Abstract

The invention discloses a method for cultivating a hybrid new line of Guizhou black goat and Nubian goat. An offspring with high meat yield, high fecundity and fast growth rate is obtained through hybridization breeding of Guizhou black goat and Nubian goat, and the offspring with fast growth rate, high fecundity and high meat yield can be obtained by hybridization of the Guizhou black goat and the Nuhei F1 generation; then the Nuhei hybrid sheep is obtained by hybridization of a Guizhou black goat ram and the F1 generation; and finally, the Heinu hybrid sheep is subjected to transverse fixation of three generations, and the hybrid line sheep with high fecundity and fast growth can be obtained. The sheep retains the specific advantages of the Guizhou black goat, such as high reproductive rate, light mutton taste, delicious meat and good quality of skin, and inherits the advantages of the Nubian goat, such as tall property, fast growth rate and strong fecundity.
