Feed additives have been used to promote growth and feed efficiency of growing-finishing pigs for over 30 years. Typically, greatest response is found during early stages of growth and less response during the finishing period under conditions of good management. Recently, sarsaponin, a naturally occurring plant steroid derived from the yucca plant, has become available as a feed additive under the commercial name, Micro-Aid. Claims for this product include increased performance of· pigs during the finishing period. The antibiotic, Bacitracin MD, also has been shown to improve performance during later stages of growth more than is expected of most feed additives.
The study reported herein was designed to evaluate the response of pigs to these two feed additives when fed separately or in combination.
