In the specialized household raising cattle and raising chickens, we found that some people lacked the knowledge of the conversion of the dose of livestock and poultry, and often used the wrong dose to calculate the dose. It was not a small dose to cure the disease, or it was poisoning caused by excessive doses, which was not worth the candle. For this purpose, the conversion method of livestock and poultry medicine units is now described: General solid and semi-solid pharmaceutical dosage units: kilograms (kg), grams, milligrams (1 gram = 1000 milligrams = 10,000 micrograms, 1 kilogram = 1000 grams , 1 Jin = 500 grams, 1 two = 50 grams). Liquid dosage forms are expressed in terms of volume in milliliters and liters (1 litre = 1000 ml). Some antibiotics, hormones, vitamins and antitoxins (anti-virus serum) are expressed in close-up "Units" (U) or "International Units" (IU). 1 international unit of penicillin is equivalent to 0.6 micrograms of pure crystalline penicillin G sodium salt; 1 international unit of vitamin A is equivalent to 0.6 micrograms of beta-carotene or equivalent to 0.3 microgram of retinol, 0.344 microgram of vitamin A acetate, 0.55 microgram of vitamin A palmitic acid Fat; 1 international unit of vitamin E is equivalent to 1 mg of vitamin E acetate. It should be noted that PPm is often used to indicate the concentration of a drug contained in a feed or water when a group feeding method such as mixing or drinking is used. For example: 1PPm means 1kg (1000000mg) of feed or 1 liter of water containing 1g of medicine. One millionth. Then, if formulating 30 ppm olaquindox, the method is to add 30 grams of olaquindox to 1 ton of feed, 3 grams of olaquindox to 100 kg of feed, or 30 milligrams to 1 kg of feed, ie 30 parts per million. PPm and percentage (%) can be converted to each other, such as the conversion of% to PPm, the decimal point to the right by four, for example: 0.1% = 1000PPm; If you convert PPm%, the decimal point to the left by four, for example: 500PPm =0.05%. In addition, the instructions should be read before use to understand the conversion of drug content. When poultry is administered, doses are commonly used: doses per dose (expressing the amount of one dose per dose) and doses per kilogram of body weight (representing the dose per kilogram of body weight). For example, the intramuscular dose of kanamycin is 10-15 mg/kg body weight, and the intramuscular dose of 2 kg chicken is 20-30 mg. It is also necessary to understand the percentage of chemical preparations, such as: 10% sulfadiazine sodium injection refers to 100 milliliters containing 10 grams of sodium sulfadiazine.
