Research Progress on Efficient Production of High Quality Marbling Beef
Marbling beef is famous for its fat in the muscle distributed evenly like snowflakes,this kind of meat is not only delicate and juicy,but also has high nutritional value,which is loved by consumers.So how to efficiently produce marbling meat is an immi-nent problem in China. The production process of marbling meat is a complex process involving a variety of factors. In recent years,a lot of research has been carried out at home and abroad on how to improve meat quality. The paper elaborates on the effects of in-termuscular fat deposition from the growth and development mechanism of muscle and fat cells,genetic factors (breed,heritability,sex),nutritional factors (feeding practices,dietary nutrient level),and management factors (environmental management,pre-slaugh-ter transportation,post-slaughter acid excretion),with a view to providing theoretical references to promote the sustainable develop-ment of China's beef industry.
