Article Synopsis

The study investigates the roles of key genes (GHSR1a, GH, GHR, NCAPG, SCD) in growth and lipid metabolism traits in Japanese Black cattle.
Research involved analyzing 650 steers and 116 heifers for carcass traits, and 158 steers for fatty acid composition traits, revealing significant single and epistatic gene effects.
Findings suggest that a specific TG-repeat polymorphism in the GHSR1a gene is crucial for interactions affecting fatty acid composition in the cattle's adipose tissue.

The thermal property of bovine intramuscular adipose tissue (IAT) was evaluated using differential scanning calorimetry (DSC) and compared with the melting point temperature (MP) of the fat extract of IAT, which was measured using the slip point method. The beef samples were classified according to the beef marbling score (BMS). Beef with a high BMS contained less protein than that with middle or low BMS.
