Breeding method for improving lean meat percentage of fattening pigs

Abstract

The invention discloses a breeding method for improving the lean meat percentage of fattening pigs, and relates to the technical field of pig breeding. The pigs are sequentially driven to a 1.0-1.2m high diving platform for diving before the pigs are fed with feed every day at noon, a water tank is arranged on the lower portion of the diving platform, the depth of the water tank is 30-35cm, the pigs are driven to the diving platform for repeated diving after diving, diving movement is kept for 12-15 minutes, the pigs freely move for 5-10 minutes and then are fed with the feed, and the pigs freely drink water. The pigs do diving movement for a certain time before feeding, the feed with added starch and lightyellow sophora root mixed fermentation materials is fed to the pigs after diving movement, the muscle tension and the carcass quality of the fattening pigs can be improved by movement, strength can be effectively and timely replenished by feeding the feed with the added starch and lightyellow sophora root mixed fermentation materials after movement, the lean meat percentage can be effectively increased, and fat percentage is reduced.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and in particular relates to a breeding method for increasing the lean meat rate of fattening pigs. Background technique [0002] Pork is the most common animal product on the table of Chinese people. At present, in order to increase the meat output of pigs and improve economic benefits, many pig farms have to fatten pigs during the pig fattening stage. For this reason, many pig farms directly feed concentrated feed Rapid fattening, although this method can achieve the purpose of rapid fattening, but due to the large use of concentrated feed, the cost is high, and the feed additives are still mainly chemical synthesis, these feed additives bring some side effects more or less, and there will be residual In the pig body, it will eventually bring different degrees of harm to the human body through the food chain; consumers generally complain that the meat is rough and lacks flavor, the fatty a...

[0002] Pork is the most common animal product on the table of Chinese people. At present, in order to increase the meat output of pigs and improve economic benefits, many pig farms must fatten pigs during the pig fattening stage. For this reason, many pig farms directly feed concentrated feed Fast fattening, although this method can achieve the purpose of fast fattening, but due to the large amount of concentrated feed, the cost is high, and the feed additives are still mainly chemical synthesis, these feed additives bring some side effects more or less, and there will be residual In the pig body, it will eventually bring different degrees of harm to the human body through the food chain; consumers generally complain that the meat is rough and lacks flavor, the fatty acid composition and other fat-soluble substances in the subcutaneous fat and lean tissue of pigs, and these substances are harmful to human body. The flavor of the pork is affected
