This experiment was conducted to determine the Effect of soybean oil, dried palm oil powder and monoglyceride supplementation on growth performance and serum lipid changes in weaned pigs. One hundred twenty five cross-bred pigs((Y×L)×D, 6.00±0.79kg average initial BW) were used in a 21 d growth trial. Dietary treatments included SOY(containing 5% soybean oil), PALM(containing 5.5% dried palm oil powder) and SOPM0, 12.5 and 25(containing 2.5% soybean oil and 2.7% dried palm oil powder containing 0%, 12.5% and 25.0% monoglyceride, respectively). For the whole period, ADFI was increased in dried palm oil powder containing monoglyceride and PALM treatments compared with SOY and SOPM0 treatment(P<0.05). ADG and G/F were not affected by treatments. Digestibility of fat was higher(P<0.05) for pigs fed SOY diet than fed other diets. SOPM diets containing monoglyceride showed increased fat digestibility compared with PALM diet(P<0.05). SOPM12.5 and SOPM25 treatments were no difference with SOY treatment. However, there were no significant differences in digestibilities of DM, N and DE(P>0.05). Backfat thicknesses were not significantly different among treatments. Pigs fed SOY diet was decreased in serum total cholesterol, HDL-cholesterol, total lipid and was increased in free fatty acid than those fed other diet. Also, triglyceride concentration in serum was increased in PALM treatment compared with SOPM treatment(P=0.06). In conclusion, feeding soybean oil in weaned pigs showed higher fat digestibility and lower cholesterol and triglyceride concentration in serum than feeding only dried palm oil powder. Also, pigs fed monoglyceride were improved fat digestibility compared with those fed dried palm oil powder only.
