Extract

Methane is an unavoidable product of rumen fermentation. Reduction of rumen methanogenesis can lead to an improved exploitation of nutrient energy and a decrease of methane emissions in the environment. The objective of this study was to investigate the effect of several fat and tannin containing feedstuffs on the production of CH4 and concommitant CO2 using the in vitro system „Hohenheim Gas Test” (STEINGAß & MENKE 1986). Special emphasis was directed to the suitability of the method to measure the effect of various substrates on rumen methanogenesis. Another objective was to investigate to what extent increasing fat or tannin contents in the diet of the donor sheep affect methanogenesis in vitro.
