Cultivating method of polled alpine merino strain

Abstract

The invention discloses a cultivating method of a polled alpine merino strain. Australia merino fine-wool rams and polled Gansu alpine fine-wool breeding ewes form a basic group, by means of hybridize and transverse fixup, the polled alpine merino strain is obtained. The polled alpine merino strain cultivated by the method has the advantages of big size, good wool quality, rapid growth, high feed efficiency and the like, and is adaptable to pasturing, captive breeding and stall-feeding and fattening in a farming-pastoral region in the Hexi Corridor in Gansu and in an alpine region on Qilian mountain; ewe feeding cost is reduced, economic benefit of cultivating fine-wool sheep is increased, and the process of fine-wool sheep industrialization is accelerated.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to the use of the world's most famous Australian Merino (Australian Merino) fine-haired (Fine Merino) hornless strain and Gansu Alpine Fine-wool sheep (Gansu Alpine Fine-wool sheep) local breeding Variety resources, the breeding method of a new line of Alpine Merino sheep without horns. Background technique [0002] Developed countries such as Australia, France, the United Kingdom, New Zealand, and the United States are not only major producers of high-quality wool and mutton, but also pay great attention to the cultivation and improvement of varieties, and have cultivated many specialized and modern new varieties, such as the direction of multiple births: South African meat Merino sheep , Burra Merino sheep, etc.; meat direction: South African Merino sheep, German Merino sheep, etc.; wool use direction: Australian Merino sheep (superfine, fine, medium and strong wool) ), e...

Problems solved by technology

[0004] Developed countries such as Australia, France, the United Kingdom, New Zealand, and the United States are major producers of high-quality wool and mutton, and their level of intensification has been continuously improved. It attaches great importance to pasture construction and grazing management, implements scientific and modern management on pastures, and has a complete wool and mutton production and sales system and a sound social service system. However, in my country, thousands of small-scale individual households still produce As the main production unit, the acceptance of new technologies is low, the market circulation system is not perfect, and the long-term failure to achieve "high-quality wool and high prices", coupled with the lack of policies to support the development of the fine-wool sheep industry, has led to the lack of participation of domestic fine-wool sheep producers in high-quality fine-wool sheep. The driving force of standardized wool production technology has fallen into a vicious circle of "the worse the wool quality, the lower the price, the loss of enthusiasm", which seriously restricts the promotion of new varieties (lines) and new technologies, and makes the fine-wool sheep industry hover at a low level for a long time
