Breeding method of GBH plateau black pigs

Abstract

The invention discloses a breeding method of GBH plateau black pigs. The breeding method comprises the following steps of seed selection, hybrid breeding of breeding sows BG, hybrid breeding of breeding boars HG and hybrid breeding of GBH plateau black pigs. The bred GBH pigs are uniform in body type, the boars have the advantages of being few in skin disease, resistant to mosquito bite, high in disease resistance, resistant to coarse feed, large in snowflake meat, good in meat quality and the like when used for commodity fattening, the sows have the advantages of being high in stress resistance, resistant to coarse feed, obvious in oestrus, large in farrowing, high in maternity and the like, and the produced commercial pigs have the stable production performance of the large body type and the lean meat type. The variety has the characteristics of strong disease resistance and roughage resistance, so that the use of drugs and additives can be reduced, the variety is the first choice for developing plateau characteristic agriculture production green pork in Yunnan province, and the previous single cross breeding mode is overcome; the breeding method of the new black pig variety, which can be more suitable for the Yunnan plateau breeding environment, is realized.

Description

technical field [0001] The invention relates to the technical field of pig breeding, in particular to a breeding method for GBH plateau black pigs. Background technique [0002] Yunnan is located on a plateau with strong ultraviolet rays. Compared with the plain areas, the pig rearing conditions are relatively extensive. The foreign breeds of pigs introduced by the country in recent years are commonly raised in the Yunnan-Guizhou Plateau, and the skin is burned by ultraviolet rays, causing scale mites and skin diseases. The varieties also have the problems of slow growth rate, small size and more fat. With the increasing demand for special and high-quality black pork, the market is in urgent need of new breeds of black pigs with large body and lean meat. [0003] The existing breeding pig hybrid production technology is more of a simple use of foreign breeding pigs and Chinese local pigs. The coat color is mostly white. Compared with black pigs, white pigs not only have po...

AI Technical Summary

Problems solved by technology

[0003] The existing hybrid production technology of breeding pigs is more simply the use of foreign breeding pigs and Chinese local pigs for hybrid matching lines. Most of the offspring of the hybrids are white in color. Compared with black pigs, white pigs not only have poor pork flavor, especially in Yunnan. The disease resistance of white pigs in such high-altitude areas is generally worse than that of black pigs
