Outline of Final Research Achievements

The present study revealed that gene expression in skeletal muscle is related to beef productivity in various feeding environment of fattening steers. Monitoring gene expression in the skeletal muscle can be indicative of biological reactions, such as the protein and fat accumulation in the skeletal muscle, during fattening period of beef cattle, which may be able to provide useful information to improve fattening systems. Although the present study measured the expression of limited genes belonging to four groups, expression analysis of more gene in several groups may be able to obtain a large amount of information about the living body. To improve fattening systems based on gene expression, further studies are needed to elucidate the relationship between gene expression and beef production, including the growth and carcass performance and nutrient contents in the skeletal muscle.
