Method for breeding red-head mutton goat new strain

The invention relates to a method for breeding a red-head mutton goat new strain capable of improving the growing development speed and mutton yield, relating to livestock improvement. The method comprises the following steps: (1) pairing a male Boer goat and a female Huai goat to give birth to F1 hybrid of the Boer goat and the Huai goat; (2) pairing the male Boer goat and a female local milk goat to give birth to F1 hybrid of the Boer goat and the milk goat; (3) pairing larger bodies in male Boer-Huai F1 hybrid goats and female Boer-milk F1 hybrid goat; and (4) hybridizing the male Boer goat and a F2 female born hybrid goat, continuously grading the second generation, selecting the hybrid progeny with the red head characteristic in each hybridizing process, fixing cross breeding after the F4 generation, and breeding and expanding population to ensure that the characteristic of the red head goat in the group can be stably maintained. In the method, based on the excellent breeding characters of the Huai goat
