Description
Technical field
The present invention relates to Conservation of Genetic Resources technical field, especially a kind of protecting method of Yunnan peak ox.
Background technique
Yunnan peak ox also known as Yunnan Zebu Cattle, major production areas be the Ruili County of Dai-Jingpo Autonomous Prefecture of Dehong, Luxi county,
Wanding town, the county Cang Yuan, the county Geng Ma, Zhenkang County of Lincang Prefecture, Mengla County, the Jinghong County of Dai Autonomous Prefecture of Xishuangbanna, Simao
The counties such as billows deep blue, Xi Meng and the Meng Lian in area.Producing region is located between 21 ° 9 '~29 ° 16 ' of north latitude, 97 ° 39 '~106 ° 12 ' of east longitude.
Yunnan peak ox and Cattle macroscopic features, three-dimensional-structure, hair color, it is angular and in terms of have notable difference.
Yunnan peak ox modern world carry out ox improvement in become European and American countries improvement cow or stocker it is important
Genetic resources.Nowadays, conscientious systematic research is not carried out to Yunnan peak ox due to various reasons, so that this important poultry
It has not drawn attention since kind resource long-term, in addition without implementing preservable measures, causes the number of animals raised of this kind sharply to decline, be on the point of
Face extinction.Therefore, the Yunnan peak producing region Niu Jizhong establish with perfect conservation base, take effectively measure, in a planned way into
Row breeding improves, and further carries out to the ox kind matter and the research utilized, is the development and quality of Yunnan peak ox quantity
Improving and providing scientific basis has been the task of top priority.
Summary of the invention
To solve problems of the prior art, the present invention provides a kind of protecting method of Yunnan peak ox.
The technical solution adopted by the present invention is that:
A kind of protecting method of Yunnan peak ox, comprising the following steps:
A, cows are generally investigated: numbered at the beginning of picking out the peak Niu Yici progress of Yunnan peak cattle breeds feature from Yunnan,
Blood collection, DNA extraction, DNA detection, data statistics, comparing and individual apolegamy optimization.
B, it selected population: is cultivated from the peak Niu Jinhang of the Yunnan peak cattle breeds feature after individual optimization, is bred as adult
The male peak ox of kind and the female peak ox of adult kind, kind of the public affairs peak Niu Tichong that grows up are 350kg-400kg, an adult kind mother peak Niu Tichong
For 300kg-350kg, then by the cultivation of series, select, eliminate, cultivating again, select and meet Yunnan peak cattle breeds feature
Population；
C, establish underlying group: selection meets the adult kind public affairs peak ox of Yunnan peak cattle breeds feature, and with relationship independence
The public peak Niu Zuowei group of adult kind an effective content, set up in the male and female ratio of 1:4 into family, avoided in each family complete
Compatriot or half sibs assemble, and zero generation population of composition is bred；
D, subculture is bred: being numbered to the nascent peak ox bred out in c, is carried out mixed group's raising after carrying out pedigree record, often
One generation sets up new family cultivation in the 2-3 year；
E, germplasm monitors: during conservation, expanding numerous, by the variety standard of related breeding or the specific germplasm of excellent variety
Standard periodically carries out kind of a quality detection to breeding, underproof to eliminate in time, to ensure the Optimality of germplasm.
F, prolong generation breeding: repeating c to e.
The protecting method of Yunnan peak ox of the invention, mainly by including generaI investigation cows, selected population, establishing basis
Group, germplasm monitoring, prolongs a series of technical measures such as generation breeding at subculture breeding, with the kind for the Yunnan peak ox for ensuring to select
Matter is good, does not degenerate, and increases；By individual apolegamy optimization, the means that selected population is eliminated and germplasm monitoring is superseded, both
It is able to achieve the conservation to Yunnan peak Cattle genetic resources, and the effect that can be increased economic efficiency.
Preferably, the breeding region of the Yunnan peak ox underlying group should be in the original area of Yunnan peak ox, and keep
It is consistent with original area's natural ecological condition.Conservation seeks to save the gene and gene that all are associated with specific ecological condition
Combined system, and Yunnan peak ox originates in the historical conditions in area and ecological environment must be that meet Yunnan peak ox specifically ecological
Condition, therefore, the present invention by the breeding region of Yunnan peak ox underlying group be set in Yunnan peak ox originate in area in, and keep with
It is consistent to originate in area's natural ecological condition, facilitates the reservation to Yunnan peak ox.
Preferably, the adult kind public affairs peak Niu Tichong is 350kg, and adult kind mother peak Niu Tichong is 300kg.Such choosing
The nascent peak Niu Tichong brought out is up to standard, can not only continue the excellent variety for saving Yunnan peak ox, but also in certain journey
The economic benefit of Yunnan peak ox is increased on degree.
Preferably, the adult kind public affairs peak Niu Tichong is 375kg, and adult kind mother peak Niu Tichong is 325kg.Such choosing
It is up to standard to bring out the nascent peak Niu Tichong come, raising survival rate is higher, can not only continue the excellent product for saving Yunnan peak ox
Kind, and the economic benefit of Yunnan peak ox is increased to a certain extent.
Preferably, the adult kind public affairs peak Niu Tichong is 400kg, and adult kind mother peak Niu Tichong is 350kg.Such choosing
It is up to standard to bring out the nascent peak Niu Tichong come, raising survival rate is higher, and the peak obstinacy maturation bred out is more early, and quantity can
It sees, can not only continue the excellent variety for saving Yunnan peak ox, but also increase the warp of Yunnan peak ox to a certain extent
Ji benefit.
The beneficial effects of the present invention are:
1, the protecting method of Yunnan peak ox of the invention, mainly by including generaI investigation cows, selected population, establishing base
Plinth group, germplasm monitoring, prolongs a series of technical measures such as generation breeding at subculture breeding, with the Yunnan peak ox that ensures to select
Germplasm is good, does not degenerate, and increases；It is eliminated by individual apolegamy optimization, selected population and germplasm monitors superseded means,
Not only the conservation to Yunnan peak Cattle genetic resources, but also the effect that can be increased economic efficiency be able to achieve.
2, conservation seeks to save the gene and assortment of genes system that all are associated with specific ecological condition, and Yunnan is high
Peak ox originates in the historical conditions in area and ecological environment must meet the specific ecological condition of Yunnan peak ox, therefore, the present invention
The breeding region of Yunnan peak ox underlying group is set in Yunnan peak ox to originate in area, and is kept and original area's natural ecology item
Part is consistent, facilitates the reservation to Yunnan peak ox.
3, the adult kind public affairs peak Niu Tichong is 350kg, and adult kind mother peak Niu Tichong is 300kg.It is such to select
The nascent peak Niu Tichong come is up to standard, can not only continue the excellent variety for saving Yunnan peak ox, but also to a certain extent
Increase the economic benefit of Yunnan peak ox.
4, the adult kind public affairs peak Niu Tichong is 375kg, and adult kind mother peak Niu Tichong is 325kg.It is such to select
The nascent peak Niu Tichong come is up to standard, and raising survival rate is higher, can not only continue the excellent variety for saving Yunnan peak ox, and
And the economic benefit of Yunnan peak ox is increased to a certain extent.
5, the adult kind public affairs peak Niu Tichong is 400kg, and adult kind mother peak Niu Tichong is 350kg.It is such to select
The nascent peak Niu Tichong come is up to standard, and raising survival rate is higher, and the peak obstinacy maturation bred out is more early, a considerable number of, no
It can only continue to save the excellent variety of Yunnan peak ox, and the economy for increasing Yunnan peak ox to a certain extent is imitated
Benefit.
