摘要
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 (AAs) 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.

使用15头仔猪（Genetiporc®）测定含有芝麻榨汁机（SE）和大豆粗粉（SBM）的日粮的表观回肠消化率（AID），在17±0断奶。4天，平均体重为6.4±0.7kg（Fertilis 20×G Performance，Genetiporc®，PICMéxico，Querétaro，México）。仔猪被随机分配到三个处理：（i）参考饮食与酪蛋白作为唯一的蛋白质来源; （ii）酪蛋白-SE的混合饮食;和（iii）酪蛋白-SBM的混合饮食。测定了SE和SBM的化学组成，并确定了每种蛋白质来源的粗蛋白质（CP）和氨基酸（AA）的AID和标准回肠消化率（SID）。SE比SBM含有更多的乙醚提取物，中性洗涤纤维，植酸，甲硫氨酸和精氨酸。SBM中赖氨酸和脯氨酸含量和胰蛋白酶抑制剂活性均高于SE。 SE和SBM中CP和AA的AID和SID（赖氨酸和脯氨酸除外）相似。SEM中赖氨酸和脯氨酸的AID高于SE（p 0.05），SE中脯氨酸的SID高于SBM（p 0.05）。这些发现表明，SE是早期断奶仔猪的一个合适的替代蛋白来源。
