A brief report on intraspecies aggressive biting in a goat herd
Contributor(s):: Tolu, C., Savas, T.
This study aimed at analysing the effects of age, horn and places on biting and butting as intraspecies aggressive activities. Seventy-two Turkish Saanen goats were used as animal material and 22,686 aggressive behaviours were recorded in different places from a total of 118 h direct observation....
The implications of compound chew-bite jaw movements for bite rate in grazing cattle
Contributor(s):: Ungar, E. D., Ravid, N., Zada, T., Ben-Moshe, E., Yonatan, R., Baram, H., Genizi, A.
Many aspects of the management of grazing systems are directly or indirectly related to the rate of herbage intake achieved by the animal. Intake rate depends, in part, on the time budget of the process, which derives from the basic behavioural component - the jaw movement. Chewing and biting jaw...
Aggression in replacement grower and finisher gilts fed a short-term high-tryptophan diet and the effect of long-term human-animal interaction
Contributor(s):: Poletto, R., Meisel, R. L., Richert, B. T., Cheng, H. W., Marchant-Forde, J. N.
Aggression can be a major problem for swine production as it negatively impacts the pigs' health and welfare. Increasing tryptophan (TRP) intake to raise brain serotonin (5-HT) - key for aggression control, and long-term positive social handling can reduce stress in pigs. Objective was to...
The quality of the relation between handler and military dogs influences efficiency and welfare of dogs
Contributor(s):: Lefebvre, D., Diederich, C., Delcourt, M., Giffroy, J. M.
Over the last 10 years, the influence of the dog-owner relationship on dog behaviour has received growing attention, unlike the working dog handler's relationship. Using a questionnaire addressed to the 430 dog handlers of the Belgian army in 2001 (303 respondents), this study investigated the...
Utility of social network analysis for primate behavioral management and well-being
Contributor(s):: McCowan, B., Anderson, K., Heagarty, A., Cameron, A.
New management strategies for detecting social instabilities and promoting social cohesion are needed to reduce aggression-based morbidity and mortality among captive groups of rhesus macaques. This study was conducted to determine the utility of social network analysis for deciphering patterns...
Vulva biting in group-housed sows: preliminary report
Contributor(s):: Putten, G. van, Burgwal, J. A. van de
The aggressive vice of vulva biting is primarily induced by the sows queuing up at the entrance to the computer-controlled feeding station, and so methods were investigated to reduce the relative importance of this station. Also, the predictability of the feeding systems was improved. Among the...
A video and acoustic methodology to map bite placement at the patch scale
Contributor(s):: Griffiths, W. M., Alchanatis, V., Nitzan, R., Ostrovsky, V., Ben-Moshe, E., Yonatan, R., Brener, S., Baram, H., Genizi, A., Ungar, E. D.
Bite placement plays an important role in determining the mean weight of bites removed from a patch, and hence intake rate. This paper describes a video and acoustic methodology to map the sequential placement of bites on the sward surface. The methodology was evaluated for dairy heifers grazing...
Aggression between unacquainted pigs - sequential assessment and effects of familiarity and weight
Contributor(s):: Jensen, P., Yngvesson, J.
Staged paired encounters between 74 pairs of 7-8 weeks old unacquainted piglets were studied. In 37 of the pairs, the pigs were pre-exposed to their opponents by keeping them for 24 h in small pens separated by wire net. The controls were kept in the same pen, separated by solid wooden walls. In...
An overview of types of aggressive behaviour in dogs and methods of treatment

Case reports on defensive behaviour in equine and bovine subjects in response to vocalization of the common vampire bat ( Desmodus rotundus )
Contributor(s):: Delpietro, H. A.
Field observations showed that cattle and horses reacted defensively on hearing the vocalization of the common vampire bat (Desmodus rotundus) in their locality. The animals generally moved away from the place where the bats were heard, breaking up the group and dispersing to open areas of the...
Face flies ( Musca autumnalis De Geer) and the behavior of grazing beef cattle
Contributor(s):: Dougherty, C. T., Knapp, F. W., Burrus, P. B., Willis, D. C., Bradley, N. W.
Zero, 400 or 800 laboratory-reared adult face flies (Musca autumnalis De Geer), which had been deprived of nutrients and water for 12 h, were released in large (5 m x 5 m x 2 m) screened enclosures each containing one tethered adult Angus beef cow (Bos taurus) grazing tall fescue (Festuca...
Patch selection by cattle: maximization of intake rate in horizontally heterogeneous pastures
Contributor(s):: Distel, R. A., Laca, E. A., Griggs, T. C., Demment, M. W.
Three 5-year-old oesophageally fistulated Hereford steers were grazed on ryegrass pastures with patches of short-dense and tall-dense pasture, short-dense and short-sparse pasture, or short-dense and tall-sparse pasture. Bite weight was greatest in tall- and short-dense patches and smallest in...

A pilot study to evaluate an elementary school-based dog bite prevention program
| Contributor(s):: Spiegel, I. B.
The primary objective of this program evaluation was to determine if a school-based education program is an effective means of informing elementary school-aged children enrolled in second through fourth grades about dog bite safety - the awareness of proper behavior when in the company of dogs to...
An evaluation of a pet ownership education program for school children
| Contributor(s):: Coleman, G. J., Hall, M. J., Hay, M.
Children aged 5 to 6 years are disproportionately susceptible to dog bite attacks relative to the adult population and there is a need to provide them with well-validated education programs to teach correct behaviour when interacting with dogs. The main aim of this study was to assess the...
Dog on a tightrope: the position of the dog in British society as influenced by press reports on dog attacks (1988 to 1992)
| Contributor(s):: Podberscek, A. L.
Five major British daily newspapers (4 broadsheets and 1 tabloid) and their related Sunday editions were monitored over a 5-year period (1988 to 1992 inclusive) to locate articles on dog attacks on humans. From 1989 to 1991 (inclusive) there was intense media interest in dog attacks whereas 1988...
Report on the potentially dangerous dog program: Multnomah County, Oregon
| Contributor(s):: Oswald, M.
In April 1986, a 5-year-old boy was fatally mauled by a pit bull terrier in Multnomah County, Oregon. In June 1986, a new law was passed that identifies and regulates potentially dangerous dogs. In the first 3 years of the program, 1652 dogs were classified as potentially dangerous, and...
A descriptive survey of the range of injuries sustained and farmers' attitudes to vulva biting in breeding sows in south-west England
| Contributor(s):: Rizvi, S., Nicol, C. J., Green, L. E.
The within-farm prevalence of vulva biting in breeding sows in south-west England was investigated using a postal survey sent to 410 pig farmers in January 1997. The response rate was 65% and there were 83 usable replies. The majority of farms where vulva biting was reported indicated a low...
Tail and ear biting lesions in pigs: an epidemiological study
| Contributor(s):: Smulders, D., Hautekiet, V., Verbeke, G., Geers, R.
Tail and ear biting lesions have a negative effect both on the animal welfare status of pigs (Sus scrofus) and the economical revenue of the pig farm. Tail biting behaviour is an unpredictable, abnormal behaviour that is thought to have a multifactorial origin. On-farm factors influencing tail...
