The invention discloses a green healthy live pig breeding method. In the method, the pig house size, the feeding management, the feed management and the environmental management are scientifically controlled, wherein the feeding management comprises the following steps: after a piglet is born, the teeth are cut, the tail is broken, and an iron supplementation injection is given to the piglet within seven days, and in 11-13 days, castration is carried out, when the piglet is 20-22 days old, the pig is inoculated with swine fever vaccine, the pig is weaned and fed with suckling pig feed; after the pig is fed with the suckling pig for 9-11 days, the pig is fed with nursery feed, and when the pig is 14-16.5 kilograms, the pig is fed with piglet feed, and when the pig is 34-36 kilograms, the pig is fed with middle pig feed, and when the pig is 100-105 kilograms, the pig is fed with fattening feed. The feed management comprises the following steps: the weight ratio of one of the suckling pig feed, the nursery feed, the piglet feed, the middle pig feed or the fattening feed to forage is 1:2-2.5; and the pig is fed with the feed every 7-8 hours. The pig house environment can be well adapted to the growth of live pigs, occurrence of pig disease can be reduced, the daily gain of the live pigs can be increased, the feed-weight ratio can be reduced, the anti-disease ability of the live pigs can be improved, the meat quality of the pork is good, and the pork is green and safe.
