Abstract

The invention discloses a method for cultivating a hybrid new line of Guizhou white goat and Nubian goat. An offspring with high meat yield, high fecundity and fast growth rate is obtained through hybridization breeding of Guizhou white 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 white goat and the Nubian goat F1 generation; then the Bainu hybrid sheep is obtained by hybridization of a Guizhou white goat ram and the F1 generation; and finally, the Bainu hybrid sheep is subjected to transversefixation 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 white 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.

Description

technical field [0001] The invention relates to the technical field of stockbreeding and breeding, in particular to a breeding method for a new hybrid strain of Guizhou white goat and Nubian goat. Background technique [0002] As an excellent local breed in Guizhou, Guizhou white goat is mainly produced in Yanhe, Sinan, Wuchuan and other counties in the middle and lower reaches of Wujiang River in Northeast Guizhou. Both male and female sheep have horns and beards under the jaws, rams have curly hair on their necks, and a few ewes have a pair of wattles under their necks. This variety has the characteristics of tender meat, good meat production performance, fat distribution between muscles, strong and soft skin, and dense fibers. However, there are also disadvantages such as small size, slow growth rate, and low economic benefit. [0003] Nubian goat is currently the fastest growing and largest goat breed in my country. Adult rams generally weigh more than 100 kg, and adul...
