Abstract

The invention provides a method for breeding Nubia goats and Hainan black goats. The method disclosed by the invention comprises the following steps: introducing Nubia goats into Hainan black goat varieties for hybridizing, taking the Hainan black goats as a female parent and taking the Nubia goats as a male parent for hybridizing, crossing in F1 generation hybrid variety so as to obtain the F2 generation crossing hybrid; taking the F2 generation crossing hybrid as a male parent and taking the Hainan black goats as a female parent for hybridizing so as to obtain the F3 generation hybrid; taking the F3 generation hybrid as a female parent and taking the Hainan black goats as a male parent for hybridizing so as to obtain the F4 generation hybrid; crossing excellent female parents in the F4 generation hybrid and excellent male parents in the F4 generation hybrid so as to obtain the F5 generation crossing hybrid; performing enclosed breeding, and expanding population. According to the method disclosed by the invention, the gene advantages of the Nubia goats such as fast growth, high reproduction rate, delicious meat, high meat percentage and the like are effectively inherited, and the reproduction rate of ewes is increased from the original 150% to 200% or higher. According to the breeding method disclosed by the invention, the meat yield, production rate and reproductive capacity of the Hainan black goats are effectively improved.

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...
