Frequent cold air to reduce duck egg production in winter how to improve duck egg laying rate

Egg duck

First, pay attention to cold protection and warmth. The frequent cold air in winter makes it difficult for laying ducks to adapt, resulting in a decrease in egg production. Therefore, it is necessary to do a good job in protecting egg ducks from cold and warmth, such as closing the doors and windows of the duck house to prevent the invasion of cold wind; laying mat grass so that when the duck perches, the abdomen will not catch cold; supplement light to promote the secretion of gonadal hormones in the duck's pituitary gland, promote follicular maturation and ovulation; appropriately increase the feeding density per unit area, and make use of the body heat of the laying duck to increase the temperature of the duck house, so that the temperature of the duck house is above 5 ℃ day and night.

Second, improve the feed standard. The feed should meet all kinds of nutritional needs of laying ducks, especially the content of energy and protein. With the low external temperature in winter, the need for laying ducks to maintain energy is higher than that in other seasons. therefore, it is necessary to increase 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 proper amount of egg duck green feed every day can not only improve the laying rate, but also improve the feed utilization rate.

Fourth, timely stocking. Laying ducks should be released late and close early because of the cold winter. When there is severe frost and freezing, you have to wait for the sun to come out and the frost and fog to shine before you can release the egg duck. Because the egg duck inhales the frost fog is easy to get sick, and the duck web steps 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. To improve the hygiene of duck house is the basis to ensure the health of laying ducks and improve egg production. Therefore, the duck shed mat grass is often changed, with regular disinfection, found problems, timely isolation, treatment.
