| 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.

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.
