成年母猪的胃肠道系统比年轻的生长猪更发达，因此消化纤维成分的能力上级。本研究的主要目的是描述母猪和生长猪消化浓缩低膳食纤维（DF）日粮和两种高DF日粮中纤维成分的能力，这两种高DF日粮DF相似，但DF溶解度不同。6头母猪和4头生长猪在回肠末端安装了简单的T型插管。每个平衡实验包括7天的初始期，随后分别收集生长猪和成年母猪的3天粪便和2天或3天回肠粪便。当饲喂高比例的可溶性非淀粉多糖（NSP）时，生长猪和成年母猪之间的发酵能力差异较小。成年母猪表现出较高的发酵能力，证明了较高的发酵和较高的甲烷产量，当高纤维饲料与高量的不溶性纤维喂养。(c)2007 Elsevier B.V保留所有权利。
Adult sows have a more developed gastro-intestinal system than young growing pigs resulting in a superior capacity to digest fibrous components. The main objective of this study was to describe the capacity of sows and growing pigs to digest the fibre components in concentrated low dietary fibre (DF) diet and two high DF diets similar in DF but with contrasting DF solubility. Six sows and four growing pigs were fitted with a simple T-cannula at the terminal ileum. Each balance experiment consisted of a 7-day initial period followed by a 3-day collection of faeces and a 2 or 3-day collection of ileal digesta for growing pigs and adult sows, respectively. When feeding diets with high proportions of soluble non-starch polysaccharides (NSP), the difference in fermentation capacity between growing pigs and adult sows was small. The adult sows showed a higher fermentative capacity, evidenced by a higher fermentation and a higher methane production, when high fibre diet with high amount of insoluble fibre was fed.
