The values are means, n = 18 replicate pens for each dietary treatment with each pen containing 5 chicks. *Values differ from the corresponding control value for a given parameter (*P < 0.05, **P < 0.01, ***P < 0.001).

BWG = body weight gain, AGP = alpha 1 acid glycoprotein, AZ = AZOMITE, and ND = not determined.
