Effects of adding fermented wheat to liquid diets on gastrointestinal characteristics in weanling piglets were studied. Gastrointestinal characteristics of 40 28-d-old weanling piglets were measured at the day of weaning (d 0) and at d 4 and 8 after weaning. Piglets were group-housed and fed twice daily. Feeding level was based on the average metabolic BW of piglets per group. Groups were fed a liquid diet with either 45% unfermented wheat (FERM_0) or 45% fermented wheat (FERM_45). The other 55% of the diet was identical. To ferment wheat, water at 30 degrees C was added to milled wheat in a 1:2.2 ratio. The pH and contents of lactic acid, acetic acid, propionic acid, and butyric acid were measured in the digesta of the stomach, three parts of the small intestine, cecum, and large intestine. In addition, changes in microbial populations in the digesta were studied during the period after weaning. Moreover, villus height, crypt depth, and villus shape were studied in the small intestine. Piglets fed FERM_45 showed lower gastric pH (P < 0.05) at d 4 and higher gastric lactic acid content (P < 0.001) at both d 4 and 8. Piglets fed FERM_45 showed in the first part of the small intestine higher villus height (P < 0.01) at d 8 and higher villus:crypt ratio (P < 0.001) at both d 4 and 8. Villus shape tended (P < 0.10) to be favorable for piglets fed FERM_45. The present study indicates that feeding a partly fermented liquid diet to weanling piglets may be a concept to prevent undesirable changes in mucosal architecture after weaning.
研究了在断奶仔猪的液体日粮中添加发酵小麦对其胃肠道特征的影响。在断奶日（第0天）以及断奶后第4天和第8天，对40头28日龄断奶仔猪的胃肠道特征进行了测定。仔猪群体饲养，每天饲喂两次。饲喂水平基于每组仔猪的平均代谢体重。各组分饲一种液体日粮，其中一种含有45%未发酵小麦（FERM_0），另一种含有45%发酵小麦（FERM_45）。日粮的其他55%相同。为了发酵小麦，将30℃的水以1:2.2的比例添加到磨碎的小麦中。测定了胃、小肠三段、盲肠和大肠食糜中的pH值以及乳酸、乙酸、丙酸和丁酸的含量。此外，还研究了断奶后期间食糜中微生物种群的变化。此外，还对小肠中的绒毛高度、隐窝深度和绒毛形状进行了研究。饲喂FERM_45的仔猪在第4天胃pH值较低（P<0.05），在第4天和第8天胃乳酸含量较高（P<0.001）。饲喂FERM_45的仔猪在第8天小肠第一段绒毛高度较高（P<0.01），在第4天和第8天绒毛与隐窝比值较高（P<0.001）。对于饲喂FERM_45的仔猪，绒毛形状趋于有利（P<0.10）。本研究表明，给断奶仔猪饲喂部分发酵的液体日粮可能是一种防止断奶后黏膜结构出现不良变化的理念。
