Embodiment Construction

[0015] A method for cultivating new strains of Yuxi fat-tailed mutton, comprising the following steps:

[0016] (1) Identify and evaluate Yuxi fat-tailed sheep, Bodedai sheep, and Dorper sheep. The identification and evaluation content of ewes includes appearance, size, age, weight, and reproductive performance. The identification and evaluation content of rams includes appearance Body shape, age, weight, 1,000 Yuxi fat-tailed ewes with good body shape, pure white coat color, normal reproductive ability, and age of 1-3 years were selected from the Western Henan fat-tailed sheep production area. Sheep rams and Dorper rams form a breeding group;

[0017] Specifically, the selection criteria for Yuxi fat-tailed ewes are: pure white coat, no horns, raised nose bridge, large drooping ears, open ribs, large and round belly, long and deep body, straight back and waist, and strong limbs , the hooves are firm and waxy, the fat tail is oval, the tip of the tail is close to the tail gro...

Abstract

The invention discloses a method for breeding a new strain for Yuxi fatty-tailed mutton. The method breeds the new strain for the Yuxi fatty-tailed mutton by performing three-way cross of Yuxi fatty-tailed sheep, Borderdale sheep and Dorper sheep and performing selective breeding and propagation with an individual phenotypic selection method and a trait detection technique for meat. The new strain for the Yuxi fatty-tailed mutton bred by the breeding method keeps the advantage of the Yuxi fatty-tailed sheep, and has excellent wool characteristic of the Borderdale sheep and ideal meat physical characteristic of the Dorper sheep. Compared with the Yuxi fatty-tailed sheep, the new strain has the advantages of high lambing rate which can reach over 150 percent, high growth and development, large physique (the weight of the adult male sheep can reach over 55 kilograms and the weight of the female sheep can reach over 40 kilograms), high meat yield, good meat quality and strong adaptability, and is suitable for barn feeding and development of fat lamb production.

Description

technical field [0001] The invention relates to a method for cultivating a new line of Yuxi fat-tailed mutton, belonging to the technical field of animal cultivation. Background technique [0002] The wool color of Yuxi fat tail is mainly white, the limbs are short and strong, the hooves are strong, and the fat tail is oval, hanging above the hock. Yuxi fat-tailed sheep has the advantages of resistance to rough feeding, strong disease resistance, heat resistance and fast fattening. In particular, this breed has strong climbing ability and is suitable for grazing on mountains. The lambing rate of Yuxi fat-tailed sheep is 107%, the lambing rate is low, and the body is small. The weight of adult rams is about 35 kg, and the weight of adult ewes is about 27 kg. However, the meat of Yuxi fat-tailed sheep is delicious, Delicate, unique flavor. [0003] In recent years, because the conservation and breeding work of Yuxi fat-tailed sheep has lagged behind, the productivity of this...
