Means with dis-similar superscripts (a, b, c, d) in the same column significantly differ at p < 0.05. SEM: standard error of means. n: number of observations in the treatment group. 1 Traits: IBW, initial body weight 22 d of age; FBW, final body weight at 42 d of age; BWG, body weight gain; FI, feed intake; and FCR, feed conversion ratio.
