Research advances of intramuscular fat for commercial pigs

Intramuscular fat(IMF) content is one of major determinants of pork quality.Intramuscular fat affects pork quality by flavor,juiceness and muscle tenderness,and so on.Therefore,it' s an effective way to improve meat quality by altering the content of intramuscular fat.The deposition of intramuscular fat can be regulated by many factors such as gene,nutrition,environment,and so on,in which the factors of gene and nutrition are often researched,in the contrary to the effect of environment and sex which have a certain extent effect on deposition of intramuscular fat.In this article,the advance in the research of regulation of intramuscular fat for commercial pigs was summarized for higher quality pork and guiding the production.
