Abstract

The invention mainly relates to a highly-productive mutton sheep new strain breeding method. According to the method, Hu sheep are used as female parents, small tailed Han sheep are used as male parents, and the Hu sheep and the small tailed Han sheep are hybridized to obtain first filial generation Hu-Han sheep; first filial generation Hu-Han ewes are used as female parents, Dorper sheep are used as male parents, and the first filial generation Hu-Han ewes and the Dorper sheep are hybridized to obtain second filial generation Hu-Han-Dorper sheep; then, second filial generation Hu-Han-Dorper ewes and Dorper rams are hybridized to obtain third filial generation sheep; the third filial generation sheep are crossbred fixedly for three generations to breed a highly-productive mutton sheep new strain. The sheep new strain obtained according to the highly-productive mutton sheep new strain breeding method is large in physique, fast in growth and development and high in mutton production rate, and has a pure black head; the weight of a grown ram reaches above 90 kg, the weight of a grown ewe reaches above 60 kg, and the lambing rate reaches above 200 %; the sheep new strain is strong in adaptability and suitable for drylot feeding and fat lamb production development. The highly-productive mutton sheep new strain has the advantages of strong adaptability and high lambing rate of the Hu sheep and the small tailed Han sheep and further has the advantages of being enlarged in physique, fast in growth and development, good in table purpose body type, enhanced in mutton productivity, and good in mutton quality.
