Effects of Supplementation of Piper sarmentosum Leaf Powder on Feed Efficiency, Rumen Ecology and Rumen Protozoal Concentration in Thai Native Beef Cattle

This work was to study the influence of Piper sarmentosum (PS) leaf powder supplementation in cattle diet. It was found that supplementation of PS leaf powder at 2.4 g/d resulted in improving total feed intake and dry matter (DM) digestibility whereas there was reduced protozoal population and methane (CH4) production in cattle
