Evaluation of the use of plant organic components and probiotics on ruminal characteristics and as a decrease of methane

Abstract

The reduction of CH4 from the digestive tract of ruminants can be done through the use of organic components of plants such as tannins and saponins and the use of probiotics. This study aims to evaluate the addition of organic components and probiotics to the characteristics of rumen fluid and its ability to reduce CH4 in Ongole Cross Breed (PO) cattle. Sengon (Paraserianthes falcataria) leaf meal and Trembesi (Samanea saman) leaf meal are used as organic components due to their tannin and saponin content. Probiotics contain Acetoanaerobium notarae and Saccharomyces cereviseae. This research used total mixed ration as a feed. A total of 24 heads PO cattle were divided into 4 treatments, ie T1 = control treatment; T2 = T1 + organic components, T3 = T1 + Probiotics and T4 = T1 + organic components + probiotics. The research design was a randomized block design. The combination treatment of the addition of organic components and probiotic caused a decrease in the ratio of acetic acid to propionic acid (C 2 :C3), percentage of acetic acid, the concentration of CO2 and CH4, but increases the percentage of propionate acid. The combination of organic components and probiotics is the greatest decrease in CH4 production from enteric fermentation.
