Second, the key technologies
(a) Choose good geese in the spring hatchling goslings, choose large, robust breeding geese. After 70 days of gosling rearing, goslings with a body weight of more than 3 kilograms, a tightly-knit body with two wings, a tight and shiny feather, a wide round buttock, and a tail that is not wavy are required for breeding. Geese are required to have a tall and well-proportioned body, and the mouth is medium and thick. The eye is convex, the neck is slender, the call is loud, the legs are thick, the distance is wide, and the penis is normal.
(2) In the production stage, summer maize, wheat, and bran are mainly used to cultivate the summer, and each of them feeds about 100 grams three times a day, and the other supplies 300-500 grams of green material. In the autumn, only feed is maintained. Each day, up to 90 grams of whole bran and wheat bran are fed. In the winter and early summer, the egg is fed 3 to 4 times a day, and it is timed to quantify, eat freely, and eat enough to drink. The use of rice, corn, wheat, etc. as the main raw material, and the reduction of bran; and adding 300 grams of salt and 1 kg of bone meal per 100 kg of material, so that the mother geese can see the eggs in early winter, before the Spring Festival, it is just in time for hatching. Best season.
After the geese are put into production, they are grazing twice a day in the morning and once in the afternoon, each time for 1 to 2 hours, so that the geese can have sufficient time for activities. The geese have the habit of laying eggs back and grazing should be near the poultry house. If you see the mother goose do not eat grass, stretch the neck, howling, is the "love nest" performance, to rush back to homes, after several guides, the mother will automatically return to the nest eggs.
Gooses are waterfowls and mostly mate on the water. Male geese have the highest sensation in the morning, so they should release water at least 4 times a day and put more in the morning so that the mother geese can be given the opportunity to reconstruct the fertilized eggs.
(3) The compulsory moulting goslings during the production stop period each year produce eggs until the early summer, and the egg production starts to decrease. Most goose feathers dry up and enter the production stop period. At this point, the diet should be changed from concentrate to coarse material, and transferred to grazing-based feeding and management, to reduce the level of nutrition to urge the mother geese to consume fat in the body, so that feathers further dry, easy to fall off. The number of feeds during this period should be gradually reduced to once a day, every other day to 3 to 4 days, but can not stop the water. After 13 to 15 days, the goose body is thin, weight is reduced, and dryness of the main wing feathers and the main tail feathers appear dry. The test is performed in a detached state with no meat shavings, and artificial pullout can be performed. Feathering artificially can shorten the moulting time than natural moulting, so that the mother geese can restore egg production earlier. Moreover, the production of eggs is more tidy after moulting, and the quality of the eggs is better.
Plucking feathers should be selected on a sunny day, when the goose is fasting. Hold the two wings of the goose with one hand. Open the wings with the other hand. Pull the main wing feathers and auxiliary wing feathers along the direction of the growth of the main wing feathers. Then pull the main tail feathers. On the day after the plucking, the geese should be housed in the stadium for feeding, watering and rest, and the geese should not be allowed to swim under the water to prevent bacterial infection and cause inflammation of the pores. After a period of plucking, due to poor adaptability, wind, rain and sun exposure should be avoided.
After plucking, in addition to strengthening grazing, the male and female goose feathers should grow according to the speed of male and female goose feathers as appropriate, so that the body feathers of the male and female gooses grow more uniformly, so as to restore the body condition of the laying eggs as soon as possible and enter the next round of egg production and breeding stages.
As the geese mature later, the hens have the highest egg production in the first 4 to 4 years after laying. Therefore, the goslings usually stay for 4 to 5 years. After the end of each year, the geese must be eliminated from the culprits. High-yielding geese enter the production phase.
