The aim of this study was to evaluate the effect of environmental factors on the fertility of elite Brahman bulls, as well as polymorphisms with significant association with these characteristics. Eighteen bulls with satisfactory Breeding Soundness Examination (BSE) were reproductively monitored in two breeding seasons in herds with 50 females suitable for reproduction. Blood samples were collected from the bulls for DNA extraction and genotyping of 26 151 SNPs with the GGP-LD chip (Geneseek). The environmental effects and genotypes of SNPs on fertility characteristics were analyzed. The mating season and the reproductive status had a significant impact (p<0.05) on the percentage of normal sperm and the concentration of sperm. Genomic an...
