| Research Abstract |
This experiment was conducted to determine the effect of energy and protein restriction during nursing period on intramuscular fat(IMF) accumulation of pigs. The restriction of energy and protein during the nursing period in pigs resulted in suppression of muscle development and this suppression was responsible for increased protein degradation and decreased protein synthesis, and increased total collagen contents in muscle, but no difference of IMF. While mRNA levels of collagen and lipid metabolism related genes were not changed. It was suggested that the feed restriction during nursing period resulted in suppression of muscle development, but no difference of intramuscular collagen type and IMF synthesis.
