For the purpose of effective therapy and prevention of post weaning E. coli diarrhea, Enrofloxacin-(Baytril premix) was administered in the feed and a series of investigations were made the occurence of diarrhea, weight gain, feed conversion rate, changes In the counts of faecal E. coli and susceptibility of the isolated E. coli strains to antimicrobials. The results obtained were as follows 1. The weaned piglets which were treated with Baytril premix gained the average body weight of 3.2kg over the control group at the age of 62 days. The result indicates a marked weight gain effect which, by statiscal analysis, showed a significant difference(P<0.01). Administration of Baytril premix also resulted in the improvement of feed conversion rate and provention of post weaning diarrhea. 2. The counts of faecal E. coli in Baytri premx treated piglets showed a marked decrease from 3.14${\times}$10$^<$TEX>8/cells/g to 2${\times}$10$^<$TEX>7/cells/g at 5days post treatment and 1${\times}$10$^<$TEX>5/cells/g at 10 days post treatment. 3. 10 strains of E. coli isolated fred the experimental pig farm were highly susceptible to Bayoil, gentamicin and trimethoprim plus sulfamethoxazole.
