Embodiment Construction

[0019] In order to make the content of the present invention more obvious and understandable, the present invention will be described in detail below in conjunction with specific embodiments.

[0020] A method for cultivating a new strain of small-tailed Han mutton, using small-tailed Han sheep as the female parent and white-headed Suffolk sheep as the male parent to carry out cross-breeding to produce second-generation flocks to obtain second-generation Sahan flocks; The first-generation Du Han sheep produced by crossbreeding the Bo sheep breed with the small-tailed Han sheep is used as the female parent, and the Australian white sheep is used as the terminal male parent to produce the second-generation Auduhan sheep; Hybridization of sheep to produce a new strain of Sadu Aohan, and finally through optimal combination and cross-cross fixation, a new strain for small-tailed Han mutton was bred.

[0021] Further, the method for cultivating a new strain of Xiaoweihan mutton comp...

Abstract

The invention discloses a breeding method of a new meat-type strain of small tailed han sheep. The small tailed han sheep are used as female parents, and white head Suffolk sheep are used as male parents for introductive hybridization to produce a second generation sheep flock to obtain a Sahan second generation sheep flock; then, first generation Duhan sheep produced by hybridizing white head Dorper sheep varieties with the small tailed han sheep are used as female patients; Australian white sheep are used as terminal male parents for producing Aoduhan second generation through hybridization; then, the sahan second generation female sheep are hybridized with the Aoduhan second generation male sheep to produce Saduaohan new strains; finally, through optimization combination and cross hybridization fixation, the new strain of meat-type small tailed han sheep is obtained through breeding. The obtained new strain has the advantages that the growth and development speed is high; both the meat and milk purposes can be achieved; the body shape is good; the hair in the whole body is white; the applicability is high; the polyembryony property of the small tailed han sheep is realized; the lambing percentage of the female sheep is 200 percent or above; the body weight of the adult male sheep reaches 100kg or higher; the body weight of the adult female sheep reaches 70kg or higher.
