Method for breeding high-quality fine-wool sheep adaptable to high, cold and draught area

Abstract

The invention discloses a method for breeding high-quality fine-wool type mutton-wool sheep adaptable to a high, cold and draught area. The method comprises the steps that Gansu alpine fine-wool sheep are used as the female parent and fine or ultra-fine Australia merinos are used as the male parent, athwart cross fixation is conducted on a secondary-hybridization or ternary-hybridization ideal type ram and a secondary-hybridization or ternary-hybridization ideal type ideal type ewe by means of grading hybridization, and the target sheep variety is obtained after four generations and breeding improvement. The high-quality fine-wool alpine merinos adaptable to the high, cold and draught area obtained with the breeding method is excellent in wool quality, the wool is white and of a scopula structure, the closing property is good, the wool is neat and even, high in density, good in luster, white or milk white in sticky sweat, normal in bending performance, and high in stress resistance. The high-quality fine-wool alpine merinos are adaptable to the severe ecological condition of the high-altitude cold and draught mountainous area and a four-season grazing and long-distance transferring feeding and management mode.

Description

technical field [0001] The invention relates to a breeding method for a new breed of sheep, in particular to a method for breeding wool and meat dual-purpose sheep capable of producing high-quality fine wool and adapting to alpine and arid regions. Background technique [0002] The world's wool production is mainly concentrated in Oceania and Asia, and the total wool production of the two continents accounts for 70% of the world. In addition, Europe, Africa and South America also have a certain amount of wool production. Australia, China, New Zealand, South Africa, Argentina, and Uruguay are the major wool producing countries in the world. The latest statistics released by the International Wool Textile Organization show that wool production has continued to decline in recent years, and the annual net wool production is about 1 million tons. The tight supply and demand of wool in the world is difficult to change in the short term. my country's wool production, especially fi...

Problems solved by technology

However, there is still a certain gap compared with the production level of Australian Merino sheep, which is mainly reflected in the following: but compared with Australian Merino sheep, Gansu alpine fine wool sheep have shorter wool (6.0-7.0cm) and thicker wool (60-7cm). 64 pieces), low net wool rate (30%~40%), short abdominal hair (3.0~5.0cm), poor closure of hair clumps and small bends, yellowish oily sweat, etc., are not suitable for the needs of modern high-end worsted textiles
