Subject: Self-cleaning in cattle From: Andrea Ribeiro Date: Wed, 02 Apr 2008 10:20:33 -0300 (ART) To: applied-ethology@usask.ca Dear all, We are working in a new project about tick resistance in beef cattle. Does anyone has any references or literature about self-cleaning activity in cattle? I couldn't find much about it ! Thanks, Andrea R.

Subject: RE: Self-cleaning in cattle From: Ray Stricklin Date: Thu, 03 Apr 2008 12:08:22 -0400 To: andrearbr@yahoo.com.br, applied-ethology@usask.ca When you say “self-cleaning” in cattle, are you referring primarily to grooming? Ben and Lynette Hart did quite a lot of work on grooming in African ungulates as related to ectoparasites. I would suggest their work has at least some relevance to understanding the issue in domestic cattle. (But I think they contend that cattle are not as active in grooming as are their wild counterparts?) Below are a few abstracts related to their work: http://www.annalsnyas.org/cgi/content/abstract/916/1/565 http://www.blackwell-synergy.com/doi/abs/10.1111/j.1749-6632.1988.tb38625.x http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6W9W-45NHYD4-21&_user=961305&_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_acct=C000049425&_version=1&_urlVersion=0&_userid=961305&md5=4541c8e59037e14e6e9a32906e2d6508 Best regards, Ray Stricklin From: Andrea Ribeiro [mailto:andrearbr@yahoo.com.br] Sent: Wednesday, April 02, 2008 9:21 AM To: applied-ethology@usask.ca Subject: Self-cleaning in cattle Dear all, We are working in a new project about tick resistance in beef cattle.

Subject: Re: Response to dementia in old (companion) animals From: peterhaskins Date: Mon, 07 Apr 2008 18:50:35 +1000 To: "M. Dew" CC: ethology From: "M. Dew" > I have a 12-yr old female GSD who started displaying behaviors* suggesting the onset of CCD (Canine Cognitive Dysfunction) last year. For the 1st 6 years of her life, she was confined to a backyard by herself surrounded by a privacy fence and fed inexpensive, corn-based kibble. I suspect that if her previous owners had properly socialized her and provided adequate nutrition during her developing years, she wouldn't be as bad as she is now, > We had a Kelpie who showed increasing 'confusion' as he aged. Admittedly he also had impaired vision and hearing. But he'd had a good life from birth -- had been very loved, well-socialised and trained. And well fed -- with Barf, that kept him looking young and alert up to his twelfth year. He died at 15. In his last year we used to have to confine him when we were not home as he would lose himself and just stand wherever he happened to be. we used to have to go searching for him ,and go up to him and tap him on the shoulder to get his attention. at foirst the other dogs showed aggression to him, but then they simply got used to the fact that Sam was as likely to walk over the top of the bone they were eating and simply wait for him to move on. I think that his quality of life was good, until he developed an illness thast would have required hospitalisation -- we decided to not subject him to this. However I suspect that, in a different household, his quality of life could have ben awful -- too many people will dump their old dogs when they begin to show such ill-effects -- subjecting the dogs to a traumatic spell in the pound before a lonely death. (We saw here a couple of months ago a Kelpie bitch, seriously affected by mange, who had obviously been abandoned in an areas she didn't know. She'd obviously had pups before. Poor little dog. I feel bad that I could not save her.) Jenny H Coffs Australia Subject: neighbour effect on stereotypies in horses From: Anna Olsson Date: Sun, 13 Apr 2008 14:39:35 +0100 To: APPLIED-ETHOLOGY@sask.usask.ca Wasn't there a discussion on this topic a few months ago? New paper just out on the topic: Possible influence of neighbours on stereotypic behaviour in horses Applied Animal Behaviour Science, , Volume 111, Issues 3-4, June 2008, Pages 321-328 Krisztina Nagy, Aniko Schrott, Peter Kabai Abstract Revealing risk factors of abnormal stereotypic behaviour (ASB) in horses can help in the design of protective measures. Previous epidemiological studies indicate that social isolation, housing, management conditions, and feeding regime have a strong effect on developing ASB. The common belief that exposure to a stereotypic horse increases the risk of ASB has never been substantiated. Here we report that a generalised linear mixed models (GLMM) analysis of data on 287 horses of nine riding schools revealed that exposure to a stereotypic neighbour is a significant risk factor for performing stereotypy. Also, aggressive behaviour towards other horses increased the odds of stereotypy in the aggressor. These correspondences are unlikely to be a riding-school effect, because riding schools were treated as random factor in the GLMM. Risk factors identified by epidemiological studies cannot be treated as causal agents without independent evidence. Our aim in presenting these findings was to draw attention to the possibility of neighbour effects so that other researchers would include this variable in their surveys. -- Dr Anna Olsson Researcher Laboratory Animal Science Institute for Molecular and Cell Biology Rua Campo Alegre 823 4150-180 Porto, Portugal ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Feierman" Date: Mon, 14 Apr 2008 18:21:44 -0600 To: applied-ethology@sask.usask.ca Brady, What are your specific interests related to animal behavior and ethology? Many of us in this field have had very different routes to get there. Are you interested in an academic career or an applied career? What's your GPA, as that may limit what you want to do in grad school. What was your undergraduate major?
