RUMEN METABOLIT OF BALI CATTLE FED FERMENTED RATION BY BALI CATTLE COLON AND ORGANIC WASTE LIGNOCELLULOLYTIC BACTERIA INOCULLANT

Abstract

This study aimed to in-vivo analyze the level of rumen fermentation of Bali cattle fed fermented rations by 3 types of lignocellulolytic bacterial inoculants from the Bali cattle colon and organic waste produced by Mudita et al. (2015) namely: inoculants with code BS₁₂K₁₂; BS₁₂K₁; and BS₁K₁₂.The research held at The Research Station Education Farm, Bukit Jimbaran, Badung, Bali and Laboratory of Nutrition and Feed Animal, Faculty of Animal Husbandry, Udayana University in 3 (three) months, with 4 (four) total collection periods. The research has been done by The Latin Square Design, with 4 (four) treatment and 4 periode researching as replicated. The treatments were: RB₀ = bali cattle fed ration fermented without bacteria innoculant (fermented molasses solution as control), RB₁=bali cattle fed ration fermented bacteri innoculant BS₁₂K₁₂, RB₂=bali cattle fed ration fermented bacteri innoculant BS₁₂K₁, and RB₃=bali cattle fed ration fermented bacteri innoculant BS₁K₁₂. The observation variables on this research are: pH, protozoa population, totally VFA and partial such as acetic acid, propionic acid, and butiric acid, and N-NH₃ on the rumen fluid. The result of this research shows that the bali cattle fed ration fermented by inocullant of bali cattle colon and organic waste lignocellulolytic bacteria had increased (P<0,05) the rumen metabolism rate of bali cattle, especially N-NH₃, propionatic acid and totally VFA, without effecting the pH and population of protozoa on the bali cattle rumen liquid.
