2013 : Addition of lignocellulolytic enzymes into rice straw improves in vitro rumen fermentation products

Prof. Dr. Ir. Sarwoko Mangkoedihardjo MScES


This study aimed to assess lignocellulolytic enzymes in rice straw with an attempt to improve in vitro rumenfermentationproducts. The products were volatile fatty acid, acetate, propionate, butyrate, and ammonia. The experimental methods used completely randomized design with five treatments and five replicates. Five treatments consisted of various levels of lignocellulolytic enzymes and bacterial lignocellulolytic in addition to control, which was no enzymes addition. The results revealed there were significant difference of all the fermentation products. The new finding was an amount of 5% lignocellulolytic enzymes resulted in optimal products of volatile fatty acid and ammonia.
