Interpretive Summary: Effect of long-term feeding of graded levels of deoxynivalenol on growth performance, nutrient utilization, and organ health in finishing pigs

Interpretive Summary: Effect of long-term feeding of graded levels of deoxynivalenol on growth performance, nutrient utilization, and organ health in finishing pigs

By Anne Zinn

Deoxynivalenol is one of the most significant mycotoxins in agriculture due to its contamination of common feed grains, and the prevalence of deoxynivalenol is a concern for swine producers. Based on previous research, there is evidence that deoxynivalenol consumption results in reduced feed intake, digestive dysfunction, immune suppression, and reduced growth performance , as research in pigs specifically shows that Deoxynivalenol ingestion causes a reduction in average daily feed intake and body weight gain. Although there has been extensive research on the effects of deoxynivalenol in pigs, there has been little focus on the effects in young pigs. A research study recently published in the Journal of Animal Science aimed to determine the effect of long-term exposure of finishing pigs to deoxynivalenol-contaminated diets on growth performance, nutrient utilization, organ health, and deoxynivalenol content in biological samples.

Results demonstrated that, initially, there was a reduction in average daily feed intake and average daily gain upcon introduction of diets containing deoxynivalenol, but performance recovered after 28 days, suggesting that pigs may be able to adapt to consumption of deoxynivalenol-contaminated diets. Additionally, the lack of negative effect of deoxynivalenol intake on gain to feed ratio suggested that the effect of deoxynivalenol intake on average daily gain is largely due to the reductions in feed intake.
