Breeding method for Puan black goat line

Abstract

The invention discloses a breeding method for a Puan black goat line. The breeding method utilizes foundation Guizhou black nanny goats and Nubia billy goats to bi-cross, first-class first Nubia billy goat-black nanny goat hybrid generation nanny goats chosen as the female parent and first-class Guizhou black billy goats chosen as the male parent backcross, first-class backcrossed filial generation billy goats and first-class nanny goats are chosen to cross to be fixed, and therefore the Puan black goat line with more stable genes is bred. By introducing the excellent genes of the Nubia goats, such as big build, high reproduction rate and fast growth, the breeding method ensures that the bred Puan black goat line has the advantages of big build, fast early growth and development, high reproduction rate, high meat productivity and the like besides the characteristics, such as high adaptability, high disease resistance and black clothing hair, of the Guizhou black goats.

Problems solved by technology

This breeding method needs to introduce two male parents of Nanjiang yellow sheep and Nubian goat from other places, so this breeding method has the following defects: first, there are many introduction channels, which can easily lead to various infectious diseases; Male wool color is pure yellow, and after crossing with Guizhou black goat ewe, its offspring hair color is yellow, so it is difficult to breed a new pure black black goat strain; third, due to the many introduction channels and long breeding period, it leads to the investment of manpower, Great material and financial resources

[0004] Therefore, existing above-mentioned black goat strain breeding method is still unsatisfactory
