Embodiment Construction

[0017] Dongbao black head sheep selection method is as follows:

[0018] Dongbao black head sheep breeding method is characterized in that the breeding method is:

[0019] A. Hybridization

[0020] The Boer goat is used as the male parent, and the Macheng black goat (provided by Wuhan Nongfu Shijia Breeding Co., Ltd.) is used as the female parent to carry out crossbreeding to obtain a hybrid generation;

[0021] B. Breeding

[0022] The selection criteria for the first generation of hybrids are as follows: the weight of the lamb at 6 months old is above 25 kg, the carcass weight is 12-15 kg, and the slaughter rate is above 48%; the adult ram is above 60 kg, and the ewe is above 45 kg; the average lambing rate is 180%~ 200%, the appearance is hair color with black head and white body;

[0023] C. Homogeneous matching

[0024] The first generation of hybrids that meet the selection criteria will be homogeneously matched to produce the second generation of hybrids;

Abstract

A breeding method of Dongbao blackhead sheep includes: subjecting Boer goats as male parents and Macheng black goats as female parents to hybridization, and performing cross breeding, positive assortative mating and population subculture breeding to obtain Dongbao blackhead sheep. The breeding method has the advantages that the Dongbao blackhead sheep bred by the method are uniform in appearance and shape, lambing rate is high, meat of the Dongbao blackhead sheep has no smell, and meat performance is high. The Dongbao blackhead sheep are significantly better than Macheng black goats in growth and meat performances, and are better than Boer goats in reproductive performance, crude feed tolerance, disease and stress resistance and the like.
