In addition to the smell of smoke in the summer, the pig house is often accompanied by a large group of mosquito humming sounds. Due to the special environment and the excretion of pollutants in the pig house, this situation has created favorable conditions for the breeding of flies and their eggs. Therefore, the phenomenon of mosquitoes and flies swarming across the building in the farm is very serious. Mosquito bites not only spread the disease, but also affect the growth of pigs. Therefore, breeding mosquito killer lamps is indispensable.

In addition, we should decide whether to vaccinate pigs based on the specific circumstances of the herd. Strengthen immunization and not ignore vaccination due to high temperatures in summer. In recent years, a large number of pigs have died of hyperthermia syndrome. We really look at it and it hurts in our hearts. We have to do ”precaution is greater than treatment.” Therefore, vaccination also needs to be done.

In particular, attention should be paid to the vaccination of Japanese encephalitis vaccine in the summer. As a middle host of Japanese encephalitis, mosquitoes have a strong spread and extremely fast propagation speed. If a mosquito bite with a Japanese encephalitis virus bites, the boar will develop orchitis, the testicles will become larger and smaller, lowering the quality of the boar semen, directly affecting the production performance; if the gilt is infected with Japanese encephalitis, It can cause gilts to be estrus or not estrus; infection with sows can lead to miscarriage. These are caused by the lack of anti-epidemic and mosquito repellent work.

In a pig farm, four pregnant sows had been aborted due to infection with Japanese encephalitis. In just 5 days, the number of aborted sows increased to 7 and 11 dead pigs . The impact of small-scale pig farms may be devastating, and large-scale pig farms may be destroyed in this way, and many years of efforts have been lost.
