when animals are reintroduced
into groups after a lengthy absence? This is the case with
aggressive behaviour. If you merge two small groups into a large
one, does the bulling tend to occur most between animals that
were not orginally in the same group?
Another possibility: perhaps bulling requires the combination
of particular types of individuals and you are more likely
to find these particular types together in a large herd than a
small one (?)

Subj: question
I have been avidly following the cattle memory discussion and some
terms keep appearing that I would like to question. For example,
"bullying", "aggression", etc. in reference to what appears to be
dominance behaviour. These are qualitative terms which do not appear
to sufficiently describe the behaviour AND adds some subjective
negativity.
This is connected to an incident this past weekend where I
worked with a sow that had been described to me as "crazy",
"aggressive" and had "attacked" a few caretakers. It quickly became
apparent that the sow was protecting her litter (piglets were being
taken from a neighbouring sow).

Dear Jeff, Joe, Ray and others,
I've enjoyed the exchange of opinions on group sizes, buller steer
syndrome, aggression and so forth. Please Jeff and Joe, do continue
taunting each other, it's fun to read!
My original (imprecise;-) question was about how many herdmates cattle
can recognise. I'd still like to get some views on that, if there are
any.
Regards
Jon
P.S Any interpretation of what is meant by "recognise" will do for now!

I don't know about the hormones & pregnancy connection, but I know of a lot of
anecdotal info indicating that animals can identify menstruating women (I'm
guessing this is not "hormonal", but I'd guess the same for pregnancy) and
change their behavior in response (usually increased aggressiveness by males,
often directed toward the woman). I always thought this was pretty
interesting, but don't know that anyone's ever looked into it formally.

Subj: RE: Cattle social memory; i.e., large groups, and aggression
I find the large group vs aggression question an interesting one. I think the
data do indicate that large groups show decreased aggression due to decreased
social interactions, but that overcrowding causes increased aggression, and
overcrowding seems to be a matter of perception. I think Joe is right that the
incidence of violent crime is higher in larger cities than smaller ones in
Western society. However, I bet the incidence of violent crimes in large
Japanese cities is less than that in smaller US cities. I also suspect this
has something to do with Japanese cultural coping mechanisms, like the tendency
to avoid eye contact that Ray mentioned. It's when the prevalent coping
mechanisms fail that we see the problems. (And so, back to how many cattle can
a given cow recognize....?)

I always figured that it had something to do with the smell of blood.
My dogs were always interested in that portion of my anatomy that had the
blood scent on it.
I found it embarrassing when I was in my teens, but now the point is moot.

I worked at a children's petting zoo when I was in school. At the

some of the facts you've outlined in the past about Attention Deficit

A couple of thoughts --
"Grouchiness" is a tool that can be elicited or reinforced. Probably a
back up system when negotiation fails. Part of the frustration-aggressio=
n
model wherein failure of reinforcement elicits a temporary escalation of
previously effective instrumental responses -- might be learned or
instinctive responses. In other words, kicking a stuck door often works.=
Exhaustion and depression and fear and bunches of antecedents -- Bruce
Pennington suggested in an offhand manner that Executive Functions are th=

most newly evolved and we might expect them to have less robust
foundations. They depend (probably) on the stability of a wider network =
of
underlying systems than perhaps some of our other, more automatic or
instinctive routines. We can expect EFs then to shift their bias in
reaction to a very very wide array of events.
Erosion in EFs then is correlated with relative gain in more instinctive
systems such as grouchiness, spite, self indulgence, and many lizard
routines. (can't wait to hear objections to "lizard" since we share a
common ancestor but not a lineal tie with them. just means the common
routines were possibly shared by our common ancestor and we learn about
that ancestor by the things we share w lizards. better stop, I'm getting
weird!)
Also, caught your reference to Kauffman's models in response to Sally G. =

had similar thoughts about her model. I think I've found an array of

I am an undergraduate student at UMCP majoring in Marine Biology (with a
specific interest in marine mammals, so I enjoyed the earlier message
regarding the speculation about dolphins being able to detect pregnant
humans and behave accordingly).
I also have dogs (and cats) and would offer my own speculation (not based
in research, mind you) that dogs are protective because of their wolf
pack heritage and their role in the pack. I don't think it is hormonal
or even bred for (although the trait could certainly be intensified by
breeding). From what I know about wolves and the alpha/omega thing, all
of the wolves will protect the alpha. In the case of domestic dogs,
since the owner is the alpha and the owner's children are the alpha's
children, it makes sense to me that a dog would sense it's role to protect.
I would agree, though, that protective behavior stems from different
origins depending upon the species (i.e., the dolphin example).

1) I am also interested in the answer to this.
2) Also, here in Montreal, they market "grain fed chicken" and sell it
for more than regular chicken. What the heck do ordinary chickens eat??
Is "grain fed" supposed to mean something else, i.e. that the chickens
are raise differently than regular chicken.
3) Thirdly, is there a way of distinguishing between poultry raised for
poultry (broilers, I beleive?) and those laying hens (layers?) that are
too old to produce eggs, so they are sold as chicken? (I bought an
"economy pack" of chicken legs, one time, and almost all of the little
legs were broken around the ankle...I have trouble dealing with
that...).
Thank-you,

It is my opinion that the purpose of most of these virus hoaxes is to get
people to send them to each other and to lists, so that then other people
can tell them they are hoaxes. One list that I was on spent two full days
with dozens of posts just discussing how annoying these virus hoaxes are.
And here I am doing the same thing..........
Actually I have a wonderful virus warning that is really clever.
Anybody think I should send it to this list???

Subj: WARNING-EMAIL VIRUS-READ THIS MESSAGE
I have just received a message from the FBI about a particularly
deadly computer virus. Apparently, this virus will attack anyone
who sends a message to a email list, warning of a virus sent
by email! The virus can destroy software, hard drives and even
melt entire PCs! (Ever wonder why you haven't seen a warning
about GOOD TIMES lately? It is because the people who sent
the warnings, all have had their computers destroyed by this
virus!).
Therefore, please, for your own sake, under no circumstances
must you send a message to applied-ethology warning of a
virus sent by email! Or even send in a comment or a complaint
or an explanation or a refutation of such a message.
Don't even think about it. That may be all it takes, to be struck down. YOUR FATE IS IN YOUR
OWN HANDS!! BE WARNED!!

It is my opinion that the purpose of most of these virus hoaxes is to get
people to send them to each other and to lists, so that then other people
can tell them they are hoaxes. One list that I was on spent two full days
with dozens of posts just discussing how annoying these virus hoaxes are.
And here I am doing the same thing..........
Actually I have a wonderful virus warning that is really clever.
Anybody think I should send it to this list???

I hate to break to you, but this is one of the oldest hoaxes there is. I've
seen variants on this warning come through on other listservs, one involving
some kind of fruit that was supposed to kill the people who ate it and one
having to do with something called the "Midas Touch." Here are a few tipoffs
that this is a hoax:
1) This "Forward this message to everyone you know" crap. If it were really
meant as a warning about the Greek army, why tell anyone to post it to the
Phonecians, Sumerians, and Cretans?
2) Use of exclamation points. Always a giveaway.
3) It's signed "from Poseidon." Granted he's had his problems with Odysseus
but he's one of their guys, isn't he? Besides, the lack of a real header with
a detailed address makes me suspicious.
4) Technically speaking, there is no way for a horse to overwrite your entire
city. A horse is just an animal, after all.
Next time you get a message like this, just delete it. I appreciate your
concern, but once you've been around the block a couple times you'll realize
how annoying this kind of stuff is.

If I can give a modest input on this one, I would say the point is missed on
the "Trojan horse warning" sent by Emily Patterson.
This is not a hoax, this isn't even meant to be a warning, but a simple
joke. The way I see it, whoever wrote this was aiming for a sarcastic
analogy with a computer virus warning, using an episode from ancient
Greece's history, described by the poet Homerus.
In that episode, a Greek girl named Helena was abducted by the son of the
Trojan king, Pais. So the Greek went to battle and wanted to raid Troje.
Only one problem, it lasted 10 years and they still weren't inside the city
walls. This is where they come up with the idea to use a ruse by building a
huge wooden horse and by stuffing it with Greek soldiers. After having put
the horse at the city gate, the Greek left. Of course, the Trojans, having
thought the war was over, dragged the 'gift' within their city and at night,
the Greek in armour came out of the horse and conquered Troje.
So, I would like to extend my thanks to Emily Patterson for sharing this bit
of humour with us!
Sincerely,
Christel Moons

Subj: New life form discovered
I think we are missing the important point about email virus
hoaxes: they are a totally new life form.
Anyone who as followed Richard Dawkins and Susan Blakemore's
views on memes will recognize email virus hoaxes as a
perfect example viz.
1. they survive and replicate purely because they survive
and replicate not because they serve any "function"
2. their survival and replication depends totally on their
ability to influence the human central nervous system through the transmission of abstract information
However, their capacity to elicit lengthy discourses on Homer etc.
is probably only a biproduct resulting from the disturbed
functioning of the infected brain :-) (Or is this a mutant
of the original meme?)

This isn't funny Lor! I used to spring from the bath like

I would like to borrow the reply addresses to ask an

It is another slew of jigsaw pieces. Like I always say

The Pieces
1. The (human) brain normally reacts most strongly to

2. Certain sounds seem by common consent to be

ominous cracking of support or branch about to

3. Last night I watched an very "hammy" Australian

By now you will have the picture into which I would=20

4. Here is another piece! John Fentress drew our
attention to "music and epilepsy". Now if you
can arouse the brain in certain ways you can
ameliorate seizure activity. Mozart's Sonata
for Two Pianos (K.448) is cited as reducing
brain seizures. Weinberger does not know=20
what feature of the music might be effective.
My huge guess is that pizzicato passages
of piano might be attaining around 40 plinks

the CD? Could someone dash to the piano
and knock it out for me?
Help here! I am fit to froth with frustration.
Of course the Elgar School of Music is just down the
road but I would like some formed material from
the evolutionary guys first. So please. Up into=20

In the name of research of course.

Pierre,
I assume you are asking this in the context of operations done
on animals, such as tail docking, dehorning etc.
The Oxford English Dictionary defines mutilate as
"injure or damage a person or animal or part of the body very severely, e.g. by removal of a limb or organ". In my opinion,
when the word is used in relation to people it has
a definite negative connotation either implying an accident
or a deliberate attempt to do harm (e.g. "He was mutilated in the
accident". or "Mutilated bodies are often found after a cruise missile attack".)
I do not think many people would say that
"I was mutilated by the surgeon" if I had had a leg amputated
for medical reasons. If they did, it would suggest that the
surgeon had done a bad job. Referring to operations done
on animals, such as dehorning, as "mutilations"
gives them a negative connotation. If you want to be neutral,
or want to give the impression of being neutral, or don't want
to prejudge the issue by the choice of words,
"amputation" might be a better word.

Hi Robin & Jim,
You may be interested in my 1996 paper in the Journal of Experimental
Psychology on changes in subjective time in response to click trains - I don't
have any reprints left I'm afraid. Basically, time subjectively slows down in
response to clicking noises (which are thought to increase arousal), giving you
more time to get out of the way. Fits in nicely with your idea. I always
thought this was an adaptive response, but hadn't made your leap to reptiles &
rattlers! We didn't find a sex difference, and assumed other 'arousing' stimuli
would have a similar effect - some work by Treisman used white noise to similar
effect. The paper isn't written from an ev. psych. perspective. Feel free to
forward this to anyone who may find it interesting.
Here's the ref. & abstract:
Penton-Voak, I.S., Edwards, H., Percival, A., Wearden, J.H. (1996).
Speeding Up an Internal Clock in Humans? Effects of Click Trains on
Subjective Duration. JEP: ABP, 22, 3, 307-320.
Abstract:
Four experiments investigated the effect of trains of clicks (usually 5 s long
and at 5 or 25 Hz) on subjective duration in humans, as previous research had
suggested that such a manipulation would speed up the pacemaker of an internal
clock by increasing participants' arousal. The four experiments used temporal
generalization, pair comparison of duration, verbal estimation, and production
of short durations. In all cases, preceding the durations to be judged by
clicks changed their subjective length in a manner broadly consistent with the
idea that pacemaker speed was increased, by an average of about 10%.

Ian

Subj: RE: Housing Chickens
Hi Rob!!!
I don't know if you remember me, but I worked with you on Marak's
pig project out in the barn a few summers ago.
I am going to pass some info to you - some is opinion, some is
from literature and some from my research. I did a study on egg
quality in cage vs floor housing systems and have experience caring
for birds on the floor and in battery cages. I have also done some
projects on nutritional pathology in caged layers and some of that
work includes delving into the physiological consequences of standing
on slanted wire floors without exercise or ability to move your body.
> 1. What types of environmental enrichment are available for chickens in battery cages?
I don't know what commercial items are available. I think
environmental enrichment needs depend on the environment. For
example, we have a few rooms of hens in battery cages but these rooms
have people going in and out during the day. The birds appear much
calmer than some battery caged birds and seem to attend to people's
presence.
I have used shiny, coloured paper that the birds love to shred.
I would put it behind the battery cage (on the outside) and secured
with metal. I suspect even cardborad with printing or coloured dots
would suffice. My experience has been, if you put the paper or
cardboard IN the cage, it quickly gets ripped to shreds.
> 2. Do chickens ever use the pecking toys that are often placed in the cages, or are the toys really there for the benefit of concerned humans? If they do use the toys, does it have any noticeable e
> fect on the health or productivity of the birds?
A way to look at this is to ask "Is a bird without occupation a
stressed bird?" We all know the negative impact on health and
productivity (on any species) of chronic stress.
> 5. Are battery cages really as bad for chickens as they would appear to be from a human point of view? (I sure wouldn't want to be confined to a battery cage, but do the chickens mind it that much?
Differences I have found in floor housed chickens vs battery
caged chickens:
i) Battery caged chickens have more vocalizations that are
interpreted as alarm calls, distress, etc. than floor housed
chickens. This is increased in chickens moved from the floor to a
cage.
ii) Battery caged chickens do not appear to be aware that they are
laying eggs vs floor-housed hens who have elaborate routines before
laying.
iii) Battery caged hens develop feet and leg problems from lack of
movement and standing on slanted, wire floors.
iv) Battery caged hens, despite adequate nutrition, cannot maintain
bone strength and density because of the lack of opportunity to
exercise. One reearcher here at the University of Guelph designed a
battery cage that is larger than code but with perches. A simple
opportunity like stepping up and down from a perch helps maintain
bone health (step aerobics!!!) (The birds' behaviour appeared to be
calmer with no distress vocalizations and less aggressive behaviours
to humans and conspecifics despite 15 hour full light schedules).
Because of poor bone density, caged birds probably suffer more
when sent for processing. Removal from the cage often results in
many broken bones and the struggle during hanging before stunning at
the processors causes more damage.
v) Caged birds are more aggressive to humans and conspecifics.
vi) Cage birds
>
> 6. If a chicken escapes from a battery cage will it voluntarily return to the cage to sleep, eat, lay eggs, etc.? In other words, does the chicken think of the cage as home?
Birds are territorial and I suspect a cage becomes a territory.
In my study, where we changed birds between floor conditions and cage
conditions, the birds struggled fiercely and vocalized distress calls
when we tried to put them in cages.
Birds removed from cages and put on the floor did extensive
stretching and wing-flapping (about 2 hours).
>
> I don't know much about chickens, and anytime I ask about housing I often get a very emotional response, either for or against the cages. I appreciate any information.
>
I wonder if the emotive reaction of humans is in response to the
behaviour of the chickens and the distress vocalizations?
OR
I wonder if humans who sit in front of a computer for 8 hours a
day without moving and develop back and wrist problems are just
empathizing?

Subj: RE: Housing Chickens
Hi Deborah,
Many thanks for your message and information re. housing laying hens.
I am currently writing a paper in which one of the issues I am trying
to address is the latest work on welfare in cages and welfare in
free-range systems, so a couple of your points really caught my
attention.
It appears you have done some work on the effects of sloping
cage floors. Could you please tell me where this is published, or
supply details such as slope of floor, stocking density, group size,
calcium levels, etc.
Also your comment that caged birds are more aggressive than
non-caged birds is rather different from my own experience. How
did you measure aggression?
Many thanks,
Chris

Well, in Europe if you want to label eggs as 'free range' (or
three other alternatives: semi-intensive, deep litter or
perchery/barn) there are legal specifications. But I'm sure that in
some other countries there are no legal limits on use of such terms.
I was amused last time I was in Canada to hear that someone was
marketing 'Range Free Eggs' which could, of course, mean either of
two quite different possibilities.

Ordinary chickens eat mash. Presumably 'grain fed' ought to mean
that they are fed at least some of their diet as whole grain, but you
would have to check your local laws on that.

Spent laying hens are rarely sold as chicken meat, because they have
very little meat on them and what there is is tough - they may go for
soup or pet food or often they just go into landfills. (Although as
it happens I've just come back from Zimbabwe, and they are sold
(live) for consumption there). So I am sure that what you bought
were broiler legs. I suppose they were economy precisely because
they were broken (although it wouldn't be the 'ankles': the breaks
would presumably be above the hock joint, the equivalent of our
knee). I wouldn't know, though, whether the breaks were more likely
before death, or after.

I have not done studies on the effects of sloping cage floors.
However, I work and have worked with birds (layers) housed on the
floor and in battery cages. This experience is the source of my
anecdotal observations but there is also research available.
I can get you the references but not until later next week. I am
just finishing my master's and meeting some deadlines so time is at
a premium. Computer searches would give you access to this material
but you must look in the nutrition/welfare/housing areas. For
example, nutrition is involved because diets are designed to
compensate for the metabolic demand of egg laying. However, bone
density and overall bone health is difficult to maintain without
exercise (especially weight bearing exercise) even with the best diet
formulation.
Some research on the effect of sloping wire cage floors on feet
and legs is rather dated but still applicable.
Welfare is an issue for housing, health and, later,
transportation because these birds are not fit to travel.
> Also your comment that caged birds are more aggressive than

> did you measure aggression?
Please describe your experience.
Again, my comments are anecdotal and experiential and resulted
from research I did measuring egg quality in a cage vs floor system
(I also work with cage and floor housed birds). For example, floor
housed birds I have worked with have less fear of humans, approach
humans and greet humans with a "coo coo" call. Caged birds screech,
bang around and hit the cage sides with feet and wings. Most caged
birds peck and bite human caretaker fingers but this behaviour may
occur in 1 of 25 floor housed birds.
Trimming toe nails and beaks of floor housed birds is a "piece of
cake" . The same work on caged birds is stressful for all concerned
and the escape behaviours of the birds in cages could result in
damage to themselves and their caretaker. Try it.

Dear Deborah,
Many thanks for taking the time to reply.
It appears this was a case of mistaken identity. I envisaged from the
tone of your original comments that these were statements of scientific
fact which had been subject to scientific peer review. Because of the
wide range of backgrounds on this bulletin board, perhaps we should all
attempt to develop a system whereby we let the reader know whether
statements are opinion, based on experience, or published findings
developed from rigorous experimental technique.
By the way, I think many people would believe your description of
'aggression' behaviour in poultry is more similar to 'fearfulness'
Best wishes,
Chris

Subj: Fish - killing/death
Dear colleagues,
Your advice on the enquiry below would be greatly appreciated.
With Kind Regards,
Janice Cox
~~~~~~~
HOW DOES A FISH DIE?
dear collegues
I am working for a swiss farm animal protection organization
(kag, st. gallen). I also run some private animal protection projects. one
of these projects has as its goal a label for fish produced in a
way most respectful towards the animals and the natural
ressources.
we decided to start with fish from swiss lakes (in switzerland,
at about 300 families still live from fishing, with an average
catch per day of let's say 20-30 kg).
our provisional label rules say that fish has to be killed
individually as soon as the net is taken off the water. we think
that this will prove to be - besides better freshness and
greater sustainability - a strong argument for swiss fishers
who suffer under importation of much cheaper (sea) fish.
but only few fishers are ready to sign such a prescription
(even if weekend by some exceptions, like big catches or stormy
weather). most of the fishers say that killing fish right after
taking them out of the net is either impossible in most of the
cases - or not necessary at all, because fish die quite
differently than farm animals (i. e. they suppose it to be
normal for a fish to get swallowed lively or the starve beacuase
of lack of water - and thus they assume it to be "natural" that
a fish starves conciously once taken off the water).
Advice welcome - I am not asking you to know your personal opinion (we will
ask
for that by means of a consumer^s opinion poll) - I am looking
round for biological and ethological well based answers to the
question: WHAT IS THE NATURAL WAY A FISH DIES - AND WHAT DOES
THIS MEAN FOR THE SETTING UP OF LABEL RULES?
thank you very much for all hints,
sincerely

My statements are usually prefaced with "in my opinion" and "my
experience". Most scientific "facts" often result from investigation
into anecdotal evidence. I have found that most people who express
their opinions on this listserv are very good at identifying it as an
opinion, experience, etc..
> By the way, I think many people would believe your description of

The term "aggressive behaviour" describes the behaviour and not
the motivation. As you know, extensive study would have to be done
to determine the motivation of the behaviour.
