Summer is the prime time for raising meat ducks, but the high temperature and high humidity environment will make the duck house feces rot and ferment, breed pathogenic microorganisms, induce disease, and adversely affect the growth of ducklings. To improve the survival rate of ducklings in summer, we must do the following eight points: First, we must reduce the stocking density. Prevent crowding of ducks, stacking pressure, accumulating temperature, and adding water bowls. Second, we must adjust the feed formulation. The feed formula for ducks at different stages of growth differs from each other. The summer feed formula should meet the requirements of all essential amino acids to keep the protein levels as low as possible to reduce feed digestion heat. Third, we must change the feeding method. It is advisable to adopt net culture to reduce the contact between ducklings and feces, reduce the spread of disease, reduce the incidence, and also reduce the nutrient consumption and heat production of ducks. Fourth, we must optimize the feeding time. Try to feed in cool time during the morning and night 8-10 hours. Fifth, we must reduce sunlight exposure. Build a high and spacious duck house, where water can be sprayed or misted on the roof during high temperatures, and white ash can be brushed on top of the house. Sixth, supply fresh feed. If the feed is placed too long during high temperature and high humidity, or the feed in the feed tank is stagnant for too long, it will cause deterioration of the fermentation and should ensure the supply of fresh feed. Seventh, we must keep the environment quiet. During the hot period, sudden shocks and noises must be avoided to interfere with the duck population and the activity of ducks should be minimized. Eighth, we must engage in disinfection and disease prevention. Do a good job of disinfection to prevent flies and mosquitoes from breeding, so that the ducks will not be harassed by pests.
