The most commonly used antibiotics in the prevention and treatment of duck disease are sulfonamide and antibiotics. Here are some of the details:
The sulfonamide, sulfa (sulfadiazine)-(SN) is a white or yellowish crystal or powder, insoluble in water, used for infectious trauma. Sulfathiazole-(ST) sulfathiazole is a kind of white or yellowish powder, tasteless, insoluble in water and soluble in alkaline solution. It is absorbed in the intestine and excreted by the kidneys.
The drug is used for streptococcal and staphylococcal infections. The first application should increase the dose (double dose) after every 4 hours to feed once, after the disappearance of symptoms, but also to maintain the amount of half to continue to feed 1 to 2 days, in order to cure thoroughly. Each duck should take 0.2 g to 0.5 g daily with the same amount of Sodium bicarbonate. Sulfadiazine-(SD) sulfadiazine is a white or light yellow powder, odorless, insoluble in water, soluble in alkaline solution, less toxic, absorbed by the body slow, fast excretion.
The action and dose were the same as sulfathiazole. Sulfadimidine (sulfadiazine, sulfadiazine)-(SG) sulfadimidine white powder crystal, taste bitter, insoluble in water. Its effect is weaker than sulfathiazole, only part of it is absorbed after oral administration, but most of it remains in the intestine.
Therefore, the drug is mainly used for bacterial and coccidial enteritis. It can be fed in 0.5% ~ 0.6% of the feed. Sulfadimidine-(SM1) and sulfadimethylpyrimidine-(SM2) are similar to sulfadiazine, but they are absorbed quickly and excreted slowly. It can treat paratyphoid fever, fowl cholera and other diseases.
The dosage is 0.025% ~ 0.05% of drinking water. Sulfamethoxazole-(SPP) sulfamethoxazole is a middle-effect sulfamethoxazole with weak antibacterial activity. Advantage is easy to be absorbed, side effects are small. Take it every 12 hours. Note: The sulfonamide should not be used in laying ducks and breeding ducks to avoid lowering the egg production rate.
There are many kinds of antibiotics, penicillin penicillin, commonly used is penicillin G, the main clinical use of sodium salt or potassium salt. The drug has a powerful antibacterial effect on Gram-positive bacteria.
Intramuscular injection of 20,000-40,000 units for each duck, 10 million-5,000 units for each chick and 5,000-10,000 units for each medium chick. Coccidiosis can be controlled by mixing feed. Streptomycin is commonly used in its sulfate, hydrochloride. The drug is effective against Mycobacterium tuberculosis and most Gram-negative. It is also effective against some Gram-positive bacteria such as erysipelas and is less effective against other positive bacteria than penicillin. The effective concentration in the body can generally maintain 12 hours, excretion rate than penicillin slower.
Intramuscular injection 50 mg ~ 100 mg for adult duck and 10 mg ~ 40 mg for young duck. 0.01% ~ 0.02% of drinking water can be used. Tetracycline oxytetracycline, chlortetracycline and tetracycline are all tetracycline broad-spectrum antibiotic. The oral dose was 50-100 mg/kg BW for the first time and halved for the second time. 0.02% can also be fed into the feed.
Chloramphenicol is a broad-spectrum antibiotic antibiotic with similar inhibitory range to tetracycline group, but stronger effect on Gram-positive bacteria than chloramphenicol and oxytetracycline. Oral dose: 10mg ~ 20mg per duck per day, or 2.5 g in 5 kg of feed, or 0.1% ~ 0.2% in drinking water.
