Characteristics of carcass and non-carcass components of Canindé goats under supplementation and grazing in the caatinga

Abstract

The aim of this study was to evaluate the effect of concentrate supplementation on weight gain, the quantitative characteristics of carcass and non-carcass components of the castrated goat carcass Canindé breed grazing system in the native pasture caatinga. 40 goats with an average body (BW) initial weight of 15.76  0.96kg were distributed in a completely randomized design in levels of 0; 0.5; 1 and 1.5% of supplementation (% BW) and were slaughtered when the animals from the 1.5% of supplementation level reached 23.101.74kg. Performance, carcass yield, yield of cuts and weight of non-carcass components (skin, head, blood, liver, kidneys, respiratory tract, gastrointestinal tract) as well as total fat weightwere positively influenced by supplementation levels. The supplementation levels of 1 and 1.5% of body weight are favorable to performance and quantitative characteristics of Canindé goat kids grazing in the native pasture caatinga.
