1, feed weight in the 20 kg to 50 kg stage, crude protein requirements in 16%, weight 60 kg to 90 kg stage, only 14% of sperm protein, and lysine, methionine, cystine and other important trace elements and Vitamins must be added in a certain proportion.

2. Breeding adopts rearing technology with “before opening and controlling”. “Before open” means that pigs are fed or freely fed multiple times a day before 50 kg of body weight. The feed is free from restrictions, allowing the pig to grow freely and quickly; when the weight exceeds 50 kg, it begins to limit the amount of food consumed by pigs. In addition to ensuring adequate drinking water, only two meals are to be eaten, and each meal is fed only 80% satiety, which is called "post-control." Because after 50 kilograms of pigs, fat is mainly deposited and growth is accelerated. If the pigs are fed too full, the pigs will grow more fat, and the lean meat will be reduced, and no lean pigs will be raised.

3. The lean meat percentage of pig breeds in China is currently only about 41%, and the ternary crossbreed pigs with "Durok and Landrace and Erhualian" have a lean meat weight of up to 49 kg. The lean meat rate is above 54%.

4. Control experiments show that when the pigs weigh between 40 kg and 60 kg, the daily growth of lean meat is about 288 g and the fat is about 280 g; after 90 kg, the long lean meat is up to 120 g per day, but the long fat is More than twice as lean meat. Therefore, lean-type pigs should be slaughtered after 90 kg to 100 kg, so as to avoid the shortage of lean meat.
