Matters needing attention in increasing laying rate of Duck in Winter

First, pay attention to cold protection and warmth. The cold air is active frequently in winter, which makes it difficult for laying ducks to adapt and lead to the decrease of laying rate. Therefore, it is necessary to do a good job in cold protection and warmth of egg ducks, such as closing the doors and windows of the duck house to prevent the cold wind from attacking; laying mat grass so that the duck will not catch cold in its abdomen; replenishing light to promote the secretion of gonadal hormones in the duck's brain and promote follicular maturation and ovulation; appropriately increase the feeding density per unit area and use its body heat to increase the temperature of the duck house, so that the temperature of the duck house can be kept above 5 ℃ day and night.

Second, improve the feed standard. Feed should meet all kinds of nutritional needs of laying ducks, especially the content of energy and protein. The external temperature is low in winter, and the need for energy maintenance of laying ducks is much higher than that of other seasons. therefore, attention should be paid to increasing the content of energy and protein in the diet of laying ducks, so as to promote the continuous high yield of laying ducks.

Third, supplement green fodder. Green feed is rich in protein, vitamins and chlorophyll, especially some special nutritional factors, which can activate the reproductive function of laying ducks. Feeding an appropriate amount of green feed to laying ducks every day can not only improve the laying rate, but also improve the utilization rate of feed.

Fourth, timely stocking. Laying ducks should be released late and close early because of the cold winter. When there is severe frost and freezing weather, the laying duck can not be released until the sun comes out to disperse the frost and fog. Because the egg duck inhales the frost fog, it is easy to get sick, and the duck web stepping on the frost will make the duck web wrinkle and bleed. Therefore, it is necessary to master the weather, time and frequency of laying duck stocking.

Fifth, pay attention to the hygiene of the duck house. Improving the environmental hygiene of duck houses is the basis to ensure the health of ducks and improve the laying rate. Therefore, it is required that the mat grass in the duck house should be changed frequently, the equipment should be disinfected frequently, and the problems should be isolated and treated in time.
