   The research background, main technical schemes and contents, main scientific and technological innovation points, authorized patents and intellectual property rights, comparison of the overall technical and economic indicators with the same advanced technologies at home and abroad, technical maturity, application and promotion, and benefits are briefly and accurately described. The results of science popularization should objectively, accurately and concisely introduce the audience, innovation methods, forms of expression, contents and distribution of science and technology knowledge (1600 Within words).

( 1) It's a good idea Science and technology: animal husbandry and Poultry Science

( 2) It's a good idea Main contents and features

Quail is a special economic poultry. Quail eggs have high nutritional value, known as "animal ginseng", the market demand is strong. Quail culture in China since 1978 After 50 years of rapid development, At present, the breeding scale ranks first in the world, and its breeding varieties include Japanese quail, Korean quail, Nannong yellow feather line and white feather line. Hubei is the main quail breeding area, quail egg processing ranks in the forefront of the country. Quail began to lay eggs at 35 days of age, with short feeding cycle, low investment and quick effect. It has become one of the important grasp points of increasing farmers' income, targeted poverty alleviation and agricultural supply side structural reform.

Quail breeding and egg processing in Hubei Province ranks first in China. The project aims at the problems such as few quail varieties, uneven egg shape, difficult processing, imperfect breeding technology, which can not meet the needs of large-scale breeding. With the support of scientific and technological achievements transformation project of Hubei Provincial Science and Technology Department, the animal husbandry and Veterinary Institute of Hubei Academy of Agricultural Sciences and Hubei Shendan Health Food Co., Ltd. have carried out genetic analysis and matching of important economic traits of quail Working set. After 41 years of research results Among them: new variety 1 There are 4 specialized strains, 13 patents, 2 local standards, 1 book, 3 egg processing products and 17 papers. The main innovation achievements are as follows:

one The genetic basis of feather color and other characteristics of quails was revealed by genome-wide association analysis New SNPs associated with feather color, body weight and laying traits of Quails Molecular markers.

The whole genome of quail was de novo sequenced and re sequenced using core germplasm resources. The quail genome was assembled and 1332gb was obtained Data, accounting for 84.6% of global peers The size of quail genome is about 1.04gb, a total of 16210 functional genes are annotated, including 238 new genes; the molecular genetic basis of feather color, body weight, precocious puberty and other characteristics of quails is revealed by genome-wide association analysis, 5 new genes such as precocious puberty are identified, and a new molecular marker 23 for feather color, weight and egg production is developed The level of basic research on quails in China was significantly improved. It has applied for 3 national invention patents and published 4 SCI papers with independent intellectual property rights.

two The first quail new variety was bred in China( Supporting system)

By collecting genetic resources at home and abroad, 4 It is suitable for the cultivation of a special strain of Dan Since the establishment of the national livestock and poultry genetic resources (Management) committee, this is the first new breed of livestock and poultry (mating line) approved by the state in Hubei Province. It is also the first new quail variety (mating line) approved by the state, which fills in the gap in China. Compared with foreign quails, it has three characteristics: saving feed by 10%; increasing egg production rate by 10%; uniform egg shape and less processing damage. The results showed that the accuracy of genetic identification of quails was 99% by using molecular markers. 2 local standards were formulated, 10 papers and 1 monograph were published.

In view of the characteristics of quail, such as small individual, fast growth and early egg production, the project team studied and designed efficient quail breeding technology, a complete set of breeding observation equipment and artificial assisted natural mating technology, which provided guarantee for family reproduction and accurate collection of breeding data of each individual in quail breeding, and realized accurate acquisition of quail sibling family breeding and individual production performance data, The whole sib family breeding work was ensured to be carried out smoothly.

three The technology system of quail standardized breeding and processing was established

In view of the lack of special cages and low automation in the process of large-scale breeding of egg quails, a series of breeding equipment and facilities such as full-automatic cage and automatic feeding device were researched and designed. According to the physiological characteristics and nutritional requirements of caged quails, a special feed formula for quails was developed, which provided guarantee for the full play of quail production performance The local standards covering farm construction planning, breed, breeding management and other contents were published According to the characteristics of quail eggs, we developed roast eggs, phloem marinated eggs and hand cream containing quail egg hydrolysate The new products have extended the quail breeding industry chain, greatly increased the added value of products, and promoted the upgrading of quail industry scale and intensive breeding technology. 14 national patents were authorized, including 6 invention patents, 8 utility model patents and 3 new products.

( 3) It's a good idea Application and promotion

Project creation "combination of hospital and enterprise"+ It has been applied to more than ten provinces and cities such as Hubei, Shaanxi and Zhejiang. 2017-2018 only 2.15 million sets of parent generation and 24.269 million commercial generation of Shendan No.1 quail were popularized annually, with a new production value of 552 million yuan and a new profit of 110 million yuan. Hubei has a market share of more than 70%, and its economic and social benefits are remarkable. The application prospect is broad.
