Abstract

The invention discloses a method for cultivating highland high-quality black goat by virtue of hybridization of national and abroad goats. The method comprises the following steps: hybridizing an adventive Nubia goat used as a male parent with a Yunnan local Yunling mountain black goat used as a female parent, so as to obtain an F1-generation Nubia-Yunling hybrid black goat; performing grading hybridization on the Nubia goat used as the male parent and the F1-generation Nubia-Yunling hybrid black goat used as a female parent, so as to obtain an F2-generation Nubia-Yunling hybrid black goat; continuously performing grading hybridization on the Nubia goat used as the male parent and the F2-generation Nubia-Yunling hybrid black goat used as a female parent, so as to obtain an F3-generation Nubia-Yunling hybrid black goat; performing breeding and cross hybridization fixation on the F3-generation Nubia-Yunling hybrid black goat, so as to obtain a Nubia high-generation black goat variety applicable to growing in a high-altitude area. The Nubia high-generation black goat variety can be used for overcoming the defects of low general growth speed, low breeding rate, thick and hard flesh and the like of the Yunling black goat and has the advantages of cold resistance, coarse feed resistance, high farrowing rate, rapid growth speed, good flesh, high dressing percentage and the like.

Description

technical field [0001] The invention relates to the technical field of plateau black goat breeding, in particular to a method for breeding plateau high-quality black goats by crossbreeding Chinese and foreign goats, belonging to the field of animal genetics and breeding. Background technique [0002] Yunling black goat is mainly produced in the Yunling Mountain System and the extension areas of Ailao Mountain, Wuliang Mountain and Wumeng Mountain in the Yunling Mountain System and other veins in Yunnan Province. Its meat is delicious and thick, with high nutritional value. The protein content accounts for more than 22.6%, the fat content is less than 3%, the cholesterol content is 75% lower than pork, and 62% lower than beef and sheep meat. It contains more than 15 kinds of essential amino acids, especially The content of glutamic acid is high, reaching 13.03%. It has the effects of nourishing yin and strengthening yang, tonifying deficiency and strengthening the body, impr...
