Abstract
The present invention discloses boar hybridizing method, comprises the following steps：1) it is maternal by the use of pure Duroc as first using purebred Duroc as the first male parent；2) using generation Duroc as the second male parent, the first maternal backcrossing with pure Duroc；3) using two generation Durocs as the 3rd male parent, the first maternal backcrossing with pure Duroc；4) using three generations's Duroc as the 4th male parent, the first maternal backcrossing with pure Duroc；5) using four generation Durocs as the 5th male parent, the first maternal backcrossing with pure Duroc；6) using five generation Durocs as the 6th male parent, the first maternal backcrossing with pure Duroc.Beneficial effect：Caused duroc kind can do cultivation and sell during backcrossing, will not cause the wasting of resources, the cost of the effectively save boar hybridization of energy, and can obtain purer duroc kind.
Description
Technical field
The invention belongs to technical field of livestock husbandry, and in particular to boar hybridizing method.
Background technology
Western countries' pig industrys such as the initial stage eighties in last century to the nineties, American and Britain mainly with Large White, Landrace and
Duroc carries out the production of " foreign ternary " pork pig as boar, from after breed system appearance, a few years Swine Production 80%
The market share just occupied by this new production model.Compared with existing pig kind, breed system pig has larger kind
Advantage, traditional quality pigs kind can only often embody such as fast one, two advantage of lean meat percentage height, the speed of growth, and breed system then may be used
To embody a concentrated reflection of multiple advantages.The French Academy Jean NAVEAV are made female using China's Taihu pigs (plum mountain pig and Jiaxing Black Pig)
This, by the work of 8 years, cultivate " wet nurse " it is new maternal, and with P76 paternal line corss combinations；Also PIC companies, also using too
The performance that lake pig reproductive capacity is high, meat is good is cultivated new maternal " Kang Beier ", and is hybridized with 402 paternal lines, is formed 5 fixed systems and is matched somebody with somebody
Cover to produce miscellaneous excellent pig, so as to solve to some extent, reproductive capacity is low, the contradiction of meat difference.
The content of the invention
In view of the above-mentioned problems of the prior art, duroc kind is pure after hybridization is effectively ensured in present invention offer one kind
Boar hybridizing method.
Its technical scheme is：
Boar hybridizing method, comprises the following steps：
1), by the use of pure Duroc as the first female parent, hybridize generation Du as the first male parent using purebred Duroc
Luo Ke, the growth cycle that generation Duroc grows to finished product pig from cub is 6-8 months；
2) two generations Du the first maternal backcrossing with pure Duroc, is returned out as the second male parent using generation Duroc
Luo Ke, the growth cycle that two generation Durocs grow to finished product pig from cub is 6-8 months；
3) the first maternal backcrossing with pure Duroc, it is returned out three generations Du as the 3rd male parent using two generation Durocs
Luo Ke, the growth cycle that three generations's Duroc grows to finished product pig from cub is 6-8 months；
4) four generations Du the first maternal backcrossing with pure Duroc, is returned out as the 4th male parent using three generations's Duroc
Luo Ke, the growth cycle that four generation Durocs grow to finished product pig from cub is 6-8 months；
5) the first maternal backcrossing with pure Duroc, it is returned out five generations Du as the 5th male parent using four generation Durocs
Luo Ke, the growth cycle that five generation Durocs grow to finished product pig from cub is 6-8 months；
6) the first maternal backcrossing with pure Duroc, it is returned out six generations Du as the 6th male parent using five generation Durocs
Luo Ke, the growth cycle that six generation Durocs grow to finished product pig from cub is 6-8 months；Obtain pure duroc kind.
Preferably, the first female parent of the pure Duroc is same female parent.
Preferably, the first of the first male parent of described purebred Duroc and pure Duroc it is maternal for it is physical strong,
The duroc that strong stress resistance, the speed of growth are fast, carcass lean meat percentage is high.
Preferably, the pure rate of blood lineage of the 6th generation duroc is more than 99.9%.
Preferably, terramycin is taken after the first of the pure Duroc the maternal farrowing, red, yellow dysentery occurs to prevent piglet.
Beneficial effect：
Boar hybridizing method provided by the invention, it can further obtain pure Duroc by way of being simply returned
Pig kind, the cost of boar hybridization is saved, and it is simple to operate, extra urgent loss will not be caused in operating process, backcrossing
During caused duroc kind can do cultivation and sell, the wasting of resources will not be caused, can effectively save boar hybridization
Cost, and purer duroc kind can be obtained.
