Abstract

The present invention proposes a breeding method between Nubian goat and Hainan black goat. In the present invention, Nubian goat is introduced into Hainan black goat breed for hybridization, and Hainan black goat is used as the female parent and Nubian goat is used as the male parent for hybridization. , carry out cross-crossing among the F1 generation hybrids to obtain the F2 generation cross-cross hybrids, cross the F2-generation cross-cross hybrids as the male parent, and Hainan black goat as the female parent to obtain the F3 generation hybrids, and use the F3 generation hybrids as the female parent The male parent and Hainan black goat were crossed to obtain the F4 generation hybrid, and the excellent female parent of the F4 generation hybrid and the excellent male parent of the F4 generation hybrid were cross-crossed to obtain the F5 generation cross hybrid, closed-breeding , Expansion group. The invention effectively inherits the genetic advantages of Nubian goats such as fast growth, high reproduction rate, delicious meat and high meat yield, and the reproduction rate of ewes is increased from the original 150% to more than 200%. The breeding method of the invention effectively improves the meat yield, growth rate and fecundity of the Hainan black goat.

Description

technical field [0001] The invention belongs to the technical field of goat breeding, and in particular relates to a breeding method for Nubian goats and Hainan black goats. Background technique [0002] Hainan black goat is the only local fine goat breed in Hainan Province. It is distributed in various cities and counties in Hainan. It has the advantages of resistance to rough feeding, high temperature and high humidity, strong disease resistance, early sexual maturity, and good meat performance. It is a valuable variety resource for large-scale breeding in tropical areas of China. However, the existing Hainan black goats are relatively small. The average body weight of 6-month-old rams is 16-18kg, and that of ewes is 14-16kg. The average weight of adult ewes is 45-50 kg, and the average weight of adult ewes is 40-45 kg. The reproductive rate is low. Generally, only one litter per year or three litters in two years are produced. In order to meet the needs of the market, i...
