Farelo de soja fermentado em rações para frangos de corte.

Abstract

The present study aimed to evaluate the use of fermented soybean meal (FSF) in productive performance, nutrient metabolizability and intestinal morphometry of broilers. The commercial product used was PepSoyGen® (Nutraferma). In the performance test, 960 1-day-old chicks were used in 40 boxes, 12 males and 12 females per box, in a completely randomized design, arranged in eight replications of five treatments: T1 - control without the addition of PepSoyGen®; T2 - addition of 0.5% PepSoyGen®; T3 - addition of 1.0% PepSoyGen®; T4: addition of 1.5% PepSoyGen®; T5 - addition of 2.0% PepSoyGen®. For the metabolizability test, a total of 400 14-day-old male broiler chicks were used, distributed in a completely randomized manner in 40 metabolic cages. The experiment consisted of the same five treatments, with eight replicates and 10 birds/repeat (cage). No effect of inclusion levels was observed for performance variables and intestinal morphometry at the end of the first experiment. For metabolizability, there was also no effect of the product inclusion levels. It was concluded that fermented soybean meal (PepSoyGen®) in diets for broilers did not affect productive performance, carcass yield and characteristics, relative organ weight, nutritional metabolizability and intestinal tract morphometry.
