a,b Means with different superscripts in the same row were significantly different (p < 0.05) as the main effect. The regression was considered significant when p < 0.05. IBW, initial body weight; FBW, final body weight; ADWG, average daily weight gain; TWG, total body weight gain; ADFI, average daily feed intake; FCR, feed conversion ratio; PER, protein efficiency ratio; SGR, specific growth rate.
