An experiment was conducted to determine effects of Zn-bacitracin in promoting growth and improving feed conversion of growing-finishing swine. A total of 120 crossbred pigs weighing an average of approximately 20 kg was divided into 12 pens of 10 pigs each. Each pen was assigned to one of the 3 dietary treatments (0, 20, and 100 ppm Zn-bacitracin) so that each treatment included two pens of males and ten pens of females. Pigs fed Zn-bacitracin gained significantly (P < 0.05) more weight than the nonmedicated control pigs. Feed conversion was significantly (P < 0.01) improved by feeding 100 ppm of Zn-bacitracin.
