Eighty weaning pigs at the age of 4 weeks, average weight 7.0 kg, were allotted into 4 groups of 20 each in hygienic battery house. Apart from the standard basal ration, 30 ppm. TIAMULIN was added to feed for group 1 and 2 with 150 ppm. Oxytetracycline for group 1 and 50 ppm. Trimethoprim plus Sulfadiazine for group 2. Animals in group 3 received 110 ppm. of Tylosin plus 110 ppm of Sulfamethazine. Animals in group 4 served as no medication control. After 8 consecutive weeks no clinical sign of the common diseases were observed in all weaning pigs. All animals with medicated feed developed a better growth performance than control ones as indicated by value of relative difference of ADG of 109.7, 108.9 and 100.4 and value of relative difference of FCR of 89.2, 93.5 and 97.8, for group 1, 2 and 3, respectively. Turn over rate were 3.33, 1.89 and 0.48 times of the investment cost for feed additives in group 1, 2 and 3, respectively.
