Interpretive Summary:

Technical Abstract: A growth performance (Exp. 1) and a digestibility (Exp. 2) experiment were conducted to determine the efficacy of an enzyme preparation, Allzyme Vegpro, in diets for nursery pigs containing soybean meal (SM; 44% CP) or dehulled SM (DSM; 47% CP). Vegpro contains protease, cellulase, pentosanase, alpha-galactosidase, and amylase activity. Pigs (n = 200) were eweaned at about 19 d of age for Exp. 1. After consuming a common phase 1 diet for 12 d, pigs were blocked by weight and allotted to 20 pens. Pens were assigned randomly within block to one of four diets in a 2 x 2 factorial arrangement of treatments. Vegpro was included in phase 2 and 3 diets at 0.14 and 0.17%, respectively. Pigs had ad libitum access to phase 2 (1.2% lysine) and 3 (1.1% lysine) diets that were marginal in lysine concentration for 2 and 3 wk, respectively. Pigs fed DSM grew faster (P < 0.05) than those fed SM regardless of Vegpro inclusion (0.529 vs 0.475 kg/d). An interaction (P < 0.01) between Vegpro addition and SM type was observed for feed efficiency (1.724, 1.774, 1.692, 1.608 for -V/SM, +V/SM, -V/DSM, and +V/DSM, respectively). In Exp. 2, barrows (n = 20) were weaned at about 18 d and housed individually in stainless steel cages. Pigs received a common phase 1 diet for 14 d then were assigned randomly within litter to the same phase 2 diets as used in Exp. 1. A 7-d adjustment period preceded a 5-d total collection period to determine energy and nitrogen balance. Nitrogen retention and ME were not influenced by diet. Addition of Vegpro tended to reduce (P < 0.10) digestibility of total dietary fiber polysaccharide (72.6, 66.9, 70.5, 65.8 %). Addition of Allzyme Vegpro to corn-soybean meal based diets did not improve growth performance of nursery pigs or digestibility of dietary energy or nitrogen.
