First, the choice of brooding mother geese The mother geese used for brooding have strong nesting ability. It is best to use geese that have been used for 1 year or more to have nesting habits. If you use a new mother goose without hatching habits, you can set dummy eggs to let them hatch. When the mother geese quietly hatch, put the eggs into the nest. If there are no brooding geese, they can be replaced with hens, but the amount of hatching should be reduced. In the breeding season of geese, it is generally not necessary to try hatching, because at this time there are many mother geese one after another, and at any time can replace the mother geese that are not strong enough to hold. The mother goslings, which are usually held, usually begin to hug every 9 to 14 eggs. At the end of each litter, the female goose begins to hold the nest of grass mats. Even when the eggs are laid, the feathers of their own breasts cover the eggs, which is a sign that they begin to embrace the nest. Second, the preparation of nest nest nest should choose a quiet, sheltered, darker light environment, can be directly used hatch nest hatching, can also be used shorter dwarf made of 45 to 50 cm in diameter nest hatch. Put clean and soft mat grass on the nest, first put the "lead", let the mother goose familiar with the brood and then put 10 to 12 goose eggs. It is best to hatch at night to help the mother goose quietly hatch. Third, the incubation period of operation and management Identification of cuddling geese: 2 to 3 days after hatching, observe the performance of mother goose eggs. Any person who is uneasy and frequently enters and exits must be promptly removed and replaced by the mother goslings. 2. Artificially assisted turning eggs: Although the mother geese turn their eggs, they are uneven. In order to increase the hatching rate, it is possible to manually assist the turning of eggs 2 to 3 times a day. The eggs in the center of the nest are placed on the side of the nest, and the eggs in the nest are placed in the center of the nest. Because goose eggs are bulky, have low water content, and are thick and sticky, so when turning the egg, the angle should be large so that the embryo can rotate. It is better to turn 55 back and forth, that is, turn the egg 110. According to reports, the goose egg rotates 180 to obtain a better hatching effect. 3. Keep the crotch clean: When you turn the egg, replace the bedding that has been contaminated with faeces. 4. According to the egg: Incubation period is generally 2 to 3 times, according to the egg in time to eliminate lean, dead embryo eggs. Immediately after hatching the eggs, the excess goslings can either hatch new eggs or wake up and let them lay eggs. 5. On the breeding and management of the nest geese: mother geese hold nests for one month, the body's nutrients consume a lot, gradually weight loss, weight decreased significantly. If the husbandry is not properly managed, the female geese will leave the nest halfway and individual geese will even die. In the process of hatching, it is necessary to regularly leave the nest, feeding, drinking, activities and playing water: (1) 1st to 10th days, leaving the nest on the next day, the first few times need to artificially grasp the goose from the nest, After the conditioned reflex is established, the geese will leave the nest automatically. Each time you leave the nest for 30 to 40 minutes, let it feed and feed it into the water. After the geese defecate and dry their feathers, they will be driven back to their nests and continue to hatch. While the mother goose is away from her nest, the surface of the egg should be covered with insulation material such as thin cotton wool. (2) On the 11th to the 27th day, it was changed from the nest once a day in the morning and the time from the nest could be extended to 40-60 minutes each time. (3) On the 28th to the 31st days, in order to prevent the goslings from breaking or smashing the embryonated eggs due to the large size of the goose before hatching, the embryos should be promptly transferred to the bamboo baskets with appropriate coverings. Insulation, at the same time forced the female goose away from the nest, grazing with the group, to strengthen feeding. 6. Auxiliary hatching: If the gosling has a long shell and fails to hatch, artificial midwifery can be carried out and the head of the gosling can be pulled out of the shell. But it must be carried out when the allantoic wither, if any bleeding during midwifery, it should stop immediately.
