Feeding and management of egg-laying ducks in winter

Winter is coming, the weather is getting colder and the light time is shorter, which is the lowest laying season for laying ducks. If the feeding and management is done well, the laying rate of laying ducks can be maintained at more than 80%; if mismanaged, the laying rate will be significantly reduced. The focus of the management of laying ducks in winter is to keep warm and keep a certain amount of light time.

First, keep warm. Repair doors and windows, block caves and north windows, strictly prevent the invasion of thieves, keep the bedding grass dry, and replace it in time, keep the temperature in the shed above 5 ℃ in the middle of the night, and pay attention to ventilation when the temperature is high.

Second, scientific preparation of diets. Laying ducks need to keep out the cold and lay eggs during the overwintering period, and the energy consumption is relatively large, so it is necessary to appropriately increase the proportion of energy feed such as corn in the feed formula, and increase the feed amount by 10% to 15%. And provide adequate green feed or regularly supplement vitamin A, vitamin D, vitamin E and so on. If each laying duck is fed with 2 grams of lard every day to supplement the energy consumption of the laying duck, it will help to improve the laying rate.

Third, often "dry duck". Ducks were originally released as animals, but they should artificially increase their activity in captivity, and drive ducks in circles every day to prevent ducks from getting too fat, enhance their ability to protect themselves from the cold, promote them to lay more eggs, and leave the sports ground as large as possible. Walk slowly when drying the duck to prevent the duck from being frightened. When it is too cold, dry the duck when it comes out of the shed in the morning to prevent the duck from suddenly cooling down and the duck catching a cold.

Fourth, increase the lighting time. The lack of natural light in winter can easily lead to a decline in the laying rate. A 60-watt light bulb can be installed every 30 square meters in the duck shed to keep the total light time at about 16 hours a day, promote egg maturation and improve the laying rate.

Fifth, keep hot and warm drinks. The energy consumption of ducks is relatively large in winter, so hot water should be used for mixing and feeding while it is warm (about 38 ℃). Drinking water should be provided with warm water, and do not drink frozen water for ducks.

Sixth, play in the water normally. Release the duck late in the morning and close the duck early in the evening to reduce the number of times and shorten the time of launching. The weather is bad, when the temperature is below minus 5 ℃, the ducks do not shout strongly and can not swim in the water.

7. Increase the density appropriately. The feeding density per unit area can be increased, and 8-9 ducks can be raised per square meter to keep each other warm and keep a high temperature.

Eighth, feed night food at the right time. In winter, the days are short and the nights are long, so one warm feed can be added at night, which is beneficial to the duck against the cold and can increase the laying rate by more than 10%. Night feeding should pay attention to two points: one is to provide warm drinking water; the other is to feed mainly corn and other energy feed, supplemented by protein feed.

9. Do immune disinfection on a regular basis. All kinds of vaccination such as bird flu and duck plague should be done before winter. Duck houses should be cleaned and disinfected regularly and dewormed regularly. Once sick ducks are found, they should be isolated and treated in time, and the duck house should be disinfected urgently.
