Raise livestock and poultry to cool down in summer
Lowering the temperature of raising livestock and poultry in the summer is a safe and effective way to increase the growth rate and production performance of livestock and poultry, without increasing efficiency. 1. Maximize ventilation. Increase the natural ventilation of the building construction structure, install fan positive pressure ventilation, install exhaust fan negative pressure ventilation. Second, use evaporative cooling. Spray or spray water on the roof of livestock and poultry houses, and spray finely in the pens, pay attention to the use of deep well water with lower water temperature as much as possible to reduce the temperature. Third, reduce the breeding density. Minimize the rearing density and increase the number of drinking water and drinking water. Fourth, adjust the feeding time. Reasonably adjust the feeding time, feed in the morning in advance, add night feeds in the evening, feed in the cool will help increase weight. Fifth, vitamin supplements. Add 150 to 300 grams of vitamin C and other anti-heat stress drugs per ton in feed or drinking water. Sixth, improve feed nutrient concentration. Appropriately increase the feed nutrient concentration so that the livestock and poultry can also meet the corresponding nutritional requirements when they consume a limited amount of feed.
