How to breed geese artificially

Wild geese, also known as wild geese, swans, large migratory birds, are second-class protected animals in the country. The wild geese are enthusiastic and can inspire their companions and encourage their flying companions with their calls. Wild geese belong to the class Ornidae and Anatidae, which is the general name of all species of the subfamily Yeninae. Common in China are wild geese, gray geese, bean geese, white forehead geese and so on. The geese are made up of six, or in multiples of six. The geese are families, or aggregates of groups. Let's introduce how wild geese breed artificially.

The sexual maturity of wild wild geese takes 3 years, a male and a female monogamy, and lifelong pairing, both parents participate in the rearing of young geese. When reared in captivity, sexual maturity was reached in 8-9 months, and the male-female ratio was 1-1-2-3. 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 geese turn behind the female geese, and the females sink their bodies slightly, and the males mount on the female's back and peck the feathers of the female's neck with their beaks, vibrate their wings and mate. 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, weighing about 150 grams each.

Wild geese nest in the wild in spring. Generally, they lay 25 eggs and hatch for 31 days. Under the condition of artificial domestication, the suitable ratio of female to male is 1:1. They usually mate after the Spring Festival and begin to lay eggs 10 days later, laying 1 egg every 2-3 days, about 15 eggs in the first year, and about 25 eggs in the next 2-6 years.

Artificially farmed geese lay one egg every 2-3 days and 90,120 eggs a year. The management mode and incubation conditions are similar to those of domestic ducks and geese, except that the frequency and time of hatching eggs are slightly increased. For the breeding units with large scale and large number of eggs, it is best to use hatching equipment for artificial hatching.

Incubation

Small-scale wild goose farms can allow geese to hatch by themselves, or they can be hatched by goose instead. 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 sterilized with formaldehyde fumigation (15 grams of potassium permanganate per cubic meter, 30 ml of formaldehyde at 24 ℃-27 ℃ at room temperature), then preheated in the incubator (22 ℃-24 ℃) for 8 hours and then hatched. 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 once every 2Mel 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 incubation, the cold eggs are cooled for 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.

Wild goose house condition

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 nursery should be insulated and moistureproof; the fattening house should be equipped with scaffolding with troughs and drinking fountains; the wild goose house should be larger, with land and water sports grounds outside, and a 1.8-meter-high purse seine around the sports ground. The land sports ground should be dry without stagnant water, covered with sand 5 cm thick, and shaded by trees or crops; the purse seine of the water sports ground should lead directly to the bottom of the water, and the mesh should not be drilled out of the wild goose head. There should also be grasslands with abundant plants for grazing.

Management methods of breeding period of wild geese

The main results are as follows: 1. The mating period is about June to August after the eggs are laid every year. During the period of mating, in order to make the geese change their hair neatly, one is to control the feed, each feather is only fed 0.5 to 12 taels per day, and the good fodder is not replenished, which promotes the geese to change their hair neatly. Second, you can pull out two wings of hard feathers, three on each side, a total of six, leaving one of the longest hard feathers on each side. (keep the long feathers on the tip of the feather) after the hair is changed, the pasture is fed properly, and the pasture is not fed much, about 2 taels a day. It is best to feed the full price material and the rice.

2. To raise wild geese in January of the Gregorian calendar every year, it is necessary to strengthen nutrition about a month before laying eggs. It is best to feed a full-price diet with comprehensive nutrition, about 3 taels per feather per day, so that the geese are physically healthy but not too fat. It will be fed properly in February, about 4 taels per feather a day, and one meal in the morning and one in the evening. It is best to feed with granule full price material, if the mixed powder is best fed with water, add water to mix well and knead into a ball, it is appropriate to let go, so as to avoid sticking throat and waste.

3. Raising wild geese and breeding geese needs to be dewormed every two or three months, and the last time of the laying period is carried out one month before laying. Be vaccinated against disease before laying eggs. Generally, the goose plague vaccine is injected one month before the goose opening, and the bird flu vaccine is injected the second week.

4. To raise wild geese, it is necessary to build egg nests for breeding geese for half a month before they are planted. The egg-laying nest can be grown with a thin plywood or plywood nail about 5 inches wide to grow 1.1 feet, and a non-bottomless, uncovered shelf with a width of 1 foot. Each shelf is covered with straw, or straw is woven into round pots, cartons, plastic pots, and then covered with clean straw to form an egg nest.

5. after the beginning of egg laying, in order to prevent geese from laying eggs outside, it is necessary to gradually increase the time of house feeding and postpone grazing, which is not grazed until 10:00 to 11:00 before the peak of egg production. Even at 11:00 in the morning, some geese lay their eggs outside the shed, which requires using four 4-foot-long bamboo or branches near the shed to tie one end with a rope, then spread the four feet, cover the top with straw tied to one end, and cover the bottom with clean straw to form an egg laying nest, and a dozen or so near each shed.
