In both trials, the antibacterial preparations increased rate of gain. In trial I, there were no differences in performance of pigs fed ASP-250, Mecadox, or TNA-290. In the second trial, pigs fed Mecadox gained faster than pigs fed ASP-250, Furox or Neo-Terramycin. Pigs fed diets supplemented with the various antibacterial preparations utilized feed more efficiently than those fed the nonmedicated basal diet.SwineAntibacterial preparationsRate of gainEfficiency of gainConference paper
