Technical video of wild goose breeding

Abstract: wild geese are used in meat, eggs, velvet and medicine, and their chest and legs are well muscle. although the meat fiber is thicker than that of wild ducks, the meat is delicious and tender after cooking. As high as 20.98% protein and 10.62% fat, it is rich in vitamins and trace elements needed by the human body. Wild goose feather can make badminton, feather fan and feather pen, and down can protect against cold and warmth. At present, wild goose breeding has just started.

Wild goose, also known as wild goose, is the general name of wild geese, gray geese, bean geese and black geese in the duck family. Large migratory birds are second-class protected animals in the country. Its sex is gentle, easy to raise, small food intake, strong herbivore, fast growth rate, feed-meat ratio of 2.5 to 1, generally feeding for 60 days or so, the weight can reach 4-5 kg, the weight can reach 8-10 kg. Wild geese set meat, eggs, velvet, medicine in one, its chest and legs are muscular, although the meat fiber is thicker than the wild duck, but the meat is delicious and tender after cooking. Protein up to 20.98%, fat 10.62%, rich in vitamins and trace elements needed by the human body. Wild goose Ling can make badminton, feather fans and feather pens, and down can protect against cold and warmth. At present, goose breeding has just started, coastal cities and some national game markets are in short supply, the prospect of breeding wild geese is good, now the wild goose breeding technology is introduced as follows.

The living habits of wild geese

Geese have strong adaptability and are omnivorous waterfowl. They often inhabit watersides or marshes where aquatic plants grow in clusters, and feed on some non-toxic and odorless weeds, grasses, cereals, snails, shrimp and so on. Sometimes I also wander in the lake and like to mate in the water. Be gregarious and good at fighting. 10-20 live together in small groups in spring, and hundreds look for food and roost together in winter. When perched, there are geese on guard, find abnormal, scream loudly, escape in groups. When living in groups, through fighting to determine the rank sequence, the prince geese have the right to give priority to feeding and mating.

Reproductive characteristics of wild geese

1. Laying eggs: it takes 3 years for wild wild geese to mature sexually, the monogamy of one male and one female, and pairing for life, and both parents are involved in the breeding of young geese. When raised in captivity, it reached sexual maturity in 8-9 months, and the ratio of male to female was 1:2-3. Wild geese are in estrus in spring and mate in the water. During courtship, the male goose swims around the female goose in the water, constantly swinging his head up and down, stretching his neck for a fake drink while swimming to the female goose. When the female geese make the same response, the male turns behind the female, and the female sinks slightly, and the male mounts on the female's back and pecks the female's neck feathers with his beak and vibrates his wings for mating. After mating, they swim in the water or come to the shore to comb their feathers. Female geese begin to lay eggs 10 days after mating and lay one egg at intervals of 2-3 days. The annual egg production is about 15 in the first year and 25 in the second to the sixth year. Each egg weighs 150 grams.

2. Hatching: small-scale wild goose farms can allow geese to hatch by themselves, or they can be hatched by female geese. Large-scale wild goose farm needs to be hatched artificially, and the incubation period is 31 days. Fresh breeding eggs with suitable size, normal shape, color and clean surface were selected and disinfected by formaldehyde fumigation (15 grams of potassium permanganate and 30 ml formaldehyde per cubic meter, 24 ℃-27 ℃ at room temperature), then preheated in the incubator (22 ℃-24 ℃) for 6-8 hours before hatching. The temperature was 38.3 ℃-39.0 ℃ in the early stage, 37.5 ℃-38.0 ℃ in the middle stage and 37.0 ℃-37.5 ℃ in the later stage. The relative humidity is 75%, 80%. Turn the egg every 2-3 hours at an angle of 90 degrees. The movement should be light, steady and slow, so as not to cause rupture of blood vessels in the yolk membrane, separation of the allantoic chorion from the eggshell membrane, and death of the embryo. In the later stage of hatching, the cold eggs are cooled 2-3 times a day, and the temperature of the cold eggs is 25 ℃ ~ 27 ℃. If the room temperature is too low, the development will be affected by "flashing eggs". The eggs need to be illuminated twice in the process of hatching. on the 8th and 28th day after hatching, the azoospermic eggs and middle-dead eggs were detected, and the embryonic eggs were moved into the machine after the second irradiation. The hatching begins on the 30th day and ends on the 31st day.

The conditions of the wild goose house

The wild goose house should be warm in winter and cool in summer, sunny and well ventilated. It can be divided into nursery house, fattening house and wild goose house. The nestling house should be insulated and moistureproof, the fattening house should be equipped with scaffolding, next to the trough and drinking fountain, the wild goose house should be larger, there should be land and water sports grounds outside, and a 1.8-2-meter purse seine should be set around the sports ground. The land sports ground should be dry without stagnant water, covered with sand 5 cm thick, shaded by trees or crops, and the purse seine of the water sports ground leads directly to the bottom of the water. There should also be grasslands with abundant plants for grazing.
