Embodiment

[0032] Example, house feeding breeding mode of "Du Huhan" three-way hybrid sheep

[0033] Breeding location: Inner Mongolia Hailaer Land Reclamation Group Xier Tala Nong Ranch

[0034] Breeding time: 2011 to 2015

[0035] Specific housing breeding mode:

[0036] 1. Collect the semen of small-tailed Han sheep rams, inseminate Hulunbuir ewes, and then put them into small-tailed Han sheep rams for mopping, and obtain Huhan sheep (binary hybrid sheep);

[0037] 2. Collect the semen of Dorper sheep rams, inseminate Huhan sheep ewes, and then put them into Dorper sheep rams for mopping, and obtain Du Huhan sheep (three-way hybrid sheep).

[0038] Parity, average daily gain, daily roughage intake, adaptability, prevalence, meat quality, birth weight, 3 Month-old weight, 6-month-old weight, slaughter rate and carcass weight were investigated and counted.

[0039] Some results are shown in Table 1. The results show that the Huhan sheep obtained by using this breeding mode are prol...

Abstract

The invention discloses a farming model of three-way cross-bred sheep. The farming model of three-way cross-bred sheep comprises the steps: (1) hybridizing Hulunbeier sheep and small-tailed Han sheep to obtain Hu-Han sheep; (2) hybridizing the Hu-Han sheep with Dorper sheep to obtain Dorper-Hu-Han sheep. Experimental results show that by utilizing the farming model of three-way cross-bred sheep, the Hu-Han sheep has high productivity and prolificacy, inherits high reproductivity of the small-tailed Han sheep and can provide weaned lambs for Dorper-Hu-Han sheep. The Dorper-Hu-Han sheep inherits not only the features of Hulunbeier sheep, such as high meat quality, good tolerance to crude feed, strong adaptability and high disease resistance, but also the features of the Dorper sheep, such as high weight-gaining speed. The numbers of pure bred sheep, two-way cross-bred sheep and three-way cross-bred sheep are allocated reasonably, and the farming model of 'three births in two years and two lambs per birth' is achieved. Meanwhile, grassland bearing capacity is lowered and a grassland ecology is protected. The farming model of three-way cross-bred sheep has important value.

Description

technical field [0001] The invention belongs to the field of animal husbandry and breeding, and relates to a breeding mode of a three-way hybrid sheep, in particular to the breeding of "Du Huhan" three-way cross-breed sheep which are hybridized and bred by three fine varieties of Hulunbuir sheep, small-tailed Han sheep and Dorper sheep model. Background technique [0002] Hulunbuir sheep, small-tailed Han sheep and Dorper sheep are three important breeds in production, each with different characteristics. Hulunbeier sheep has the advantages of resistance to rough feeding, strong adaptability, strong disease resistance and no smell of mutton, but its reproductive performance and meat production performance are both low. Small-tailed Han sheep have high reproductive performance, but low meat production performance and poor meat processing. Dorper sheep grow rapidly and have high meat production performance, but low reproductive performance. How to use different breeds of sh...
