^aExperimental 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).^bIn the same row, values with different small letter superscripts mean significant difference (P < 0.05). ^cOrthogonal contrast statement: [CON] vs. [HF, HF-MB, HF-HB]. ^dOrthogonal contrast statement: [HF] vs. [HF-MB, HF-HB]. ^eOrthogonal contrast statement: [HF-MB] vs. [HF-HB]. Colostrum was collected within 2 h of birth of the first piglet. SEM Standard error of mean. Milk was sampled on d 12 and d 18 of lactation
