Economic crossbreeding method for increasing benefit of pure breeding pig farm

Abstract

The invention relates to an economic crossbreeding method for increasing the benefit of a pure breeding pig farm, belonging to the field of animal genetic breeding. The economic crossbreeding method comprises the following steps of: 1) pure breeding: dividing a purely bred pig herd into two parts, i.e. a nucleus herd and a production herd, determining a scale of the nucleus herd according to a variety breeding target or a breed conservation plan, and taking pigs which do not function as the nucleus herd as the production herd; and 2) economic crossbreeding method: focusing on crossbreeding as for sows of the production herd, and alternately carrying out pure breeding and crossbreeding on sows of the nucleus herd. The crossbreeding advantages cannot be utilized in pure breeding of the pigs, and the economic benefit of the purely bred pigs is often lower, in particular to Chinese native pigs and pigs in bred variety. If economic crossbreeding is properly carried out in the pure breeding pig farm under the condition of ensuring to finish a pure breeding task, the economic benefit of the pig farm can be greatly increased.

Description

[0001] 1. Technical field [0002] The invention relates to an economical hybridization method for improving the benefit of a purebred pig farm, which is a method combining purebred pig breeding and hybrid utilization, and belongs to the field of animal genetics and breeding. 2. Background technology [0003] The method of mating and breeding male and female pigs of the same breed is called purebred breeding. The method of mating male and female pigs between different breeds or strains is called crossbreeding; in order to maximize the use of the genetic potential of pig breeds and improve economic benefits, hybridization is called economic hybridization. Commercial pigs produced by economical hybridization are mostly viable. Strong, fast growing and high feed remuneration. [0004] Through purebred breeding to expand the purebred pig herd, and then through selection and matching, directional breeding, so as to further improve and develop the excellent characteristics of pu...

AI Technical Summary

Problems solved by technology

For large-scale breeding farms, it is possible to separate pure breeding farms and hybrid commodity farms; for small and medium-scale breeding pig farms, it is difficult to separate pure breeding and hybridization farms; Only purebred selection can be carried out

But purebred breeding is often economically stressful
