Can Bovine Plasma Mitigate the Impact of DON?

219

Deoxynivalenol (DON) is a concern to swine producers as it may cause production related issues specifically related to reduced feed intake, growth and health problems. Spray-dried porcine plasma (SDPP) has been shown to mitigate the effects of DON. This study aimed to determine the effect of DON and spray-dried bovine plasma (SBBP) inclusion in the diet on feed intake, growth performance and gut health in newly-weaned pigs. Seventy-two nursery pigs were divided into six treatment (trt) groups :1) Diet A (no DON or SDBP), full-fed, 2) Diet B (with DON no SDBP), full-fed, 3) Diet A, limit-fed, 4) Diet C (no DON with SDBP), fullfed, 5) Diet D (with both DON and SDBP), full fed, and 6) Diet C, limit fed. No significant difference in average daily gain (ADG), body weight (BW) or feed efficiency (FI) were found between the control diet (treatment1) and DON (treatment2) or SDBP diet (treatment4), indicating that DON and SDBP had no detrimental or beneficial effect on performance of nursery pigs, respectively.

Moreover, there was no significant difference among the treatment groups for gut morphology, indicating no harmful effects on gut health. However, there was a significant decrease in ADG and BW for treatment (DON and SDBP) when compared to treatment (no DON or SDBP). No differences were

found between the full fed and the pair-fed (limit fed) group, indicating that the effects of DON and SDBP were not due to feed intake. Further research is needed to better understand the effect of DON and SDBP inclusion in diets on growth performance of pigs.
