Abstract
The invention discloses a kind of Taihu pigs selection, belong to animal reproduction breeding field, by the rice pig of Taihu Lake basin, prunus mume (sieb.) sieb.et zucc. mountain pig, Fengjing pig and Erhualian are carried out reciprocal crosses, expand heterosis, hybrid vigor, set up and stablize prunus mume (sieb.) sieb.et zucc. rice two maple line of breeding, select more excellent reproductive performance and the stable kind of heritability.Prunus mume (sieb.) sieb.et zucc. rice two maple Taihu pigs and the prunus mume (sieb.) sieb.et zucc. mountain pigs that the method obtains etc. are without compared with the Taihu pigs of hybridization; total yield coefficient, number born alive are significantly improved; overcome the defect that current Taihu pigs locking selfing brings; protect the heritability of China's Native Pig reproductive performance, and provide special high-quality female parent breed system for pig Reproduction industry.
Description
Technical field
The present invention relates to animal reproduction breeding field, relate in particular to a kind of Taihu pigs selection.
Background technology
The method of current domestic cultivation pig variety mostly is the pig kind that Introduced From Abroad growth promoter is fast, the price of deed is high and works as with China
Ground mixing breed；Or carry out this breed breeding of land race.Taihu pigs is the pig kind that litter size is most in the world, often
As the female parent of hybridization, principal item includes prunus mume (sieb.) sieb.et zucc. mountain pig, Fengjing pig, Erhualian etc..Long-term miscellaneous with external introduced variety
Handing over, the resistance of cultivation kind, adaptability can be made to decline, piglet is liable to illness；And utilize this breed breeding, it is bred as product
The cycle of kind is long, and in Breeding Process, recessive gene easily overlaps, and it is healthy that kind is cultivated in impact.
From the point of view of long term growth, the pig kind of high reproductive performance local to China carries out breeding and optimization is very must now
Want, thus for providing more favourable condition with other pig kind outbreedinges.
Summary of the invention
Goal of the invention: it is an object of the invention to provide a kind of number born alive, crude feed tolerance ability more excellent by crossbreed means
Elegant local maternal new varieties.
Technical scheme: in order to realize foregoing invention purpose, a kind of Taihu pigs selection of the present invention includes:
(1) by rice pig and Mei Shan pig reciprocal crosses, rice after the rainy season is bred paternal and maternal；By positive and negative to Fengjing pig and Erhualian
Hand over, breed two maples paternal and maternal；By Mei meter and the reciprocal crosses paternal, maternal of two maples, producing meter Er Feng tetra-after the rainy season is
Offspring；
(2) set up prunus mume (sieb.) sieb.et zucc. rice two maple and cultivate system, start selection-breeding from generation to generation from zero, the offspring consistent based on hair color and reproductive capacity table
From generation to generation, group expanding is promoted, it is thus achieved that the prunus mume (sieb.) sieb.et zucc. rice two maple Taihu pigs of genetic stability in existing selection-breeding.
The parental generation of aforementioned four kind, rice pig, Mei Shan, Fengjing pig and Erhualian are all tradition Taihu pigs system kinds, tool
Having the reproductive performance of excellence, but these kinds are due to long-term locking selection-breeding, close breeding is serious, and stillborn fetus is many.For understanding
Certainly this technical problem is also removed a hidden danger, and the invention provides above-mentioned selection, it is thus achieved that novel Taihu pigs overcome the suburbs to close
Lock, maximizes and embodies hybrid vigor.In order to improve the effect of selection-breeding of the present invention, on Juvenile stage, described rice pig,
Prunus mume (sieb.) sieb.et zucc. mountain pig, Fengjing pig, Erhualian parental generation litter size are being not less than 14, physical health.
The present invention expands its hybrid vigor by reciprocal crosses, finally obtains the Taihu pigs kind of four strains hybridization, wherein,
The healthy anosis offspring of selection-breeding and hair color are consistent, and every tire number born alive is not less than 14, and every provides young number of living sow year
It is not less than the offspring of 30, through 6～8 breedings from generation to generation.
Beneficial effect: prunus mume (sieb.) sieb.et zucc. rice two maple Taihu pigs and the prunus mume (sieb.) sieb.et zucc. mountain pig that the present invention obtains etc., without compared with the Taihu pigs of hybridization, always produce
Young number, number born alive are significantly improved, and protect the heritability of China's Native Pig reproductive performance, and produce numerous for pig
Grow the high-quality female parent breed system that industry provides special.
Accompanying drawing explanation
Fig. 1 is prunus mume (sieb.) sieb.et zucc. rice two maple Taihu pigs breed breeding flow chart of the present invention.
Detailed description of the invention
Embodiment
As it is shown in figure 1, a kind of Taihu pigs selection of the present invention includes:
One, Juvenile stage and cultivation
Select Taihu Lake basin Erhualian, prunus mume (sieb.) sieb.et zucc. mountain pig, Fengjing pig, rice pig as parent.Require to select individual kind purer,
Appearance meets each varietal characteristic, and parental generation average litter size is more than 14, physical health.
Two, outbreeding
By rice pig and Mei Shan pig reciprocal crosses, breed rice after the rainy season paternal and maternal；By Fengjing pig and Erhualian reciprocal crosses, numerous
Grow two maples paternal and maternal；By Mei meter and the reciprocal crosses paternal, maternal of two maples, producing meter Er Feng tetra-after the rainy season is offspring.
Three, expanding propagation is promoted
Setting up prunus mume (sieb.) sieb.et zucc. rice two maple and cultivate system, start selection-breeding from zero from generation to generation, the healthy anosis offspring of selection-breeding and hair color are consistent, every tire
Number born alive is not less than 14, and every provides the offspring that young number of living is not less than 30 sow year, through 6～8 selection-breeding from generation to generation,
After macroscopic features and Farrowing Traits are fixed, carry out group expanding popularization, it is thus achieved that the prunus mume (sieb.) sieb.et zucc. rice two maple Taihu pigs of genetic stability.
Test example 1 prunus mume (sieb.) sieb.et zucc. rice two maple and the contrast of prunus mume (sieb.) sieb.et zucc. mountain swine reproduction performance
The prunus mume (sieb.) sieb.et zucc. rice two maple Taihu pigs (maternal) utilizing the breeding method of the embodiment of the present invention to obtain is chosen in this test, the most right
The data obtained compare with prunus mume (sieb.) sieb.et zucc. mountain pig, carry out data statistic analysis with statistical software.Result is as shown in table 1, table 2.
Table 1 prunus mume (sieb.) sieb.et zucc. rice two maple is compared with prunus mume (sieb.) sieb.et zucc. mountain pig first farrowing sow Farrowing Traits
Note: colleague compares P ＜ 0.05 and represents that significant difference, P ＜ 0.01 represent that difference is extremely notable, and P ＞ 0.05 represents that difference is the most notable.Lower same.
Table 2 prunus mume (sieb.) sieb.et zucc. rice two maple is compared with prunus mume (sieb.) sieb.et zucc. mountain pig Suprapubic arch sling Farrowing Traits
The above results shows, the prunus mume (sieb.) sieb.et zucc. rice two maple new varieties Taihu pigs that the present invention provides, and always farrows with prunus mume (sieb.) sieb.et zucc. mountain pig first farrowing sow
Number, the equal significant difference of number born alive.The total yield coefficient of Suprapubic arch sling, number born alive, year number pigs born significant difference, pregnant
Spacing difference of being pregnent is the most notable.
The above is only the preferred embodiment of the present invention, it should be pointed out that: for those skilled in the art
For, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications are also
Should be regarded as protection scope of the present invention.
