  Concise and accurate description of the research background of the results, the main technical solutions and contents, the main scientific and technological innovation points, the status of authorized patents and intellectual property rights, the comparison of the overall technical and economic indicators achieved with similar advanced technologies at home and abroad, the maturity of the technology and the promotion of application and benefits, etc. Science popularization achievements should objectively, accurately and briefly introduce the audience, innovative methods, forms of expression, contents of dissemination of scientific and technological knowledge, distribution, etc. (1600within the word).

(I)Science and technology field: animal husbandry poultry science

(II)Main contents and characteristics

Quail is a special economic poultry. Quail eggs have high nutritional value and are called "animal ginseng" with strong market demand. Chinese Quail Breeding from 1978After 50 years of rapid development,Now the scale of breeding ranks first in the world, and the breeding varieties include the introduction of Japanese quail, Korean quail, Nannong Huang Yu system, white feather system, etc. Hubei is the main producing area of quail breeding, and the processing of quail eggs ranks in the forefront of the country. Quails begin to lay eggs at the age of 35 days, with short feeding cycle, low investment and quick results, which has become one of the important starting points for increasing farmers' income, targeted poverty alleviation and agricultural supply-side structural reform.

Quail breeding and egg processing in Hubei Province ranks first in the country. The project aims at the problems of few quail varieties, uneven egg shape and difficult processing, imperfect breeding technology, which can not meet the needs of large-scale breeding. With the support of the scientific and technological achievements transformation project of Hubei Provincial Science and technology department, the animal husbandry and Veterinary Research Institute of Hubei Academy of Agricultural Sciences and Hubei Shendan Health Food Co., Ltd. have carried out the genetic analysis of important economic traits of quail and the cultivation of supporting departments. After 13 years of research, 41Item, of which: New variety 14 specialized strains, 13 patents, 2 local standards, 1 book, 3 egg processing products and 17 papers. The main innovations are as follows:

1The original innovation, the use of genome-wide association analysis revealed the genetic basis of quail feather color and other characteristics, screening out 23.A new SNP associated with quail feather color, weight, and egg-laying traits.Molecular markers.

The whole quail genome was sequenced and re-sequenced de novo using core germplasm resources, and the quail genome was assembled to obtain a total of 1332Gb.Data, accounting for 84.6 per cent of the world's similar; The assembled quail genome is about 1.04Gb in size, and 16210 functional genes have been annotated, including 238 new genes. The molecular genetic basis of quail breed characteristics and characteristics such as feather color, body weight and precocious puberty was revealed for the first time by genome-wide association analysis. Five new quail genes such as precocious puberty were identified, and 23 new molecular markers for traits such as feather color, body weight and egg production were developed, it has significantly improved the basic research level of quail in China. Apply for 3 national invention patents, published 4 SCI papers, with independent intellectual property rights.

2The first national quail new breed (Supporting Department)

Collection of genetic resources at home and abroad, the use of full-sib family breeding and molecular marker-assisted breeding combined methods, selected 4A specialized strain, bred to be suitable for processing Shen Dan 1Quail supporting line, which is the first new livestock and poultry variety (supporting line) approved by the state in Hubei Province since the establishment of the National Livestock and Poultry Genetic Resources (Management) Committee, is also the first new quail variety (supporting line) approved by the state in China, filling the gap in China. Compared with foreign quail, it has three characteristics: save feed by 10%; Egg production rate increased by 10%; Egg shape is uniform, and processing damage is less. The special breeding equipment for quail was developed, which improved the accuracy of genetic determination. Using quail feather color molecular markers to identify pure genotype individuals, the breeding cycle was shortened by 2 years, and the accuracy rate of self-differentiation of feather color of commercial quail was 99%. Two local standards were formulated, 10 papers were published and 1 monograph was published.

According to the characteristics of quail, such as small size, fast growth and early laying, the project team has designed efficient quail breeding technology, a complete set of breeding observation equipment and artificial auxiliary natural mating technology, which provides guarantee for family reproduction and accurate collection of breeding data of each individual in quail breeding. The accurate acquisition of quail family breeding and individual production performance data has ensured the smooth implementation of family breeding.

3The technology system of standardized quail breeding and processing has been constructed.

In view of the lack of special cages and low degree of automation in the process of large-scale breeding of egg quails, a series of breeding equipment and facilities such as fully automatic breeding quail cages and automatic feeding devices have been studied and designed. According to the physiological characteristics and nutritional requirements of caged quails, a special feed formula for quails has been developed, which provides a guarantee for the full play of quail production performance; formulated local standards covering farm planning, breeding, breeding management, etc., and compiled and published a monograph on quail breeding 1.Department, put forward the quail standard breeding technology program, promote the quail industry to large-scale, automatic breeding mode transformation; according to the characteristics of quail eggs, developed baked eggs, bast marinated eggs, containing quail egg hydrolysate hand cream, etc. 3This new product has extended the quail breeding industry chain, greatly increased the added value of the product, and promoted the upgrading of the quail industry's large-scale and intensive breeding technology. Authorized 14 national patents, including 6 invention patents, 8 utility model patents; 3 new products.

(III)Application and promotion

Project Creation "Combination of Hospital and Enterprise"The promotion and application mode of "integration of breeding, propagation and promotion" has been applied to more than ten provinces and cities such as Hubei, Shaanxi and Zhejiang. 2017-2018 onlyA total of 2.15 million sets of quail parents and 24.269 million sets of quail products were promoted in Shendan No. 1, with a new output value of 0.552 billion yuan and a new profit of 0.11 billion yuan. Hubei has a market share of more than 70%, with significant economic and social benefits. The application prospect is broad.
