Problems solved by technology

As a result, the population size of purebred Chenghua pigs has shrunk sharply, and the Chenghua pigs on the market have almost disappeared. Currently, purebred Chenghua pigs are only raised in breeding farms, and the scale is small, and the price of provenance is high, and the cost of introduction is high.
[0005] At present, there is no method to use Chenghua pigs to breed special matching lines in the market, so there is a certain market potential

Abstract

The invention provides a method for culturing a high-quality specialized strain by using adult Hua pigs, and belongs to the technical field of livestock breeding. The method comprises the following steps: 1, selecting provenances of adult Hua pigs and Duroc pigs; 2, the Duroc boar and the adult Hua pig are hybridized to obtain a grading first-filial generation; 3, the duroc boars and the first-filial generation sows are hybridized to obtain grading second-filial generation; 4, hybridizing the Duroc boars and the second-generation hybrid sows to obtain a third-generation grading hybrid; 5, the duroc boars and the third-generation hybridized sows are subjected to mating, the duroc sows and the third-generation hybridized boars are subjected to mating, and fourth-generation hybridized boars are obtained; 6, carrying out cross-crossing fixation on the male and the sow of the grading filial generation to obtain a zero generation; and 7, repeating the step 6, performing cross-crossing fixed hybridization for one generation in one year, and breeding for multiple generations until appearance characteristics such as hair color and body type of offspring groups are neat and consistent, so as to breed a high-quality specialized strain.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and breeding, and in particular relates to a method for cultivating high-quality specialized strains by utilizing Chenghua pigs. Background technique [0002] China is the world's largest producer and consumer of pork, accounting for about 50% of the world's pork production and consumption, and has huge production potential and market demand. Chinese local pig breeds have excellent characteristics such as high fertility, strong resistance to stress, good meat quality, and strong adaptability. They are valuable genetic resources and an important guarantee for the sustainable development of China's pig industry in the future. However, due to the shortcomings of slow growth, long feeding cycle, low lean meat rate and low feed remuneration, local pigs are not suitable for China's current consumption needs, and are gradually marginalized by the market. Many local pig breeds are even on the ver...
