Rearing techniques of Egg Duck in Autumn

The temperature drops gradually in autumn, the temperature difference between day and night is large, and the sunshine time becomes shorter. The autumn ducks hatched last year are already physically tired after laying eggs for more than half a year. If there is a slight carelessness in management, they will stop production and change their hair. Egg ducks hatched in early spring also begin to lay eggs from late September to mid-October, especially free-range laying ducks, because there is not much food to be found in late autumn, which often results in insufficient nutrition and reduced egg production. Therefore, attention should be paid to strengthen the nutritional regulation of laying ducks in autumn, keep the environment stable and postpone molting as far as possible so as to improve the production level.

The first is to improve the protein level of feed. In autumn, animals have the characteristics of accumulating energy and ensuring safe winter, and laying ducks are no exception. At this time, the energy level of the diet should be appropriately reduced or proper exercise should be maintained, the body weight of the laying duck should be controlled at 1.5-2kg, and the dietary protein level should be appropriately increased, and the crude protein content in the diet of captive laying ducks should be increased to 18%. The free-range laying ducks should be properly supplemented with protein feed so that they can ingest enough protein to meet the needs of egg production. In addition, in order to properly supplement inorganic salt feed, it is best to set up a mineral feed basin (1 part of bone meal and 3 parts of shell powder) in the duck house and allow it to eat freely.

The second is to do a good job of cold prevention. The temperature drops rapidly in autumn, and the sudden drop in temperature often leads to a great decrease in the laying rate of ducks. In production, the microclimate change of duck house should be reduced as much as possible, and it is best to keep the temperature of duck house at 13 ℃ ~ 20 ℃. Autumn is a rainy season, the sports ground is easy to accumulate water, and the mat grass in the duck house is easy to be damp and moldy, so measures should be taken to reduce the humidity in the house and prevent the mat grass from getting muddy. The natural light time in autumn is gradually shortened, which is not conducive to laying ducks to maintain exuberant reproductive function, so it is necessary to supplement artificial light and stabilize light intensity. Generally every 20 square meters of duck house is equipped with a 40-watt light bulb, the lamp is covered with a lampshade, and the distance between the lamp and the lamp is equal, and the suspension height is 2 meters to keep the lamp pool clean. Can turn on the light at dawn in the morning, turn off the light at sunrise, turn on the light after sunset in the evening, and turn off the light after 16 hours.

The third is to do a good job in disease prevention. Autumn is a period of high incidence of diseases such as duck plague, duck cholera and egg drop syndrome. We should strengthen disease prevention and control, keep duck houses clean and hygienic, remove feces at the same time, wash sinks and food troughs, and disinfect duck houses and utensils regularly. Vaccination should be carried out in strict accordance with the immunization procedure to prevent the occurrence of diseases and ensure the health of laying ducks.
