Resumo: | Estimates of genetic parameters are important to study characteristics that are to be included in a breeding program of a genetic group. The information of 594 weights from 211 lambs of a genetic group of naturalized Sul-mato-grossenses sheep belonging to Manoel de Barros Foundation and breeding at Centro Tecnologico de Ovinos from Anhanguera-Uniderp University was used. The estimation of variance components in unicaracter and bicaracter analysis were carried out through Bayesian inference. Estimates of heritability ranged from unicaracter analyses (0.22 to 0.47) and the bicaracter analyses (0.13 to 0.78). The maternal environmental permanent effect was higher in birth weight and average daily gain from birth to 50 days in 24.2% and 19.5%, respectively, in the observed variation. Estimates of heritability, maternal environmental permanent effect participation, phenotypic and genetic correlations indicate that selection for average daily gain from birth to 90 days would imply increases in weight at 50 days, weight at 90 days and average daily gain from 50 to 90 days of lambs with no significant increase in birth weight and average daily gain birth at 50 days. |

Foram utilizadas 594 informações de pesos referentes a 211 cordeiros do grupo genético de ovinos naturalizados Sul-mato-grossenses pertencentes à Fundação Manoel de Barros, criadas no Centro Tecnológico de Ovinos (CTO) da Universidade Anhanguera-Uniderp localizado em Campo Grande-MS. A estimativa dos componentes de variância nas análises uni e bicaracter foi realizada por meio de inferência bayesiana. As estimativas de herdabilidades unicaracter variaram de 0,22 a 0,47 e bicaracter de 0,13 a 0,78. O efeito permanente de ambiente materno foi maior no peso ao nascimento (PN) e no ganho de peso do nascimento aos 50 dias (GP0-50) em 24,2% e 19,5%, respectivamente, da variação observada. As estimativas de herdabilidades, participação do efeito permanente de ambiente materno, correlações genéticas e fenotípicas indicaram que a seleção para ganho de peso do nascimento aos 90 dias implicaria em incrementos no peso aos 50 dias, peso aos 90 dias e ganho de peso dos 50 aos 90 dias (GP50-90) dos cordeiros com aumentos inexpressivos no PN e GP0-50.UEL2014-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1242410.5433/1679-0359.2014v35n2p963Semina: Ciências Agrárias; Vol. 35 No. 2 (2014); 963-972Semina: Ciências Agrárias; v. 35 n. 2 (2014); 963-9721679-03591676-546Xreponame:Semina.
