The growth and production of pigs have a suitable temperature range, which exceeds a certain temperature range. Lighter production performance may be reduced, and severe cases may cause death. Therefore, it is particularly important to control the temperature of the pig house in the summer. Here are some measures to reduce the temperature in the house.
1.Strengthen ventilation: Remove weeds from the pig house, open all doors and windows and ventilation holes as much as possible, and use electric fans and exhaust fans to enhance air flow inside the house.

The stage of broiler rearing should be repelled once. If the insects are not repelled, the feeds eaten by chickens are converted into After nutrition, it is eaten by insects, the chickens do not eat, the chickens become bugs, feed is wasted, and the cost is increased.
