Abstract

A breeding method for a new strain of Jianyang big-eared sheep relates to the technical field of animal breeding, in particular to a breeding method for a new strain of Jianyang big-eared sheep. The purpose of the invention is to provide a goat breed with fast growth and development, strong adaptability, high meat production rate and slaughter rate, and a reproduction rate of more than 210%. After long-term selection and breeding, the present invention has the conditions of an excellent population in terms of quality, quantity and genetic performance, and has formed a population with high reproduction rate, large individual, fast growth and development, good meat production performance, rough feeding resistance, and strong disease resistance. , good leather, tender meat, no smell and other characteristics of the variety, and basically formed an excellent variety with relatively stable genetic performance and a certain population size, which is easy to promote.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a method for breeding a new strain of Jianyang big-eared sheep. Background technique [0002] The breed plays a key role in the development of meat goat production. There are more than 150 goat breeds in the world, and there are fewer meat breeds. The world-famous meat breeds-Boer goat, Kajin goat, and Siler goat are also local breeds, with a narrow distribution area. There are still a large number of undeveloped goats that provide mutton.
