For more than 50 years, it has been recognized that livestock performance can be improved if antibiotics are included in the diets at sub-therapeutic levels. As a result, a relatively large number of feed antibiotics have been approved for livestock feeding, and it is common praxis all over the world to include one or more antibiotics in the diets for production animals. Typically, daily gain and feed utilization are improved by 5 to 10% by the inclusion of these antibiotic growth promoters.
