Behavioral abnormalities in captive nonhuman primates
Contributor(s):: Avanti, Mallapur, Choudhury, B. C.
In this study, we dealt with 11 species of non-human primates across 10 zoos in India. We recorded behaviour as instantaneous scans between 9 a.m. and 5 p.m. In the study, we segregated behaviours for analyses into abnormal, undesirable, active, and resting. The 4 types of abnormal behaviour...
Combination therapy reduces self-injurious behavior in a chimpanzee ( Pan troglodytes troglodytes ): a case report
Contributor(s):: Bourgeois, S. R., Vazquez, M., Brasky, K.
Self-injurious behavior (SIB) remains a severe and intractable abnormal behavior for nonhuman primates in diverse settings and is a significant concern for veterinarians and behavioral scientists. To date, no single pharmacological, behavioral, social, or environmental intervention method has...

Contributor(s):: Cottam, N., Dodman, N. H., Moon-Fanelli, A. A., Patronek, G. J.
To investigate the validity of remote consultation for treatment of canine separation anxiety, this study compared the efficacy of 2 types of behavioral services offered by Tufts Cummings School of Veterinary Medicine (TCSVM): (a) "PetFax," a remote consultation service in which dog caregivers...
Distressed animal behaviors and some recommendations for improvements at the Kuala Lumpur Zoo, Malaysia
Contributor(s):: Amber, Haque
The artificial living conditions of captive animals present numerous challenges for animal caretakers. In this study I explored abnormal behaviors in certain caged animals at the Kuala Lumpur Zoo. Findings obtained from observations of animals and interviews of the zoo staff are followed by...
Frustrated appetitive foraging behavior, stereotypic pacing, and fecal glucocorticoid levels in snow leopards ( Uncia uncia ) in the Zurich Zoo
Contributor(s):: Burgener, N., Gusset, M., Schmid, H.
This study hypothesized that permanently frustrated, appetitive-foraging behavior caused the stereotypic pacing regularly observed in captive carnivores. Using 2 adult female snow leopards (U), solitarily housed in the Zurich Zoo, the study tested this hypothesis experimentally with a novel...
Pair housing for female longtailed and rhesus macaques in the laboratory: behavior in protected contact versus full contact
Contributor(s):: Baker, K. C., Crockett, C. M., Lee, G. H., Oettinger, B. C., Schoof, V., Thom, J. P.
Pair housing for caged macaques in the laboratory generally allows unrestricted tactile contact but, less commonly, may involve limited contact via grooming-contact bars or perforated panels. The purpose of using this protected contact housing, which prevents entry into pair-mates' cages,...
Pet owners' views of pet behavior problems and willingness to consult experts for assistance
Contributor(s):: Shore, E. R., Burdsal, C., Douglas, D. K.
Prior research has found that dog obedience training and the receipt of advice regarding companion animal (pet) behavior reduce the risk of nonhuman animal relinquishment to an animal shelter and increase human-companion animal interactions, but research also finds that only a minority of pet...
Self-biting in caged macaques: cause, effect, and treatment
Contributor(s):: Reinhardt, V., Rossell, M.
Injurious self-biting is one of the most serious problems in primate colonies (Niemeyer, Gray, & Stephen, 1996). "Approximately 10% of captive, individually-housed monkeys engage in the disturbing phenomenon of self-injurious behavior (SIB). To date, no adequate explanation or effective therapy...
A case control study of on-farm risk factors for tail biting in pigs

Behavioural and physiological responses of horses to initial training: the comparison between pastured versus stalled horses
Contributor(s):: Rivera, E., Benjamin, S., Nielsen, B., Shelle, J., Zanella, A. J.
Horses kept in stalls are deprived of opportunities for social interactions, and the performance of natural behaviour is limited. Inadequate environmental conditions may compromise behavioural development. Initial training is a complex process and it is likely that the responses of horses may be...
Behavioural effects of environmental enrichment for individually caged rabbits
Contributor(s):: Lidfors, L.
The behavioural effects of providing 60 male New Zealand laboratory rabbits with one of four objects in their individual cages as environmental enrichment were investigated. The rabbits were assigned to one of 5 treatments by a random procedure; hay in a water bottle, grass-cubes, two gnawing...
Development of stereotypies and polydipsia in wild caught bank voles ( Clethrionomys glareolus ) and their laboratory-bred offspring. Is polydipsia a symptom of diabetes mellitus?
Contributor(s):: Schoenecker, B., Heller, K. E., Freimanis, T.
The development of stereotypies and polydipsia was studied in wild caught bank voles (P: n=92) and their laboratory-bred offspring (F1: n=248). All animals were kept isolated in barren cages in the laboratory. In the P generation, no individuals developed stereotypies, but 22% developed...
Divergent selection on feather pecking behaviour in laying hens ( Gallus gallus domesticus )
Contributor(s):: Kjaer, J. B., Sorensen, P., Su, G.
A selection experiment was initiated in 1996 in which selection for (HP line) and against (LP line) feather pecking was performed. The foundation stock was a White Leghorn layer strain established in 1970 and maintained since then as a random bred control line at the Institute. Six hatches were...

Contributor(s):: Widowski, T., Mench, J.
This special issue of Applied Animal Behaviour Science contains topics on the International Society for Applied Ethology (ISAE) congress. The 8 topics include (1) human-animal interactions in livestock production; (2) applied and basic research in farm animal welfare; (3) transferring the results...
Motivational and physiological analysis of the causes and consequences of non-nutritive sucking by calves
Contributor(s):: Passille, A. M. de, Rushen, J.
Non-nutritive sucking by calves of an artificial, dry teat was examined. Most non-nutritive sucking occurred directly after a meal and was elicited by the taste of milk. Increasing the volume of milk drunk did not reduce the amount of non-nutritive sucking, suggesting that the consumption of milk...
Resting and social behaviour of dairy heifers housed in slatted floor pens with different sized bedded lying areas
Contributor(s):: Nielsen, L. H., Mogensen, L., Krohn, C., Hindhede, J., Sorensen, J. T.
The hypothesis that an increase in the straw bedded resting area for group housed heifers would increase synchronization of resting behaviour and decrease aggressive and abnormal behaviour was tested. An experiment was conducted on 2 Danish commercial dairy farms with 20 Danish Friesian heifers...
Stereotypies in heifers are affected by feeding regime
Contributor(s):: Redbo, I., Nordblad, A.
The effect of giving different types of food which result in long or short feeding durations on stereotypy levels was studied. Forty-eight tethered heifers of the Swedish Red and White Breed, with an average age of 16 months, were subjected to the same treatment. During the first 2 weeks of the...
The effects of weaning at 7, 14 and 28 days on piglet behaviour
Contributor(s):: Worobec, E. K., Duncan, I. J. H., Widowski, T. M.
The effects of very early weaning on piglet behaviour were investigated. In order to determine the effects of weaning age on piglet behaviour, litters of piglets were randomly assigned to be weaned at 7, 14 and 28 days of age. In each of 3 trials, piglets from 3 litters were mixed into 2 pens of...
The use of mirrors for the control of stereotypic weaving behaviour in the stabled horse
Contributor(s):: McAfee, L. M., Mills, D. S., Cooper, J. J.
Weaving, a common locomotor stereotypy, is associated with social isolation in stabled horses. In this study we investigated the effect of provision of mirrors on weaving as this may have a similar effect to access to conspecifics. The behaviour of 6 known weavers, each in 1 of 3 locations within...
