Discrimination of odours from stressed rats by non-stressed rats

Placing a rat into a new cage triggers release of corticosterones. This endocrine response is augmented if the new environment is one in which other rats had previously been subjected to stress.

Deep woodchip litter: Hygiene, feeding, and behavioral enhancement in eight primate species

Sixty-seven animals from eight primate species were used to assess improved husbandry techniques. The presence of woodchips as a direct-contact litter decreased inactivity and fighting, and increased time spent on the ground. Placing food in the deep litter led to...

Allowing captive primates to forage

A woodchip litter substrate reduces abnormal behaviours, primarily self-aggression, and encourages foraging, even in the absence of grain. Comparison between the bare floor and litter with grain showed that in the latter monkeys foraged more, manipulated the environment less, were...

Communication during suckling in the domestic pig

Fan noise disrupted communication between sows and piglets during nursing, resulting in slower piglet growth. Certain indications were found that suggested that the noise-exposed piglets gained less milk than the ones in the silent environment.

Low light intensity decreases the fertility of Callithrix jacchus

Improvement of the light fixtures in both rooms doubled the lighting force and increased the breeding rate during the following 12 months approximately 20% in the upper and 130% in the lower cages.

Food distribution, dominance, and aggressive behaviours in bonnet macaques

Dispersing the food throughout the enclosure, rather than distributing it in one location, resulted in a decrease in agonistic interactions.

Observations on a caging system for housing stump-tailed macaques
