Trinta e quatro touros Nelore (Bos taurus indicus) e 10 Pantaneiros (Bos taurus taurus) foram submetidos a teste de libido em dois anos consecutivos, numa mesma propriedade no Pantanal Mato-grossense. Avaliou-se os efeitos de raca e de ano da realizacao do teste sobre: Tempo para o primeiro contato com a femea (TIS) e Tempo de reacao para o servico completo (TR) e a frequencia de periodos de inatividade, cheirar cabeca/flanco/etc., reflexo de Flehmen, cheirar ou lamber regiao genital, cheirar ou lamber regiao genital seguido de Reflexo de Flehmen, perseguicao ativa, exposicoes parciais ou totais do penis, contracoes prepuciais, impulso de monta, tentativa de monta, monta abortada e servico completo. Houve efeito da raca (P<0,05) sobre o TIS, cheirar a vulva associado ao reflexo de Flehmen, contracoes prepuciais e monta abortada. O ano do teste influenciou significativamente (P<0,05) a maioria dos comportamentos, o que segeriu uma baixa repetibilidade das medidas. A ocorrencia do impulso de monta e a baixa fequencia de tentativas de monta e de servicos completos, podem ser resultados da acao da selecao natural, uma vez que estas ultimas atividades gerariam uma elevacao na temperatura corporal, o que nao e desejavel num, ambiente quente e umido. A ocorrencia do impulso de monta pode ser um comportamento mais adequado para o macho avaliar a receptividade da femea em cio em ambiente tropical. |

Abstract Background: Excess fat content in chickens has a negative impact on poultry production. The discovery of QTL associated with fat deposition in the carcass allows the identification of positional candidate genes (PCGs) that might regulate fat deposition and be useful for selection against excess fat content in chicken’s carcass. This study aimed to estimate genomic heritability coefficients and to identify QTLs and PCGs for abdominal fat (ABF) and skin (SKIN) traits in a broiler chicken population, originated from the White Plymouth Rock and White Cornish breeds. Results: ABF and SKIN are moderately heritable traits in our broiler population with estimates ranging from 0.23 to 0.33. Using a high density SNP panel (355,027 informative SNPs), we detected nine unique QTLs that were associated with these fat traits. Among these, four QTL were novel, while five have been previously reported in the literature. Thirteen PCGs were identified that might regulate fat deposition in these QTL regions: JDP2, PLCG1, HNF4A, FITM2, ADIPOR1, PTPN11, MVK, APOA1, APOA4, APOA5, ENSGALG00000000477, ENSGALG00000000483, and ENSGALG00000005043. We used sequence information from founder animals to detect 4843 SNPs in the 13 PCGs. Among those, two were classified as potentially deleterious and two as high impact SNPs. Conclusions: This study generated novel results that can contribute to a better understanding of fat deposition in chickens. The use of high density array of SNPs increases genome coverage and improves QTL resolution than would have been achieved with low density. The identified PCGs were involved in many biological processes that regulate lipid storage. The SNPs identified in the PCGs, especially those predicted as potentially deleterious and high impact, may affect fat deposition. Validation should be undertaken before using these SNPs for selection against carcass fat accumulation and to improve feed efficiency in broiler chicken production.
