Desempenho e característica de carcaça de cabritos superprecoce alimentados com dietas a base de feno de capim-buffel ou silagem de sorgo forrageiro

Abstract

The objective was to evaluate the performance and carcass characteristics of super early goat kids diets containing buffel grass hay or sorghum silage. Sixteen male goats, integers, of the Anglo-Nubian breed, with a mean initial weight of 9.02 ± 1.24 kg, with a mean age of 50 days were used. The experimental design used was completely randomized, with two treatments and eight replications. The diets were composed with a high proportion of concentrate, evaluating two types of forage, buffel grass hay and sorghum silage, the treatments used were: T1: 30% buffel grass hay and T2: 30% sorghum silage . Performance, carcass yield, morphometric evaluation, weight and yield of cuts and pH of the leg muscle were evaluated. There was no significant difference (P>0.05) for any of the variables evaluated. Thus, the choice of roughage source for the confinement of super-early goats will depend on the availability and production cost of buffel grass hay or sorghum silage.
