A series of studies to explore natural fiber sources were carried out for leading activation of fibrolytic rumen bacteria and concomitant improvement of main forage digestion in ruminants. We have successfully identified that the ruminal bacterium Fibrobacter succinogenes plays a prominent role in digestion of rice straw and this bacterium is significantly activated by supplementing lablab bean and chickpea husks. The following feeding experiment using sheep has revealed that 10% supplementation of each husk to rice straw diet improves digestibility of acid detergent fiber by 3-6%. From these it is apparent that these husks could be a booster fiber supplement in ruminants.

进行了一系列探索天然纤维来源的研究，以引导纤维化瘤胃细菌的激活以及反刍动物中主要草料消化的伴随改善。我们已经成功地确定，瘤胃纤维杆菌琥珀酸酯在消化中起着重要的作用，并且通过补充Lablab Bean和鹰嘴豆果皮来显着激活该细菌。使用绵羊的以下进食实验表明，将每种果壳补充10％可将酸洗涤剂纤维的消化率提高3-6％。从这些角度来看，这些果壳可以是反刍动物中的增强纤维补充剂。
