Abstract

The invention relates to a method for culturing a high-quality efficient stress-resistant complete set line of large white pigs, which comprises the following steps of: building a basic group based on gene identification and disease resistance verification of F18 colibacillosis resistant major genes FUT1M307 of a core group, and culturing the high-quality efficient stress-resistant complete set line of the large white pigs by combining immunology principle, molecular breeding technology and conventional breeding means and using a candidate gene strategy. The complete set line pigs have the advantages of stress resistance, strong environmental adaptability, weaned piglet diarrhea and edema disease resistance, high lean meat rate, excellent meat quality, high feed reward and high birth number.

Description

technical field

[0001] The invention belongs to the technical fields of animal genetics, breeding and reproduction, and molecular biology, and in particular relates to a method for cultivating high-quality and high-efficiency Large White pig stress-resistant matching lines. Background technique

[0002] Since the founding of the People's Republic of China, especially since the reform and opening up, great progress has been made in the introduction, breeding and utilization of foreign breeds of pigs, which have greatly improved the national pig slaughter rate (62.1% in 1980 and 129.9% in 2003), carcass weight (1980 was 129.9%), 57.1kg in 2003, 76.6kg in 2003), carcass lean meat percentage, improved seed coverage and economic benefits played an important role. Looking at the current large-scale lean-meat pig breeding system in the domestic pig industry, foreign three-way hybrid commercial pigs have an absolute advantage. The implementation, the establishment of artificial ins...
