Pig breeding system

Abstract

The invention provides a pig breeding system. The pig breeding system comprises the following steps: determining female parent, determining male parent, carrying out crossbreeding so as to obtain a commercial pig, and subjecting the crossbred commercial pig to precise feeding. The flow of precise feeding is as follows: in 0 to 2 week, carrying out breastfeeding; in 1 to 2 weeks, supplementing a suckling pig feed, and feeding a traditional Chinese herbal broth a; in 2 to 7 weeks, carrying out weaning, feeding the suckling pig feed, and feeding the traditional Chinese herbal broth a; in 7 to 18weeks, feeding a feed a, feeding a traditional Chinese herbal broth b, and spraying the traditional Chinese herbal broth b into the feed a; in 18 to 23 weeks, feeding a feed b, feeding the traditionalChinese herbal broth b, and spraying the traditional Chinese herbal broth b into the feed b; and in 23 weeks to the time of marketing, feeding a feed c, and spraying the traditional Chinese herbal broth b into the feed c. The pig breeding system provided by the invention synthetically researches breeding of a synthetic line of hybrid pips for excellent Large White pigs, controls precise feeding in the process of breeding at the same time, forms a novel live-pig variety with local characteristics, improves the quality of pork and enhances the efficiency of breeding.

Description

technical field [0001] The invention relates to a breeding method, in particular to a pig breeding system. Background technique [0002] With the further deepening of my country's overall construction of a harmonious and well-off society and the further improvement of the people's material and cultural level, the market has higher and higher requirements for the quality of pork products. People are not only satisfied with enough lean pork in the market, but also demand that they can buy Tender, juicy, flavorful lean pork. Therefore, improving lean meat percentage and muscle quality, and researching and cultivating new strains with high quality, high yield and flavor characteristics have become the main research directions of pig breeding. However, only using crossbreeding between breeds cannot guarantee the stable inheritance of outstanding characters, and often causes capricious variation in the performance of hybrid commercial pigs, and the consistency is poor. Some pig-ra...

Problems solved by technology

However, only using crossbreeding between breeds cannot guarantee the stable inheritance of outstanding characters, and often causes capricious variation in the performance of hybrid commercial pigs, and the consistency is poor. Some pig-raising developed countries have started a production package since the 1970s The new mode of breeding and breeding is developing towards the breeding direction of homogeneous trait combinations among breeds, and the pig breeding stage of synthetic line hybridization to produce hybrid pigs is started. At present, the famous hybrid pigs in the world include Haiboer and Sige pigs. , Dika, Topek, etc., the daily weight gain of mixed-quality pigs is more than 800g, the lean meat rate is more than 65%, the feed conversion ratio is 2.4:1, the backfat thickness is 15-20mm, and the halothane gene is negative. Strains represented by Topek and other hybrid pigs adhere to SPE selection and breeding, and have established a good image of healthy pig raising in Shandong, Hubei Anlu and other places in my country, and have also established a model for developing original strains with their own local characteristics
