Culturing method of new strain of mutton goats with black heads and white bodies

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.

Description

technical field [0001] The invention relates to a method for cultivating black goat strains, belonging to the technical field of animal breeding. Background technique [0002] Macheng black goat is one of the excellent local black goat breeds in China. It has the characteristics of black coat, early maturity, strong fecundity and good meat quality. It is mainly distributed in the Dabie Mountains at the junction of Hubei, Henan, and Anhui, and is concentrated in Macheng, Hubei. In 2002, it passed the approval of the Hubei Provincial Livestock and Poultry Variety Approval Committee, and was included in the "Hubei Provincial Livestock and Poultry Breeds Records" (2004 edition), becoming an excellent local breed of black goat in Hubei Province. In January 2010, it was selected into the "National Catalog of Livestock and Poultry Genetic Resources" and became a national excellent black goat breed. Macheng black goat is a local breed that has not been systematically selected and ...

Problems solved by technology

[0003] China patent authorization announcement number CN 104017808 discloses a genetic marker related to goat growth traits and its application, but there is no specific breeding method for how to breed new breeds (lines) of mutton sheep

It does not solve the technical problem of hair color separation in goat hybrid offspring, and the hair color is difficult to stabilize
