Breeding method of a new strain of mutton sheep with black head and white body

Abstract

The invention provides a culturing method of a new strain of mutton goats with black heads and white bodies. The method is characterized in that a Boer goat is regarded as a male parent, a Macheng black goat is regarded as a female parent, and through a BLUP method, a marker-assisted selection (MAS) technology and combination of a conventional culturing method, by means of crossing fixup and embryo transplantation and propagation, the new strain of mutton goats with a high reproductive rate, a good meat performance and high temperature and humidity resistance are selected finally. According to the culturing method, the Macheng black goat is regarded as the female parent, the Boer goat is regarded as the male parent, and through the BLUP method, a multiple genes pyramiding technology and the combination of the conventional culturing method, the new strain of mutton goats with hair colors, high reproductive rate, meat performance and high temperature and humidity resistance is cultured; the characteristic of the black heads and white bodies is stable, the growth and meat performances of the new strain of the mutton goats are much higher than those of the Macheng black goat, the growth performance, the crude feed resistance, the disease resistance and the stress tolerance are higher than those of the Boer goat, and the production performance level of modern mutton goat breeds is achieved.
