Abstract

Cattle diet can impact manure quality and quantity but has minimal impacts on methane production from anaerobic digestion of manure. Quality of manure, measured as OM, does affectmethane production and is largely impacted by the environment cattle are housed in and methods used to collect manure. As the amount of ash contamination of manure was increased, or OM content of the manure was decreased, organic matter degradation and methaneproduction were decreased. With adequate daily cleanout of ash from digesters, open-lot beef cattle manurecan be used for anaerobic digestion.
