Abstract
The invention discloses a selection method of Taihu pigs and belongs to the field of animal breeding. Reciprocal cross is performed on measly pigs, Meishan pigs, Fengjing pigs and Erhualian pigs from the TaiHu lake area, thus heterosis is expanded, a breeding line of Meishan pig-measly pig-Erhualian pig-Fengjing pig is established, and a breed which is high in reproductive performance and stable in heritability is selected. Compared with the Taihu pigs without hybrid cross such as Meishan pigs, the Taihu pigs subjected to the reciprocal cross are high in total number born and number born alive, the defect brought by selfing of the Taihu pigs is overcome, the heritability of the reproductive performance of local pigs in China is maintained, and a special high-quality female parent specialized line is provided for pig production and breeding 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 Introduced From Abroad grows soon, the price of deed is high pig kind and China native breed hybridizes; Or carry out this breed breeding of land race.Taihu pigs is the pig kind that litter size is maximum in the world, and often as the female parent of hybridization, principal item comprises plum mountain pig, Fengjing pig, Erhualian etc.Long-term and external introduced variety is hybridized, and the resistance of cultivation kind, adaptability can be made to decline, and piglet is liable to illness; And utilizing this breed breeding, the improved variety cycle is long, and in Breeding Process, recessive gene easily overlaps, and it is healthy that kind is cultivated in impact.
From the angle of long term growth, now breeding is carried out to the pig kind of the local high reproductive performance of China and optimization is very important, thus for providing more favourable condition with other pig kind outbreedings.
Summary of the invention
Goal of the invention: the maternal new varieties in this locality that the object of the invention is to provide a kind of number born alive, crude feed tolerance ability more outstanding by crossbreed means.
Technical scheme: in order to realize foregoing invention object, a kind of Taihu pigs selection of the present invention comprises:
(1) by rice pig and Mei Shan pig reciprocal cross, it is paternal and maternal to breed rice after the rainy season; By Fengjing pig and Erhualian reciprocal cross, breed two maples paternal and maternal; By Mei meter and the paternal line of two maples, maternal hybridization, producing meter Er Feng tetra-is after the rainy season offspring;
(2) set up plum rice two maple and cultivate system, seed selection from zero generation, from generation to generation, group expanding is promoted, and obtains the plum rice two maple Taihu pigs of genetic stability for the offspring consistent based on hair color and fertility performance seed selection.
The parental generation of above-mentioned four strains, rice pig, Mei Shan, Fengjing pig and Erhualian are all traditional Taihu pigs system kinds, have excellent reproductive performance, but these kinds are due to long-term locking seed selection, and close breeding is serious, and stillborn foetus is many.In order to solve this technical problem and remove a hidden danger, the invention provides above-mentioned selection, the novel Taihu pigs of acquisition overcomes suburbs locking, maximizes and embodies hybrid vigour.In order to improve the effect of seed selection of the present invention, on Juvenile stage, described rice pig, plum mountain pig, Fengjing pig, Erhualian parental generation litter size are being not less than 14, physical health.
The present invention expands its hybrid vigour by reciprocal cross, finally obtains the Taihu pigs kind of four strains hybridization, wherein, the healthy anosis offspring of seed selection and hair color is consistent, every tire number born alive is not less than 14, and every provides young number of living to be not less than the offspring of 30 in sow year, through 6 ~ 8 breedings from generation to generation.
Beneficial effect: plum rice two maple Taihu pigs and plum mountain pig that the present invention obtains etc. are without compared with the Taihu pigs of hybridizing; total yield coefficient, number born alive are significantly improved; protect the heritability of China's Native Pig reproductive performance, and provide special high-quality maternal breed system for pig Reproduction industry.
Accompanying drawing explanation
Fig. 1 is plum rice two maple Taihu pigs product clock seed selection flow chart of the present invention.
Embodiment
Embodiment
As shown in Figure 1, a kind of Taihu pigs selection of the present invention comprises:
One, Juvenile stage and cultivation
Select Taihu Lake basin Erhualian, plum 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 cross, it is paternal and maternal to breed rice after the rainy season; By Fengjing pig and Erhualian reciprocal cross, breed two maples paternal and maternal; By Mei meter and the paternal line of two maples, maternal hybridization, producing meter Er Feng tetra-is after the rainy season offspring.
Three, numerous popularization is expanded
Set up plum rice two maple and cultivate system, seed selection from zero generation, the healthy anosis offspring of seed selection and hair color is consistent, every tire number born alive is not less than 14, every provides young number of living to be not less than the offspring of 30 in sow year, through 6 ~ 8 seed selections from generation to generation, after macroscopic features and Farrowing Traits are fixed, carry out group expanding popularization, obtain the plum rice two maple Taihu pigs of genetic stability.
Test example 1 plum rice two maple and plum mountain swine reproduction performance contrast
Plum rice two maple Taihu pigs (maternal) utilizing the breeding method of the embodiment of the present invention to obtain is chosen in this test, compares simultaneously, carry out data statistic analysis with statistical software to the data obtained and plum mountain pig.Result is as shown in table 1, table 2.
Table 1 plum rice two maple is compared with plum mountain pig first farrowing sow Farrowing Traits
Note: colleague compares P < 0.05 and represents significant difference, P < 0.01 represents that difference is extremely remarkable, and P > 0.05 represents that difference is not remarkable.Lower same.
Table 2 plum rice two maple is compared with plum mountain pig Suprapubic arch sling Farrowing Traits
The above results shows, plum rice two maple new varieties Taihu pigs provided by the invention, with plum mountain pig first farrowing sow total yield coefficient, 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 is not remarkable.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
