Problems solved by technology

[0003] Compared with high-yielding lean-meat pig breeds, domestic local pig breeds are famous for their germplasm characteristics such as resistance to rough feeding, anti-stress, large litter size, good meat color, high fat content, and good flavor. And feed conversion rate is low, it is difficult to go through in commodity production

Embodiment Construction

[0017] The present invention takes Zhejiang Zhongbai pig, Jiaxing black pig and Berkshire pig as parental resources, successively establishes binary and ternary hybridization production systems, and develops the comprehensive meat production performance evaluation of hybrid offspring growth, carcass and meat quality. For details, see figure 1 .

[0018] 1) Using Zhejiang Zhongbai pig with Jinhua bloodline as the female parent and Jiaxing Black pig as the male parent to produce Jia-Zhejiang binary hybrid pigs.

[0019] The specific technical plan is as follows: (1) Select 30 multiparous sows (2-3 litters) of Zhejiang Zhongbai pigs, purchase the semen of 7 pedigree boars from the local sperm supply station in Jiaxing, and use artificial insemination for crossbreeding. (2) Record the coat color of the offspring, measure the birth weight, weaning weight, age at 30kg body weight, age at 100kg body weight, backfat thickness at 100kg body weight, eye muscle area and estimated lean me...

Abstract

The invention relates to a hybrid breeding method of a quality pig. The hybrid breeding method of the quality pig comprises the following steps: 1) a Zhejiang middle white pig containing Jinhua pig blood acts as a female parent and a Jiaxin black pig acts as a male parent, and a Jiaxin-Zhejiang binary hybrid pig is bred; and 2) the Jiaxin-Zhejiang binary hybrid pig acts as a female parent and a Berkshire pig acts as a male parent, and a Berkshire-Jiaxin-Zhejiang three-way hybrid pig is bred. With the adoption of the hybrid breeding method, a growth rate and a meat factor of three-way hybrid offspring are increased by 5-10% than those of Jiaxin-Zhejiang binary hybrid offspring, particularly an eye muscle area is increased by 30%; the amplitude of variation in meat flavor is little, particularly the intramuscular fat content is remained at 3-4% (ideal meat level); the marbling characteristic is very obvious; and the meat quality characteristics of the Berkshire pig and the domestic local pig are combined.

Description

technical field [0001] The invention relates to a pig hybrid production method. Background technique [0002] Looking back on nearly half a century of hard work, the commercial pigs in the world are almost covered by high-yielding lean pig hybrids such as Duroc, Landrace, and Large White. This has made a huge contribution to meeting people's demand for pork production, and it has also led to a further distance from the "fresh and tender" feeling of pork in memory. With the continuous improvement of people's living standards today, people begin to pay more attention to the quality, flavor and nutritional safety of pork. [0003] Compared with high-yielding lean-meat pig breeds, domestic local pig breeds are famous for their germplasm characteristics such as resistance to rough feeding, anti-stress, large litter size, good meat color, high fat content, and good flavor. And feed conversion rate is low, it is difficult to get through in commodity production. By gathering high...
