First, adjust the feed formula to ensure the normal growth of duck needs.
1, the whole feed formula. Because feed intake decreases with increasing ambient temperature, it is difficult to ensure day-to-day nutritional intake of ducks with other seasonal recipes. Formulas for meat ducklings with different temperatures and different growth stages in summer should be formulated. The formula can use fat to replace some of the carbohydrates. On the premise of satisfying all essential amino acids, the protein level should be as low as possible to reduce the heat dissipation during feed digestion.
2, supply fresh feed. During high temperature and high humidity period, if the feed is left for a long time or the feed in the feed tank is left for a long time, it will cause the feed to deteriorate and even become seriously mildewed. In the summer, it should be ensured that the purchased feed is fresh and the best. It is used up in about 1 week.
3, add anti-heat stress drugs. Adding 50 to 200 ml of vitamin C per kilogram of feed during the summer will help reduce the adverse effects of heat stress on the duck's body and protect other nutrients from oxidation.
4, adjust the feeding time. Try to feed at 4 to 5 o'clock in the morning and 8 to 10 o'clock in the evening, and let the ducks rest during the day.
5, appropriate feeding some green feed to improve the duck's appetite.
Second, do a good job of environmental hygiene control to prevent ducks from heat stress.
1, reduce the impact of solar radiation on ducks. Building a high and spacious duck house is a more effective way to reduce the effects of solar radiation. During the high temperature period, water is sprayed on the inner roof or atomized by water spray. White ash can also be brushed on the outer roof, and greening of the surrounding environment can be done.
2, speed up the loss of duck body heat. The duck house should be open and ventilated all around. When the temperature is too high, ventilation should be used to strengthen the ventilation, to ensure air convection, and ventilation at night should be strengthened.
3, reduce the breeding density. Too much density means that there are too many ducks per square meter. Decreasing the number of ducks in the duck house can reduce the total heat production in the house. At the same time, we must pay attention to increase the number of sinks and troughs, generally controlling 6-8 feathers per square meter.
4. Keep the duck house dry. In the hot season, the ducks drink more than other seasons, so the water vapor that is lost through the respiratory evaporation is more than in other seasons. In particular, the evaporation of the excreted water and the excrement fermentation at high temperatures are the main reasons for the increase in humidity and the increase in the amount of harmful gases in the duck house.
Third, daily management to ensure the healthy growth of ducks.
1, strong observation of the duck group. Abnormalities were found in time to take countermeasures. Equipped with emergency treatment rooms to avoid losses.
2, change the feeding method. Net-culture can prevent its contact with feces, reduce the spread of the disease, and reduce the incidence. Net raising can reduce the movement of ducks, reduce the nutrient consumption and heat production of ducks, and is conducive to the healthy growth of ducks in summer. When using ground ducks, it is best not to use thick dunnage in the summer, in particular, do not use straws with poor hygroscopicity as litter, and later use cement or bricks to raise them, and increase the frequency of defecation.
3, keep the water sports stadium clean and clean. There are conditions to build a shack on the pool so that the water temperature can be kept low, and clean water every two days when the pool is shallow.
4, reduce the interference of ducks. Avoid disturbing ducks during hot periods to minimize duck activity.
5, make daily disinfection work. Prevents flies and mosquitoes from breeding, prevents ducks from being disturbed by pests and spreads the disease.
6, to strengthen the prevention and treatment of duck disease, do a good job of daily observation, analysis, diagnosis and treatment of ducks, to ensure the smooth implementation of feeding and management measures.
How to manage meat ducks in summer
Ducks are for economic benefit, and for summer ducks are both unfavorable for growth and control of unfavorable diseases. In the summer, good ducks need to be cultivated to adjust feed formulations, reduce density, change the environment, and strengthen management. The specific work is as follows:
