Conflict and reconciliation behavior trends of the bottlenose dolphin ( Tursiops truncatus )
Contributor(s):: Holobinko, A., Waring, G. H.
Wild bottlenose dolphin (Tursiops truncatus) populations display societal structures characterized by numerous and frequent changes in group composition, complex social relationships, and high levels of cooperation, attributes also observed in human and nonhuman primate cultures. Maintaining...
Human-animal interaction, stress, and embryo production in Bos indicus embryo donors under tropical conditions
Contributor(s):: Macedo, G. G., Zuccari Neto, C. E. S., Abreu, U. G. P. de, Negrao, J. A., Costa e Silva, E. V. da
This study investigated the effect of human-animal interaction (HAI) and the stress response on the quality of embryo production in superovulated Nelore (Bos indicus) cattle, under tropical conditions. Thirty-two females underwent a superovulation protocol for 5 days. Cortisol concentrations were...

A cross-cultural comparison of reports by German Shepherd owners in Hungary and the United States of America
Contributor(s):: Wan, M., Kubinyi, E., Miklosi, A., Champagne, F.
Cross-cultural comparisons of dog behavior and dog-keeping practices are limited. The current study compared the questionnaire responses of German Shepherd owners in Hungary and the United States of America (USA). Owners provided information about their dog-keeping practices, as well as reports...
Personalities in female domesticated pigs: behavioural and physiological indications
Contributor(s):: Ruis, M. A. W., Brake, J. H. A. te, Burgwal, J. A. van de, Jong, I. C. de, Blokhuis, H. J., Koolhaas, J. M.
A total of 128 gilts from 31 sows were systematically studied from birth to slaughter in two identical trials. Intra-test consistency in individual behavioural and/or physiological reactions was studied in three different tests. There were no consistencies in reactions of gilts over time to a...
Predicting tail-biting from behaviour of pigs prior to outbreaks
Contributor(s):: Statham, P., Green, L., Bichard, M., Mendl, M.
Predicting that an outbreak of tail-biting is going to occur in a group of pigs would be a useful tool for farmers. In a prospective longitudinal study, 24 groups of c.30 undocked pigs were followed from birth to slaughter weight. Four groups had to be excluded from the analysis, the remaining...
Space use as an indicator of enclosure appropriateness: a novel measure of captive animal welfare
Contributor(s):: Ross, S. R., Schapiro, S. J., Hau, J., Lukas, K. E.
Empirical measures of animal behavior and space use within the captive environment can provide critical information about animals' requirements, preferences and internal states. The trend toward naturalistic environments has shown promise in terms of behavioral benefits for animals such as great...
Behavioural time budgets of broiler chickens reared in varying light intensities
Contributor(s):: Alvino, G. M., Archer, G. S., Mench, J. A.
Light management is a critical component of production for intensively housed animals. To increase productivity, broiler chickens are often raised commercially in houses that are dimly illuminated on a near-continuous basis. There have been relatively few studies examining the effects of light...
Reliability of temperament tests on finishing pigs in group-housing and comparison to social tests
Contributor(s):: Brown, J. A., Dewey, C., Delange, C. F. M., Mandell, I. B., Purslow, P. P., Robinson, J. A., Squires, E. J., Widowski, T. M.
If variation in behaviour is consistent within individuals and reliably associated with relevant welfare measures, this variation could aid in genetic selection, or development of management schemes designed to improve welfare. In this study, we focused on temperament tests in group-housed...
Potential behavioural indicators of post-operative pain in male laboratory rabbits following abdominal surgery
Contributor(s):: Farnworth, M. J., Walker, J. K., Schweizer, K. A., Chuang, C. L., Guild, S. J., Barrett, C. J., Leach, M. C., Waran, N. K.
This study aimed to identify behaviours that could be used to assess post-operative pain and analgesic efficacy in male rabbits. In consideration of the 'Three Rs', behavioural data were collected on seven male New Zealand White rabbits in an ethically approved experiment requiring abdominal...
