Two dose levels of avoparcin in feed (10 ppm and 20 ppm) were tested for the growth promoting effects in growing pigs in comparison to 44.4 ppm tylosin. The average feed conversion rates seem to indicate that 10 ppm avoparcin is more effective than 20 ppm avoparcin and 44.4 ppm tylosin. But tylosin seem to be more effective than both avoparcin treated groups in consideration of the average daily weight gain.
