Yangzhou Goose is regarded as the first new goose species in China. This is a project that the Jiangsu Provincial Science and Technology Commission has issued in both the “Eighth Five-Year Plan†and “Ninth Five-Year Planâ€. Yangzhou Goose has the following characteristics: First, Yangzhou Goose concentrates the advantages of the male parent and the female parent. It has fast growth, good meat quality, and high reproductive rate. Generally, 70-day-old goslings can reach 3.3 to 3.5 kg. , than the growth rate of the Taihu Goose is 27.8%. The second point is that the offspring meat is good, and the protein content of meat is 1% higher than that of its father. Third, the egg production level is relatively high. The annual egg production can reach 72 to 75 pieces, and 62 to 64 goslings can be produced. It is also resistant to rough feeding and can be eaten in any grass when grazing. First, the origin of Yangzhou geese China's geese species rich and diverse resources, adaptability and production performance vary. In the northeast, there are seed geese known for their egg production and Huge gooses. In the northwestern border, Xinjiang has Ili geese adapted to the cold climate of the plateau, in the south of Guangdong Zhanjiang, there are lion-headed geese with large meat fat, and in the southwest, Chengdu and Chongqing have fast growing and producing. Sichuan white geese with many eggs, Huazhong Hunan have good Lupu geese with good liver properties, Jiangsu has good mutton flesh and many eggs, Taihu geese in Zhejiang, Zhejiang, Anqing with Zhedong white goose with egg production all year round and Anhui with crude feeding Wild geese and white geese in the west, the masses call it the “season goose†and so on. These local breeds not only have a wide range of natural ecological adaptability, but also have strong resistance to stress, and they also contain greater genetic variation and selection potential. However, due to the fact that our country’s geese farming industry has long existed in the form of rural sideline industries, grazing is the mainstay, and its husbandry and management are extensive and the production level is low. Many varieties have not yet been scientifically and systematically selected. Big differences and lack of consistency. In addition, due to the long-term decentralization of peasant households, most geese species in China’s geese breeds have strong nesting and few eggs. For example, lion-headed geese and Anhui wild geese have strong nesting capacity, and only 25-35 eggs are produced annually. Pieces. The geese raising industry is a traditional characteristic industry in our city. It has abundant natural resources, a solid technical foundation, long-term accumulated practical experience, a market with strong demand, and a lack of ideal and fine varieties. In order to increase the efficiency of raising geese, increase the income of farmers, meet the market demand, and promote the development of animal husbandry and even the entire rural economy, in 1990 the city introduced the Sichuan Longchang Goose (ie Sichuan White Goose) to conduct research on development and utilization. Under the auspices of Prof. Zhao Wanli of the College of Animal Husbandry and Veterinary Medicine, the Yangda Animal Husbandry and Veterinary College and the former Municipal Bureau of Multi-Administration (now the Agricultural Bureau) began to use the Longchang Goose with fast growth, many eggs, and no nesting, with good meat quality and more eggs. No nesting Taihu Goose and Wanxi White Goose were tested for hybridization and combining ability. A better combination was selected for backcrossing and backcrossing. A best combination was then screened for generation selection. So far it has entered. The sixth generation. At the same time, the relevant basic research, the exploration of new breeding theories and methods, the research on the early growth and development of Yangzhou goose, the research on the nutritional requirements and digestive mechanisms of goose, etc., were carried out around the breeding of Yangzhou geese. Studies on the relationship between the change of hormone content and the growth performance of goose geese in plasma, and the correlation between karyotype and banding analysis of Yangzhou geese and production performance, and the study on the comprehensive prevention and control technology of goose diseases etc. Eleven aspects of research trials. The breeding of Yangzhou geese was listed as the "Eighth Five-Year Plan" and "Ninth Five-Year Plan" research projects by the Provincial Science and Technology Commission. After more than ten years of painstaking research and hard work, a new breed of local fine geese was bred. In August 2002, the province passed poultry. The Variety Committee approved and officially named Yangzhou Goose. Second, characteristics and development status of Yangzhou geese 1. Features of Yangzhou geese. Yangzhou Goose is the first new species developed in China using domestic goose breeding resources. It is an ideal medium-sized goose species. As determined by the National Poultry Production Performance Measurement Station, Yangzhou Goose has a moderate body size, good uniformity, and stable genetic properties; meat geese have early growth, resistance to rough feeding, strong adaptability, delicious meat, high muscle protein content, and fine muscle fibers. Room fat is rich, water content is low, processing rate is high, palatability is good; the geese under the grazing supplemental conditions, the average live weight of 70 days is 3.49 kilograms, the average live weight of 70 days is 4.02 kilograms; The breeding performance of the geese is good. The average egg production of the breeding goose is 71.39 pieces, and the fertilization rate and hatching rate of the breeding eggs are all above 90%. The conclusion of the test is that “the growth rate of Yangzhou goose goose has reached the advanced level at home and abroad, and the breeding goose has reached the advanced level in the worldâ€. 2, the development status quo. Yangzhou Goose has two breeding bases: Yangzhou Goose Breeding Center of Jiangsu Province and Yangzhou Goose Breeding Goose Field of Gaoyou City. There are 50,000 basic breeding groups, 0.5 million core groups, and 40 family members. At the same time, some expansion fields have been established. There are 200,000 breeding geese. In addition, other fine varieties are being introduced, paternity is being bred, and experimental studies of specialized strains and mating lines have been established. The effect of Yangzhou goose trials in the breeding process is also very significant. So far, apart from being promoted in this city, it has been promoted in more than ten provinces and cities such as Anhui, Yancheng, Hongze, Wujin, Zhenjiang, Zhangjiagang, Dongtai, Xinghua and Shandong, Henan, Shanghai, Heilongjiang and Anhui. Try to raise and succeed. Gaoqiao Shijiao Town is one of the Yangzhou geese breeding bases. In recent years, the town party committee and the town government have promoted Yangzhou geese to a large degree and proposed the geese industry to develop the town and raise Yangzhou geese to more than 500,000. Last year, through investment promotion, the company invested 5 million yuan to set up Tiange goose meat processing plant. The plant and the farmers directly signed the Yangzhou Goose Breeding Agreement and implemented protection price acquisition. Gongyi City, Henan Province, introduced Yangzhou goose breeding. After several years of experiment and promotion, they believed that Yangzhou geese can adapt to the natural ecological environment and relatively extensive feeding and management conditions in the vast areas of Huanghuai River Valley. The early growth rate of young geese and high breeding geese eggs are high. In Sichuan white goose. In Huishan, Shandong Province, the average egg production period was 77.6 eggs. The natural mating rate and fertilization rate reached 87.6-91.2%, and the hatching rate was about 85%. They believe that Yangzhou Goose is indeed a fine goose species, with resistance to rough feeding, strong foraging, wide range of adaptation, strong disease resistance, suitable for grazing or captivity, the early growth and development of broiler goslings. The breeding of geese has many advantages such as high egg production, large eggs and good reproductive performance. Due to the high quality and high yield of Yangzhou geese germplasm and obvious economic benefits, there are ten news media such as Xinhua Daily, China Animal Husbandry and Fisheries News, Science and Technology Daily, Yangzi Evening News, China National Poultry, and Central People's Broadcasting Station. And professional magazines have special reports on them and have a great response in society. At present, there are already 24 provinces (cities) in the country that have demanded the introduction of breeding, the purchase of letters and culverts, and the constant telephone calls. There is plenty of room for market demand. Third, accelerating the development of Yangzhou Goose 1. Continue breeding to improve the production performance of Yangzhou Goose. (1) Expand family. The number of families has expanded from the current 40 to 160, and 1200 breeding geese have been raised. (2) Introduce 2-3 provenances, establish paternal lines, establish 2-3 specialized strains, select the best combination through the determination of hybrid combining ability, and establish and establish the hybridization accessory line. (3) Do a good job of documenting family records, analyze and collate data, and strive to pass the National Poultry Breeders Committee's approval of Yangzhou Goose as soon as possible. 2. Run the Yangzhou Geese Breeding Center of Jiangsu Province. Based on the Goose Breeding Goose Farm in Yangzhou, and taking full advantage of the natural resources, species, and market technology in Yangzhou, we will gradually establish and improve the breeding system for Yangzhou geese, and undertake the breeding, breeding, seed production, propagation, promotion and demonstration of Yangzhou geese. The center has to invest about 3 million yuan to complete the main infrastructure for breeding goose farms, including 4 family geese, 4 experimental geese, 1 brooding room, 4 kinds of goslings, quail hatchery, and in-site water and electric circuits. Supporting facilities, etc., the breeding family of 300 goose breeding geese, 0.5 million core species of geese. Through several years of efforts, the goose farm was built into the Yangzhou Goose demonstration park. 3. Accelerate the promotion of Yangzhou Goose. In each county (city) of the city, 1 to 2 Yangzhou goose breeding sites are set up. At the same time, more than 10 breeding farms are established inside and outside the province, and each breeding farm is fed with 0.5 to 10,000 parental generations. In addition, a number of breeding farms and specialized breeders for breeding geese have been set up, striving to make Yangzhou geese account for more than 80% of merchandise geese through the "tenth five-year plan" and even a little more time. 4. Actively promote the supporting technology of Yangzhou goose breeding. In particular, it is a disease prevention and control technology for raising grasses and raising geese, autumn incubating and winter raising, intensive feeding, and geese. It is necessary to strengthen training and do a good job of typical demonstrations so that more farming units and individuals can skillfully master the knowledge and production skills of geese, mobilize enthusiasm, and increase the benefits of geese. 5. Vigorously promote the industrialization and pollution-free breeding of Yangzhou Goose. Focus on cultivating leading processing enterprises and goose specialty wholesale markets, develop various rural geese cooperative economic organizations or associations, train farmers brokers, integrate farming and processing, production and market organically, and actively create conditions to form a joint fleet ——Yangzhou Goose Industry Group further enhanced the organization and socialization of Yangzhou goose industry. At the same time, the establishment of more than 500,000 pollution-free breeding bases for Yangzhou geese in 10 years. One base is a Yangzhou Goose Park. The park integrates breeding geese breeding, cocoon hatching, commercial goose breeding, feed production (including green feed), and commercial goose processing and sales. It is necessary to strengthen monitoring of the base environment including soil, water sources, and atmosphere, and conduct full monitoring of the input products, including seedlings, feed, and medicines used for disease prevention and treatment, and conduct breeding in accordance with the “Yangzhou Goose Feeding Technical Specifications†to further improve the Yangzhou goose. Product quality and safety, increase market competitiveness, expand market coverage, and promote the development of Yangzhou geese.
