How long does it take for the big white goose to eat meat?

Wanxi White Goose 1. Origin and distribution The central producing area of Wanxi White Goose is located in the hilly area of western Anhui Province and Gushi area of Henan Province, mainly distributed in Huoqiu, Shouxian, Lu 'an and other counties and cities in western Anhui. 2. Appearance characteristics: Wanxi White Goose has a medium body shape, a high posture, a heroic temperament, an arched neck, a deep and wide chest and a wide and flat back. The feathers of the whole body are white, the sarcoma on the top of the head is orange, round, smooth and wrinkle-free, the beak is orange, the beak end is pale, the rainbow is gray-blue, the shin and webbed are orange, the claws are white, and about 6% of geese have pharyngeal bags under their jaws. A few individuals have spherical feather bundles at the back of the head and neck, that is, the apical hairs. Male goose sarcoma is large and prominent, with a thick and strong neck, while female goose has a thin and short neck and slightly drooping abdomen. The types of Wanxi White Goose are as follows: there are many abdominal folds in pharyngeal pouch, few abdominal folds in pharyngeal pouch, no abdominal folds in pharyngeal pouch, no abdominal folds in pharyngeal pouch and so on. 3. Productive performance Meat production: Adult male geese weigh 6.12kg and female geese weigh 5.56kg.. Slaughter test showed that the semi-clean bore of male geese was 78%, and the full clean bore was 7%. The semi-clean bore of goose is 8%, and the full clean bore is 72%. Laying eggs: The age of laying hens is generally 6 months old, and laying eggs is mostly concentrated in January and April. The breeding of Wanxi White Goose has strong seasonality and concentrated time. Generally, female geese produce two eggs a year, laying about 25 eggs a year, and about 3% ~ 4% of female geese can lay 3 ~ 5 eggs in a row. The masses call them constant-laying geese. The average egg weighs 142 grams and the shell is white. Egg shape index is 1.47. The mother goose has a strong nest. The mating ratio of male and female is 1: 4 ~ 5, and the fertilization rate of eggs is over 88%. Wool production: The down quality of Wanxi White Goose is good. A goose produces 349 grams of down, which is especially famous for its large down. Wanxi White Goose has been listed in the "National Poultry Variety Records", with delicious meat, excellent down quality, large down and high bulkiness, which is the highest in the world. Breeding management and grazing technology of Wanxi White Goose, which originated in Lu 'an area of Anhui Province, is an excellent medium-sized goose breed in China. It is an important export material and a pillar industry of rural economy in western Anhui province. Wanxi White Goose has seven characteristics: 1. Its early growth and development are rapid. Under the condition of extensive feeding in rural areas, its weight can reach more than 1.5kg at 3 days, 3.-3.5 kg at 6 days and 4.5-5.5 kg at 9 days. The average weight of adult male geese is 6.8kg, and that of the largest male geese can reach 9.5kg. The average weight of female geese is 5.-6. kg. 2. Strong foraging ability, rough feeding tolerance, mainly grass and less material consumption. 3. Good meat quality, making "roast goose" and "wax goose", fresh and delicious, and unique scenery. 4. High cashmere yield, large pile and good elasticity. 5. Goose skin can be tanned into fur, which is soft and fluffy and has good warmth retention. 6. The posture is high and the voice is loud. Selection of goslings: Healthy goslings hatch for 3 days, weigh 8 ~ 1 g, and have soft abdomen, good umbilical contraction, clean anus, full absorption of yolk, stable standing, lively action, strong cry, bright coat color and eyes full of spirits. When the gosling is lifted by holding its neck, its feet can contract quickly and struggle vigorously. 2. Preparation for brooding: Before brooding, the brooding room and brooding equipment should be prepared. The brooding room is warm, dry, clean, well-lit and well-ventilated. 3 ~ 7 days before brooding, the brooding room and brooding utensils should be thoroughly disinfected. 3. Drinking water and feeding: 24 hours after the goslings are hatched, they should be given 3×1-6 potassium permanganate water, fed 6 times a day for 1-7 days old goslings, and fed 8-15 days old goslings 8 times a day, first before drinking. The proportion of compound feed can be adapted to local conditions. 4. Heat preservation and moisture prevention: goslings have poor ability to regulate body temperature, so the temperature of brooding must be regulated. The brooding room should be dry and hygienic, and the padding should be dry and soft, so as to prevent gosling diseases caused by humidity. Second, grazing technology 1. Goose signal: From the beginning of goslings, every time before feeding and grazing, different language signals are sent out to form conditioned reflex, so that geese can be commanded. When grazing, you should choose a good goose so that the goose can move with the whole group. If the first goose does not listen to the command, it should be eliminated in time and another goose should be selected. 2. Choose a good grazing site: Young geese and adult geese should choose a grassland with lush grass, clean water nearby and smooth roads. 3. Reasonable grazing time: goslings will start grazing after 5 days old, and grazing should be carried out at 8-1 am and 4-6 pm with mild weather and no wind and rain. 4. Reasonable supplementary feeding: After the goslings come back from grazing, they should be reasonably supplemented with concentrate according to their food intake. Yangzhou Goose Yangzhou Goose is known as the first new goose species in China. This is a planned project issued by Jiangsu Science and Technology Commission in the Eighth Five-Year Plan and the Ninth Five-Year Plan. Yangzhou Goose has the following characteristics: firstly, Yangzhou Goose has the advantages of both male and female parents. It has fast growth speed, good meat quality and high reproduction rate. Generally speaking, 7-day-old geese can reach 3.3 to 3.5 kilograms, which is 27.8% higher than Taihu Goose. The second point is that the offspring have good meat quality, and the protein content of meat is 1% higher than that of its parents. Third, its egg production level is relatively high, the annual egg production can reach 72 to 75, and it can produce 62 to 64 goslings. It is also resistant to rough feeding, and it can eat any grass when grazing. First, the origin of Yangzhou Goose. China's goose breed resources are rich and diverse, and their adaptability and production performance are different. There are seed geese, Huoyan geese, which are famous for laying eggs in the northeast, Ili geese adapted to the cold plateau climate in Xinjiang in the northwest, lion geese with large body and fat in Zhanjiang coastal area of Guangdong in the south, Sichuan white geese with fast growth and many eggs in Chengdu and Chongqing in the southwest of the west, Xupu geese with good liver performance in Central China and Hunan, Taihu geese with good meat quality and many eggs in Jiangsu, and Zhejiang geese laying eggs all year round in Zhejiang and Anqing. These local varieties not only have wide natural ecological adaptability and strong resistance, but also contain great genetic variation and selection potential. However, due to the long-term existence of goose industry in China in the form of rural sideline, mainly grazing, extensive feeding management and low production level, many varieties have not been scientifically and systematically selected, and the production performance within varieties is quite different among individuals and lacks consistency. In addition, due to the long-term scattered feeding by farmers, most goose breeds in China have strong nesting ability and few eggs, such as Lionhead Goose and Anhui Wild Goose, which have strong nesting ability and only lay 25-35 eggs a year. Goose industry is a traditional characteristic industry in our city, which is rich in natural resources, strong technical foundation, long-term accumulated practical experience and strong market demand, but lacks ideal fine varieties. In order to improve the efficiency of raising geese, increase farmers' income, meet the market demand, and promote the development of animal husbandry and even the whole rural economy, Sichuan Longchang Goose (Sichuan White Goose) was introduced to our city in 199 to conduct research on its development and utilization. In 1996, under the auspices of Professor Zhao Wanli from Yangda Animal Husbandry and Veterinary College, Yangda College of Animal Husbandry and Veterinary Medicine and the former Municipal Bureau of Multi-management (now the Agricultural Bureau) began to use Longchang Goose with fast growth, more eggs and no nesting, Taihu Goose with good meat quality, more eggs and no nesting, and measured combining ability, selected better combinations for backcrossing and backcrossing, and then screened the best combination for generation breeding. So far, it has entered the sixth generation. At the same time, related basic research, exploring new breeding theories and methods, research on the early growth and development law of Yangzhou goose, research on the nutritional needs and digestive mechanism of goose, research on the relationship between the changes of some hormones in the plasma of young geese and their growth performance, research on the correlation between chromosome karyotype and banding analysis of Yangzhou goose and its production performance, and research on the comprehensive prevention and control technology of goose diseases are carried out around the breeding of Yangzhou goose. The breeding of Yangzhou Goose was listed as a key project in the Eighth Five-Year Plan and the Ninth Five-Year Plan by the Provincial Science and Technology Commission. After more than ten years of painstaking research and hard work, a new local excellent goose species was bred, which was officially named Yangzhou Goose after being approved by the Provincial Poultry Variety Committee in August 22. Second, the characteristics and development status of Yangzhou goose 1. The characteristics of Yangzhou goose. Yangzhou Goose is a new breed bred by using domestic goose resources for the first time in China, and it is an ideal medium-sized goose breed. Measured by the National Poultry Production Performance Testing Station, Yangzhou Goose has moderate body shape, good uniformity and stable genetic performance. Meat goslings grow fast in the early stage, are resistant to roughage, have strong adaptability, delicious meat, high muscle protein content, fine muscle fibers, rich intramuscular fat, low water content, high processing yield and good palatability; Under the condition of grazing and supplementary feeding, the average live weight of 7-day-old geese is 3.49 kg, and under the condition of house feeding, the average live weight of 7-day-old geese is 4.2 kg. Breeding geese have good reproductive performance, with an average of 71.39 eggs laid during the laying period, and the fertilization rate and hatching rate of breeding eggs are above 9%. The conclusion of the measurement is that "the growth rate of Yangzhou geese has reached the advanced level at home and abroad, and the goose breeding has reached the advanced level in the world". 2. Development status. Yangzhou Goose has two breeding bases, namely Yangzhou Goose Breeding Center in Jiangsu Province and Yangzhou Goose Breeding Farm in Gaoyou City. There are 5, basic breeding groups, 5, core groups and 4 families. At the same time, some expansion farms have been established to expand the breeding group of 2, geese. In addition, other excellent varieties are being introduced, paternal lines are being cultivated, and specialized lines and hybrid lines are being established. The effect of experiment and popularization of Yangzhou goose in the breeding process is also very remarkable. So far, in addition to the promotion in this city, it has been successfully promoted in Xuyi, Yancheng, Hongze, Wujin, Zhenjiang, Zhangjiagang, Dongtai, Xinghua and more than ten provinces and cities such as Shandong, Henan, Shanghai, Heilongjiang and Anhui. Songqiao Town, Gaoyou City is one of Yangzhou Goose Breeding Bases. In recent years, the town party committee and the town government have made great efforts to promote Yangzhou Goose, and put forward that goose industry will revitalize the town, raising more than 5, Yangzhou Goose every year. Last year, through attracting foreign investment, we invested 5 million yuan to set up a "Tiange" goose processing factory, and some factories directly signed an agreement with farmers on Yangzhou goose breeding, which was purchased at a protective price. Yangzhou Goose was introduced to gongyi city, Henan Province. After several years of trial and promotion, they thought that Yangzhou Goose adapted to the natural ecological environment and relatively extensive feeding and management conditions in the vast area of Huanghuai River Basin, and the early growth rate of young geese and the laying of eggs of breeding geese were higher than those of Sichuan White Goose. Introduced from Huishan, Shandong Province, breeder geese lay 77.6 eggs on average during the laying period. The natural mating and fertilization rate reached 87.6 ~ 91.2%, and the hatching rate was about 85%. They believe that Yangzhou Goose is indeed an excellent goose species, with rough feeding tolerance, strong foraging, wide adaptability and strong disease resistance, suitable for grazing or captivity, and the broiler geese raised in the early stage grow and develop rapidly. Goose breeders have many advantages, such as laying more eggs, large eggs and good reproductive performance, which are well received by breeders. Ten news media and professional magazines, including Xinhua Daily, China Animal Husbandry and Fishery News, Science and Technology Daily, Yangzi Evening News, China Poultry and china national radio, have made special reports on Yangzhou Goose due to its high quality and high yield germplasm and obvious economic benefits, which have generated great repercussions in the society. At present, 24 provinces (cities) all over the country have asked for the introduction of breeding, and the demand for letters and telephones is constant, so the market demand is very large. 3. Accelerate the development of Yangzhou Goose 1. Continue breeding to improve the production performance of Yangzhou Goose. (1) expand the family. The number of families has been expanded from the current 4 to 16, and 1,2 geese have been raised. (2) Introduce 2-3 provenances, establish paternal lines, establish 2-3 specialized lines, select the best combination through the determination of hybrid combining ability, and cultivate and establish hybrid matching lines. (3) Make a good record of family files, analyze and sort out the data, and strive to pass the examination and approval of Yangzhou Goose by the National Poultry Variety Committee as soon as possible. 2. Run Jiangsu Yangzhou Goose Breeding Center well. Based on Yangzhou Goose Breeding Farm, make full use of the advantages of natural resources, varieties and market technology in Yangzhou, and gradually establish and improve the breeding system of Yangzhou Goose, and undertake the conservation, breeding, seed production, expansion and demonstration of Yangzhou Goose. This year, the center will invest about 3 million yuan to complete the main infrastructure tasks of the goose breeding farm, including 4 family goose houses, 4 experimental goose houses, 1 brooding room, 4 breeding goose houses and kang incubation. Through several years' efforts, the goose breeding farm will be built into Yangzhou goose demonstration park. 3. Accelerate the promotion of Yangzhou Goose. Set up 1~2 Yangzhou goose breeding farms in every county (city) in the city, and at the same time set up more than 1 breeding farms inside and outside the province, and each breeding farm will raise .5 ~ 1, parents. In addition, a number of breeding farms and specialized goose breeding households will be established, and efforts will be made to make Yangzhou geese account for more than 8% of commercial geese through the "Tenth Five-Year Plan" or even a little longer. 4. Actively promote the supporting technology of Yangzhou goose feeding. In particular, planting grass to raise geese, incubating in autumn and raising in winter, intensive breeding and disease control techniques for geese. It is necessary to strengthen training and do a good job in typical demonstrations, so that more breeding units and individuals can master the knowledge and production skills of raising geese skillfully, mobilize their enthusiasm and improve the efficiency of raising geese. 5. Vigorously promote the industrialized management and pollution-free breeding of Yangzhou geese. Pay attention to cultivating leading processing enterprises and specialized wholesale markets of goose industry, develop various cooperative economic organizations or associations for raising geese in rural areas, train farmers' brokers, organically combine breeding and processing, production and market, and actively create conditions to form a joint fleet-Yangzhou Goose Industry Group to further improve the degree of organization and socialization of Yangzhou Goose Industry. At the same time, establish a pollution-free breeding base for raising more than 5 thousand Yangzhou geese in 1 years. One base is Yangzhou Goose Park, which integrates goose breeding, kang incubation, commercial goose breeding, feed production (including green feed) and commercial goose processing and sales. It is necessary to strengthen the monitoring of the base environment, including soil, water source, atmosphere, etc., monitor the inputs, including seedlings, feed, and drugs used for disease prevention and treatment, and conduct breeding in accordance with the Technical Specification for Yangzhou Goose Breeding, so as to further improve the quality and safety of Yangzhou Goose products, improve market competitiveness, expand market coverage and promote the development of Yangzhou Goose.
