Abstract A total of 900 mixed sex pigs (PIC 1050 × PIC 800, ∼ 21 d of age; initial BW of 6.7 ± 0.29 kg) were used in a 42-d growth study to evaluate the effects of feeding increasing levels of a proprietary preservative and flow-agent blend (Abolish 3.0, Kalmbach Nutritional Services; Upper Sandusky, OH) in diets containing deoxynivalenol (DON) contaminated distillers dried grains with solubles (DDGS). Pigs were stratified by initial BW and sex and housed at 10 pigs per pen (5 gilts and 5 barrows). Pens were blocked by location and randomly allotted to 1 of 5 dietary treatments in a randomized complete block design, resulting in a total of 18 replicates. Experimental diets containing high DON contaminated DDGS were fed in 2 phases (d 7-21 and 21-35) while a common diet absent of contaminated DDGS was fed preceding and concluding the experimental diets (d 0-7 and d 35-42, respectively). All diets were corn-soybean meal based and were formulated to meet or exceed the NRC (2012) requirement estimates. The DON contaminated DDGS used in experimental diets were analyzed to contain 30 mg/kg of DON and were added to a basal diet at an inclusion of 15% to target dietary treatments containing 4.5 mg/kg of DON. The dietary treatments consisted of the DON contaminated basal diet with either 0, 0.25, 0.50, 0.75, and 1.0% inclusion of Abolish. Data were analyzed by ANOVA using the MIXED procedure of SAS with the pen serving as the experimental unit and location of block serving as a random effect. Orthogonal polynomial contrasts were used to determine linear and quadratic effects of increasing Abolish inclusion. During the experimental diet period (d 7-35), increasing Abolish inclusion resulted in a linear and quadratic increase in ADG, ADFI, and G:F (P 0.001). The improvements in growth performance observed with feeding increasing doses of Abolish resulted in ∼28% increase in d 35 BW for pigs receiving the 1.0% inclusion compared to the 0% inclusion (20.4 vs. 16.0 kg respectively). Subsequently, when a common diet absent of DON contaminated DDGS was fed (d 35-42), a compensatory linear and quadratic decrease in G:F (P 0.01) was observed with increasing levels of Abolish, where the 0% inclusion had a 12.5% higher G:F compared to the 1.0% treatment. Overall (d 0-42), a linear and quadratic increase in ADG, ADFI, G:F and final BW was observed with increasing Abolish inclusion (P 0.001). Feeding increasing levels of Abolish at doses up to 1.0% of total diet in the presence of DON contaminated DDGS resulted in improved growth performance and ultimately a 4.7 kg advantage in final BW over pigs fed no Abolish.
