The lean meat percent of F01 was 43. 69 % to the fifth generations, which increased by 1. 54 percentage points. Its hog had excellent pork quality, it's intramuscular fat was 4. 77 % , and pH, LF, OPTO, tenderness and other indicators were within the range of excellence, and it's an ideal dam breeding.
