Growth hormone and pituitary specific transcription factor-1 are expressed in the pituitary gland and play critical roles in the development and growth of mammals. Genetic polymorphisms of GH1 and POU1F1 genes were investigated using PCR-RFLP and tested for statistical associations with meat quality traits in Hanwoo cattle. Three genotypes were found for each gene in a population of Hanwoo steers reared for beef production. No meat quality traits were significantly associated with the GH1 genotypes. Animals with the GH1 Leu/Leu genotype had heavier weights and higher marbling scores, but statistical significance was not detected. Backfat thickness was associated with POU1F1 genotypes. Backfat of POU1F1 G/G homozygotes was thicker than that of other genotypes (p < 0.05). Other carcass traits, including weight at slaughter, carcass weight, carcass yield ratio, eye muscle area, marbling score, meat color, and fat color were statistically insignificant in POU1F1 genotypes (p > 0.05). These findings suggest that the POU1F1 G/G genotype may contribute to improving body weights and backfat in Hanwoo steers using sire-based predictions.
