The objective of the research to verify the feasibility of using an enzyme complex for pigs in the nursery phase, by evaluating the performance and digestibility of diets containing two types of carbohydrates with or without addition of enzyme complex containing carbohydrases, proteases and phytase . There were two experiments were conducted in the Department of Poultry Department of Animal Production, School of Veterinary UFG. In the first experiment was to evaluate the digestibility of the nutrients with the use of twelve animal hybrids, the genetic line Dalland barrow. The design was randomized blocks in time, with four treatments (T1: maize and soybean meal without the EC, T2: low tannin sorghum and soybean meal without the EC, T3: corn and soybean meal with CE, T4: low tannin sorghum and soybean meal with CE) and six replicates using a 2x2 factorial design, with them, carbohydrate and enzyme. The digestibility of experimental diets were formulated to isonutrient digestible amino acids. In Experiment II were weight gain, feed intake and feed conversion, besides the economic viability analysis of the diets to be tested. A total of 48 animals, 24 barrows and 24 females. The treatments were the same used in the metabolism trial, but T2 and T4 were formulated with lower levels of MS (-50 Kcal / kg) Ca (- 0.1%) and P (- 0.1%). The results were subjected to analysis of variance (ANOVA) and comparison of means by Tukey test (5%). For the digestibility experiment were not significant differences (P> 0.05) for the variables shown in any of the stages studied, except for calcium (P <0.05) which was absorbed in greater proportion with the addition of the enzyme. For the performance trial, according to analysis of variance no significant differences were observed in relation to food source of variation for the following variables PI, and CRT and CRD source of variation for enzyme parameters PI, PF, GPD, GPT did not suffer significant differences. As the interaction of food and enzyme differences were observed only for PF, and GPT and GPD CA. It was concluded that the substitution of corn by sorghum and the inclusion of the enzyme complex is feasible on the growth performance
