Impact of Mangrove Leaves (<i>Rhizophora apiculata</i>) in Limewater on Nutrients Digestibility, Rumen Ecosystem and <i>in vitro</i> Methane Production

The Mangrove is one of the plants that live in coastal areas, because a lot their availability, mangrove leaves can be used as animal feed. problem with this contained fairly high tannin which harmful to livestock. This study aims determine impact boiled (Rhizophora apiculata) lime water on tannins, digestibility, rumen characteristics, and vitro methane production. design was randomized block using 4 treatments 5 replications. were respective concentrations quicklime follows, P1 (without boiling), P2 (5% water), P3 (10% P4 (15% water) for 10 min. results showed boiling 5% highly significant (p<0.01) total tannins content, nutrient fluid reduced gas content. Nutrient digestibility includes among others: Dry matter (65.18%), organic (66.31%), crude protein (67.90%), increased fiber fractions including NDF (59.01%), ADF (55.75%), cellulose (64.02%), hemicellulose (69.61%) characteristics such NH3 contents (4.32 Mg/100 mL) VFA content (130.2 mm) Methane (231.39 mL/gDM). concluded at concentration min contributed most prominent (4.54%) nutrients.
