¹Experimental diets were a corn-soybean meal based diet (CON), CON + 8% soybean oil (HF), HF + medium dose of branch chain amino acids (BCAAs, 0.11% leucine, 0.06% isoleucine and 0.22% valine; HF-MB), and HF + high dose of BCAAs (0.22% leucine, 0.12% isoleucine and 0.44% valine; HF-HB). Control diet contained no soybean oil (CON). In the same row, values with different small letter superscripts mean significant difference (P < 0.05) when comparing [CON] vs. [HF, HF-MB, HF-HB]. A trend is declared when P is no more than 0.10 (0.05 ≤ P ≤ 0.1). ²Litter size cross-fostering was conducted within treatment. ³Orthogonal contrast statement: [CON] vs. [HF, HF-MB, HF-HB]. ⁴Orthogonal contrast statement: [HF] vs. [HF-MB, HF-HB]. ⁵Orthogonal contrast statement: [HF-MB] vs. [HF-HB]. ADFI average daily feed intake, ADG average daily gain, BW body weight, SEM Standard error of mean, TFI Total feed intake, wt weight
^{a, b} Different letters represent statistically different by the effect of HF
