Breeding method of a breed of sheep for multiple litter meat

Abstract

The invention provides a breeding method of a multiple-birth mutton sheep breed and relates to the technical field of animal breeding. The breeding method herein is characterized in that a Hu sheep, as a first male parent, an east eastfrierian sheep as a second female parent and a Tan sheep as a female parent are subjected to three-breed crossing; the novel multiple-birth mutton sheep breed suitable for the ecological conditions of loess plateau is cultivated through phenotypic screening in combination with screening of specific gene carriers; the multiple-birth mutton sheep breed is adaptiveto the natural ecological conditions of the loess plateau ecological region of China and has the advantages of good stress resistance, crude feeding resistance, high propagation rate, good meat tenderness, uniform fat distribution, little odor and the like.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a method for breeding sheep breeds with multiple fetuses. Background technique [0002] China is a big mutton production and consumption country in the world, but it is not a powerful country. The main reason is that China lacks professional mutton sheep breeds. 80% of mutton is produced from local breeds of sheep. Strong, but small in size, poor in meat production performance, low in slaughter rate and clean meat rate, unable to meet the needs of modern slaughtering and segmentation technology and high-quality mutton production. In addition, some local breeds have seasonal estrus, low lambing rate, low breeding efficiency, and low enthusiasm of farmers and herdsmen for breeding. As a result, some excellent local breed resources are on the verge of extinction, seriously affecting the protection and utilization of germplasm resources in China Therefore, making full use of...

AI Technical Summary

Problems solved by technology

However, Tan sheep are small in size, low in lambing rate, poor in meat production performance, low in slaughter rate and clean meat rate, and low in breeding benefits, which seriously affected farmers and herdsmen in production areas to get rid of poverty and increase their income and enthusiasm for breeding. The number of Tan sheep dropped sharply. In 2006 Included in the "National List of Livestock and Poultry Genetic Resources Protection" and became a national second-class protected species
