Effects of Antibiotic Growth Promoters in Simple or Complex Diets Fed to Weanling Pigs
The most complex diet in this experiment at Hans H. Stein Monogastric Nutrition Research Laboratory at the University of Illinois increased the feed intake by weaner pigs, which led to faster growth rate but reduced feed efficiency. The addition of an antibiotic growth promoter increased daily gain only in one phase and impaired feed efficiency overall in this study.
