Environmental enrichment in a large animal facility

The cats' favorite toys contained catnip. ... Cats in single cages often expressed physiological signs of boredom like psychogenic alopecia and polyphagia with resultant obesity. Although we gave these cats a variety of playthings, the problem continued. ... We want...

Effect of enrichment and pen size on behavior, productivity and immune response of growing-finishing pigs

Feeding efficiency was higher in pigs housed in enriched pens than in non-enriched pens.

Behaviour of piglets during weaning in a semi-natural enclosure

The findings of the present study generally show that weaning in a semi-natural situation is the result of a gradual process without any dramatic changes to the piglets regarding activity budgets or social relationships.

A comparison of operant responding by farrowing sows for food and nest-building materials

Operant responding for food completely overshadows operant responding for other potential reinforcers both before and after farrowing [because, obviously, food-restricted sows have an extremely high motivation to obtain food]. .. Any potential welfare problems caused by frustration of nest-building behaviour...

Stereotyped behaviour, social interactions and suckling pattern of pigs housed in groups or in single crates

Our observations confirm that providing straw and space for exercise reduced the frequency of stereotypies (14.9 per sow-hour), but did not completely suppress them (0.3 per sow-hour). ... Sows in crates demonstrated more stereotypies, whereas sows in pens had more...

The influence of pen size on toy preference of growing pigs

We conclude that the addition of a soft, pliable, rubber dog toy enriches the environment of confined pigs, and could reduce or alter aggressive and stereotypic behaviors commonly associated with confinement operations.

Behaviour and productivity of the domestic pig in barren and enriched environments

It was shown that pigs housed indoors and given a substrate [peat] to root, increase the amount of time spent exploring and decrease the time spent inactive and in behaviour directed towards their pen-mates such as chewing ears and tails.

Effects of pen size, partial stalls and method of feeding on welfare-related behavioural and physiological responses in group-housed pigs

There may be welfare advantages of housing pigs in pens with partial stalls both in the short term, on the basis of reduced aggression, and in the long term by also feeding in the partial stalls, on the basis of...
