Rumen In Vitro Gas Production
The In Vitro Gas Production (IVGP) assay is a laboratory method that measures the fermentation kinetics of animal feeds by incubating feed samples with rumen microorganisms in controlled conditions and monitoring the volume of gas produced over time. Developed by Theodorou and colleagues in 1994, IVGP provides rapid, cost-effective estimates of feed nutritive value, digestibility, and energy availability, making it valuable for feed evaluation, diet formulation, and research on rumen fermentation dynamics.
