COMPLEJOS ENZIMÁTICOS COMO SUPLEMENTO EN LA ALIMENTACIÓN DE POLLOS DE ENGORDE

Abstract

ABSTRACT The high speed of passage of food in birds is one of the determining causes of the low digestibility of the food. However, the use of enzymes has made it possible to improve the use of the food. In order to determine the effect of two commercial enzymatic complexes [Ronozyme VP® (R-VP) and Avizyme 1500® (A-1500)] on the productive performance of broilers, during the initial phase (1 - 21 days) and the final phase (22-49 days) of chickens, using a completely random design with three treatments and six repetitions (30 chickens per repetition), three treatments were tested: food without enzyme (T1), food + 30 mg R-VP kg^-1 (T2) and food + 30 mg A-1500 kg^-1 (T3). For the comparison of means, the Tukey test was used at 5% probability. There were no differences in feed intake in the initial phase and in the final phase, with 0.918 and 4.483 kg chicken^-1, respectively. The differences were observed only in the initial phase, in the weight increase (PI) and in the feed conversion (CA), with T1 standing out with 0.646 kg chicken^-1 and 1.428 kg kg^-1, respectively. The results indicate that the use of an enzyme complex (R-VP) does not affect the consumption of food, but if it improves the feed conversion during the initial phase of the broilers, for which the use of enzymes is recommended during the first 21 days of age of the chickens.
