In summer, is it a big problem if pigs get bitten by mosquitoes and insects?

In spring, summer and autumn, whenever the moldy rainy season arrives, mosquitoes become unusually active. Mosquitoes like heat and fear cold; they begin biting people at 16-17°C, and 23-29°C is their suitable survival temperature. Mosquitoes like darkness and fear light, and are accustomed to being active in dimly lit environments. Mosquitoes very much like places with water, so undoubtedly farms have become the busiest places for mosquitoes. The harm of mosquitoes and insects to humans and livestock is mainly harassment, biting and stinging, and the spread of diseases, and they also have an extremely great impact on livestock sleep, etc. When infected, it follows an acute course; livestock become emaciated, suffer malnutrition, their body temperature rises, their movements become slow, and later they develop severe anemia and die from exhaustion. Chronically affected livestock show indigestion and stunted growth, and often become dwarf cattle. Sick cattle have poor appetite, diarrhea, and feces containing mucus, blood, and even blocky mucosa, with a fishy stench and tenesmus, and may even develop rectal prolapse, liver cirrhosis, ascites, sunken flanks between the shoulder blades, stiff forelimbs, hoarse vocalization and difficulty breathing, and can cause severe neurological disturbances, especially tenderness in the nasal area, forced movement, epilepsy, visual disturbances and acute encephalitis, sometimes dying suddenly. Diseases that may be transmitted by mosquito bites --- swine streptococcus --- sheep streptococcus ---- livestock diarrhea ---- avian influenza ---- pathogenic microorganisms ---- various epidemic infectious pathogens, introducing other sources of disease, etc. The breeding of diseases will increase the growth cycle of livestock (ranging from 5 to 20 days), cause a decline in the market selling price of livestock, and increase costs for farmers (medical expenses for sick livestock, manpower and material resources, and feeding costs due to delayed market release of livestock).
