| 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... |

| Plants with moderate contents of condensed tannins are assumed to have anthelmintic Plants with moderate contents of condensed tannins are assumed to have anthelmintic properties and to improve protein supply of ruminants by reducing its ruminal degradability. In the present study, birdsfoot trefoil (Lotus corniculatus), chicory (Cychorium intybus) and sainfoin (Onobrychis viciifolia), suitable to be grown in Central Europe, were tested for their suitability as feed for ruminants. Sainfoin proved to be the most promising forage plant since it was very well accepted by the sheep and presented the highest content of utilizable crude protein as determined in vitro. Only few condensed tannins were detected in chicory. Further in vivo studies are required to... |

| The effect of bedding straw contaminated with Fusarium mycotoxins (1.4 mg/kg deoxynivalenol (DON) and 0.9 mg/kg ZON; median values) on the fertility of group housed sows with daily access to pasture was tested using 48 sows kept on contaminated and 48 control sows kept on uncontaminated straw from mating until farrowing. No abortions were observed. The contaminated straw neither influenced the pregnancy rate nor the number and weight of the newborn piglets. DON up to 1.4 mg/kg and ZON up to 0.9 mg/kg in bedding straw seem to have no negative effects in sows having access to roughage such as pasture grass. Straw without signs of deterioration, even if it may be contaminated with Fusarium mycotoxins, is a suitable bedding material for pregnant sows,... |
