Rats and fish can use oxytetracycline. Oxytetracycline has bacteriostatic effect. If the concentration is high, it also has bactericidal effect. Oxytetracycline has a wide range of treatment, mild properties and low toxicity, which is suitable for the prevention and treatment of bacterial diseases in rats and fish. The amount of oxytetracycline used depends on the cause and symptoms of the fish and the size of the fish. Oxytetracycline can be taken orally or in a medicated bath. For oral administration, oxytetracycline can be crushed and dissolved in a small amount of water, then the feed is soaked in water, the water is absorbed and dried in the sun, and then the diseased fish can be fed. During the medicated bath, oxytetracycline can be dissolved in water in equal proportion, and then the diseased fish is put into the medicated bath.
in the treatment of rat and fish diseases is relatively large, such as enteritis, saprolegniasis, scaly disease, gill rot disease, congestive disease and trauma of rat and fish can be treated. Usually, a small amount of oxytetracycline can be added to the water in which fish are raised, which can inhibit the growth of bacteria. Although oxytetracycline is mild, it should not be used excessively, because excessive use can cause damage to the liver or kidney function of fish. When using oxytetracycline, it can be fed to sick fish with probiotics, which can reduce the harm of oxytetracycline to fish.
