In order to select the best curative medicine on Piglets yellow dysentery, the efficacy of four drugs, Ceftiofur, enrofloxacin, gentamicin, ofloxacin, were compared in this test. Eighty unweaned piglets, which were on the verge of death and had all the classic symptoms of Piglets yellow dysentery, were chosen and divided randomly into four groups, 20 piglets each group. The first group was treated with Ceftiofur, it was prescribed as subcutaneous injection at a dose of 0.15 ml/kg(wt) for three days. The second group was treated with enrofloxacin, it also was prescribed as subcutaneous injection at a dose of 0.15 ml/kg(wt) for three days. The third group was treated with gentamicin, it also was prescribed as subcutaneous injection at a dose of 0.15 ml/kg(wt) for three days. The fourth group was treated with ofloxacin, it also was prescribed as subcutaneous injection at a dose of 0.15 ml/kg(wt) for three days. The results indicated that the recovery rate was 90% in group one, 50% in group two and 15% in group three and 20% in group four, and the best curative medicine on Piglets yellow dysentery is Ceftiofur, enrofloxacin is second drug, gentamicin and ofloxacin are the worst.
