The fat and thinness of pigs can be regulated.
After nearly a decade of scientific and technological research, Chinese scientists have discovered the mechanism of differentiation and regulation of pork fat cells, and made a major breakthrough in the use of biotechnology to control pork fat content. In this study, cell biology, molecular biology and other techniques were used to determine and analyze the growth and development of adipocytes, adipose tissue metabolism and related genes among different types of pigs, and a series of research results were obtained. This major achievement has recently passed the achievement evaluation organized by the Ministry of Education.
