Stereotyped behaviour, adjunctive drinking and the feeding periods of tethered sows

The movement of the food trolley causes considerable excitement in the animals, and it is during this period that bar-biting, nose rubbing, and head-weaving occur most rapidly. ... Stereotyped sequences of behaviour may be a means of reducing the arousal...

Social interactions in a group of free-ranging sows

Description of species-typical behavior of free-ranging pigs. No dramatic differences were found between the behaviour of the free-ranging sows and that of the most extensively housed of the indoor groups studied earlier, although great differences were found between free-ranging sows...

The effect of individual and group housing on behavioural and physiological responses related to the welfare of pregnant pigs

These physiological data indicate a chronic stress response and a significant metabolic cost resulting from housing pigs in tethers. Single-housed pigs showed statistically greater amounts of oral-nasal behaviours (manipulation of drinkers, licking/biting pen components) than group-housed pigs.

Effects of confinement upon behavioural and hormonal responses and production indices in fattening pigs

The provision of straw to intensively housed pigs avoids the chronic elevations in plasma cortisol levels and the reduced growth rate seen in crowded pigs without straw.

Mating behavior, boar-to-boar behavior during rearing, and soundness of boars penned individually or in groups from 6 to 27 weeks of age

Of practical importance, our study indicates that individual penning of young boars to obtain individual estimates of feed conversion would likely have detrimental effects on soundness.

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.

The influence of handling by humans on the behaviour, reproduction and corticosteroids of male and female pigs

Animals who are fearful of humans show a marked increase in corticosteroid levels both in the presence and in the absence of people. Unpleasant handling treatment resulted in a chronic stress response, with consequent adverse effects on reproduction.

Effects of social environment on welfare status and sexual behaviour of female pigs: Effects of space allowance

This study examined the effects of housing groups of adult female pigs (6 pigs per group) with a space allowance of 1, 2 or 3 sq.m per pig. .. There was a significant increase in plasma free-corticosteroid concentrations when gilts...
