Abstract

VOLTOLINI, Tadeu Vinhas; MORAES, Salete Alves de; ARAUJO, Gherman Garcia Leal de  and  PEREIRA, Luiz Gustavo Ribeiro. Concentrate levels for lambs grazing on buffel grass. Rev. Ciênc. Agron. [online]. 2011, vol.42, n.1, pp. 216-222. ISSN 1806-6690.  http://dx.doi.org/10.1590/S1806-66902011000100027.

Use of concentrate for lambs grazing buffel grass may improve animal performance and animal traits. The objective of the present trial was to evaluate the final body weight, average daily gain, total weight gain and carcass traits (cold and hot carcass weights, cold and hot dressing percentages) of lambs grazing buffel grass and receiving different concentrate levels (0; 0.33; 0.66 and 1.0% of dry matter in relation to body weight). Forty lambs were used, ten animals by treatment, with 16.5 ± 2.0 kg of initial body weight, distributed in four groups. Experimental design was a completely randomized with ten replicates. Concentrate levels did not influence the final body weight, the average daily gain, total weight gain and cold and hot carcass weights. However, the increase of concentrate levels promoted higher cold and hot carcass yields.
