Each value represents mean ± SE (n = 3). Differences between means were tested with Duncan’s multiple range test.
Different letters indicate significantly different (p<0.05) by Tukey’s test; Different superscripts in the same row indicate a significant difference (p < 0.05).
IBW, initial body weight; FBW, final body weight; SGR, specific growth rate; PBW, body weight gain; SR, survival rate; FCR, food conversion rate; PE, feed efficiency.
