Resumo: This research evaluates whether the selection for feed-to-gain ratio (FGR) and weight gain (WG), based on individual and/or collective performance of rabbits, can lead to genetic gain in collectively-raised rabbit progenies. Animals were submitted to an evaluation period at the age of 50 to 70 days, using Bayesian inference. Six two-trait analyses were done. Performance testing observed WG and FC traits in both environments. Heritability values ranged from 0.42 to 0.60. Both the genetic correlation, 0.44 to 0.68 (WG) and 0.23 to 0.56 (FGR), and the phenotypic correlation, 0.30 (WG) and 0.17 (FGR), were positive when evaluated in the same trait between collective or individual environments; correlations between traits in the same or in different environments were negative, or almost null. It can be concluded that use of performance testing, in individual cages, for WG and FGR, can result in genetic progress when progenies are raised in collective environments, as there is a small re-classification of the breeders from one environment to another.

Realizaram-se seis análises bicaráter. No teste de desempenho foi observado que as características ganho de peso e conversão alimentar em ambos os ambientes tiveram valores para herdabilidade que variam de 0,42 a 0,60. Tanto a correlação genética 0,44 a 0,68 (GP) e 0,23 a 0,56 (CA) como a fenotípica 0,30 (GP) e 0,17 (CA) foram positivas para a mesma característica quando avaliada nos dois ambientes, coletivo ou individual, e foram negativas ou mesmo nulas, quando entre característica no mesmo ambiente ou em ambientes diferentes. Conclui-se que o uso do teste de desempenho em gaiolas individuais tanto para ganho de peso como para conversão alimentar, pode resultar em progresso genético quando suas progênies forem criadas em ambiente coletivo, visto que houve pequena mudança na reclassificação dos reprodutores de um ambiente para outroEditora da Universidade Estadual de Maringá2010-03-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de Campo; Metodologiaapplication/pdfapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/626210.4025/actascianimsci.v32i1.6262Acta Scientiarum.
