Abstract

The invention discloses a black goat breeding method which includes the steps: S1 selecting healthy Boer bill goats and Wushan local nanny black goats and performing hybridization to obtain F1-generation crossbred Boer goats; S2 cross-breeding nanny goats in the F1-generation crossbred Boer goats with Wushan local black bill goats to obtain F2-generation crossbred Boer goats; S3 back-crossing bill goats in the F2-generation crossbred Boer goats with Wushan local nanny goats to obtain F3-generation crossbred Boer goats; S4 breeding the F3-generation crossbred Boer goats in a grouped manner according to the breeding standard of selecting goats with hair colors the most approximate to black in the current generation to obtain Fn-generation crossbred Boer goats with completely black hair colors; S5 crossly fixing the Fn-generation crossbred Boer goats to obtain black goat new species. The selection standard of the nanny goats in the F1-generation crossbred Boer goats is a flower hair color. The selection standard of the nanny goats in the F2-generation crossbred Boer goats is a brown hair color. The bred new black goat species have excellent reproductive performances and meat performances, and the disease resistance of the bred new black goat species is stronger than that of the Wushan local black goats.
