^aAnalysis was performed by Ward Laboratories, Inc. (Kearney, NE) on pooled diet samples. All diets were formulated to contain 16.5 ppm Cu and 110 ppm of Zn from the trace mineral premix.

^bPhase 2 treatment diets were fed from d 5 to 26 (exp. 1) or to d 33 (exp. 2), whereas a phase 1 common was fed to all pigs from d 0 to 5 and a phase 3 common diet was fed to all pigs from d 26 (exp. 1) or 33 (exp. 2) to d 47.

^cIn exp. 2 only, pharmacologic Zn diet treatments had an addition of 3,000 ppm Zn from added ZnO from d 5 to 12 and an addition of 2,000 ppm Zn from added ZnO from d 12 to 33.
