  1. Adopter-dog interactions at the shelter: Behavioral and contextual predictors of adoption

    Contributor(s): Protopopova, Alexandra, Wynne, Clive David Lawrence

    Millions of unwanted pets enter animal shelters each year in the USA, but only a portion leave alive. Previous research has found that morphology and in-kennel behavior influence adoption. The current study evaluated whether any behaviors exhibited by dogs during an out-of-kennel interaction with...

  2. Advances in Applied Zoo Animal Welfare Science

    Contributor(s): Ward, Samantha J., Sherwen, Sally, Clark, Fay E.

    Nonhuman animal welfare science is the scientific study of the welfare state of animals that attempts to make inferences about how animals feel from their behavior, endocrine function, and/or signs of physical health. These welfare measurements are applicable within zoos yet inherently more...

    Full-text: Available

    Journal Articles | Contributor(s): Chen, F. L., Zimmermann, M., Hekman, J. P., Lord, K. A., Logan, B., Russenberger, J., Leighton, E. A., Karlsson, E. K.

    The ancient partnership between people and dogs is struggling to meet modern day needs, with demand exceeding our capacity to safely breed high-performing and healthy dogs. New statistical genetic approaches and genomic technology have the potential to revolutionize dog breeding, by...

  4. Affiliative behaviour of related and unrelated pairs of cats in catteries: a preliminary report

    Journal Articles | Contributor(s): Bradshaw, J. W. S., Hall, S. L.

    Affiliation between 11 unrelated pairs of cats from the same household were was compared with that of 14 pairs of littermates, by observing their behaviour while confined in catteries.

  5. Agent-based modelling in applied ethology: An exploratory case study of behavioural dynamics in tail biting in pigs

    Journal Articles | Contributor(s): Boumans, Iris J. M. M., Hofstede, Gert Jan, Bolhuis, J. Elizabeth, de Boer, Imke J. M., Bokkers, Eddie A. M.

    Understanding behavioural dynamics in pigs is important to assess pig welfare in current intensive pig production systems. Agent-based modelling (ABM) is an approach to gain insight into behavioural dynamics in pigs, but its use in applied ethology and animal welfare science has been limited so...

  7. Aggression and social spacing in light horse ( Equus caballus ) mares and foals

    Journal Articles | Contributor(s): Weeks, J. W., Crowell-Davis, S. L., Caudle, A. B., Heusner, G. L.

    Aggression and social spacing were studied in 14 light horse mares and their foals living at pasture. Focal samples were collected on each mare-foal dyad for 6 to 10.5 h from 2 months of foal age until weaning at approximately 4 months of age. Observations on foals continued until approximately 6...

  8. Aggression, fearfulness and coping styles in female pigs

    Journal Articles | Contributor(s): Janczak, A. M., Pedersen, L. J., Bakken, M.

    The coping styles hypothesis states that animals have consistent behavioural and physiological coping responses that can be characterised on a continuum from reactive to proactive. According to this hypothesis, animals can be characterised by consistency in responses across social and non-social...

  9. Aggressive behavior in two different group-housing systems for pregnant sows

    Journal Articles | Contributor(s): Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Gasa, J., Baucells, M. D., Manteca, X.

    The study housed 120 pregnant sows from Day 29 of pregnancy to 1 week before parturition either in groups of 10 with trickle feeding (TRICKLE) or in groups of 20 with an unprotected electronic sow feeding (FITMIX). The study recorded aggressive interaction on 11 nonconsecutive days. Frequency of...

  10. Aggressive conflicts amongst dogs and factors affecting them

    Journal Articles | Contributor(s): Roll, A., Unshelm, J.

    Over one year, 206 dog owners were questioned in a veterinary clinic. The survey included two groups: 151 owners who visited the clinic because of an injury to their dog caused by another dog and 55 people who owned dogs that caused injuries to others. The questioning served to compare aggressors...

    Whether man can live in harmeny with his environment depends in great measure en his ability to' live with his fellew man. Can man learn to' engineer human seciety in time to' prevent a helecaust? Mere specifically, can we learn to' prevent aggressien er to' channel it harmlessly? The ethelegist...

  12. Aggressiveness in group-housed rabbit does: Influence of group size and pen characteristics

    Journal Articles | Contributor(s): Zomeño, Cristina, Birolo, Marco, Zuffellato, Andrea, Xiccato, Gerolamo, Trocino, Angela

    The aim of this work was to study how the group size and the number of doorways in a pen may influence the aggressive interactions throughout the reproductive cycle among does kept in a part-time group housing system. Thirty-two crossbred multiparous pregnant rabbit does were housed in individual...

  13. Agility and search and rescue training differently affects pet dogs' behaviour in socio-cognitive tasks

    Journal Articles | Contributor(s): Marshall-Pescini, S., Passalacqua, C., Barnard, S., Valsecchi, P., Prato-Previde, E.

  14. Agonistic behaviour and feather pecking in single-sexed and mixed groups of laying hens

    Journal Articles | Contributor(s): Oden, K., Vestergaard, K. S., Algers, B.

    The effects of the presence of males on female aggressiveness and feather pecking in groups of about 500 laying hens housed in an aviary system were studied. In all, 10 groups of ISA Brown laying hens were observed at 21, 35, 45 and 55 weeks of age on 2 farms, during 2 years. In the second year,...

    Journal Articles | Contributor(s): Coppedge, B. R., Carter, T. S., Shaw, J. H., Hamilton, R. G.

    Aggressive interactions of 43 bison calves (10 months old) released motherless into a 288-member resident bison population of mixed composition were observed. Based on expected observations of aggressive interactions from chi superscript 2 analyses, these 'orphan' calves were recipients of...

  16. Agonistic interactions and physiological reactions of top- and bottom-ranking pigs confronted with a familiar and an unfamiliar group: preliminary results

    Journal Articles | Contributor(s): Otten, W., Puppe, B., Stabenow, B., Kanitz, E., Schon, P. C., Brussow, K. P., Nurnberg, G.

    Four trials were carried out, where in each trial during a selection test 2 groups of growing pigs (12 weeks old) with 9 animals each were randomly formed. After a week, the top (TR) and bottom (BR) ranking pig from each group was isolated and kept under single housing conditions. At the age of...

  17. All a mother's fault? Transmission of stereotypy in striped mice Rhabdomys

    Journal Articles | Contributor(s): Jones, M., Lierop, M. van, Pillay, N.

    Environmentally induced stereotypy is the most common abnormal behaviour in captive animals. However, not all animals housed in identically impoverished environments develop stereotypy, possibly because of differences in genetic predisposition. To investigate the transmission of stereotypy in...

  19. Alone but not always lonely: Social cues alleviate isolation induced behavioural stress in wild zebrafish

    Journal Articles | Contributor(s): Daniel, Danita K., Bhat, Anuradha

    Social isolation has been routinely used for experimental studies on many animal model systems. Additionally, considering the recent increase in the prevalence of isolation in the human population, it has become even more imperative to understand social isolation and measures that might alleviate...

  20. Altered aggression in different sized groups of crayfish supports a dynamic social behaviour model

    Journal Articles | Contributor(s): Patullo, B. W., Baird, H. P., Macmillan, D. L.

    Living in groups with conspecifics can increase an animal's fitness in the wild. A social environment may also be imposed by commercial farming industries. One important measure of competition and group dynamics is the level of aggressive interaction. This can also influence the level of damage...
