一种富含发酵性非淀粉多糖（fNSP）的饲料曾被证明可以稳定限制喂养母猪的葡萄糖和胰岛素水平，并减少其身体活动。稳定的葡萄糖水平可以防止餐间饥饿。本研究的目的是阐明发酵在这些性状中的具体作用，10头空母猪分别饲喂低（l -母猪）和高（h-母猪）饲粮，每天2次，连续3期，先不输注，然后按不同顺序连续在盲肠输注fNSP或在血液中输注葡萄糖，每次8天（GLU，能量对照组）。两种饮食之间的能量输入差异与从fNSP中获得的能量差异相似。在喂食时间之间抽取血液样本，分析葡萄糖和胰岛素水平及其稳定性。录像分析了姿势的变化（身体活动）。GLU和fNSP输注稳定了L型母猪的葡萄糖水平，减少了L型母猪和h型母猪的姿势变化（h型母猪，倾向）。胰岛素稳定性受输注影响较小。GLU和fNSP输注可防止葡萄糖降至基础水平以下。在l型母猪（盲肠）中输注fNSP与在h型母猪（口服fNSP）中输注GLU效果相似。结果表明，发酵在富fnsp日粮对母猪葡萄糖水平稳定性和身体活动的影响中起重要作用。(c) 2005 Elsevier B.V.版权所有
A fermentable non-starch polysaccharides (fNSP)-rich diet was previously shown to stabilise glucose and insulin levels and reduce physical activity in restricted-fed sows. Stable glucose levels may prevent interprandial hunger. Aim of the present study was to elucidate the specific role of fermentation in these traits,Ten empty sows were either fed a low- (L-sows) or a high-fNSP diet (H-sows), twice daily In three successive periods, sows received first no infusion and then, in different sequences, continuous fNSP infusion in the cecum or glucose infusion in the blood for 8 days each (GLU; energetic control). Infused energy was similar to the difference in energy derived from fNSP between diets. Blood samples, drawn between feeding times, were analysed for glucose and insulin levels and stability. Videorecordings were analysed for posture changes (physical activity).GLU and fNSP infusions stabilised glucose levels in L-sows and reduced posture changes in both L- and H-sows (H-sows, tendency). Insulin stability was less affected by infusions. GLU and fNSP infusions prevented drops of glucose below basal levels. fNSP infusion in L-sows (cecum) had similar effects as GLU infusion in H-sows (oral fNSP intake).Results imply that fermentation plays an important role in the effects of a fNSP-rich diet on the stability of glucose levels and physical activity in sows.
