Two experiments were conducted to compare the effects of several growth promotants on the growing-finishing swine. In each of the both experiments a total of 120 cross-bred pigs weighing an average of about 14kg(Exp. I) or about 16kg(Exp. II) was divided into 12 pens of 10 pigs each. Each pen was assigned to one of the 3 dietary treatments with 4 replications (2 pens of males and 2 pens of females each). The 3 treatments were nomedicated control (T1), olaquindox at 50ppm during the starter period and 25ppm during the later periods (T2), and a combination of 50ppm carbadox and 30ppm morantel citrate fed during the starter and grower periods (Exp. I) or during only starter period (Exp. II), followed by 25ppm salinomycin (T3). The results obtained are summarized as follows: 1 . Medicated pigs gained generally more weight and consumed more feed than nomedicated pigs. Feed efficiency was also improved by supplementation of diets with growth promotants. 2. A combination of carbadox and morantel citrate followed by salinomycin performed slightly better than olaquindox. 3. The growth promoting effects of the antimicrobials, in general, were relatively greater during the early stage of the pig growth than during the later stage.
