Fumigation and disinfection of breeding eggs

Fumigation concentration standard: theoretically 2.83 cubic meters of formalin and 20 grams of potassium permanganate are added to the volume, which is a standard concentration (1x). In production, 14ml formalin and 7g potassium permanganate were added to 1 cubic meter as a standard concentration (1x). Fumigation dose and time just laid eggs need 3X concentration, fumigation 20 minutes; incubator 2X concentration, fumigation 20 minutes; in short, the higher the concentration, the shorter the time, the better the effect. Fumigation conditions: high temperature and high humidity, general temperature more than 25 degrees, humidity 70% to 80% the strongest germicidal force, the most thorough disinfection.
