Alimentação alternativa de frangos tipo colonial com resíduo agroindustrial de fruta

Abstract

The purpose of this study the effect of using flour residue from the manufacture of acerola juice was to evaluate (Malpighia punicifolia) on productive performance, on carcasses and meat characteristics and on the digestive system of pasture raised broiler chickens (Label Rouge). A total 150 males and females birds were distributed in a completely randomized design with three treatments (0, 10 and 20% acerola meal) and five replicates. The productive performance was assessed by weighing the feed and poultry. After 87 days the birds were slaughtered and their intestinal measured portions and certain the carcass yield and its composition: the percentage of the main cuts of meat, the viscera and abdominal fat. Later carcasses were sampled and analyzed for texture, color and breast samples were collected for sensory analysis. The results demonstrate that the inclusion of 10% flour acerola to the diet of the birds did not alter the performance parameters, but there was a decrease in carcass yield of birds that consumed the product, tested in two levels of supplementation. The biometric evaluation demonstrated that the use of acerola flour duodenum stimulated the development of the poultry, and consequently, the total length of the intestine. The addition of the acerola flour in the diet of the birds did not affect the color, texture, flavor and appearance of meat. Therefore, despite some negative effects associated with supplementation of acerola meal in the diet of birds, this work can contribute to extend the vision of the producers and suggest alternatives for the production of chicken meat colonial type
