I do get relevant stuff passed on however, and I feel I have to reply to the current debate about feeding patterns in bovines. 1. I must first correct the representation of IGER's preference work made by Tony Brereton. We did not find that animals eat more clover in the evening. They eat more clover in the morning, then include more grass in the diet in the evening. 2. Clarity would be gained by making a distinction between mechanism and purpose. The spectral sensitivity hypothesis is of sufficient merit to proceed to experimental test but it must be recognised that it is only a mechanism - there is no advantage in fitness per se from doing this. 3. Looking firstly then at mechanism - can this really explain all the meal patterns? I think not. It may explain how the animal manages to time the start of its evening meal with no other obvious cues. However, it is not the only explanation. The USDA work mentioned by Joe Stookey in earlier discussion shows that animals can distinguish between hays cut at different times of day - i.e they appear to be able to detect the change in sugar content. If this holds for fresh forages then they don't need a cue to start grazing from light quality - it is there in the feed. Even if light is involved - does the animal need a cue to start grazing? Maybe all that is needed is the sunset light intensity cue to shut down the evening meal and the rest of the pattern is entrained. None of this explains the pattern earlier in the day or the shift to some night grazing as photoperiod reduces. The animal starts the day relatively empty but does not attempt to 'fill up' at 'breakfast' (do we really need these anthropomorphisms?) - why? If the animal is trying to maximise its daylight grazing time why doesn't it just get on with it at that point? Possibly because it's foraging optimally by waiting to eat more-digestible material in the evening? Another possible mechanism we have speculated about is the difficulty of prehension of herbage in the morning while wet with dew. We know that bite mass and intake rate are much higher in the evening. This suggests some physical constraint may be operating. (Yes I know the grass is always wet in Ireland!) None of the discussion has mentioned ruminating - I don't think we can understand the meal patterns without considering this. 4. So what about purpose? We have considered these possibilities: a) The animals are foraging optimally by eating more-digestible material in the evening (more water soluble carbohydrate in grass; more starch in white clover). b) They don't want to graze at night as an anti-predator strategy. Therefore they fill up in the evening so as to be able to maintain the rumen flora during the long enforced overnight fast. This also offers a reason for switching preference to grass in the evening - it is more slowly digested and hence has a longer residence time and thus maintains rumen flora. 5. Tony Brereton mentioned that his original brief was to increase intake in rotational grazing. We have carried out a trial in which we offered dairy cows in a daily strip grazing system their new allocation of herbage either in the morning or the afternoon. Those offered new herbage in the afternoon consumed most of their daily intake in the evening (16 out of 18 kg DM) while those offered new herbage in the morning ate only 12 kg immediately and still waited until evening to eat the remaining 6 kg. The daily DM intake was the same for both groups. However, by the end of the 10-week trial the 'evening' animals had 5% higher milk yields suggesting that they were able to obtain a better diet by eating in this way. 6. Finally let me be honest - most of this is speculation, we need to stop talking and start designing the experiments to test these hypotheses. Dr Andrew J.

How do you feel now about the possiblity of increasing pasture intake of cows from either of the two methods you describe? Do you think there's a possiblity from the behavioural perspective - which often revolves around making pasture more palatable? I'm sure many nutrionists in NZ (if there's any left) would argue that it's possible to suppress intake (below some "normal" level) by offering too little pasture of the appropriate architecture, or by offering unpalatble pasture, but that it'd be difficult to greatly incr intake. BTW, I'm a behaviourist, and am fascinated by your topic. ============================================== Dear Lindsay The pasture work (in co-operation with Queen's Univ., Belfast. Imelda Casey post-grad) has not yielded any surprises or suggested easy options for increased intake.The work concentrated on sward structure effects during the bout (instantaneous rather then daily intake). Herbage density and sward height are both important. A tall sward allows a deeper bite, a dense sward yields a heavier bite. But, as you know, height and density are inversely related. That work has moved on to investigate the dynamics of leaf and tiller growth to identify the controls of the relationship between height and density.(some of this is in "Pasture Ecology & Animal Intake 1998. ISBN 1 901138 23 2). The animal behaviour work suggests that total daily intake is controlled by the animal. In my original message I suggested that 3 controls operate. One of these may be related to a daily demand that is set by the size and productivity of the animal. If that is the case then manipulation of sward structure or the other controls (light quality, bout feeding) that all affect instantaneous intake rate, may be irrelevant. In summary, it seems to me that if you want greater intake rates then buy a bigger animal (which, I think, is the current trend). Total annual herbage intake is another matter - if we could extend the herbage growing season. Anthony Dr. A. J.

Dear John and all, I would like to reply to Jon's last message asking (among other things): "Are animal minds really like the insides of black holes, that can never be properly observed from outside? Or do we just have to think real hard about how to do it? Or maybe spend enormous amounts of money and human effort, to explore this inner space?" I have some theories and suggestions on this.... I do not find it easy to get inside the minds of some of the animals of average intelligence like say a dog, a horse a bird, a rat... I know how to work with these types of animals with various methods, clicker training, positive reinforcement, etc.. I tend to know what they are up to. I also see my daughter show her horse and anticipate him and encourage him to perform for her. But they are all operating on a level different from ours as you know...But then there are the elephants.... There are 2 African elephants living with us on our farm and I have been with the female for 10 years. I am still amazed at how intelligent they are. People ask me if they are our pets and I answer that they live with us. Technically we own them but I consider them more like my children related to intelligence. I would not say I owned my child. I am not going to get anthropmorphic on you at this point.. I say they are like children becuse they are at a level intelligence-wise of say an 8 to 10 year old. I think that people who are working with dolphins and whales and apes choose them because they are so smart...It seems to me easier to get "inside" the mind of a more intelligent species. I suggest that more studies should be done connected with elephants to answer come of the questions you have raised. They use there trunks like and arm and a hand. They have similar social structure to humans. I could go on....my point is that since they have similarities already to us that we can relate to perhaps the primates, they would be a good species to work with. Part of the problem with studying elephants is that in the wild they do not let you that close, nor do they generally accept a human as part of their herd so the interaction is not as available. It is more observation. At a most zoos the type of observing that is done or allowed is mostly hands off with little or know interaction between the elephants and the public (for safety reasons , I realize) so the commen perception is that they are this big dumb, mute creature...very far from the truth... There are articles coming out now that suggest perhaps they mioght be sentient beings. There are also updated and new books that place elephants among the top four species regarding intelligence after humans,,,, certain primates, then dolphins, whales and elephants. It would appear know one yet knows which order for the last 3. For many years people thought (and some still do) that African Elephants were not trainable or easily handled. First, many African people hold elephants in high regard and out of respect for their power and place on the earth (plsu there size), somewhat similar to the tpe of reverrance held for certain animals in the native Amerrican Cultures, did not work with them. The Asian peoples have there own beliefs that also involve religion but obviously at some point decided to work with the animals anyway (logging etc..) So very few people worked with Africans until Asians became less available. Also the old school of elephant training involved abuse (not unlike they way some children were reared until beatings with a belt became unacceptable sadly there are still parents and animal trainers who are abusive...). An African elephant will not tolerate this abuse. It will either retaliate (hurt or kill the offender) or run. The Asian elephant will take more of this (and wait to pay back the abuser later...). So the way elephants are trained has begun to change...The new school involves positive (reward) reinforcement, negative reinforcement etc...Anyway we always say that "you have to be smarter than the elephant". Jon you said "Is there a real philosophical barrier here, or do we just lack the wit to circumvent it?" So by my comment somewhat similar to yours I mean there are a lot people out there without a lot of commmen sense, intelligence or regard for animals and there welfare that are working with elephants (and other animals). They give elephant handlers and trainers a bad name. But of course the sensationism that the Press thrives oon perpetuates this. When people ask me if all elephants are dangerous or neurotic or if all animals trainers are abusive. I ask them if "all white males named Jeffrey are canibals". I realize I have gotten off the track of your message a little but I feel that some understanding of elephants is needed before I say the folowing: I have the privilege of living with these two elephants, very closely. The have accepted me as part of their herd, so to speak. I am not going to claim I can read their minds, or that they can read mine. Perhaps either or both of htose has some truth in it.. I do know that because they accept me and my husband, family etc.. as part of their "family" We have a window into their lives that is releatively rare. There are probably some other people this close to their elephants particularly in the private sector where there are 24 hour days at the facility. I hope to continue in my observations.I also hope to, through these mailing lists, the internet (Ivory Haven's Web Page) and other people I meet, to link up with scientists who have the technical knowledge about studing a species who will be willing to work with me to prove some of the things you are asking. To prove scientifically their intelligence, how they think, how they communicate infrasonically (I have my own observations on that)how they vocalize, communicate etc..etc... I do not have the degree in biology or ethology to be able to write a paper up to the standard of the scientific community. I do not know the appropriate terms in some cases, nor the scientific protocols for proving or disproving something... So I throw this out there once again... I am available to colaborate with someone who wishes to work on there thesis or some other paper regarding of elephants. There technical expertise combines with our years of experience and observations. ( My husband has been working with elephants since 1969). I am sure others must ahve noted this before but my thinking is that perhaps we should start looking for the answers to what goes on inside an animals mind by starting with species that have similar intelligence to ours. Then take what we have learned and perrhaps we will find some answers and methods which will work on the other species as well. Jon, you said " What standards of evidence would we accept concerning other animals' experiences? What are the most promising approaches (neuroscience, communication studies....) and can we envisage new ones that would give a substantial lead (virtual reality, computer-simulated animats, artificial intelligence)? " I would love to work on a study with elephants to help answer some of these questions. In fact I am working with Dr. Marthe Kiley-Worthington of Dept. of Psychology, Washington Singer Labs at the University of Exeter in the UK on some phsychology and animal behavior related subjects. Also with Dr. Hezekial Shoshani a known elephant expert who has published and worked on several books about elephants (Majestic Creatures of the Wild, Elephants, the Deciding Decade to name a few).. There is always room for more....I think that the wonder of it all is what leads to scientific studies....Therefore it should not exclude those who are not scientists.... Jon also said: "Are animal minds really like the insides of black holes, that can never be properly observed from outside? Or do we just have to think real hard about how to do it? Or maybe spend enormous amounts of money and human effort, to explore this inner space?" I say, never say never too... lets explore this inner space from a variety of angles...

Here is one possible approach... I think that the experiment should be designed so that the best analysis can be used. Yes the predator probably scares of the squirrels, but how much?

The moving model/picture would appears contingent on the squirrel entering th patch and noit be available for close inspection...

I am embarassed. I haven't looked for the dictionary meaning of "speculation" but using the word in the common sense I think it is appropriate, after making one's observations, to speculate during the construction of the hypothesis that must finally be tested by experiment. We are doing that. I repeat what I said in reply to Joe Stookey, that I don't dismiss the role of evening quality. There is recent data from IGER( and I hope I remember this correctly) that indicates that grazing activity increases during each day which fits in well. I have suggested that the diurnal changes in quality described might not be universal and for that reason I take the position that I have explained. But I haven't any data on this so I keep an open mind. I used "breakfast" and "dinner" as a gesture to the people who purvey "all the cat and dog stuff". These were not anthropomorpisms though I may have been patronising. You come close to it when you suggest that the animal is "waiting to eat more digestible material in the evening". I quess we could say this would be the result of a learned behaviour and animals here could have long memories. It seems to me that a mechanism that initiates the days grazing at dawn would have significance as a means of minimising activity in darkness. It does not follow that that the animal should graze exclusively in daylight. Fitness is not achieved by uniform perfection in every inherited feature. An animal that took its days feed in one shot would be a strange consruct. I have not found anything in the literature to support my suggestion that bovines respond to light quality. One big reason for putting my original message out was to see what response the suggestion would generate. Your response encourages me. I have been looking at a fairly large data set, our own and other published material. The 3 features of the daily feeding pattern that I described appear to hold for dairy cows, for non-milking heifers and for animals living in semi-feral conditions in the absence of normal livestock farm management routines. A few years ago colleagues of yours said that "despite the intensity of research and modelling of intake and digestion in domestic livestock, there has been little progress in providing a mechanistic account of the factors controlling grazing time, even though this is essential to progress from an understanding of instantaneous intake rate to understanding daily intake. The lack of progress may be because grazing time and daily intake are not subject, in many cases, to purely physical constraints, but may be the consequence of evolved behaviour. It would not be consistent with maximising fitness, for example, to eat without a behavioural limit."(Parsons et al 1994. Functional Ecology). That is the context in which I submitted my original message. Finally, As far as I can see our domestic bovines do not display any patterns of behaviour related to seasonal or lunar cycles. The patterns appear to be circadian and in that case it would not be surprising to find that a light cue such as I have suggested was present as a means of measuring the day. Anthony PS.

It seems very timely in that I have just returned from the annual convention of the APDT (Association of Pet Dog Trainers), and this is a "hot topic" amongst trainers in the US. A similar incident of punishment here has fueled the discussion and has caused the American Humane Association (AHA) to form a task force to formulate humane training standards. They had their third or fourth (I think) work session following APDT. I'd be happy to visit further with you to supply information on either APDT--which stresses positive methods for pet dog training--or the AHA project.

This in itself seems to be the number one key to opening doors. When we have this then we are more able to use the wonderful tools such as the ones science provides to get closer to an understanding of an animal's "worldview". Kinda basic I know, but damn I love how you love those elephants!

The chimpanzees are currently leased to The Coulston Foundation, a biomedical research facility where many questionable chimpanzee deaths have occurred. The Coulston Foundation is currently under investigation by the United States Department of Agriculture (USDA) for violations of the Animal Welfare Act (AWA). The Air Force is planning to relinquish ownership of the chimpanzees and is now considering bids from interested parties. Among the bidders are several groups who want to place the chimpanzees in retirement sanctuaries where they can live out the rest of their lives in peace. One such group is the Institute for Captive Chimpanzee Care which has Dr.Jane Goodall on its Board of Directors. The Coulston Foundation has also bid on the chimpanzees, despite their negligent management record. We, the undersigned, ask the Air Force to give all 143 chimpanzees to groups who will place them in retirement, resocialise them, and provide them with enriched environments.

We think that the cattle we work with would respond to thermal stress in the same way and that there would be compensation elsewhere in the day. We have re-ordered our thoughts a bit following the exchanges that have taken place. The pattern of feeding that we observe might be seen to consist of two cycles. There is a big daily cycle with little or no grazing during darkness and increasing activity after dawn leading to a peak in activity around sunset and then the cycle is repeated. Within this big cycle there is a smaller scale cycle of alternating periods of grazing and not grazing(ruminating). It occurs to me that the big daily cycle would have an associated metabolic cycle which lags some hours behind the intake cycle. The lag would reflect the time involved in digestion and absorption. The feeding pattern that we observe may be a response to the metabolic cycle. We are familiar with the idea that satiety affects bout grazing activity. In 1992 Tolkamp and Ketelaars (Livestock Production Science - 3 papers) proposed , on the basis of scrutiny of a large body of published data, that daily intake is controlled by an optimisation target at the whole animal level and that the animal was capable of controlling intake rate. In the period of the day where thermal stress occurs it is possible that the animal is still on the "high" part of the daily cycle and the grazing switch may be trembling close to the "off" position. It may not be "a big deal" when grazing is suppressed. The relative constancy of total daily grazing time in our data suggested to us that intake is regulated by the animal relative to a target. Regulation implies that the system "knows" time. The light associated feature of the pattern may be involved in that.

Although there were several problems with the design of the experiment, such as not using newly weaned voles (Microtus agrestis), I did find a couple of interesting results. Female voles seemed to show more of an improvement on addition of the grass than the males, in terms of reduced stereotypic frequency, and only females made complex nests with the grass. I put the nesting behaviour down to 'maternal instincts', but I don't think this fully explains why the females showed a greater improvement. Do males and females have a different perception of their environment, and would this affect the way they use different types of enrichment? Has anyone else found this sexual difference, or does anyone know of any other examples of this? I have discovered that female rats are less prone to develop ulcers in conflict inducing situations, and are better at learning active avoidance behaviour than males (Grey, 1987). I was just wondering whether female voles (or other animals) perhaps showed a different type of development or establishment of stereotypies that would make them easier to disrupt using enrichment??????? Any ideas?

Numerous papers have shown sexual differentiation with regards to predation risk and survivorship. This, along with the fact that males and females of almost every species should experience differential energetic costs due egg versus sperm production, leads to the question of whether or not the two sexes and gravid versus non-gravid females perceive and utilize their environment differently. I'm attempting to see if males, gravids, and non-gravid females utilize vegetative cover to the same extent when confronted with a predatory threat. The majority of references I have used deal with gender differences in antipredatory behavior but a good review paper on behavioral trade-offs was put out by Lima and Dill (1990). Another paper that comes to mind looks at the foraging activities of males and females when offered 3 food levels combined with 2 levels of predation risk. It seems to me that if perception differs, behavior should also differ in order to appropriately respond to a variety of environmental conditions without using "unnecessary energy".

The evolutionary psych literature suggests incidental memory to be superi= or in females ... no one asks dad where the lost cap might be. Citations ca= n be found in "The Adapted Mind." Perceptions of sexually desirable partners differ. Rachel Gur has commented that normal males cannot identify anger in photographs of women but are accurate in regard to the other basic emotions. Women are accurate regardless of emotions portrayed. Gur's finding, if real, would make sense in that women appear to counter= male power through alliances with other women and sometimes non-spouse males such as relatives, therapists, or attorneys. Thus, women, to manag= e dispersed alliances more effectively might gain from "annoyance detectors= ." It may be that ANY difference in psychological adaptations reflects like= ly differences in perception -- not in sensory capability so much as in a differential response to varied stimuli. I expect that women might be more sensitive to differences in infant distress calls, for example. Fascinating stuff, lots of "just so" tales, including some of the above. = Justified by heuristics?

Different perceptions of their environment? During sex, men seem to be unconscious of their environment (except, one hopes, their partner) while women notice every little noise ---- including children crying, dogs throwing up, house creaking, etc. This is strictly anecdotal --- not just me, but every one of my female friends has noticed. I have no plans for a PhD paper. I throw this open to the list. Feel free to borrow the idea. I would like a footnote, but it is not absolutely necessary.
