摘要

在6头胃插管妊娠母猪中,研究了饲喂两种不同溶解度的高纤维日粮和低纤维浓缩日粮对胃排空率的影响。此外,还研究了是否有任何影响可能与食糜的物理化学性质有关,即粘度和/或水结合能力。采用3 × 3拉丁方设计,饲喂每种饲粮一周,并在早餐后0.5、1、2、3、5和15.5 h随机取样。胃内容物每日1次通过胃插管排出。对空胃食糜进行定量,并取代表性样品,测定其粘度、水结合能力、干物质、日粮成分、固体(Cr2O3)和液体(聚乙二醇)相标志物的含量。液体食糜的流量以食糜与干物质之差计算。增加饲粮中膳食纤维含量可提高液体食糜的回收率,但对干物质和饲粮成分的胃排空无显著影响。膳食纤维的作用不能归因于食糜液相的粘度,而可能与胃中膳食纤维含量增加的保持水分的能力有关。胃选择性地保留了不溶性膳食纤维成分,最明显的是在麸皮补充饮食中,从2小时起,食糜中不溶性NSP的浓度显著增加。

Impact of diets varying in dietary fibre characteristics on gastric emptying in pregnant sows
The effects of feeding two fibre‐rich diets with contrasting solubility and a concentrated low dietary fibre on the rate of gastric emptying were examined in six gastric cannulated pregnant sows. Additionally, it was examined whether any effect could be related to the physico‐chemical properties of digesta, i.e. viscosity and/or water binding capacity. The sows were fed each diet for one week in a 3 x 3 Latin Square design and the samples were taken in a randomised order 0.5, 1, 2, 3, 5 and 15.5 h after the morning meal. The stomach contents were evacuated through the gastric cannula once daily. The evacuated gastric digesta was quantified and a representative sample was taken to determine its viscosity, water binding capacity and its content of dry matter, dietary components and solid (Cr2O3) and liquid (polyethylene glycol) phase markers. The flow of liquid digesta was calculated as the difference between digesta and dry matter. Increasing the content of dietary fibre in the diet led to higher recovery of liquid digesta but did not have any significant effect on the gastric emptying of dry matter and dietary components. The effect of dietary fibre could not be attributed to the viscosity of the liquid phase of digesta but might be related to the ability of the increased gastric dietary fibre content to hold water. The stomach selectively retained the insoluble dietary fibre components most noticeably seen with the bran‐supplemented diet where the concentration of insoluble NSP in digesta increased significantly from 2 hours and onward.
