FONTES DE FIBRA SOLÚVEL E INSOLÚVEL SOBRE CARACTERÍSTICAS DE CARCAÇA E QUALIDADE DE CARNE DE FRANGOS DE CRESCIMENTO LENTO

Abstract

Bird breeding in alternative systems comes around during the main the years that are, technologies that foment this activity must be developed. Thus, the objective was to verify the effects of dietary inclusion of soluble fiber sources and insoluble (citrus pulp and corn cob, respectively) on the characteristics of carcass and the quality of the meat of slow-growing chickens. The experimental design It was completely randomized (DIC) in a 2 x 2 + 1 factorial scheme with 8 replications of 10 birds Each one to an early stage. remaining with 40 birds / treatment until the 80 days of age. In the initial stage of creation as birds were raised in metabolic cages and from 35 days onwards, the chickens were housed First floor of 23.8 m2 with pasture area of ​​208 m2. At 80 days of age the birds were slaughtered and after the carcass yield, yield of noble cuts, breast morphometry, color, weight loss by cooking and thawing. The inclusion of Citrus pulp resulted in higher yield of thigh and breast length and lower fat in relation to corn cob. The supply of fiber sources in the initial diet, does not alter live weight, carcass yield and results in stiffer and yellowish flesh, Therefore, it may be a recommended nutritional strategy to contribute to the differentiation of slow-growing poultry meat.
