影响肉牛肌内脂肪沉积因素及相关基因的研究进展

Brief introduction to the research progress of factors and related genes influencing intramuscular fat deposition in beef cattle

肌内脂肪含量是影响牛肉品质的重要因素,直接影响肉的嫩度和风味。文章就肌内脂肪的形成、肌内脂肪含量与肉品质关系、影响肉牛肌内脂肪沉积因素及相关功能基因研究进行综述,为深入开展通过提高肌内脂肪含量改善肉品质和相关功能的基因研究提供参考。

Intramuscular fat content is an important factor to influence beef quality, which directly affects the meat tenderness and flavor. The intramuscular fat origin, relationship between intramuscular fat content and meat quality, the factors affecting intramuscular fat deposition and related genes are briefly reviewed in the paper, which provides a reference for deeply studying these functional genes by increasing intramuscular fat content to improve beef quality.
