A farmer in Sichuan died of a large area of chickens due to irregular power failure. What are the effects of high temperature on farmers?

First of all, high humidity will increase the accumulation of harmful gases in the henhouse and endanger the health of chickens. In a sheep shed with too much humidity, it is often found that the smell is particularly unpleasant. This is because under humid environmental conditions, bacteria decompose sheep manure and feed, producing a large number of harmful gases such as ammonia and hydrogen sulfide, which penetrate into the sheephouse with the air, while harmful gases such as ammonia in water vapor are easy to escape. In addition, under the condition of high humidity, the continuous decomposition of harmful gases in the sheephouse will lead to the continuous increase of the concentration of harmful gases in the sheephouse, thus reducing the oxygen content in the air.

Secondly, the influence of ducks and geese on feed intake. Generally speaking, the isotemperate zone of meat ducks and geese is 10% ~ 27%, and that of ducks and geese is 13% ~ 25%. When the ambient temperature exceeds the upper limit of isothermal zone, the body will produce various nonspecific reactions, which are called thermal stress. In this process, the body limits the generation of heat through various metabolic pathways, increases the emission of heat, and achieves the purpose of keeping the body temperature constant. Eventually, it leads to changes in its physiological function, metabolism and immune mechanism, which seriously affects its growth and production performance.

And the mortality rate of pigs is high in summer. The threat of bacteria and the occurrence of diseases show some characteristics different from other seasons. Therefore, medical care must be changed accordingly. Heat stress is one of the most troublesome problems in raising pigs in summer. Effectively reducing the environmental temperature is the most effective control measure, but in actual production, pigs are still affected to varying degrees. Farmers' preparation in summer must be different from other seasons, including psychological preparation. Some farmers mentioned that the difficulty of raising pigs in summer is unimaginable.

You should know how to clean up the hot and humid weather, replenish fresh feed, spray water to cool down, don't add too much feed at a time, keep the feed fresh and prevent mildew. Buckets should be emptied once a day, not piled up. At noon, green vegetables or watermelon peel can be added appropriately to relieve heat stress. Feeding time should be adjusted in the evening or early morning. When the weather is hot, we should reduce or not reduce the feeding, drive the ducks appropriately and increase the feed intake. Additional sodium and potassium or carbonate supplements should be added to diet or drinking water to help maintain electrolyte balance.
