Black pig breeding method

Abstract

The invention discloses a black pig breeding method. The black pig breeding method comprises the following steps that firstly, a primary group is selected, a purebred Meishan pig is selected as a female parent and a purebred Tibetan pig is selected as a male parent, hybridizing is carried out, and after the Meishan pig female parent farrowing, a sow piglet is selected as a first-generation female parent for later use; secondly, a second-generation group is selected, the first-generation female parent piglets in the first step are bred to an estrus period, purebred Wujin pigs are selected as male parents, hybridizing is carried out, and sow piglets are selected as second-generation female parents for later use after the first-generation female parents give birth; thirdly, breeding pigs are selected, purebred Duroc pigs are selected as male parents for hybridization when the second-generation female parent piglets in the second step are fed to the estrus period, and the piglets are taken as the breeding pigs after the second-generation female parents give birth; and fourthly, the breeding pigs are bred, and in the breeding process, the breeding pigs are fed with feed three times. The piglets bred through the breeding method are high in growth speed and high in disease resistance, meanwhile, the feed is used for feeding the piglets, growth of the piglets can be promoted, and the feeding amount and the disease resistance of the piglets are improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for breeding black pigs. Background technique [0002] In my country, in terms of pig breeds, there are Chinese black pigs, foreign foreign pigs, and Chinese wild boars. Under normal circumstances, the breeds used for breeding are mainly domestic black pigs and foreign foreign white pigs for hybrid breeding. At present, domesticated wild boars are also raised as commercial products. As far as the breeds of pigs are concerned, domestic black pigs have black hair, more fat and less lean meat, are resistant to coarse feed, have slow production speed, good taste, and poor commodity quality. However, foreign foreign pigs have less fat, high lean meat percentage, more feed requirements, fast growth, short growth cycle, poor taste and good commerciality. In order to obtain fast-growing pig breeds, under normal circumstances, domestic black pigs and foreign foreign pigs are used as ...

AI Technical Summary

Problems solved by technology

However, due to the disorder of pig breeds, the provenance of commercial piglets is unclear, so the piglets after hybridization have variable genes and are prone to bad traits, which affect the feedability, commerciality and meat quality of offspring pigs. At the same time, in the feed In terms of selection, existing feeds generally lead to excessive growth of pigs, resulting in poor meat texture, low meat quality and nutritional value, and poor disease resistance of individuals
