Abbreviations: BWG, mortality corrected BW gain; FCR, mortality-corrected feed conversion ratio; FI, mortality-corrected feed intake; SEM, largest pooled standard error of the pairwise mean comparisons.

¹All birds received a common corn and soybean-meal based diet provided in 3 phases: starter (day 1–13), grower (day 14–33), and finisher (day 34–41). Pen served as the experimental unit with 30 replicate pens (12 birds per pen) per treatment.
