Egg ducks need to be recuperated after laying eggs for half a year.

Autumn temperature gradually drops, the temperature difference between day and night is large, the sunshine time becomes shorter, the autumn duck hatched in the previous year has been physically tired after half a year of laying eggs, and if there is a little carelessness in management, it will stop production and molt. Egg ducks hatched in early spring also begin to lay eggs from late September to mid-October, especially free-range egg ducks. Due to the lack of food in the late autumn, nutrition is often insufficient and egg production is reduced. Therefore, nutrition regulation of laying ducks should be strengthened in autumn, environment stability should be maintained, molting should be delayed as much as possible to improve production level.

1. Improve the protein level of feed. All animals in autumn have the characteristic of accumulating energy to ensure safe winter, and laying ducks are no exception. At this time, it is necessary to reduce the dietary energy level or maintain proper exercise, control the weight of laying ducks at 1.5~2 kg, and at the same time increase the dietary protein level appropriately, increase the crude protein content of captive laying ducks to 18%, and supplement appropriate protein feed for free-breeding laying ducks, so that the protein intake can meet the needs of laying eggs. In addition, supplement inorganic salt feed properly, put mineral feed basin in duck house (bone meal 1 part plus shell powder 3 parts), let them eat freely.

Second, do a good job of cold work. In autumn, the temperature drops rapidly, and the sudden cooling often leads to the decrease of laying rate of ducks. In production, the temperature change of duck house should be reduced as much as possible, and the temperature of duck house should be kept at 13℃~20℃. Rainy autumn, sports field easy to ponding, duck house grass pad easy to damp moldy, to reduce the humidity in the house, prevent grass pad muddy. Shortening the illumination time in autumn is not conducive to the reproduction of laying ducks. Artificial illumination should be supplemented and the illumination intensity should be stabilized. Generally, every 20 square meters duck house is equipped with a 40 watt bulb, covered with a lampshade, the distance between the lamp and the lamp is equal, and the hanging height is 2 meters to keep the lamp pool clean. Turn on the lights at dawn, turn off the lights at sunrise, turn on the lights after sunset, and turn off the lights after 16 hours.

III. Disease prevention. Autumn is the high incidence period of duck plague, duck cholera, egg reduction syndrome and other diseases. It is necessary to strengthen disease prevention and control, keep duck houses clean and sanitary, remove feces in time, wash sinks and troughs frequently, disinfect duck houses and utensils regularly, vaccinate in strict accordance with immunization procedures, prevent diseases and ensure the health of laying ducks.
