Effects of Selected Lactobacillus plantarum as Probiotic on In vitro Ruminal Fermentation and Microbial Population


Probiotics are widely used in ruminant production, but information about the potential of Lactobacillus plantarum (L. plantarum) as a probiotic for ruminants is still limited. The aim of

Survival of Lactobacillus plantarumU40 on the in vitro rumen fermentation quantified with real-time PCR.


Activation of inoculum microorganism from dairy cattle feces


Coal produces Coal Bed Methane (CBM) which is formed both biogenically and thermogenically. Lignite is not utilized optimally because it has low heat content and productivity time limit

The impact of anaerobic microorganisms activities in ruminant waste and coal

Enhancement of Biogas Production from Dairy Cow Feces Through Purification Technique


This research consisted of two stages: biogas production from dairy cow feces and purification technique on biogas produced in previous stage. The first stage observed production of biogas

Characteristic of different level of fermented concentrate in the rumen metabolism based on in vitro


Digestibility is a description of the ability of feed material that can be utilized by livestock. Higher digestibility of feed material means the total amount of feed content
