Relative Proportions of the major fatty acids in sow colostrum. Sows were fed with control diet containing no soybean oil (CON), corn-soybean meal based diet containing 8% soybean oil (HF), HF supplemented with medium dose of BCAAs (HF-MB), respectively from late gestation to weaning. BCAAs increased the proportion of C18:1n9c (P = 0.030) and tended to decrease the proportion of C18:3n3 (P = 0.063). The significantly increased proportion of minor fatty acids included C15:0 (p < 0.001), C17:0 (P < 0.001), C20:1 (P = 0.045) and C20:3n6 (P = 0.011). T-test analysis displayed that compared to HF colostrum. HF contained lower percentage of C14:0 (P < 0.001) and the sum of C8:0, C10:0 and C12:0 (P < 0.01) compared to CON. *denotes difference at P < 0.05 between CON and high fat diet groups (HF and HF-MB), and # denotes difference at P < 0.05 between HF and HF-MB groups.
