Einfluss von mykotoxinbelastetem Streustroh auf die Fruchtbarkeit von ZuchtsauenAndreasGutzwillerauthorJean-LouisGafnerauthorThe 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, and its use is to be encouraged to improve animal welfare.
