Utilização de Coproduto da Goiaba Desidratada e Complexo Enzimático na Alimentação de Frangos de Corte.

Abstract

It was evaluated the dehydrated guava co-product use as a partial replacement for corn, with or without an enzyme complex in the broiler chickens feeding. It was used 360 Ross lineage chicks, one day old, initial weight average ±37g between males and females, distributed in 36 boxes. The experimental design was entirely randomized in a 3x2 factorial scheme (0, 5 and 10% of guava co-product, with or without enzyme complex), totaling six treatments and six replications of 10 birds per experimental unit, as it follows: Control: feed reference, based on corn bran and soybean; Inclusion of 5% guava co-product replacing corn; Insertion of 10% guava co-product replacing corn; Reference feed, based on corn bran and soybean with enzymatic complex; Inclusion of 5% guava co-product replacing corn with enzymatic complex addition; Inclusion of 10% guava co-product replacing corn with enzymatic complex addition. The water supply and feed was ad libitum during all the experimental period and it was computed the feed consumption, the bird average weight and mortality for the productive performance calculation and economic viability. At 42 days of age, the birds were slaughtered and subsequently it was evaluated the performance, carcass yield, cuts and organs, meat quality parameters (color, pH, weight loss due to cooking and dripping, shear force) and morphometric evaluation from the intestine parts. The CGD inclusion levels with addition of enzymatic complex influenced (P<0,05) improved feed conversion (1-21; 1-42 days), reduced liver weight and increased the abdominal fat weight, reduced the breast yield, into the quality parameters improved the shear strength and CGD inclusion influenced (P<0,05) in the skin and meat color. There was no significant effect of CGD inclusion with enzyme complex addition on the variables from weight gain and feed consumption. Suggesting the inclusion 5% CGD with the enzymatic complex addition in partial replacement from corn on broiler chickens diets from Ross lineage, without prejudicing the performance, carcass yield, meat quality parameters.
