Comparative advantage of matching Line Pig and three-way Hybrid Pig

Matching line pigs have four major advantages: first, the lean meat rate is higher. The lean meat rate of the matching system is between 65% and 70%, and the "foreign three yuan" is between 60% and 65%. Second, the ability to reproduce is strong. The "matching system" gives birth to more than 12 babies, 5 babies in two years, 9 to 10 babies in "Yang Sanyuan", and 2 babies a year. Third, the growth cycle is shorter. It takes about 160 to 170 days to grow to 90 kg to 100 kg. Fourth, the cost is lower.
