National audienceRuminants are sometimes accused of contributing greatly to the greenhouse effect due to their methane production of digestive origin. Daily methane emissions of most types of cattle were determined using respiration chambers. Animal methane emissions of digestive origin by dairy and beef cattle in France were calculated taking into account the various types and levels of animal production, variations in feeding regimen along the year and the number of bovines in each category in 1993. Yearly methane emission by a dairy cow ranges from 140 to 160 m3 for milk yields ranging from 3400 to 6500 kg per year. Methane production decreases from 41 to 25 l/kg milk for the same range of milk yield. Yearly methane emission averages 120...
