Description
Technical field
The present invention relates to poultry breeding technical fields, and in particular to a kind of cultivation side of " black ternary " breed system meat pig
Method.
Background technique
Current 80% or more pork is produced by the fast long white pig of lean meat species based on " Ternary Pig " foreign ternary, shared by black pig
The market share is low, but with the development of economy, and demand of the consumer to high-quality high-grade pork gradually increases, and white the produced meat of pig is
It is not able to satisfy the demand in market.Therefore carry out hybridization extensively in pig variety Breeding Process both at home and abroad.Due to " Ternary Pig " be generation
The white pig market occupancy volume of table is big, and the research of white pig crossing pattern is more, in the black current hybrid process of pig also extensively using white pig or
Person only hybridizes between two kinds, the black pig breed system in Sichuan-Tibet of authorization in 2013, also not mating all of black pig,
The duroc of brown is utilized in part.Specialized strain is established using three black pig varieties, it is excellent to carry out breed system hybridization production
The not disclosed report of the black pig of matter characteristic.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of breeding method of " black ternary " breed system meat pig, trainings
Educate that the speed of growth is fast, the black pig of the good characteristic of meat, to meet the market demand.
In order to achieve the above object, the present invention is achieved by the following technical programs:
A kind of breeding method of " black ternary " breed system meat pig, comprising the following steps:
(1) breeding group is set up: divided the work according to each system's performance and status in mating breeding of method, to selected boar into
The stringent identification of row, selection select outstanding people pig as paternal maternal, Berkshire boar as paternal male parent, Songliao Black Pig Heart Fatty
As maternal female parent, breeding group is set up；
(2) crossbreeding: Berkshire is hybridized with people pig, and the offspring of generation passes through breeding, and it is miscellaneous to cultivate Ba Min
Black pig is handed over, then using Ba Min hybridization black pigs as male parent, Songliao Black Pig Heart Fatty is that the maternal maternal natural breeding, that is, traversed by that carries out is fixed, and is used
Multiple characters animal model BLUP method carries out genetic evaluation to boar, mainly chooses seeds by multiple selection index, controls standby
Boar selects and remain ratio, cultivates " black ternary " breed system meat pig.
Preferably, paternal male parent includes 6 or more not syngenesious boars in step (1) breeding group.
Preferably, the generation inteval is 1.5 years generations in the step (2).
Preferably, standby boar selects and remain ratio in the step (2) are as follows: boar control is controlled in 5-10:1, sow in 2-
3:1.
The invention has the advantages that: the present invention to use " black ternary " crossing pattern, using people pig as paternal maternal, Berkshire public affairs
Pig is as paternal male parent, and Songliao Black Pig Heart Fatty is as maternal female parent, by being latched the technology combined with not exclusively locking Systematic Breeding
Route, " black ternary " breed system meat pig heritability cultivated are stablized, fast, the good characteristic of meat with growth and development
Black pig provides high-quality black pork for the majority of consumers, meets the market demand.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention,
Technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is the present invention one
Divide embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making
Every other embodiment obtained, shall fall within the protection scope of the present invention under the premise of creative work.
Embodiment:
Using " black ternary " mode, three series mating hybridization sets people pig (A system) same to Berkshire (B system) hybridized pig as father
This paternal line (AB), Songliao Black Pig Heart Fatty are maternal maternal (C), i.e. AB × C three series mating hybridizes.
(1) it chooses seeds: according to the division of labor of each system's performance and the status in mating breeding of method, selected boar being carried out stringent
Identification, selection.1. according to the rule of the specialized paternal maternal division of labor, in conjunction with Trait heritability, genetic correlation, hybrid vigour
And the combined factors such as selection intensity consider, breed system major traits are determined as grow-finish character 2: the speed of growth and back fat
It is thick；Reproductive trait 1: litter size；Meat Quality 1: intramuscular fat.The specific division of labor is as follows, and A owner selects reproductive performance and back
Fat thickness takes into account the speed of growth, forms prolificacy system；B owner selects the speed of growth and intramuscular fat, forms fast-growth system, C system
Main to select intramuscular fat, litter size, adaptability, breeding is at high-quality fecund.2. the specific combining ability between breeding raising parent system,
Hybrid performance is included in breeding system, general close to making when being bred as in new lines to make full use of non-additive gene effect
Coordinate force test makes idle gender boar be fully used.3. eliminating some character for the regularity for keeping hybridization market pig
Prominent and individual that other characters are especially low；Parent system adheres to that appearance traits evaluation includes wean, six-month-old and adult rank
Section, it is desirable that constitution is solid, three-dimensional-structure is well-balanced, coordinates, using ideal premium muscle type market pig figure as standard, using body ruler
Character combined method is identified.
(2) breeding group is set up: selection people pig and Berkshire boar blood relationship 6, and sow 50, male parent paternal line Ba Min hybridization is black
Pig scale is 20 male 100 mothers, and 10 blood lineages of boar, 40 blood lineages of sow, appearance traits are consistent；Maternal maternal Songliao Black Pig Heart Fatty core
It is female that heart group's scale reaches 30 male 300.
(3) Breeding measures:
1. technology path: using modern genetics, thremmatology as theoretical direction, using breed system latest theories as guide, using
It is latched the technology path combined with not exclusively locking Systematic Breeding, a generation of 1.5 years generation intevals, standby boar selects and remain ratio
Example are as follows: boar control is controlled in 5-10:1, sow in 2-3:1.Boar is lost using multiple characters animal model BLUP method
Assessment is passed, is mainly chosen seeds by multiple selection index.
2. performance measurement；Including each system's Reproductive Performance, the performance measurement of standby boar and fattening are butchered, meat quality determination
And appearance traits identification.
3. combining ability test: being used to check specific combining ability between each system, confirm Breeding Progress, and make ginseng when each systematic selection
It examines, further includes the general combining ability measurement of the idle gender pig kind of each system and other outer kinds (strain) of breed system.
4. the computerized processing of breeding information: selection supervises breeding overall process using kind of a pig farm information management software
Control, prediction and the simulated experiment of breeding system and optimization design etc..
5. breeding new and high technology is explored and application: for the biochemical genetic marker of prediction of heterosis, marker assisted selection
Application strategy and use systematic approach are used for breeding system and breeding of method optimizing research etc..
