Behaviour of pigs and the design of a new housing system

Based on ethological observations of free-ranging pigs, a new housing system was designed incorporating features that allow the animals to express a much wider range of species-typical behavior patterns than in the conventional housing systems. Those species-typical behaviors are described.

Ethological demands in the keeping of pigs

Some requirements for the adequate housing of pigs are discussed. Quantitative production performance can be no criterion as to whether the essential demands of the animals concerning locomotion, resting, comfort and social behaviour are met or not. Production yield can...

Effects of rearing environment on the behavior of young pigs

Pigs raised in an enriched environment with weekly petting were less excitable compared to pigs raised with no extra environmental stimulation. Pigs exposed to an enriched environment approached novel objects more quickly than animals raised in a barren environment. Observation...

Objective measurement of effects of environmental complexity on young pigs

Pigs who were adapted to a complex environment containing different objects approached novel objects and strange people more readily than pigs raised in a unstimulating, standard pen environment.

De-arousal properties of stereotyped behaviour: Evidence from pituitary-adrenal correlates in pigs

It was demonstrated that stereotyped chain pulling was accompanied by decreased levels of pituitary adrenal activity, and it was suggested that stereotypies enable the animals to decrease excessive arousal rather than provide an extra source of stimulation.

The enrichment of a bare environment for animals in confined conditions

New earth and food were given at the same time ... and all piglets in these groups used the earth trough [for rooting] before [emphasis added] feeding.

A comfortable minimum stress method of restraint for Yucatan miniature swine

Slings make a relatively comfortable restraint for pigs. The pressure on the belly seems to have a calming effect. Most Yucatan pigs, regardless of size, can be restrained by one person when using the sling method. When sling-restrained, most Yucatan...

Restraint reduces size of thymus gland and PHA skin swelling in pigs

Pigs were restrained alone in narrow boxes for two hours a day for three days. The animals subsequently showed reduced thymus weights and immune response, and elevated cortisol levels.
