The objective of this study is to determine the effect of supplementation of a mixture of dried carboxylic salt (DCM) protected by fatty acids in fermented feed on nutritional values and fermentation characteristics and ammonia concentration. Rumen liquid, sago waste, rice bran, fish waste, and sap liquid are used as material. The total ration mixture formulation is based on fermented feed and DCM supplements as follows: R0 (40% rice bran, 40% fermented sago waste, 20% tofu waste R1 (40% fermented rice bran, 40% fermented sago waste, 20% commercial concentrate), R2 (R1 + 1.5% DCM) R3 (R1 + 3% DCM) and R4 (R1 + 4.5% DCM) The nutritional value of fermented feed obtained by DCM supplementation was significantly different between treatments, supplementation 1.5-4.5% DCM significantly increased dry matter, ash, and ether extract. DCM supplementation significantly reduced crude fibre and not in crude protein. The addition of DCM increases the dry matter, ash, and ether extract and decreases crude fibre and does not affect the crude protein. The addition of DCM in ration decreases rumen pH but increases total VFA and N-NH3 ammonia concentration.
