This research work was carried to examine the rate of production of biogas through anaerobic digestion of fresh Cow rumen obtained from slaughter house in Woji, Trans-Amadi, Port Harcourt. The Kinetics of the biogas produced upon the influence of biodegradation was studied using kinetic model linear, power, growth rate decay, non-elementary rate models to establish the model that best predicts the amount of biogas obtained from the experimental obtained parameters. The total solid, volatile solid, ash content and pH was evaluated upon the influence of the biomass. Also, the temperature and pressure build-up during the anaerobic digestion process were recorded weekly. The results of the analysis showed that is, volatile solid, ash content were 0.924g/g, 0.734g/g and 0.1414g/g, while the PH value before and after the analysis were 7.45 and 7.26 as well as fluctuation in temperature between 300C and 34.50C was observed.
