This study aims to determine the availability of feed ingredients, types and diversity as well as the proportion, relation to digestibility, VFA production and N-NH3 for Bali cow holding in the group "Simantri" program  in Bali on the different topography. Retrieving data using the method of observation at 27 group "Simantri", at 3 altitude / topography (lowland, medium and high). Variables measured: feed amount given, type and diversity of feed ingredients and proportions, sampling of feed materials, and take the liquid contents rumen. Sampling feed material to determine the nutrient content and digestibility of the ration, while knowing VFA rumen fluid contents (total and partial) and N-NH3.  The results showed the higher the percentage of a natural grass in the lower ration. This condition causes the higher topography and diversity of the types of feed materials more and more.  The proportion of shrub legume Gliricidia leaves of trees, especially in the diet is relatively small (6.6%), while the potential of Gliricidia leaves pretty much at all altitude. Judging from the fulfillment of nutrients, Bali cow rations at all topographic meet the needs/head/day in the range of 6.10 to 8.14 kgDM, protein (CP) ± of 750,2g  and energy ± 12 526 kcal ME.  In the test VFA rumen fluid obtained from 71.68 to 85.07 mMol in the category enough, while N-NH3: 5,21-6,11mMol still relatively low .  From this study we can conclude supply of feed for Bali cow in the group "Simantri" program in Bali nutrient content rations have to meet the needs.  The higher the proportion of legume shrub tree (Gliricidia leaves) the digestibility, VFA production and N-NH3 getting better.
