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
The present invention relates to the animal breeding technology field, particularly relate to utilization foremost Australian Merino (Australian Merino) fuzz type (Fine Merino) acerous strain and the local variety source of cultivating of Gansu Alpine fine wool sheep (Gansu Alpine Fine-wool sheep) in the world, carry out the breeding method of the acerous new lines of high mountain merino sheep.
Background technology
The developed countries such as Australia, France, Britain, New Zealand, the U.S. are not only high-quality wool, mutton big producing country, and focus on very much cultivation and the improvement of kind, cultivate many specializations, modernization new varieties, as the polyembryony direction: South African Mutton merino sheep, Bu Lula merino sheep etc.; Meat direction: South Africa merino sheep, German Muttoo Merino sheep etc.; Hair direction: Australian Merino (superfine type, fuzz type, middle wool type and strong wool type) etc., the acerous strain of Australian Merino fuzz type has good high-quality wool (wool fiber diameter 18.1～20.0 μ m), adult ram body weight 60.0～70.0kg, ewe 32.0～45.0kg; Adult ram clip 6.0～9.0kg, ewe 4.0～5.0kg; Wool length 7.0～10.0cm, 66～70 of fineness, scouring yield 55%～65%.The Gansu Alpine fine wool sheep ram weight average 98.24kg that grows up, ewe 48.85kg; The adult average 9.62kg of ram clip, ewe 5.14kg; The adult average wool length 10.94cm of ram, ewe 9.58cm; The adult average 19.98 μ m of ram wool fiber diameter, ewe 20.49 μ m; Wool intensity 7.06CN, scouring yield average 57.16%.
It is basically on 16 fine wool sheep kind bases of the 1950's～1980 oneself cultivation that China has approximately 3,000 ten thousand fine wool sheep at present, according to the market demand, successively by introducing Australian Merino, the South Africa merino sheep, the kind containing different fine wool sheep genes formed after the fine wool sheep inter breed crossings such as German Muttoo Merino sheep improvement, strain and hybrid sheep etc., they are in the quantity and the quality that improve China's fine wool and mutton, meet the about demand of 400,000 tons of high-quality fine wools (approximately 120,000 tons of domestic fine wool years in textile industry year, approximately 300,000 tons of import high-quality fine wool years) and the aspects such as supply of 480,000 tons of mutton play an important role, and cultivate and established solid foundation for the production domesticization of the acerous new lines of China's high mountain merino sheep.
Australia, France, Britain, New Zealand, the developed countries such as the U.S. are as the high-quality wool, mutton big producing country, intensive level improves constantly, and focuses on advanced science and technology in feed production, breeding and breed improvement, livestock and poultry standardization feeding and management, the application of the aspects such as animal product processing, pay attention to Grassland construction and grazing management, to pasture, implements scientific, modern management, have perfect wool, mutton production and sales system and sound social service system, and China still to take the small-scale individual family production of huge numbers of families be main production unit, cause the new technology acceptance level low, market circulation system imperfection, do not accomplish for a long time " excellent hair favorable rates ", lack the policy of supporting the fine wool sheep industry development in addition, cause the domestic fine wool sheep producer to lack the power of participation high-quality fine wool standardization large-scale production technology, be absorbed in the vicious circle of " the lower enthusiasm of Mao Zhiyue price difference lattice is lost ", thereby seriously restricted new varieties (being), the popularization of new technology, make the fine wool sheep industry for a long time low-level.Therefore, set up and take the agriculture and animal husbandry family as supplier, cooperative society, Animal Raising Zone and cultivation leading enterprise are the large-scale cultivation carrier, integrated antenatal, in product, postpartum kind sheep genetic improvement technology, the breeding multiplication technique, feeding and management becomes more meticulous, control and prevention of disease, wool standardized production and Quality Control Technology are set up the acerous new lines scale standard of Chinese high mountain merino sheep cultural technique system, conduct a research and be applicable to the acerous new lines cultivation of China's Qilian mountains Alpine-arctic Pastoral high mountain merino sheep, wool is stored up, circulation pattern and Related Technical Issues, the professional peasants and herdsmen of the acerous new lines industry of training high mountain merino sheep, rely on the acerous new lines production demonstration of stock breeding Establishing China's high mountain merino sheep, radiating base, promote the acerous new lines industrialized development of Chinese high mountain merino sheep.
Summary of the invention
The invention discloses the breeding method of the acerous strain of a kind of high mountain merino sheep, it is characterized in that seed selection acerous Australian Merino fuzz type stud ram and acerous Gansu Alpine fine wool sheep kind ewe constructional base group, hybridized the acerous first cross ewe that the physique of selecting and remain is good by the acerous Australian Merino fuzz type as male parent and the acerous Gansu Alpine fine wool sheep as female parent; Hybridized the individual secondary core group of setting up of acerous two generations hybridization ewe that the physique of selecting and remain is good with acerous first cross ewe and the acerous Australian Merino fuzz type stud ram of selecting and remain; With the acerous two generations hybridization ewe of selecting and remain, with acerous Australian Merino fuzz type stud ram, hybridized, the acerous three generations that the physique of selecting and remain is good is hybridized ram and the individual one-level core group of setting up of ewe again; The acerous two generations hybridization ewes of selecting and remain and acerous three generations are hybridized ewe and are hybridized the ram mating with the acerous three generations who selects and remain respectively, produce the acerous strain of high mountain merino sheep zero sheep from generation to generation, the acerous ram that the physique of selecting and remain is good and ewe individuality are set up core group again and are carried out locking and breed, and breed the offspring acerous stud ram that the physique of selecting and remain is good and plant ewe from its locking and adopt colony's subculture selection-breeding method to carry out the traversed by of at least 4 generations to fix, obtain the acerous strain of high mountain merino sheep.
The acerous new lines of high mountain merino sheep of this breeding method seed selection has that physique is tall and big, wool quality is excellent, grow fast, price of deed advantages of higher, be applicable to the Hexi Corridor In Gansu farming-pastoral region and Qilian mountains Alpine-arctic Pastoral is herded, stable breeding and drylot feeding are fattened, reduce the ewe feeding cost, improve the fanning economics of fine wool sheep, accelerate the fine wool sheep industrialization process.
The accompanying drawing explanation:
