This study was conducted to investigate the effects of lecithin, mono-glyceride and mono-diglyceride on apparent total tract and ileal nutrient digestibilities in nursery pigs. Twenty [(Landrace$\times$Yorkshire)$\times$ Duroc] barrows were surgically fitted with simple T-cannulas. Dietary treatments included 1) CON (basal diet: soy oil), 2) LO (lecithin 0.5%), 3) MO (mono-glyceride 0.5%), 4) MG (mono-glyceride 1.0%) and 5) MDG (mono-diglyceride 1.0%). In apparent total tract nutrient digestibility, dry matter (DM) and gross energy (GE) digestibilities of MDG treatments were higher than LO and MG treatments (p<0.05). In nitrogen (N) digestibility, LO treatment showed the lowest compared to others (p<0.05). The digestibility of crude fat was higher in MDG treatment than CON and LO treatments (p<0.05). In apparent ileal nutrient digestibility, DM digestibility was higher in MDG treatment than LO and MG treatments (p<0.05). GE digestibility was higher in MDG treatment than LO, MO and MG treatments (p<0.05). N digestibility of MDG treatment was greater than LO treatment (p<0.05). Also, the digestibility of crude fat was higher in MDG treatment than CON and LO treatments (p<0.05). In conclusion, mono-diglyceride can increase apparent total tract nutrient and apparent ileal nutrient digestibilities of DM, GE, N and crude fat.
