^a Multiple samples of each diet were collected, blended and subsampled, and analyzed (Missouri Agricultural Experimentation Lab, Colombia, MO; Ward Laboratories, Kearney, NE; and Midwest Labs, Omaha, NE). All values represent the combined average of the chemical analyses of diets for the experiment.

^b Tri-basic copper chloride, (IntelliBond C, Micronutrients USA).

^c Copper-methionine hydroxy analogue (Mintrex Cu, Novus International).
