Abstract
The broiler breeding process features the selection of parents to be hybridized with the intramuscular fat content of breast chicken or leg chicken as main characteristic while considering also the growth speed and egg laying amount. In the same time, the individuals are supplementarily molecule mark selected early based on the genotype of inosinic acid molecular mark of fatty acid-binding protein. The method of the present invention can breed excellent broiler variety with powerful marketing competitive power and makes it possible for famous local Chinese chicken variety to enter international market.
Description
[technical field]
The present invention relates to the fowl breeding method, particularly improve the breeding method of fryer quality.
[background technology]
Meat matter improve one of dominant direction that becomes current fryer breeding.In the past in the time of two more than ten years, the fryer breeding is always based on commodity property seed selections such as productivitys such as growth rate, reproductive performance and plumage look, the colours of skin.In actual breeding, consider that meat mainly is conceived in the selection of breeding material, how with local chicken kind how much the judging of shared blood relationship in supporting system, and do not list high-quality index in selection plan.As the Chinese patent application notification number is the Chicken breeding supporting technology of putting down in writing in the CN1135282 patent application publication, the result of this selection causes growth rate of chicken and reproductive performance to improve constantly easily, but meat matter but adverse consequences that meat matter may descend.Therefore, a difficult problem of high quality meat chicken breeding is exactly the inconsistency of breeding objective and seed selection proterties.In addition, in breeding, carry out molecular marker assisted selection in early days, can shorten the epoch at interval, reduce the later stage number of animals raised, save feeding cost and cultured space, this technology is the theme of current breeding technique development.And the key that addresses this problem is sensitive indicator and a suitable breeding method of selecting to react the meat proterties.
Yellow-feather broiler with China is an example, domestic yellow-feather broiler kind and the supporting system that has emerged a multitude of names, wherein most supporting strains are without long-term systematic breeding, some is the single-cross of landrace and adventive, fast large-scale coloured plumage fryer of have even utilization and laying hen hybridization back are with the direct listing of yellow-feather broiler name, cause on the market a lot of fryer appearance to exactly like ground necromancer chicken, but the chicken quality can't ensure.This has not only upset the normal development that yellow-feather broiler is produced, and unfavorable to the preservation of the landrace resource of the many preciousnesses of China.A major reason that causes this trouble waters is to lack the yellow feather dwarf broiler kind (being) that the meat proterties is outstanding, can use in scale, intensification are produced.Between two decades of " six or five " to " 95 ", the breeding work of yellow-feather broiler exists breeding objective (high-quality) and the inconsistent problem of seed selection proterties all the time, be that seed selection work is leading indicator with productivity (growth rate, reproductive performance) and appearance features (plumage look, the colour of skin and build etc.) always, in breeding objective, never consider the proterties and the index of relevant meat, only with the quality that how much embodies meat of local chicken kind blood relationship.And productivity and apparent proterties and meat matter do not have direct relation, and the local chicken kind also not necessarily is high grade chook entirely.The result of this selection causes growth rate, reproductive performance and the regularity of chicken to improve constantly easily, but the adverse consequences that meat matter constantly descends.
Intramuscular fat content just is the key factor that influences animal meat local flavor in the animal muscle.Herding research institute of the Chinese Academy of Agricultural Sciences begins from national the Tenth Five-Year Plan (2001-2005), is the seed selection that major traits carries out high quality meat chicken with the intramuscular fat, and the research has been listed in country " 15 " Program for Tackling Key Problems.Primary Study result shows, at the P of fatty acid-binding protein gene A-FABP gene
4On the site, three kinds of genotype are arranged, be AA type, AB type and BB type, brisket intramuscular fat content significant difference between the different genotype, wherein the BB type is the highest in 90 age in days Beijing fine breed of chicken with thick brownish feathers colonies, the AB type takes second place, AA type minimum (with the dry matter is that basic calculation is respectively 3.028%, 2.722% and 2.489%, calculates with the fresh meat sample and then is respectively 2.24%, 2.014% and 1.892%).Judge that in view of the above the A-FABP gene is relevant with the chicken intramuscular fat content, therefore, the gene that this gene can be served as a mark carries out molecular marker assisted selection to intramuscular fat content.
[summary of the invention]
[technical problem that will solve]
The object of the present invention is to provide and a kind ofly can improve fryer meat matter local flavor, can keep the breeding method of productivity and appearance character again.
[technical scheme]
The technical scheme that solves this technical problem is: with intramuscular fat content in Fresh Grade Breast or the chicken leg meat is major traits, takes into account growth rate and egg production, and hybrid strain is selected.
Wherein, can adopt the core group selection-breeding method to carry out pure line selection to the parent, utilize family full sibs or half sibs back-and-forth method to carry out characteristic index and select, adopt composite index law that each family is carried out Comprehensive Assessment, the composite index of selecting and remain value is higher than the family of mean value and reserves seed for planting.At breeding group offspring 7～10 ages in days, can determine selecting and remain of hybrid strain individuality simultaneously, carry out the early molecule marker assisted selection according to the fatty acid-binding protein gene marker genotypes of individuality.Utilizing two to be supporting or three series mating or four is one of supporting when carrying out Chicken breeding, in the average Fresh Grade Breast of at least one system the intramuscular fat weight content be not less than 0.3% or chicken leg meat in the intramuscular fat weight content be not less than 1.0%.
[beneficial effect]
Beneficial effect of the present invention is: first, the comparable previous level of the 90 age in days chicken intramuscular fat contents that the present invention cultivates improves more than 10%, the fryer of high intramuscular fat content has the powerful market competitiveness, and this enters the international market to the famous and precious chicken kind of place of china comprehensively will play very important effect.Second, the present invention serves as international initiative with the key gene that influences intramuscular fat content as the technology that candidate gene carries out the early molecule marker assisted selection, carry out molecular mark with the high intramuscular fat content molecular labeling that filters out, the 1st seed selection time can be advanceed to 10 ages in days at least from 56 ages in days, save breeding spending about 20% thus.Promote father and mother for kind of chicken 200,000 covers by annual, can produce 2,000 ten thousand commodity chick every year.If raise father and mother for 50 yuan of the every cover profits of kind of chicken, 1.5 yuan of every profits of raising commercial chicken, then annual total economic benefit can reach 4,000 ten thousand yuan.
