Manure from all grazing cattle managed dry. Portion of manure from stall-fed cattle managed wet estimated from Safley et al. (1992) and USEPA (1994). Methane Conversion Factors (MCFs) from USEPA (1994) based on approximate temperature regime and type of liquid manure management facilities typically used in each region. MCFs marked with “*” are not used in the analysis because all manure is estimated to be handled in a dry form. The average MCFs for dairy cows and other cattle are estimated by weighting the dry and wet regional MCFs by the appropriate portions of manure managed in dry and wet forms.
