| Entire male pigs display more aggressive and sexual behaviour. This might cause a condition of chronic stress and impair their welfare. In order to assess chronic stress in entire and castrated male pigs, as well as effects of providing grass silage as occupational and feed material on behaviour and health, we carried out a 2 × 2 × 2-factorial experiment with 147 growing-finishing pigs. Factors investigated were castration (entire/castrated), chronic intermittent social stress exposure (yes/no) and access to grass silage (yes/no), as well as their interactions. The stress exposure treatment consisted of repeated short-term confrontations and separations. We recorded different behavioural variables, circadian rhythm of salivary cortisol, response to an ACTH... |

| Fusarium head blight and the contamination of cereals with the Fusarium toxins deoxynivalenol (DON) and zearalenone is more prevalent when fields are not tilled in order to conserve the soil structure. DON impairs the feed intake and the growth rate of young pigs, whereas both, DON and zearalenone affect the fertility of sows. In two feeding trials using a total of 220 weaner pigs the hypothesis was tested that apple pomace alleviates the negative effects of Fusarium toxins. The two experiments had a 2 x 2 factorial design: Fusarium contaminated and uncontaminated wheat, and 8 % apple pomace and no pomace in the diet. In both trials, the animals receiving the mycotoxin contaminated diets without pomace gained less weight than the pigs receiving either... |

| In organic and other enriched housing systems, straw is commonly used as enrichment material for pigs. Its positive effects on health and behavioural welfare are well known. However, potential additional impacts of roughages (other than straw) have rarely been investigated. On six organic farms, we therefore investigated how providing grass silage affects behaviour, gastric health and performance of growing-finishing pigs. Per farm, two to four pens were included in the experiment, with group sizes ranging from five to 26 pigs (total n = 368), and stocking density ranging from 1.65 to 3.50 m2 per pig during finishing. Groups were provided with either grass silage (SIL) or straw (CON) in a rack. Long-stack straw was used as bedding material in all pens.... |
