FIELD: veterinary science. SUBSTANCE: animals are perorally or by injections introduced with aurol (thyrosol-C) preparation as 1+ACU- aqueous solution at the dosage of 4-15 ml once or repeatedly. Calves are fed with aurol (thyrosol-C) per 10 ml daily for 5 d before and 5 d after regrouping (transfer from dispensary to collection group) or injected subcutaneously per 5 ml 14 and 7 d before regrouping. Pigs are fed with aurol (thyrosol-C) as 10 ml inwards once daily for 7 d before weaning and transfer to raising groups and for 7 d after forming the raising groups or injected subcutaneously per 4 ml, twice at 5-d-long interval, 10 d before weaning and at the day of transfer into raising groups before the onset of regrouping. Poultry at vaccination are fed with aurol (thyrosol-C) at 15 mg/kg body weight for 3 d. EFFECT: increased safety under conditions of technological stresses, higher body weight gains in farm animals. 5 cl, 4 tbl
