If small-scale pig farmers find that their pigs are sick, they can use certain bloodletting methods to treat them. It should be noted that the instruments used for bloodletting and the pig’s bloodletting site must be disinfected in advance. Parts suitable for bleeding include: ear tip, pig dorsal ear vein, 5-10 cm from the ear tip; tail tip, about 5 cm from the pig tail tip; oral cavity, the midpoint of the third edge on both sides of the midline of the pig's mouth. When pigs have a cold, fever, or depression, bleed the sharp tips and tails of pigs. 10 ml of blood for large pigs and 5 ml of blood for piglets will have an antipyretic effect. In addition, copper sulfate, ferrous sulfate, penicillin, neomycin, erythromycin, etc. can be used for treatment, and feeding and management should be strengthened to maintain heat and moisture to promote the healthy growth of pigs. Some diseases can be treated with medications. For example: pig respiratory diseases, pig digestive tract diseases, pig kidney diseases, etc. can all be treated with drugs. When pigs are sick, each pig can be treated with 0.1% sulfa drugs (or antibiotics), or intramuscular injection of penicillin as directed by the doctor. 1% sulfa drugs (or antibiotics) or 0.1% tetracycline or chloramphenicol eye drops can also be used. and 1% nitrofurantoin eye drops.

When pigs become sick, they must be treated promptly, generally within 3 days of onset. If a sick pig is found dead, the carcass must be fully disinfected, then soaked in 10% potassium permanganate solution for 30 minutes, then taken out, rinsed and dried, then rinsed with 5% potassium permanganate solution, and Applying 1% to 2% copper sulfate solution on a disinfected wooden board and leaving it for more than 15 days can inhibit and kill pathogenic bacteria such as Escherichia coli, Shigella dysentery and Salmonella. ?

In terms of prevention, make a reasonable and scientific layout of the breeding site, and use underground breeding facilities to reduce the sharp increase in temperature inside the house and increase the temperature inside the house; the pig house must be installed High-efficiency and energy-saving power-saving devices can only be used when the daily power consumption of each pig is less than 300 kWh, saving energy consumption; the pig house should be designed as far away from pollution sources as possible, with good ventilation, and the temperature and humidity of the pig house should be maintained Within the range suitable for pig growth.
