Castration promotes welfare in group-housed male Swiss outbred mice maintained in educational institutions

Educational institutions maintain group-housed mice of both sexes for training veterinarians and technicians in husbandry, medication, and sampling procedures. Mice kept in all-male groups may experience poor welfare due to fighting. Castrated mice may be used to replace gonadally intact...

Social context and other factors influence the behavioural expression of pain by lambs

There is evidence that the presence of a conspecific can alter the experience of pain in humans and other animals. This ‘social buffering' may be mediated by factors such as relatedness and familiarity. This study investigates whether and how the...

Evaluation of analgesic efficacy in piglets using a novel pig grimace scale

There is a critical lack of information surrounding methods to improve the wellbeing of piglets undergoing painful procedures. It is not uncommon for piglets to undergo potentially painful procedures without anesthesia or analgesia, particularly for agricultural research projects. The objectives...

Plumage damage in free-range laying hens: Behavioural characteristics in the rearing period and the effects of environmental enrichment and beak-trimming

Severe feather-pecking, whereby birds peck at and pull out the feathers of other birds, is one of the greatest welfare concerns and the most prevalent behavioural problem in laying hens. It can be extremely difficult to control, especially in non-cage...
