In order to assess chronic stress in entire and castrated male pigs and to describe effects of a provision of grass silage in those pigs, a 2 × 2 × 2 factorial experiment comprising the factors castration, chronic intermittent social stress and provision of grass silage was carried out with 147 growing-finishing pigs from 25.6 to 102.1 kg body weight. The experimental design allowed investigating interactions between the three factors, but only few were statistically significant. Stress exposure consisted of repeated short-term confrontations with unfamiliar pigs and short-term separations. Carcasses of stress-exposed pigs had thicker backfat, lower lean meat percentage and a different fatty acids composition of the adipose tissue. While entire males... |

Physiological and behavioural reactions of cattle to handling procedures in a commercial abattoir (electrical prodding actions and duration of the animals׳ stay in the stunning box) were evaluated and set in relation to sex, breed type, and carcass weight. A total of 192 cattle comprised of 45 bulls, 61 steers, and 86 heifers from different breed types (30 dairy breed, 70 beef breed, and 92 crossbreds) were observed from lairage to slaughter during one day. The frequency of electrical proddings and the waiting time in the stunning box was recorded for each individual. As a measure of a behavioural stress response, the number of vocalising animals was recorded. Exsanguination blood serum samples were analysed for cortisol, glucose, and lactate... |

In artificial rearing, calves are separated from their dam usually within 24h after birth and any further social contacts to the mother are prevented. Although this is common in practice we expect severe consequences on the health state, weight gain and stress response of the young calf. Two groups of calves suckled by their mother (unrestricted contact, n=14; contact twice daily for 15 minutes each before milking, n=15) were compared to two control groups that were both fed via automatic milk feeder (maximal six times daily, n=14; twice daily, n=14). The calves of the four treatment groups were kept in the same barn and cows were milked twice daily. All calves were weaned at 13 weeks of age. The calves were weighed weekly until 3 weeks after... |
