Abstract

This work aim to analysis the effects caused by the utilization of two enzymatic complexes, Allzyme SSF e Allzyme Vegpro, (Alltech®), in the performance of broilers of 1 to 42 days of age. Further, it pretends evaluate economically the availability of this complexes. The design adopted will be randomized complete block and 840 birds will receive 7 treatments with 4 replicates: T1: control - no addition of enzymatic complex ; T2: SSF positive control - addition of Allzyme SSF® considering the recommendation of nutritional value of the enzymatic complex; T3: SSF negative control - no addition of Allzyme SSF® but considering the recommendations of nutritional value of the enzymatic complex Allzyme SSF®; T4: Vegpro positive control - addition of Allzyme Vegpro® considering the recommendation of nutritional value of the enzymatic complex; T5: Vegpro negative control - no addition of Allzyme Vegpro® but considering the recommendation of nutritional value of the enzymatic complex Allzyme Vegpro® ; T6: SSF+Vegpro positive control - addition of Allzyme SSF® and Allzyme Vegpro® considering the recommendation of nutritional value of both enzymatic complexes; T7: SSF+Vegpro negative control - no addition of Allzyme SSF® neither Allzyme Vegpro® but considering the recommendations of nutritional value of both enzymatic complexes Allzyme SSF® and Allzyme Vegpro®. The parameters evaluate for the performance will be: weight gain, feed conversion and feed intake. The cost analysis will consider the chick price, vaccination, feed, medication, couch and fixed price to all the treatments recommended by the Associação Paulista de Avicultura (APA). The variance analysis and Tukey Test will be done at 5% probability.
