Embodiment 1

[0019] A method for breeding fine varieties of Hu sheep, using Hu sheep ewes as female parents, Dorper sheep rams as male parents for hybridization and cross-crossing, and phenotypic selection combined with meat traits detection technology for breeding, Proliferate and obtain new strains for Hu mutton.

[0020] Specifically, the following steps are included:

[0021] (1) One month before the mating of Hu sheep, the ewes and rams were fed with special feed, which consisted of basic feed and special feed, and the weight of special feed was 2.5% of the weight of basic feed;

[0022] Among them, the metabolizable energy in the basic feed is 2200 kcal / kg, the content of crude protein is 15%, the content of protamine is 15%, and the content of crude fat is 3%;

[0023] The special feed is obtained by mixing α-linolenic acid, montmorillonite, and oligosaccharides in a weight ratio of 1:5:1.

[0024] The temperature of the breeding environment is controlled at 25°C on the 1st-7th da...

Embodiment 2

[0031] A method for breeding fine varieties of Hu sheep, using Hu sheep ewes as female parents, Dorper sheep rams as male parents for hybridization and cross-crossing, and phenotypic selection combined with meat traits detection technology for breeding, Proliferate and obtain new strains for Hu mutton.

[0032] Specifically, the following steps are included:

[0033] (1) One month before Hu sheep mating, the ewes and rams were fed with special feed, which consisted of basic feed and special feed, and the weight of special feed was 3% of the weight of basic feed;

[0034] Among them, the metabolizable energy in the basic feed is 2250 kcal / kg, the content of crude protein is 20%, the content of protamine is 20%, and the content of crude fat is 4%;

[0035] The special feed is obtained by mixing α-linolenic acid, montmorillonite, and oligosaccharides in a weight ratio of 1:5:1.

[0036] One month before mating, the breeding environment temperature is controlled at 28°C on the 1...

Abstract

The invention provides a quality variety breeding method to Huyang (a kind of sheep raised in Zhejiang province), including performing hybridization and inter mating by taking female Huyang as the female parent and taking male Dorper as the male parent, breeding and expanding propagation by combination of a phenotypic selection method and the meat production trait detection technology, so as to obtain the novel meat variety of Huyang. Before hybridization, the female sheep and the male sheep are fed for one month, which can improve reproductive performance of Huyang within a short time; Huyangcultivated by the method maintains excellent reproductive performance, and also has excellent meat production performance as the Dorper; its pure meat percentage can be up to 45%.

Description

technical field [0001] The invention relates to the field of Hu sheep breeding, in particular to a method for breeding fine varieties of Hu sheep. Background technique [0002] Hu sheep is one of the world's famous multi-lamb sheep breeds, and it is a first-class protected local livestock breed in my country. Originally produced in the Taihu Lake Basin in China, it has excellent traits such as early sexual maturity, estrus in four seasons, high fecundity, resistance to rough feeding, and heat and humidity resistance; its meat is delicious and tender, with less smell, but it has low carcass lean meat percentage, fatter meat, Disadvantages such as slow growth and development. Adult Hu sheep live sheep are lighter in weight, which is far different from other foreign sheep breeds. Contents of the invention [0003] Based on this, it is necessary to provide a method for breeding fine varieties of Hu sheep. [0004] A method for breeding fine varieties of Hu sheep, using Hu s...
