Influence of conditioning temperature on the coefficient of apparent ileal digestibility (CAID)¹ of DM, nitrogen (N), starch, fat, calcium (Ca), phosphorous (P), and AME (kcal/kg DM)² and total tract retention (TTR; %)² of DM in broiler starters (Exp. 1).

^a-cMeans in a column not sharing a common letter are significantly different (P < 0.05).

¹Each value represents the mean of 6 replicates (8 birds per replicate), measured on day 21.
