| Research Abstract |
We investigated the relationship between GH gene SNP and beef production in Japanese Black cattle. (1) C-type allele was for fat production in high-fat meat although A-type allele was profitable for milk production. (2) A-type allele was profitable for carcass weight, dairy gain, BMS and so on, while C-type allele was profitable for unsaturated fatty acid production in meat. (3) A-type allele showed a significant relationship with greater gene expression of SCD and FASN, while C-type allele showed that with lower SCD expression. (4) GHRH-induced GH release in C-type animals was smallest among all types. (5) The effects on meet production was greater for heifers than for bulls.
