Abstract: The aim of the present study was to verify associations between bull meat traits and 6 microsatellite loci. A sample of 66 weaned young bulls from Grassland Red Cattle (GLRC) and its improved hybrids by Limousine (LM) was characterized for BM2113, TGLA44, ETH225, IDVGA46, BM1824 and IDVGA55. The muscularity evaluation traits in the regulation of linear valuation and slaughtering meaty traits were used to evaluate their meat traits. The relationship between bull meat traits and 6 microsatellite loci was analyzed by SPSS. The results showed that for microsatellite BM2113, the allele 142 had a positive correlation with net meat weight and net meat rate; for microsatellite IDVGA46, the allele 211 had a negative correlation with the 5 muscularity evaluation and 4 slaughter meaty traits; for BM1824, the allele 171 had a positive correlation with Loin thickness; for microsatellite TGLA44, the allele 221 had a positive correlation with some muscularity evaluation traits such as withers, loin thickness, hip shape and some slaughtering meaty traits such as body weight, carcass weight and net meat weight.
