Description
Technical field
The present invention relates to poultry kind improving technology fields, and in particular to a kind of double cross method improving quality of mutton and yield.
Background technology
China is mutton production big country, 10 years especially nearly, has been developing progressively as maximum mutton production state in the world,
Rough estimates, China's sheep amount of delivering for sale reaches 287,410,000 within 2014, occupies first place in the world, and 4,410,000 tons of Mutton yield in 2015 accounts for
The 5.1% of meat total output.However, the quality due to mutton is not high, limited amount, in addition factors shadows such as processing and packing are bad
It rings, it is not strong in the competitiveness of international mutton in the market.Its reason：First, due to populous, mutton cannot be satisfied full season
Balance between supply and demand；Two are a lack of special meat breed and matching system, such as feeding management, product processing and the marketing
Deng, it is to come from the residual and superseded kind of the old and the weak that mutton, which is supplied with considerable part, and international standard is also not achieved in some lamb quality, influence
To the competition in market, and constrain the production development of mutton sheep.
Invention content
(1) the technical issues of solving
It in view of the deficiencies of the prior art, can be with the present invention provides a kind of double cross method improving quality of mutton and yield
It effectively improves the quality of mutton and increases the yield of mutton, and then to adapt to the needs of international and domestic market.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs：
A kind of double cross method improving quality of mutton and yield, includes the following steps：
(1) the breeding mutton sheep Poll Dorset of introduction, Bo get Dai frozen embryo carry out embryo's shifting by receptor of domestic mutton sheep
It plants, after lambing, by kind and gender subfield, summer and autumn whole day is herded, the feeding of winter-spring season sheep hurdle, sexal maturity after 220-250d, i.e.,
It can carry out first cross；
(2) first cross is divided to two groups of progress, and one group is hybridized for Poll Dorset with domestic mutton sheep, and another group obtains for wave
In generation, is hybridized with domestic mutton sheep, and two groups are all made of In vitro fertilization-embryo transplantation technology, and embryo is carried out by receptor of domestic mutton sheep
Tire is transplanted, and obtains the produced two groups of sheep of first cross only；
(3) the produced two groups of sheep of first cross only, are grouped subfield, and same summer and autumn whole day is herded, the feeding of winter-spring season sheep hurdle,
Observation is cultivated at any time, it is observed that after sexal maturity, two groups of sheep are only carrying out hybridization pairing, equally use In vitro fertilization-embryo transplantation
Technology carries out embryo transfer by receptor of domestic mutton sheep, obtains the produced sheep of two generations hybridization only, normal to feed, and cultivates sight at any time
It examines, eliminates low performance and Genomic instability individual, obtain outstanding hybrid individual.
Preferably, the domestic mutton sheep can be Small-fat-tail sheep, Matou goats, Guizhou White Goat, Lanzhou fat-tailed sheep, Wu Zhu
Mu Qinyang.
Preferably, Poll Dorset code name is A, and it is B from generation to generation number that wave, which obtains, and domestic mutton sheep code name is C.
Preferably, the produced two groups of sheep of first cross are only AC and BC.
Preferably, it is AC × BC that two generations, which hybridized produced sheep only,.
Preferably, embryo transfer with hybridize domestic mutton sheep type used must be consistent.
Preferably, when Poll Dorset is hybridized with domestic mutton sheep, Poll Dorset is male parent, and domestic mutton sheep is mother
This；When Bo get Dai is hybridized with domestic mutton sheep, wave is obtained on behalf of female parent, and domestic mutton sheep is male parent.
(3) advantageous effect
The present invention provides a kind of double cross methods improving quality of mutton and yield, have the advantages that：
The present invention can integrate the advantages of participating in Hybrid, to sheep growth and development by the double cross of three kinds
Raising effect is apparent, and meat production is more than to participate in the excellent Mutton Sheep of original kind of hybridization, and its live-weight, carcass weight, net
Meat weight and neat percentage four indices all have prodigious raising, and outstanding hybrid individual therein is also compared with Mongolian sheep
Show that disease resistance is strong, the excellent characteristic of strong environmental adaptability can meet the needs of international and domestic market, be worth quilt
It is a wide range of to promote.
