Development of a fiber supplement to improve fiber digestion in ruminants

本研究旨在探索天然纤维源，以激活瘤胃纤维分解菌，促进反刍动物对主要饲料的消化。我们已经成功地鉴定出瘤胃细菌琥珀酸纤维杆菌在稻草的消化中起着突出的作用，并且该细菌通过补充扁豆和鹰嘴豆壳而被显著激活。以下绵羊饲养试验表明，在稻草日粮中添加10%的每种稻壳可使酸性洗涤纤维的消化率提高3- 6%。从这些可以看出，这些壳可以是反刍动物的助推器纤维补充剂。

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.
