Method for breeding new hybrid strain of Boer goats and Beichuan white goats

Abstract

The invention belongs to the technical field of ruminant breeding, and particularly relates to a method for breeding a new hybrid strain of Boer goats and Beichuan white goats. The method for breedingthe new hybrid strain of the Boer goats and the Beichuan white goats is good in meat production performance, high in meat yield and high in growth speed. The method comprises the following steps: (1)taking a Boer goat as a male parent and a pure Beichuan white goat as a female parent, and hybridizing to obtain a F1-generation Bobei binary goat; (2) taking the F1-generation Bobei binary goat as an ancestor male parent, and taking a pure Beichuan white goat different from the pure Beichuan white goat in the step (1) as a female parent to obtain F2-generation Beichuan hybrid white goat; and (3)fixing the F2-generation Beichuan hybrid white goat obtained in the step (2) through three generations of crossbreeding to obtain the Beichuan white goat hybrid new strain. The goats bred by the method disclosed by the invention are high in growth speed, good in meat production performance and high in meat yield, and meanwhile, the new strain is fine and tender in meat quality and delicious and juicy in taste, so that the economic and feeding value is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ruminant breeding, and in particular relates to a method for cultivating a new hybrid strain of Boer goat and Beichuan white goat. Background technique [0002] The Beichuan white goat is an excellent local goat population spontaneously formed by the Qiang people after long-term closed breeding and extensive management without systematic breeding under specific ecological conditions. Beichuan white goat has white coat, handsome appearance, docile temperament, strong limbs, strong adaptability, good reproductive performance, excellent meat production performance, delicious meat quality, and low smell. [0003] Beichuan white goats are mainly distributed in Beichuan, Pingwu, Jiangyou, Anzhou, Maoxian, Songpan and other counties and cities. The main production areas are the middle and low mountainous areas in Beichuan County, with the largest number of villages and towns such as Chenjiaba, Qushan, Xuanping,...

AI Technical Summary

Problems solved by technology

[0004] The Beichuan white goat industry suffered serious losses. Firstly, there were multiple impacts such as changes in the living environment and the post-disaster reconstruction and relocation of the breeders; decline, the species degenerates seriously, the purity of the provenance is greatly reduced, the production performance is significantly reduced, the incidence of epidemic diseases is increased, the breeding efficiency is relatively low, and the breeding profit is difficult to sustain, and even the annual inventory is less than 100,000.
