Resumo: Data from 629 meat type quails were used to study association between two different sets of traits: egg production and reproduction. Traits related to reproduction were: body weight at 42 days (W42), average egg weight (AEW), age at sexual maturity (ASM); and production traits: number of eggs produced from 42 until 182th day considering intervals of 35 days each period (P1, P2, P3 and P4). Canonical correlations were used to describe the association between these two sets of traits. The canonical coefficients indicated that egg production and reproductive traits were moderately related (0.3475). The first partial period of production (P1) and age at sexual maturity were the most relevant traits among the analyzed variables. Results show that selecting animals with lower age at sexual maturity might lead to an increase on number of eggs produced until 77 days, although it might also lead to a decrease on egg weight. Breeding programs aiming to improve quails production should consider selection strategies to decrease age at sexual maturity and then, as correlated response, increased egg production might be observed.

As características analisadas foram: peso corporal aos 42 dias (W42), peso médio de ovos (AEW) e idade à maturidade sexual (ASM), que compôs as características reprodutivas; e números de ovos produzidos a partir do 42o dia, divididos em intervalos de 35 dias cada (P1, P2, P3 e P4), que integrou o grupo de características de produção. Para análise de associação, foi utilizada a análise de correlação canônica entre os dois conjuntos de características. Os coeficientes canônicos indicaram que os conjuntos de características de produção de ovos e reprodutivas são dependentes, correlacionando-se moderadamente (0,3475). Entre as variáveis avaliadas, o primeiro período parcial de produção de ovos e a idade à maturidade sexual foram as mais importantes. Os resultados indicam que a seleção para menor idade à maturidade sexual resultaria em aumento no número de ovos produzidos até 77 dias de idade, embora essa seleção possa resultar em diminuição do peso de ovo. Conclui-se que a seleção de aves deve ser efetuada para menor maturidade sexual, pois, assim, estará selecionando também aves para maior produção de ovos.Ciência Rural2019-04-26T18:04:00Z2019-04-26T18:04:00Z2016-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1678-4596http://dx.doi.org/10.1590/0103-8478cr20150215http://www.locus.ufv.br/handle/123456789/24823engv. 46, n. 7. p. 1289- 1294, jul. 2016Ribeiro, Jeferson CorrêaSilva, Luciano Pinheiro daCaetano, Giovani da CostaCrispim, Aline CamporezPacheco, Rodrigo de OliveiraTorres, Robledo de Almeidainfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T08:33:14Zoai:locus.ufv.br:123456789/24823Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T08:33:14LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
