High-fiber diets in pregnant sows: Digestive utilization and effects on the behavior of the animals

Multiparous sows fed a high-fiber diet required more time to consume their daily feed ration, were quieter, and exhibited fewer nonfeeding oral behaviors.

The influence of different feeding arrangements and food type on competition at feeding in pregnant sows

A feeding arrangement with body partitions resulted in the least aggression and displacements at trough compared to a situation with shoulder or no partition.

Effects of environmental enrichment on behavioral responses to novelty, learning, and memory, and the circadian rhythm in cortisol in growing pigs

At 9 weeks of age enriched and barren housed pigs did not differ in baseline salivary cortisol concentrations nor in circadian rhythm, but at 22 weeks of age barren housed pigs had a blunted circadian rhythm in salivary cortisol as...

Can ambient sound reduce distress in piglets during weaning and restraint? Journal of Applied Animal Welfare Science 3, 107-116

The present results suggest that playing music or other sound provides no improvement in conditions for piglets during handling and weaning.

Feeding motivation and stereotypies in pregnant sows fed increasing levels of fibre and/or food

No reduction in feeding motivation of sows fed high-fibre diets could be measured by operant conditioning tests, but very high levels of fibre (very high-fibre, 29% ADF, 50% NDF, 4.5 kg/day) were effective in reducing stereotypic behaviors and general activity...

The effect of environmental enrichment on learning in pigs

This study examined the effects of enriching the environment on the learning abilities of growing pigs. Eighty-four pigs were housed in either barren or enriched environments from birth to 14 weeks. The barren environments were defined as intensive housing and...

Mixing at young ages reduces fighting in unacquainted domestic pigs

We found no significant relationship between age and the likelihood that a pair of piglets would fight during the first 75 min after mixing. However, the duration of the first fight observed increased from 101?38 s at 5 days to...

Hoop housing for feeder pigs offers a welfare-friendly environment compared to a nonbedded confinement system

Group-housed pigs kept in an enriched environment, i.e., bedding performed fewer abnormal behaviors, had lower plasma cortisol concentrations in response to stress [handling], had a greater rate of play behaviour, and fewer leg injuries than pigs kept in a barren,...

Effects of different degrees of social isolation on the behaviour of weaned piglets kept for experimental purposes

The effect of degree of isolation on the behaviour of weaned piglets was investigated using eight replicates of littermates, weaned at 4 weeks and caged for 2 weeks in metabolism chambers under varying degrees of isolation: i) fully isolated without...
