Embodiment Construction

[0010] The method for cultivating new strains of local sheep in Linzhou described above uses Linzhou local sheep as the female parent, and small-tailed Han sheep, Dorper sheep, and Charolais sheep as male parents to carry out three-way hybridization to obtain a new strain of local sheep in Linzhou. . Its steps are as follows:

[0011] (1) Crossbreed with Linzhou local sheep as the female parent and Small-tailed Han sheep as the male parent to obtain the F1 generation, and select excellent ewes from the F1 generation;

[0012] (2) Crossbreed the excellent ewes of the F1 generation and the male parent of Dorper sheep to obtain the F2 generation, and select the excellent ewes from the F2 generation;

[0013] (3) A new strain of local sheep in Linzhou was obtained by crossing the F2 generation excellent ewes as the female parent and the Charolais sheep as the male parent.

Abstract

The invention discloses a breeding method of Linzhou local sheep new strains, which takes a Linzhou local sheep as a female parent, takes a small tailed Han sheep, a Dorper sheep and a Charolais as male parents to carry out three way cross, so the Linzhou local sheep new strains are obtained. Because the Linzhou local sheep is taken as the female parent, the small tailed Han sheep, the Dorper sheep and the Charolais are taken as the male parents to carry out the three way cross, so the Linzhou local sheep new strains are obtained and are heavier than the local sheep by over 12%, the price of feed is improved by more than 10%, the meat performance is improved by more than 26%, and the meat quality is tender.

Description

technical field [0001] The invention relates to a method for cultivating sheep, in particular to a method for cultivating new strains of local sheep in Linzhou. Background technique [0002] Mutton has the characteristics of lean meat, rich nutrition, less fat, low cholesterol, tender and juicy, and easy to digest. The sheep grow fast, the feed remuneration is high, the production cost is low, and the product sales price is high. Due to the promising market prospects, my country's sheep production has developed rapidly in recent years, but there is still a large gap compared with countries with more developed sheep farming in the world. The pay is low and the slaughter rate is not high. Linzhou local sheep are small in size, slow in growth and development, and poor in meat performance. However, sheep from other places are not suitable for the local climate in Linzhou and cannot be widely bred. Contents of the invention [0003] The technical problem to be solved by the ...
