Abstract

SOUZA, Cicília Maria Silva de et al. Characteristics of carcass and non-carcass components of Canindé goats under supplementation and grazing in the caatinga. Rev. bras. saúde prod. anim. [online]. 2015, vol.16, n.3, pp.723-735. ISSN 1519-9940.  http://dx.doi.org/10.1590/S1519-99402015000300022.

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.
