Autumn temperature dropped egg duck to be nursed back to health
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.
First, to improve the protein of the feed Yongping animals have the ability to accumulate energy and ensure safe winter, autumn and winter are no exception. At this time, the energy level of the diet should be properly reduced or appropriate exercise should be maintained. The weight of the ducklings should be controlled at 1.5-2 kg and the protein level of the diet should be properly increased. The crude protein content in the diets 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 materials, it is better to set mineral feed bowls (1 bone meal plus 3 shell powders) in the duck house, allowing them to freely feed.
Second, do a good job of cold work in autumn fall faster, sudden cooling often lead to a significant decline in the ducks egg production rate, production should be minimized changes in the duck house microclimate, it is best to keep the duck house temperature at 13 °C ~ 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.
Third, do a good job of disease prevention in the fall is the high incidence of duck plague, duck cholera, egg drop syndrome and other diseases, to strengthen disease prevention and control work, keep the duck house clean, timely removal of feces, wash sinks, troughs, regular The duck houses and utensils are disinfected and vaccinated in strict accordance with immunization procedures to prevent diseases and ensure the health of ducks and ducks.
