A new approach for improving emission factors for enteric methane emissions of cattle in smallholder systems of East Africa Results for Nyando, Western Kenya

This study developed an alternative methodology based on animal energy requirements derived from field measurements of live weight, live weight change, milk production and locomotion to estimate intake. Researchers used on-farm data to analyze feed sample to produce estimates of digestibility by season and region, then and used these data to estimate daily methane production by season, area and class of animal to produce new emission factors (EF) for annual enteric CH4 production.
