Short summary
Prosaposin (PSAP) is involved in muscle development and as a candidate gene in economic traits of cattle. Six novel SNPs of PSAP were identified and 47 traits in beef cattle measured. Association analysis revealed I10-65G > A, I10-162C > T, and E11-93C > G were significantly associated with carcass composition traits. Individuals with GCCCGC and ACCTCC haplotypes showed higher dressed weight, backfat thickness, and rib eye area, thus suggesting a genetic influence on cattle carcass composition.
