EFFECTS OF DIETS WITH GRADED-LEVELS OF DEOXYNIVALENOL ON PERFORMANCE IN GROWING PIGS

Feeding trials were conducted to evaluate the effect of including deoxynivalenol (DON)-contaminated oats to provide approximately 0.5, 1.0, 2.0 and 4.0mg/kg in the complete diets of growing pigs with initial weight of 25 kg. Performance was recorded as weight gain, feed intake, efficiency of feed utilization and carcass quality. Restricted feeding was compared to ad libitum feeding. For the groups fed diets containing 2 and 4 mg/kg of DON, a dose-related decrease in weight gain was observed during the first 8 weeks on experimental diets. With 4mg/kg DON there were decreased feed intake, weight gain and efficiency of feed utilization throughout the experiment. No effect was observed in groups fed diets containing 0.5 or 1.0 mg/kg of DON. The carcass quality was not affected in any group.
