An experiment had been conducted in order to evaluate the effectiveness of lipid protection of several Indonesian feeds from rumen microbial attacked (hydrogenation) using fornialdehyde. The experiment used the randomized block design in factorial. The first factor was feeds (Kernel Palm Oil MealIKPOM, Yellow CornIYC, Rice BranIRB, and Pasture Grass Brach~arlci humidicola/BH); the second factor was level of fonnaldehyde used (0, 2.5, 5, 7.5, and 10'Yo of' Crude Protein of Feed); the third factor was storage time of processed feeds (0,2,4, and 6 days after addition of formaldehytle). The main parameter measured in this experiment is hydrogenation of several unsaturated fatty acids (OleatlCI8:l; Linoleat/CI8:2; and Linolenat/CI8:3) and degradation of Feed Protein; using Tilley and Terry in vltvo technique; digestibilities (Dry Matter and Organic Matter), VFA production and Total Gas Production. The results of the experiments showed that hydrogenation of Oleat was decreased (Pc0.05) with 1 0°/(, formaldehyde for 6 days storage time for RB, BH, KPOM, and YC; hydrogenation of Linoleat and Linolenat was descreased (Pc0.05) with 7.5% fonnaldehyde for 4 days storage time for BH, KPOM, RB, and YC. The NH3 and VFA production during 4 hours incubation was decreased (P<0.05) at 10% level of formaldehyde, for 6 days storage time. Total Gas Production decreased with 7.5% formaldehyde in 4 days time of storage for KPOM. It was concluded that lipid protection from hydrogenation by rumen microbes in this experiment was possible.
