90 swines both castrated and gilt, at the average weight of 14.3 kg. were divided into 9 pens; and were fed for 103 days by using the appropriate basal ration. Pens 1 - 3 were fed without any feed additive (Group A or T1). Only pens 4-6 were provided with 100 ppm. of furazolidone in the feed (Group B or T2); and only pens 7-9 were added with a preparation provided in the final dose of 50 ppm. carbodox and 30 ppm. mountel tartrate in feed (Group C or T3). Initial, interim and final weights of each animal and the amount of intake feed were also collected. Along the grower period, it was unable to distinguish any difference among feed consumed and FCR in each experimental group. The ADG of T2 and T3 were nearly equal and slightly better than T1 but it was not statistically significant. In the final period, the total feed consumed by both treated groups were markedly lower than untreated group; and the difference of feed consumed per pen between T3 and T1 was statistical significance. The difference in ADG between T2 and T3 and between T2 and T1 did not indicate any statistical significance; but T3 over T1 demonstrated a statistical difference. The FCR of T3 was significantly better than T1 while the differences between T1 and T2 or T2 and T3 were not. For the whole experimental period the results demonstrated no statistical difference of ADG among the 3 groups when compared between T3 and T1 the lower feed consumed and more efficiency of FCR of T3 were statistically significant
