(1) The uses of potassium permanganate solution are as follows: ① Disinfection of feeding utensils: 0.05% potassium permanganate solution can be used for soaking and disinfection of feeding utensils such as drinking fountains and food troughs, as well as for soaking and disinfection of green feed and eggs.

(2) Prevention of infection: 0.05% ~ 0.2% potassium permanganate solution is used to wash the stab wounds, ulcers and wounds on the duck body surface, which can promote the healing; Drinking 0.0 1% ~ 0.02% potassium permanganate water before and after blood collection can diminish inflammation and stop bleeding.

③ Disease prevention: 0.0 1% ~ 0.02% potassium permanganate solution was given to ducklings for 3 days to prevent diarrhea; Drinking dirty water twice a day in rainy season can prevent gastroenteritis; Usually ducks drink 1 ~ 2 times a week, which has anti-inflammatory and digestive functions. When meat ducks are deficient in manganese, drinking 0.0 1% ~ 0.02% potassium permanganate twice a day can alleviate the disease. (2) Problems that should be paid attention to when using potassium permanganate ① Weighing should be accurate to prevent the solution concentration from being too large or too small. Too small a concentration is not effective, and too large a concentration is easy to cause harm to the body.

(2) Prepare the liquid medicine with clear water, not dirty water or sewage, nor hot water, so as not to reduce the sterilization effect.

(3) Take the initiative now, not for a long time. Clean the medical devices in time after spraying, otherwise the medical devices may be damaged.
