Do a good job of ducklings insulation and epidemic prevention
Winter disease factors often cause uneven growth of ducks, mainly to solve the problem of insulation in ducklings. During the first 3 days of the brooding period, the temperature must be kept above 30°C to ensure complete absorption of the yolk of the ducklings and there will be fewer rearing issues. Ducklings need to adapt to the temperature step by step, can not let the North wind blow directly to the night shed temperature needs to be higher than the daytime temperature. If the duck house is sealed too tightly, the concentration of ammonia gas in the house will be too high and it will be more likely to cause respiratory diseases. Winter cold is common in ducks. Adding some cold-prevention medicines at the same time before 20 days of age, and then doing a good job of vaccination to strengthen environmental sanitation and disinfection can effectively reduce the incidence of diseases.
Do all kinds of adjustments to prevent the phenomenon of duck feathering
In winter, when the weather is dry, the phenomenon of feathering is obvious when breeding on the Internet. Because the wind cannot be blocked, the north wind blows directly to the ducks, causing excessive stress and causing severe feathering. The problem of litter has also had a major impact. In practice, it has been proven that wood lice are significantly more effective than bedding with litter. An effective way to solve the phenomenon of plume feathers: After all the animals are changed to the ground, the duck houses should be ventilated during the day, windshields should be put down at night, and wind equipment should be used to reduce stress, which can effectively reduce the occurrence of plume.
Strengthen management work and reduce the appearance of ducks
The ducks raised in captivity are prevented from having too little, too thin, too dirty and too wet in the cold winter. Because the breeding site is moist and muddy, the sheds in the sheds are too thin or there is no litter at all, which eventually causes the ducks to sleep on the cold ground or the soiled excrement of litter. This not only affects the weight gain, but also the chest and abdomen of the ducks. Feathers easily fall off, causing a "light duck" phenomenon. This will lead to a decrease in the appearance quality, affect the sales and the final carcass quality, and reduce the economic benefits of ducklings. Therefore, strict preparations must be made for pre-emergence preparatory work. When litter is insufficient, no seedlings are allowed to enter the seedlings. In the middle and late period of cultivation, the excrement will be promptly removed, litter replacement and replenishment will be performed in order to keep the site dry and clean; the confinement site is The design should have a certain slope to facilitate drainage; reduce the rearing density, allow the ducks to have a dry and comfortable environment, improve their physique, and ensure good health. Only in this way can the weight gain be fast and the carcasses have good meat quality.
Artificially increase light, prevent ducks from "short hair and water"
Due to the short growth cycle of ducks in winter, if the water is too short, it will affect the time to market, and the long-term breeding cost will increase. Therefore, it is necessary to devote enough effort to the feather growth of winter ducks. Light time, intensity, and trace element intake are also closely related to feather growth. In winter, natural lighting conditions are poor and time is short, which often results in slow growth of duck feathers. Therefore, in the winter duckling process, artificial light must be used. The light is 24 hours, and the lights in the winter must be sufficient and even. The last is to feed the trace elements that promote feather growth after 20 days of age.
