Problems solved by technology

In this way of raising sheep, since the price of good breeds of meat sheep imported from abroad is generally 4-6 times that of local breeds of rams, so sheep farmers pay their own funds to buy them, and users rarely buy them.

Embodiment

[0015] Taking the use of different breeds of excellent meat sheep hybrids introduced in our country to improve local sheep as an example, the following steps are included in turn:

[0016] (1) According to 5 sheep raising divisions: the first district selects Suffolk mutton sheep as the male parent, the second district selects the Deroumei mutton sheep as the male parent, the third district selects the hornless Dorset mutton sheep as the male parent, and the fourth district selects the Deroumei mutton sheep as the male parent. Select Daxo mutton sheep as the male parent, and choose Charolais mutton sheep as the male parent in the fifth district;

[0017] (2) The first district is divided according to 5 core sheep raising households: the first household raises the No. 1 Suffolk beef ram, the second household raises the No. The No. 4 Suffolk meat ram, the fourth household has a No. 4 Suffolk meat ram, and the fifth family has a No. 5 Suffolk meat ram.

Abstract

The invention discloses a hybridization breeding method for high quality mutton sheep, which mainly solves the problem of hybridization breeding technique and method for mutton sheep in rural cooperative development. The main point of the technical proposal is that: in the scope of rural sheep producers of more than 50, five sheep raising areas are divided, and five core sheep farmers are chosen from each sheep raising area; in each year, each stud ram used by a sheep farmer for a breeding period is mutually shifted among the five core sheep farmers; in each five year, an excellent descendant stud ram chosen from each sheep raising area is shifted among the five sheep raising areas for using for one time. The hybridization breeding method is mainly aimed at reforming common flocks of sheep with low meat production performance into sheep flocks with high meat production in a certain scope within five years. Determination of hybrid advantages of 125 hybridized combinations of five excellent mutton sheep species can be done within 10 years in a certain range.

Description

Technical field: [0001] The invention relates to a method for hybrid breeding of high-quality mutton sheep Background technique: [0002] Vigorously develop the mutton sheep industry, which is the direction that our country and countries in the world will strive for in raising sheep in the future. At present, the main way of raising sheep in my country is to raise sheep of local breeds with low meat production performance in rural areas with thousands of households, small-scale and scattered. Under this kind of sheep raising method, since the price of good breeds of meat sheep imported from abroad is generally 4-6 times that of local breeds of rams, there are very few sheep farmers who buy them with their own funds. This has not only seriously affected the quantity and quality of our country's improvement of local breeds of sheep by crossbreeding fine breeds of mutton sheep imported from abroad, but also seriously delayed the establishment and improvement of our country's m...
