Two studies were conducted to determine the effects of eliminating the supplemental vitamin and minerals during the last 30 d of finishing on pig performance. The first study was conducted in a controlled university environment and the second under field conditions. Deletion of vitamin and mineral supplements for the last 30 d of finishing had no effects on pig performance or general health of pigs in either the university or the field trial. Besides lowering feed costs, deletion of dietary supplements may reduce the environmental impact of late finishing diets.
