Efeitos genéticos aditivos e não-aditivos para características produtivas e reprodutivas em vacas mestiças Holandês × Gir

Abstract: RESUMO -A partir de registros de genealogia e controle leiteiro e reprodutivo fornecidos pela Associação Brasileira dos Criadores de Girolando, foram estimados os efeitos de diferença genética aditiva entres as raças Holandesa e Gir, de dominância e de recombinação, além das herdabilidades e repetibilidades, para as características produção de leite por lactação (PL), produção de leite até os 305 dias de lactação (PL305), duração da lactação (DL), intervalo de partos (IDP), idade ao primeiro parto (IPP) e prod… Show more

“…The heritability estimates for FCI (0.13 to 0.14) were not affected by the inclusion of short lactations; however, it showed slight superiority when model b was used. The values obtained in the present study were superior to those obtained by Val et al (2004), which were 0.10 for the Holstein breed; and Facó et al (2008), which were 0.05 for the Girolando breed, but inferior to the value obtained by Bertipaglia et al (2007) with Holstein cows (0.19).…”

“…Additive variance and heritability estimates for the ICC in this study are similar to those referred to the Asturiana de los Valles breed (8) , in different crosses of B. indicus x B. taurus (17) and Chianina (14) . However, the estimates are superior to others reported in Cuban Zebu cattle (9) and in Santa Gertrudis (27), and also for Girolando cattle (28) and Zebu of Colombia (29) . An estimated high heritability for the CI (0.42) was reported in Brazil Nellore cows (30) .…”

“…Sin embargo, los estimados son superiores a otros reportados en ganado Cebú Cubano (9) y en Santa Gertrudis (27) . Resulta mayor también a los estimados que se reportan en ganado Girolando (28) y Cebú de Colombia (29) . Un estimado de heredabilidad alto para el IP (0.42) fue reportado en vacas Nellore de Brasil (30) .…”

“…Pela classificação de Köppen o clima predominante é o de inverno seco e verão chuvoso com precipitação pluviométrica anual média de 1.365 mm. Apresenta vegetação abundante de matas de babaçu e carnaúba (IBGE, 2010). Foram realizadas algumas restrições no banco de dados para adequar possíveis distorções existentes.…”
