High-efficiency breeding method of goat for achieving one birth of multiple goats

Abstract

The invention provides a high-efficiency breeding method of goats for achieving one birth of multiple goats. The method comprises the steps that (1), synchronous estrus regulation is conducted, and amethod of CDIR+PMSG is adopted; (2), superovulation regulation is conducted, and a method in which an FSH diminishing method cooperates with PG and lutropin to release hormone A3 is adopted; (3), studram hybridization is conducted; (4), nutrient regulation is conducted, and each goat is fed with dried grass and fine feed. According to the method, processing is conducted by using exterior hormonesso that the breeding of the goats can be improved to 3-4 goats for one birth, one birth of multiple goats is achieved to increase the goat production amount, the reproduction rate of the goat is greatly increased, economic benefits of goat raising is improved and the confident of farmers is improved. The method has the advantages that the cost is low, the operation is intramuscular injection which is simple and convenient, and subsequent complicated work is reduced by means of self hybridization of stud ram, which is beneficial for being popularized and used among the farmers.

Description

technical field [0001] The invention belongs to the field of animal husbandry reproduction and breeding, in particular to a high-efficiency breeding method for goats with multiple lambs per litter. Background technique [0002] Nowadays, the development prospect of the goat breeding industry is good. With the government's policy support, a large number of farmers have begun to raise goats. The economic benefit of meat goats depends on the reproductive rate of goats, which is not as high as that of sheep. Under natural conditions, one lamb is generally produced, and a few produce two lambs, and the reproductive cycle is relatively long. This greatly limits the development of goat breeding. Therefore, using modern technology to improve the number of lambs per litter of goats has become the key to solving the benefits of goat breeding. [0003] Local goat breeding in Guangxi is mainly grazing and breeding. Breeding occurs in natural estrus. The gestation period is generally r...

AI Technical Summary

Problems solved by technology

[0003] The local goat breeding in Guangxi is mainly grazing and breeding. They are bred in natural estrus. The pregnancy period is generally relatively long, about 6 months, and the average litter is 1-2 lambs, reaching three litters in two years. The reproductive efficiency is low.

Many farmers gave up raising goats due to low income, which seriously hindered the development of local goat breeding industry in Guangxi
