Feeding and management techniques of egg-laying geese

The purpose of raising egg-laying geese is to obtain large quantity and good quality goose eggs, but the goose has a long feeding period, large feed intake and less annual egg production. In the process of feeding, how to improve egg production and egg fertilization rate is the key to raising egg-laying geese. Due to the different breeds of geese, the maturity period is also different. The production time of small geese is 150-180 days, and that of large geese is 210-240 days. The egg production of female geese changes with the increase of age, the egg production peak is in the second to third year, and the egg production begins to decrease in the fourth year, but a small number of geese can maintain the egg laying peak for 4-5 years. Therefore, egg-laying geese should be composed of 1-year-old geese, 30% of 2-year-old geese, 25% of 3-year-old geese, 20% of 4-year-old geese, 15% of 5-year-old geese, 10% of 5-year-old geese, in order to ensure that geese have a higher egg production and a more balanced egg production over the years.

In the process of raising egg-laying geese, house feeding should be given priority to and grazing should be supplemented. The method of timing and non-quantitative feeding was adopted to satisfy the supply. The feed should be diversified, the ratio of cereal to crude bran is 2:1, and more concentrate should be added every night. 0.20kg / day for large egg geese and 0.150.20kg for small egg geese. When feeding, you must follow the rule of feeding green feed first, then concentrate, and then rest. The first time, the mixture was fed at 5-7 am, then the concentrate feed, the second time at 10: 11 noon, and the third at 5-6 pm. At the peak of egg production, geese must be fed well, especially in the later stage of egg laying. A little carelessness can lead to the suspension of production and the beginning of molting, so they can be fed several more times and fed night food or let them eat freely.

Shed feeding should also have a certain amount of grazing exercise time, so that geese can get sufficient foraging, light, bathing and mating. Choose a clean pond for geese to bathe, drink and mate. In order to facilitate breeding geese to mate, the pond water depth should be about 1 meter.

Under the condition of artificially controlled house feeding, the laying geese matured earlier and laid eggs neatly. The egg production is high and stable.

Most female geese lay eggs at 2-8 in the morning. The duration of laying eggs is not consistent enough, some eggs are laid the next day, some are laid for two days in a row, and some are laid two eggs in a row every one or two days. During the laying period, the temperature in the house is maintained above 4 ℃. The method is to add door and window straw curtains and wind barriers. Geese are sensitive to light, and supplementation of light can increase egg production, especially for varieties with low egg production, and egg production increases faster after supplementation of light. Supplementary light plus natural light, up to 12-14 hours a day, the effect is better, the illuminance per square meter goose house area is 2-3 watts, if the house area is 20 square meters, can add a 40-60 watt electric lamp.

Geese can also graze mainly during the laying period, and generally should be placed in the pasture after laying eggs in the morning, but feeding should be considered according to natural feed, goose feed intake, egg shape and so on. The laying goose moves slowly, so it is necessary to choose a flatter pasture nearby for grazing. Grazing should be slow to drive, fast drive geese easy to fall or yolk fall into the abdominal cavity and cause peritonitis. If the weather is hot, let the geese sleep outside the sports ground, rush back to the house when it rains, and prepare enough water for them to drink. The goose house should be cleaned once a day to keep it clean, especially the egg nest mat should be dry.

Goose flocks should be checked before grazing every morning. If individual geese are found to be singing uneasily, full belly, flat tail feathers, expanded cloacal cavity and slow movement, the goose that wants to go to the nest should be caught and touched if there are eggs, it should be left in the circle and go out for grazing after laying eggs. The goose has the habit of going back to the nest to lay eggs. If the goose does not eat grass, stretches her head and neck, cries and "loves the nest" during grazing, she should drive the goose back to the circle to lay eggs. In addition, some of the first-laying goose will not return to lay eggs in the circle. If they are found to lay eggs in the grass, they will bring the goose back to the nest together with the eggs laid. After 1 or 2 times of training, the goose can get used to laying eggs in the circle. When grazing, geese eat 7-8% full, they should be driven to the edge of the pond, let geese take a bath, drinking water and mating, which is conducive to improve the fertilization rate of goose eggs.

When the female goose reaches the later stage of laying eggs, the number of eggs decreases and the quality of the eggshell becomes worse. At this time, it is necessary to feed more concentrate feed, which accounts for 70 to 80% of the total diet, which can prevent a significant decrease in egg production or stop production.
