Abstract

Kumpai tembaga grass was already known to be one of ruminant animal feed and kumpai tembaga grass grows much in swamp. Kumpai tembaga grass contains high coarse and lignin fibers that can lead to kumpai tembaga grass difficult to digest. The utilization of agricultural waste and the by-products of palm oil waste processing has the potential to improve the quality of kumpai tembaga grasses, such as palm oil sludge and cassava leaves. The high nutritional content of cassava leaves and palm oil sludge as well as the abundant availability of cassava leaves and palm oil sludge has the potential to be used as feed supplement. Palm oil sludge contains unsaturated fat which has the potential as a source of carbon for the growth of rumen bacteria, cassava leaves with potential high protein content are used to increase ammonia needed by rumen bacteria. This study was conducted to determine the population of rumen bacterial on kumpai tembaga grass based ration with combined cassava leaves, palm oil sludge and yeast supplemented by in vitro. The research was held from November to December 2017 at Nutrition and Feed Laboratory of Agriculture Faculty, Animal Science majors, Sriwijaya University, Indralaya. The method used was experimental method with 4 samples. Treatments of R0 as control (85% Kumpai tembaga grass + 15% Concentate), R2 (55% Kumpai tembaga grass + 30% Cassava leaves + 15% Concentrate + 0,05% Yeast (Saccharomyces cerevisiae)), R2 (55% Kumpai tembaga grass + 30% Palm oil sludge + 15% Concentrate + 0.05% Yeast (Saccharomyces cerevisiae)), and R3 (55%Kumpai tembaga grass + 15% Palm oil sludge + 15% Cassava leaves + 15% Concentrate + 0.05% Yeast (Saccharomyces cerevisiae)). The variables observed were total bacterial population, cellulolytic bacteria, amylolytic bacteria, and proteolytic bacteria. The results showed that the highest total bacterial population was R3, the highest cellulolytic bacteria were R1 and R3, the highest amylolitic bacteria was R2, and the highest proteolytic bacteria was R2. The combination rations of kumpai grass, cassava leaves, palm oil sludge, and yeast supplementation increase the total bacterial population in the rumen. Population of cellulolytic, amylolytic, and proteolytic bacteria increased after combination treatment and supplementation. The conclusion of this study was different ration compositions had different rumen bacterial profile compositions.
