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.
Effective protection against feathers
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 litter management
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.
Artificial lighting
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 winter must be sufficient and even. The last is to feed the trace elements that promote feather growth after 20 days of age.
