Relationships between rearing enrichments, range use, and an environmental stressor for free-range laying hen welfare

Enrichments during pullet rearing may improve adaptation and welfare of hens as they move from indoor rearing to a free-range system. Individual variation in outdoor ranging may also affect welfare. This study assessed the effects of rearing enrichments and an...

Rabbits, Guinea Pigs and Mice.

We, the people involved in animal care, are trying to develop improved methods of keeping our animals, methods which will take into account more of the animals' behavioral needs. We now have a large number of rabbits in runs which...

Individually ventilated cages severely attenuate inter-cage ultrasonic vocalizations in rats

Individually ventilated cages (IVCs) benefit rodent and researcher health but may limit animals’ ability to communicate with cage-neighbours via ultrasonic vocalizations (USVs). Despite USVs’ importance in rodent social behaviour, no previous research has investigated IVCs’ impact on between-cage USV transmission....

Dairy cows prefer cubicles with a 3% versus 10% slope

Cows rest 8–16 hours a day to reduce energy expenditure, optimize digestion, and promote recovery. The cubicle’s slope is crucial for cow comfort and proper positioning during rest. This study evaluated dairy cow preferences for two cubicle slopes (3% vs....

Behavior and safety in the use of canopy bridges by howler monkeys in an experimental environment

Urban sprawl advances over forested areas and threatens arboreal species, which often use roads, power lines, and rooftops to move, resulting in roadkill, electrocution, and dog attacks. One measure to mitigate these risks is the installation of canopy bridges, which...
