Method for breeding new variety of Taihang black goats

Abstract

The invention discloses a method for breeding a new variety of Taihang black goats. In the breeding method, a three way cross among a Taihang black goat, a Jintang black goat and a Nubian is performed, and individual bulk selection is used for selective breeding and propagation to breed the new variety of Taihang black goats. In the breeding method of the invention, by introducing the advantageous genes associated with the large body size, high yield and high milk productivity of the Jintang black goats and Nubian goats are introduced, the bred new variety of the Taihang black goats, apart from the characteristics of high adaptively and complete black hair of the Taihang black goat, has the advantages of large body size, high growing speed, high meat production capacity, high milk productivity and the like. Compared with Taihang black goats, the new variety has the advantages that: the lambing percentage is as high as over 150 percent; the growing speed is high; the body size is so large as the weight of a mature male goat is over 55 kilograms and the weight of a female goat is over 40 kilograms; the meal productivity is high; the meat quality is high; the milk yield is high; and the adaptability is high. Thus, the method is suitable for drylot feeding and market lamb production development.

Description

technical field [0001] The invention relates to a method for cultivating a new strain of Taihang black goat, belonging to the technical field of animal cultivation.
