| Outline of Final Research Achievements |
This study was to conduct the fattening evaluation by characterizing the fat accumulation and endocrine regulation in single nucleotide polymorphism of bovine growth hormone (bGH). (1) GH gene polymorphism changed the oleic acid composition in the intramuscular fat by regulating the SCD-1. (2) Response to GH stimulation was different depending on the GH genotype. (3)Insulin has an action to suppress the secretion of GH acts directly on the anterior pituitary, GH secretion is increased by changes in stress and NEFA concentrations caused by the sharp reduction in blood glucose levels in vivo. These results indicate that endocrine regulations such as insulin may different by GH polymorphism of Japanese Black Cattle, affecting the meat quality and production due to changes in fat accumulation.
