Resumo: The objective of this two-year study was to determine the effect on the reproductive and productive performance of a concentrated feed composed of maize and cotton seed on the last period of pregnancy (45 days) and the first period of lactation (45 days) to 58 woolless ewes without definite breed (SRD) In the first and 62 in the second year. The animals were divided into two groups, T1 and T2. The check-group T2 was mantained only on native pasture. No differences were observed between the two groups, which presented high rates of performance. The fertility rate was 100% in the first year and 100,0% (T1), and 93.5% (T2) in the second. The mean of the weight at birth was 2.8 kg and 16.3 kg at winning. Considering the weight at birth, a significant effect of P<0.05 was observed between the years. The first oestrum occurred 63.0 days after parturition. The different food supply used in this experiment did not affect the reproductive and productive performance of the ewes.

Os animais, 58 no primeiro ano e 62 no segundo, foram divididos em dois grupos iguais (T1 e T2), sendo o grupo T2, o grupo testemunha, mantido em pastagem nativa. Não houve diferença entre os tratamentos em nenhum dos grupos nos quais as taxas dos parâmetros estudados foram altas. A taxa de fertilidade foi de 100% no primeiro ano, em ambos os grupos, e de 100,0% e 93,5% no segundo ano, nos grupos um e dois, respectivamente. A média do peso ao nascer, nos dois grupos, foi de 2,8kg e de 16,3 kg ao desmame. Houve um efeito significativo (P<0,05) do ano, tipo de parto e sexo sobre a média do peso ao nascer. O intervalo médio do primeiro estro pós-parto foi de 63,0 dias, em ambos os grupos. A suplementação estudada não alterou o desempenho produtivo e reprodutivo, quando comparada aos ovinos tratados somente na pastagem nativa.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Antonio Emidio Dias FelicianoUnanian, Maria MarinaBarros, Nelson Nogueira2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15015Pesquisa Agropecuaria Brasileira; v.21, n.9, set. 1986; 987-997Pesquisa Agropecuária Brasileira; v.21, n.9, set. 1986; 987-9971678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15015/8732info:eu-repo/semantics/openAccess2014-10-30T16:23:59Zoai:ojs.seer.sct.embrapa.br:article/15015Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-30T16:23:59Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
