Scientists are continually seeking ingredients to be added to common swine rations which will increase gain and feed efficiency. During recent years there has been some interest in copper as a growth promoting factor when fed at high levels. Several reports have indicated that copper is an effective growth stimulant when added to swine rations at a level of approximately 250 ppm. However, its widespread usage as a feed additive has been restricted by reports of toxicity at levels generally recommended for improving rate of gain and feed efficiency.
