Summary Apparent ileal digestibility ( AID ) of diets containing sesame expeller ( SE ) and soya bean meal ( SBM ) was determined using 15 piglets ( Genetiporc ® ), weaned at 17 ± 0.4 days with average body weight of 6.4 ± 0.7 kg (Fertilis 20 × G Performance, Genetiporc ® , PIC México, Querétaro, México). Piglets were randomly assigned to three treatments: (i) a reference diet with casein as the sole protein source; (ii) a mixed diet of casein– SE ; and (iii) a mixed diet of casein– SBM . The chemical composition of SE and SBM was determined, and AID and standardized ileal digestibility ( SID ) of crude protein ( CP ) and amino acids ( AA s) were determined for each protein source. SE contained greater quantities of ether extract, neutral detergent fibre, phytic acid, methionine and arginine than SBM . Lysine and proline contents and trypsin inhibitor activity were higher in SBM than in SE . The AID and SID of CP and AA (except for lysine and proline) were similar in SE and SBM . The AID of lysine and proline was higher in SBM than in SE (p < 0.05), and the SID of proline was higher in SE than in SBM (p < 0.05). These findings indicate that SE is an appropriate alternative protein source for early weaned pigs.
