Résumé	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.	Somatic Cell Count (SCC) is a quantitative measure of the concentration of white blood cells and epithelial cells in milk, used as a primary indicator of udder health and the presence of mastitis in lactating cattle. Standardized by veterinary regulatory agencies worldwide, SCC serves as a non-invasive, cost-effective screening tool in dairy herd management and milk quality assessment.
