Abstract
The effect of corn distillers dried grains with solubles (DDGS), used in grower-finisher diets with or without supplemental enzymes, on growth performance and carcass and meat quality was determined in an experiment with 48 pigs. Group I (control) received a standard grain-soybean meal mixture without DDGS and without enzymes; Group II was fed a mixture containing 15% (grower) or 20% (finisher) of corn DDGS but without the enzymes; Group III received a mixture containing 15% (grower) or 20% (finisher) of corn DDGS with NSP-hydrolyzing enzymes (200 g t-1). The feed mixtures were isonitrogenous and isoenergetic. All pigs were fattened from 30 to 112 kg. At the end of the experiment all pigs were slaughtered, right carcass sides were evaluated and samples of longissimus muscle were taken for analysis. Inclusion of corn DDGS did not significantly affect pig fattening results and meat quality. The addition of NSP-hydrolyzing enzymes to feed mixtures containing corn DDGS tended to positively influence pig performance. The carcasses of pigs receiving the diet with corn DDGS and NSP-hydrolyzing enzymes were characterized by thinner backfat and greater weight of the primal cuts.
