Fifteen flocks of replacement pullets affected with hysteria were treated with metoserpate hydrochloride via the drinking water after water was withheld for an adequate period. The dose was 4 mg/kg body weight (BW) on day 1, and 2 mg/kg BW on days 5 and 9. Metoserpate hydrochloride proved effective and safe for treating clinical cases of hysteria in replacement pullets.
Tiamulin was compared, under a variety of experimental conditions, with 4 water-soluble antibiotic preparations available commercially for the control and treatment of mycoplasmal infections in poultry. In chickens, tiamulin was more effective than the reference antibiotics in preventing and eradicating airsacculitis caused by Mycoplasma gallisepticum and preventing airsacculitis and synovitis caused by M. synoviae. In turkeys, tiamulin and tylosin were equally active in preventing airsacculitis caused by M. gallisepticum. Tiamulin was highly effective in preventing airsacculitis also when administered as a single subcutaneous dose.
