Adjust diet formulas. Appropriately reduce the energy level, increase the protein, calcium and phosphorus content accordingly, increase the vitamin content in the diet, especially the content of vitamin C and vitamin E.
Change the feeding method. Before 8 o'clock in the morning, the ducks were fed to strengthen the night feeding, and the ducks were given plenty of food to drive them to normal feed intake through proper driving and feeding.
Summer cooling. In the hot season, according to the actual production, the temperature in the greenhouse after duckling is usually 7°C~13°C higher than that in the greenhouse. Therefore, it is necessary to do a good job in preventing the heat and cooling: we can adopt measures such as reducing the breeding density, increasing the drinking fountains, strengthening ventilation, direct sunlight, and shading.
