The temperature dropped gradually in autumn, the temperature difference between day and night was great, and the sunshine time was shortened. The fall duck that hatched in the previous year had been fatigued after half a year's production of eggs, and the management was slightly careless, and it would stop the production of wool. Ducks that hatched in early spring also began to lay eggs from late September to mid-October, especially free-range ducks, because late autumn can not find much food, often causing nutritional deficiencies and decreased egg production. Therefore, in the fall, attention should be paid to strengthening the nutritional regulation of laying ducks, keeping the environment stable, and delaying their moulting as much as possible in order to increase the production level.
One is to increase the protein level of feed. Autumn animals have the property of accumulating energy and ensuring safe wintering. Ducks and ducks are no exception. At this time, the energy level of the diet should be properly reduced or appropriate exercise should be carried out. The weight of the ducklings should be controlled at 1.5 to 2 kg, and the protein level of the diet should be properly increased. The crude protein content in the diet of the captive ducks should be increased to At 18%, free-range protein ducks should be supplemented with protein feeds so that they can consume enough protein to meet the egg production needs. In addition, to properly supplement the inorganic salt feed, it is best to set mineral feed bowls (1 bone meal plus 3 shell powders) in the duck house, allowing them to freely feed.
The second is to do cold work. The fall of temperature in autumn is rapid. Sudden cooling often leads to a significant decline in the egg production rate of the duck population. Changes in the microclimate of the duck house should be reduced as much as possible. It is best to maintain the temperature of the duck house at 13°C to 20°C. Autumn is a rainy season. The playground is prone to water. The grass in the duck house is prone to dampness and mildew. Measures must be taken to reduce the humidity in the house and prevent the grass from becoming muddy. The natural light time in autumn is gradually shortening, which is not conducive to maintaining vigorous reproductive function of ducks and ducks. It is necessary to supplement the artificial light and stabilize the light intensity. A 40-watt light bulb is generally installed in a 20-square-meter duck house. The light bulb is covered with a lamp shade, and the distance between the light and the light is the same. The height of the suspension is 2 meters and the lamp pool is kept clean. In the morning, turn on the lights during the morning and turn off the lights during the sunrise. Turn on the lights after sunset and make up for the lights after 16 hours.
The third is to do a good job in disease prevention. Autumn is a high incidence of diseases such as duck gizzards, duck cholera, and egg drop syndrome. It is necessary to strengthen disease prevention and control and keep the duck houses clean and hygienic. Simultaneously, the manure should be removed, and the sinks and troughs should be washed frequently to regularly sterilize the duck houses and utensils. In strict accordance with the immunization program for vaccination, to prevent the occurrence of diseases to ensure the health of ducks and ducks.
