Evaluation of Vomitoxin Control Strategies on Nursery Pig Growth Performance and Blood Measures

A total of 4,318 pigs (337 × 1050, PIC; initially 14.3 ± 0.18 lb) were used in a 35-d growth trial to evaluate mycotoxin control strategies on nursery pig performance and blood measures. Pigs weaned at approximately 21 d age randomly allotted 1 5 dietary treatments. The randomized complete block design was blocking structure including sow farm origin, date entry into the facility, average pen BW. 160 pens with 80 double-sided 5-hole stainless steel fence line feeders, feeder serving as experimental unit. For each feeder, contained 27 gilts barrows. There 16 replications per treatment. common phase diet fed pelleted form all for 7 prior treatment diets. Experimental treatments single included 1) low deoxynivalenol (DON) diet; 2) high DON 3) + sodium metabisulfite (SMB); 4) Technology1; or 5) Technology1+. Overall (d 0 35), had reduced (P < 0.001) ADG, ADFI, final BW compared diet. Furthermore, DON+SMB greater 0.05) DON, DON+Technology1, DON+Technology1+ An improvement feed efficiency observed diets DON+Technology1 intermediate. removals mortality economic analysis greatest cost, revenue, IOFC other LC-MS/MS dried spots end revealed that increased concentrations Interestingly, while not statistically significant this study, reductions presence concentration important mycotoxins like fumonisin B1, B2, beta-zearalenol, emerging beauvericin—as well trends circulating neutrophil-to-lymphocyte ratio GGT blood—when suggest metabolic processes may be influenced. In summary, our trial, SMB supplementation led performance, but changes associated Technology1+ warrant further investigation.
