This study aimed to determine the chemical composition and gas production based on fermentation in the rumen of nine types of forage tropical feed commonly used, named mahogany (Swietenia mahagoni L. Jacq.), tayuman (Bauhinia purpurea), bamboo (Bambusa arundinaceae), canary (Canarium) indicum L.), tea (Camellia sinensis), ketapang (Terminalia catapa L.), lamtoro (Leucaena leucocephala), tehtehan (Duranta repens), and turi (Sesbania grandiflora). Measurement of gas production in vitro was carried out at 7 observation points of hours (2, 4, 8, 16, 36, 48, 72). Tannin activity was measured using measurements of gas production divided into three groups with modified levels of polyethylene glycol (PEG), i.e., samples without PEG (P1); sample + PEG in the amount of 200 mgDM (P2); and PEG + samples of tannins contained in each forage based on literature studies (P3). The total content of tannin varied between 0.20-13.80. The most optimal measurement of gas production was in the sample given PEG of 200mg/kg with a significant difference (P<0.05). From the result, it was found that the higher the tannin content, the lower of gas produced. The addition of PEG was proven to be able to optimize the digestibility value seen from the higher gas production. © 2021 Trans Tech Publications Ltd, Switzerland.
