The geese have a combination of meat, eggs, cashmere and medicines. Their chest and leg muscles are well-developed. Although the meat fibers are thicker than the wild ducks, they have a delicious flavour and are tender and tender after cooking. Protein is up to 20.98% and fat is 10.62%. It is rich in vitamins and trace elements needed by human body. Wild Goose can make badminton, feather fan and quill, and down can keep warm. At present, the breeding of geese has just started, and some game markets in coastal cities and the whole country are in short supply. One young bird geese 600-800 yuan and young geese 100-150 yuan. The prospect of breeding geese is good.
1 The habits of wild geese The geese have strong adaptability. They are omnivorous water birds and often inhabit the waterside or swampy land where aquatic plants are clustered. They feed on some weeds, pastures, cereals, snails and shrimps that are non-toxic and have no special smell. Sometimes wandering in the lake, like to mate in the water. Strong gregarious, good fight. In the spring 10-20, there are only a small group of animals. In winter, hundreds of people will be eating and inhabiting together. When they settled in Suqian, wild geese warned and found abnormalities. They screamed loudly and escaped in groups. When gregarious, through the battle to determine the rank sequence, prince geese have the priority to feed, mating power.
2 Breeding characteristics
2.1 It takes 3 years for mature wild geese to mature. It is a single spouse with a male and female, and is paired for life. Both parents are involved in nurturing young geese. When artificial breeding, 8-9 months to reach sexual maturity, the ratio of male to female 1:2-3.
Wild geese estrus in spring and mate in water. During the courtship, the male geese swimming in the water around the female geese, and constantly swinging their heads up and down, while extending their necks and drinking water to swim to the female geese. When the female geese also make the same movement response, the male geese go to the back of the female geese, and the female geese will sink slightly, and the male geese will climb onto the female goose's back and cover their female geese and neck feathers with their mouths to shake the wings. Mate. After copulating, you can play in the water or comb feathers. The female geese go on to lay eggs 10 days after mating and produce 1 egg every 2-3 days. The annual egg production is about 15 in the first year, 25 in the second year to sixth year, and the egg weight is 150 grams each.
2.2 Incubating small-scale geese can allow the geese to hatch on their own, and can also be used to hatch the goose. Large-scale geese farms require artificial incubation and the incubation period is 31 days. Select fresh eggs with suitable size, normal egg shape, and color that meet the requirements of species and clean surfaces. After disinfection with formaldehyde fumigation (add 15 g per cubic meter of potassium permanganate, 30 ml of formaldehyde, and room temperature of 24°C-27°C), Put it in the hatching room (22°C-24°C) for 6-8 hours to warm up.
The pre-incubation temperature ranged from 38.3°C to 39.0°C, the medium range from 37.5°C to 38.0°C, and the later period from 37.0°C to 37.5°C. Relative humidity is 75%-80%. Turn eggs once every 2-3 hours, the turning angle is 90 degrees, the action when turning eggs should be light, steady, slow, so as not to cause rupture of the yolk membrane blood vessels, chorioallantoic membrane and eggshell membrane separation, causing embryonic death. In the late stage of incubation, cool eggs are 2-3 times a day. The temperature of cool eggs is 25°C to 27°C. If the room temperature is too low, the development will be affected by the "flashing eggs." In the hatching process, the eggs must be treated twice. On the 8th and 28th days after hatching, no eggs and dead eggs should be detected. After the second shot, the eggs are transferred to the hatcher. The hatching began on the 30th day and ended on the 31st day.
3 Yanshun conditions Yanshang require cool winter, cool, sunny, well-ventilated. It can be divided into brooding houses, breeding houses and breeding geese. The brooding house should be insulated and damp-proof; the scaffolding should be provided with scaffolds, next to the troughs and drinking fountains; species of geese should be larger, with land and water sports grounds outside, and a 1.8-2 m high fence around the stadium. . The land sports grounds should be dry and not covered with water. Shop 5 cm thick sand and plant trees or crop shade; the water sports stadium's seine nets should pass through the bottom of the water, and the net holes should not be drilled out of the geese. There should also be a rich meadow for grazing.
4 Breeding of young wild geese
4.1 The first drinking of the “tidal mouth†and the start of eating young geese is called “tidal mouth†or “boiling waterâ€. When the young geese walk freely and begin to forage on the grass, pour 0.01% potassium permanganate solution into a flat-bottomed basin. The water temperature is 18°C-25°C, and the water depth is just to submerge the young goose claw (about 1 - 2 cm) is appropriate, so that young geese to drink water, usually 3-5 minutes, to dip feet not for the degree of wet hair. If the tide mouth is postponed for some reason, 0.8%-1.0% of salt should be added to drinking water, and the amount of drinking water should be controlled so as to avoid poisoning caused by wild goose drinking.
After the “tidal mouth†can be eaten, the open food can be cleaned and soaked with broken rice and chopped vegetables. The broken rice needs to be soaked for 2 hours. The leaves must be cut into thin filaments. The ratio is 1:2-3. The time for eating is approximately 30 minutes. It is advisable to eat up to 80%. After feeding, it is necessary to feed regularly and feed less frequently. Do not feed high-fat diets for 1-3 days. At 4-10 days of age, add some cooked egg yolk, high-quality fish meal, or vegetable protein feeds with low fat content to the feed.
4.2 Insulation and moisture-proof young geese are afraid of the cold, avoid the tide, should pay attention to insulation. The temperature at 1-7 days is 30°C-26°C, 26-14°C at 8-14 days, 24°C-20°C at 15-30 days, and 0.5°C-1.0 in winter or night. °C. The litter cools or changes regularly.
4.3 The group of pressure-reducing young geese should regularly group strengths and weaknesses, eliminate sick and weak chicks, and prevent geese from gathering and crushed to death. The size of each group before the age of 15 days is 30-50, the density is 15-20/sq.m., and the size of each group after the 15th day is 80-100, and the density is 8-10/sq.m.
4.4 If the temperature is suitable for grazing and sewerage, young geese can be grazing on the 4th day of age. The first grazing should select sunny and sunny days, and adopt the principle of “late and late harvest, short time, and a short distanceâ€. 6 times, night feeding back 2-3 times. When the temperature is low, the animals can be grazing for the first time at 10-15 days.
After 7 to 15 days of age, young geese choose to clean the first time the water, the water temperature is 20 °C -30 °C, generally in the afternoon 3-4 hours is appropriate. After the water is released for a few minutes, it is rushed to the shore to allow it to comb the fluff. After the hair is dried, it can be returned to the brooding room.
5 Feeding Management of Zhongyan
One-month-old geese that are sexually mature are known as geese or bred geese. At this time, it has a large intake and digestive ability. It is the period of rapid growth of bones, muscles and big feathers.
5.1 Before the grazing geese grazing should be broken, cut off one side of the metacarpal and phalanges or cut off the extensor digitorum longus extensor digitorum and wrist, wrist wound healing after a week can be grazing. Grazing land should have a sufficient amount of green feed and grain feed. The grazing time should be set in the morning and evening. At noon, they should rush to the shade under the shade of the pool. After each fulness, they should release water. Poor watering conditions can be cut and fed separately.
5.2 Zhongyan, which is reserved for feeding, should be grazing-based, increase the amount of concentrate, reduce coarse material, and encourage the geese to reach sexual maturity in advance. The main feed is bran, mixed with sweet potato, cereal and a small amount of peanut cake, plus 1%-1.5% bone meal, 2% shell powder and 0.3%-0.4% salt.
5.3. The remaining geese and product geese left by fattening and seeding are collectively referred to as fattened geese. Its digestive capacity has become more and more perfect, requiring short-term fattening to achieve twist and optimal weight. The use of upper sheds for fattening and captive breeding can be achieved mainly through adequate feeding, control of lighting, keeping the environment quiet and limiting geese activities and other methods to achieve the purpose of rapid growth and deposition of fat. In fattening feed, 70% of corn, 15% of bean cake, 10% of leaf powder, 4%-5% of wheat bran, and 0.3%-0.5% of salt. Feed 3 times during the day and feed 1 time at night with a density of 3-5/m2. In areas with good grazing conditions, grazing and feeding can be used in combination with fattening. After 25 to 25 days of fattening, the young geese can be slaughtered after reaching the market standard.
Breeding management of 6 species of wild geese
6.1 Preparation period for breeding During the breeding preparation period of the first one month before the start of production, the geese still take grazing as the mainstay, and according to the geese's constitution and the situation of removing new feathers, the materials are fed at the right time to prepare for the production of eggs. The feed is mainly concentrated, about 55%-60%. Male and female were reared separately, male geese were supplemented three times a day, female geese were supplemented twice a day, and inoculated with culled vaccine.
6.2 During the breeding season, the principle of feeding mainly and grazing as the supplement is adopted. The crude protein in the diet is 17% to 18%. It is fed 2-3 times a day and fed at one time in the evening. The mineral feed is properly supplemented. . The water is fully drained, especially in the morning when the male geese have strong libido, so that the geese can enjoy mating on the water. The domesticated geese will nest and lay eggs, and they will leave unlayed wild geese in the house each morning. After the eggs are laid, they will be released and grazing.
6.3 During the discontinued period, the female geese produced eggs until July, when the production of eggs decreased, feathers dried up, and male geese decreased their libido. After entering the production stoppage period, the concentrate is changed to coarse material and then transferred to the rough-grazing period based on grazing. The grazing can be conducted throughout the day without feeding. However, if the grazing conditions are poor or even rainy, appropriate feeding should be done. In winter, mix cabbage, corn stalk powder and grass powder with 20% -30% of cornmeal to maintain and keep the body weight. During the winter season, hot food, warm water, and mildew feed should be strictly prohibited.
