Resumo: This study aimed to evaluate the weight gain in cross breed heifers Nelore X Angus, spayed and nonspayed, kept on pasture and confinement. The animals were allotted in two groups as follows: group 1 consisted of 30 nonspayed heifers with 18 months old. Group 2 was composed of 30 spayed heifers with 18 months old. The animals were allotted in pasture of Brachiaria decumbens and weighted at 39 and 75 days. Significant difference was observed between the average daily gain of the two groups – G1 and G2 (75th day), respectively (0.51 kg and 0.65 kg; P < 0.01). The following day (76th day), all animals were allotted and kept on confinement during 144 days. Significant difference was observed between the average daily gain of the two groups – G1 and G2 (144th day), respectively (0.73 kg and 0.58 kg; P < 0.01). The results of this experiment show that spayed heifers presented a higher daily gain on pasture.

Esse estudo teve o objetivo de avaliar o ganho de peso em novilhas mestiças Nelore x Angus, castradas e não castradas, mantidas em pastagem e confinamento. Os animais foram alocados em dois grupos assim constituídos: grupo 1 formado por 30 novilhas não castradas com 18 meses de idade. Grupo 2 composto por 30 novilhas castradas com 18 meses de idade. Os animais foram mantidos em pastagem de Brachiaria decumbens e pesados aos 39 e 75 dias. Diferença significativa foi observada entre o ganho médio diário dos dois grupos – G1 e G2 (75ºdia), respectivamente (0,51 kg e 0,65 kg; P < 0,01). No dia seguinte (76ºdia), todos os animais foram transferidos e mantidos por 144 dias no confinamento. Diferença significativa foi observada entre o ganho médio diário dos dois grupos – G1 e G2 (144ºdia), respectivamente (0,73 kg e 0,58 kg; P < 0,01). Os resultados desse experimento mostraram que novilhas castradas apresentaram um maior ganho diário em pastagem.UEL2007-10-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/344410.5433/1679-0359.2007v28n2p317Semina: Ciências Agrárias; Vol. 28 No. 2 (2007); 317-322Semina: Ciências Agrárias; v. 28 n. 2 (2007); 317-3221679-03591676-546Xreponame:Semina.
