Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific examples.

[0016] (1) Identify and evaluate Hu sheep and Dorper sheep according to the best linear unbiased prediction (BLUP). The identification and evaluation of ewes include age, body shape, weight, reproductive performance, identification and evaluation of rams The content includes age, body shape, appearance, and weight. Select 1,000 Hu sheep ewes aged 1-3 years old, good shape, pure white coat color, and normal reproductive ability from the Hu sheep production area, and select 45 Dorper rams. Only, to form a breeding group;

[0017] The specific criteria for the selection of Hu sheep ewes are: medium build, pure white coat color, no horns, narrow and long head, raised nose bridge, large drooping ears, slender neck, long and narrow body, straight back and waist, slightly drooping belly, flat and round tail , the tip of the tail is upturned, the limbs are thin and tall, and the body...

Abstract

The invention discloses a method for breeding a new Hu-sheep strain for high-quality meat. According to the method, hybridization and intercrossing are carried out with female Hu-sheep as female parents and male dorper sheep as male parents, and by means of the phenotypic selection method and the meat performance trait detection technology, the new Hu-sheep strain is bred through selection and propagation. The new Hu-sheep strain obtained through the breeding method keeps reproductive performance of the Hu-sheep and has good meat performance of the dorper sheep. The average lambing rate of the new Hu-sheep strain can be 260%, the average weight of six-month-old male sheep is 42.8 kg, the average weight of female sheep is 34.2 kg, the average slaughtering rate is 51.5%, and the pure meat percentage is 40%.

Description

technical field [0001] The invention relates to a method for cultivating a new strain of Hu sheep for high-quality meat, and belongs to the technical field of animals. 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. The live weight of adult Hu sheep ewes is about 54kg, and that of rams is about 58kg, which is far lower than other foreign sheep breeds. Contents of the invention [0003] The purpose of the method for cultivating new strains of Hu mutton of the present invention is to provide a ...
