Resumen:
Age at puberty is an important component of reproductive performance in cattle, so it is important to identify genes that contribute to the regulation of the onset of puberty and polymorphisms that explain differences between bulls. In a previous study, we found putative associations between SNPs in chromosomes 1 and X and age at puberty in Angus bulls. In the present work we aimed to confirm these findings in a larger sample of Angus bulls (n=276). Four SNPs located into these regions were genotyped using SEQUENOM technology and the obtained genotypes were associated with age at puberty. The results showed that SNPs rs135953349 and rs110604205 on BTA1 were still significantly associated with age of puberty estimated at progressive sperm motility of 10% (p
