Brain gene expression differences are associated with abnormal tail biting behavior in pigs

Knowledge about gene expression in animals involved in abnormal behaviors can contribute to understanding of the underlying biological mechanisms. The present study aimed to explore the motivational background to tail biting, an abnormal injurious behavior and severe welfare problem in pig production. Affymetrix microarrays were used to investigate gene expression differences […]

Outcry over new Victoria dog laws

Veterinary groups have been highly critical of Victorian laws which led to two dogs being euthanased. The dogs, named Bear and Kooda, were destroyed in June under Victoria’s new dangerous dog laws following a legal battle to save them.

How abnormal is the behaviour of captive, zoo-living chimpanzees?

How abnormal is the behaviour of captive, zoo-living chimpanzees? BACKGROUND: Many captive chimpanzees (Pan troglodytes) show a variety of serious behavioural abnormalities, some of which have been considered as possible signs of compromised mental health. The provision of environmental enrichments aimed at reducing the performance of abnormal behaviours is increasingly […]
