| الوصف: | Este experimento objetivou comparar o desempenho e as características de carcaça de 14 cordeiros, sendo quatro da raça Texel, cinco da raça Suffolk e cinco cruza Texel x Suffolk. Os cordeiros foram desmamados aos 64 dias de idade em média, e terminados em regime de confinamento total, até o abate com idade média de 128 dias. Do nascimento ao desmame, as ovelhas (mães dos cordeiros) foram mantidas em pastagem nativa e receberam uma suplementação concentrada na proporção de 1% de peso vivo, tendo também os cordeiros acesso a uma suplementação concentrada na forma de creep-feeding na proporção de 1,5% do peso vivo. O alimento concentrado utilizado na suplementação das ovelhas e dos cordeiros continha 21% de proteína bruta (PB), 70% de nutrientes digestíveis totais (NDT), 2% de cálcio (Ca) e 0,4% de fósforo (P). Após o desmame, os cordeiros passaram a receber uma dieta composta por feno de Tifton-85 (Cynodon dactylon) + concentrado, na proporção 40:60 na Matéria Seca (MS), a qual continha 15,1% de PB, 60,8% de NDT, 1,4% de Ca e 0,3% de P. O peso ao abate foi inferior (PThe objective of this work was to compare the performance and carcass characteristics of 14 lambs, being four of the Texel, five of the Suffolk and five cross Texel x Suffolk breeds. The lambs were weaned at 64 days of age in average, and finished in feedlot, until slaughtering with average age of 128 days. From birth to weaning, dams were maintained in native pasture and received a concentrated supplementation at a 1% ratio of live weight and lambs had access to a concentrated supplementation in the form of creep-feeding at a 1.5% ratio of the live weight. The concentrated food used in the supplementation of the sheep and the lambs contained 21% of crude protein (CP), 70% of total digestible nutrients (TDN), 2% of calcium (Ca) and 0.4% of phosphorus (P). After weaning, lambs started to receive a composed diet of hay made of Tifton-85 (Cynodon dactylon) + concentrate, at a 40:60 ratio in the dry matter (DM), which contained 15.1% of CP, 60.8% of TDN, 1.4% of Ca and 0.3% of P. The slaughter weight was lower (P |
