Uso de complexo enzimático em dietas para frangos de corte

Abstract

To evaluate the effects of providing nutritional diets containing different levels associated with a multienzyme complex on the performance characteristics of the ash and blood parameters at various stages in the diet of broiler chicks was used to cut 900. The trial was conducted in a completely randomized design arranged in a 3X2 factorial, with three levels and two levels of dietary inclusion of MC. For the pre - initial no significant interaction between nutrient levels and the addition of the multienzyme complex for the parameters evaluated. However significant differences in the nutritional level factor even happened to the final stage (1 to 41dias). Was no effect of nutritional level and multienzyme complex during 1-20 days for the variables weight gain and feed conversion, feed intake variable to no interaction between the factors, but there was a significant difference in the factor MC. In phase 20-41 days there were significant differences between factors for weight gain, feed intake and feed conversion while it was not significant. To ashes and blood parameters there was no interaction between the factors, except for phosphorus in blood parameters. We conclude that the use of multienzyme complex did not benefit the performance of broiler, although it provided satisfactory values of calcium and phosphorus in birds 20 days and calcium in birds at 41 days of age. The multienzyme complex did not improve bone mineralization of the femur.
