Problems solved by technology

Studies have shown that the total reproductive capacity of binary hybrid sheep is increased by 2.1%, and the reproductive capacity of three-component hybrid sheep is increased by 14.9%. It can be seen that the way of multiple hybridization does have obvious advantages in improving a certain performance, but it is different from developed countries. Compared with other countries, my country started late in multivariate hybridization, and hybrid pigs are common, while multivariate hybridization for sheep is mainly based on binary hybridization, ternary hybridization is rare, and there are patents that also disclose related ternary hy

Embodiment 1

[0028] A production method of three-way hybrid mutton sheep, specifically adopting a natural mating method for hybridization, specifically:

[0029] Step 1: Using Australian White sheep (A), Dorper sheep (D), and Charolais sheep (X) as male parents, and Small-tailed Han sheep (H) as female parents, carry out breeding and crossing to obtain the F1 generation binary cross Offspring Aohan (AH), Duhan (DH), Xiahan (XH);

[0030] Step 2: Select Aushan ewes with fast growth, high feed conversion rate, strong physique, well-developed parts of the body, especially the reproductive organs, and obvious estrus performance during puberty from the F1 generation of binary hybrid offspring, and compare with Du Crossbreed Bo ram and Charolais ram to obtain F1 generation three-way hybrid offspring Du Aohan (DAH) and Xia Aohan (XAH);

[0031] The high-quality Duhan ewes were crossed with Australian white rams and Charolais rams respectively to obtain the F1 generation three-way hybrid offsprin...

Embodiment 2

[0086]The difference from Example 1 is that artificial insemination is used for crossbreeding, and the crossbreeding results are not different from those of natural mating methods, both of which are the best in all indicators of Aoxiahan Sanyuan crossbred mutton sheep.

[0087] The key technology of the three-element hybrid mutton sheep breeding obtained by crossing in different ways in the above examples 1-2 is: early supplementary feeding of lambs, rapid fattening technology of lambs after weaning, full house feeding TMR feeding and epidemic prevention and control of 4 meat sheep The integrated application of key technologies for intensive farming reduces the production cost of sheep farms and improves production efficiency. At present, the integrated application of these four key technologies for the intensive breeding of meat sheep is the first in China, and the immunization program is created by the inventor himself. The four key technologies for meat sheep intensive farm...

Abstract

The invention discloses a ternary hybrid mutton sheep production method, which comprises: 1, setting a small tailed han sheep pure breeding group as a control group, setting an experiment group, adopting small tailed han sheep as a female parent, adopting Australian white sheep, Dorper sheep and Charolai sheep as male parents, and carrying out hybridization to produce three binary hybrid mutton sheep; 2, selecting ewes of high-quality binary hybrid mutton sheep as female parents, and hybridizing the female parents with Australian white sheep, Dorper sheep and Charolai sheep respectively to generate six kinds of ternary hybrid mutton sheep; and 3, screening out an optimal hybridization combination from the six ternary hybridization combinations through production performance analysis and comparative study. The Australian summer cold ternary hybrid mutton sheep finally obtained by the method has the advantages of high growth speed, large slaughtering weight, high slaughtering rate, low feed conversion ratio and the like, a new method is provided for quickly producing mutton sheep in batches, and the requirements of modern people on high-quality mutton can be met in time.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a method for producing three-way hybrid mutton sheep. Background technique [0002] Small-tailed Han sheep are produced in southern Hebei, eastern and northeastern Henan, southern Shandong, northern Anhui, and northern Jiangsu. They have early maturity, fast growth and development in the early stage, tall physique, good meat quality, estrus in four seasons, strong fecundity, and stable genetics. and other characteristics. Although Small-tailed Han sheep have strong reproductive ability and many lambs, the current breeding management of ewes is not scientific and meticulous, resulting in longer non-production days of ewes, increasing production costs, reducing breeding benefits, and at the same time, the meat production rate is relatively low , not suitable for use as meat sheep. [0003] At present, in order to improve the meat production performance and mutton quality ...
