Problems solved by technology

Among them, the hybrid sheep breed of Euler Tibetan sheep and Small-tailed Han sheep has been recognized as a relatively successful breed in recent years. This breed has a relatively good growth rate, but there are still some shortcomings, mainly in the unsatisfactory meat production, and the The low content of ingredients leads to poor meat quality and flavor, which affects the taste of consumers and the market is not good

Embodiment 1

[0012] Embodiment 1: Utilize hornless Dorset ram and Jinzhong ewe to carry out crossbreeding, the first generation hornless Dorset ram of hybrid sheep and ewe continue to hybridize, the ewe in the second generation hybrid sheep again It is obtained by crossing with Hornless Dorset ram, and crossing the third-generation hybrid ram with Texel ewe.

Embodiment 2

[0013] Embodiment 2: Utilize hornless Dorset ram and Jinzhong ewe to carry out crossbreeding, the first generation hornless Dorset ram of hybrid sheep and ewe continue to interbreed, the ewe in the second generation hybrid sheep again It is obtained by crossing with Hornless Dorset ram, and the third-generation hybrid ewe and Texel ram.

[0014] Take 10 Songyu sheep obtained in Examples 1 and 2 respectively, count their growth rate and size, and calculate the average value (Table 1, 2); then slaughter them, and take the slaughter results of 6-month-old lambs to determine the average value (Table 3 ), and finally detect the nutrient composition and various amino acid contents in the obtained meat (Table 4, 5).

[0015] As a comparison, the indicators of each period were compared with the crossbred sheep of Euler Tibetan sheep and Small-tailed Han sheep (abbreviated as Tibetan × Han lamb), which are currently recognized as relatively good, and the purebred small-tailed Han sheep...

Abstract

The invention discloses a sheep hybridization breeding method. The method comprises the following steps of hybridizing poll Dorset rams with ewes to obtain F1-generation hybrid poll Dorset sheep; hybridizing F1-generation hybrid poll Dorset rams with ewes to obtain F2-generation hybrid poll Dorset sheep; hybridizing F2-generation hybrid poll Dorset ewes with poll Dorset rams to obtain F3-generation hybrid poll Dorset sheep; hybridizing F3-generation poll Dorset sheep with Texel sheep to obtain Songyu sheep. Songyu sheep obtained through the sheep hybridization breeding method are more nutritious than ordinary sheep and meanwhile provide higher mutton yield than the ordinary sheep.

Description

technical field [0001] The invention relates to the technical field of animal hybridization, in particular to a hybrid breeding method for a new breed of hornless Dorset hybrid sheep. Background technique [0002] In order to improve indicators such as meat yield and nutritional content, breeders have extensively studied the method of improving sheep quality through crossbreeding for many years. Among them, the hybrid sheep breed of Euler Tibetan sheep and Small-tailed Han sheep has been recognized as a relatively successful breed in recent years. This breed has a relatively good growth rate, but there are still some shortcomings, mainly in the unsatisfactory meat production, and the The low content of ingredients leads to poor meat quality and flavor, which affects the taste of consumers, and the market is not good. [0003] Therefore, there is still a need in the art to obtain better hybrid sheep breeds through new hybridization methods. Contents of the invention [00...
