Corrigendum to “A new approach for improving emission factors for enteric methane emissions of cattle in smallholder systems of East Africa – Results for Nyando, Western Kenya” [Agricultural systems volume (161) pp72–80]

The authors regret that a recent examination of our data for other purposes has led to the discovery of an error in the calculation of the Metabolic Energy Requirement for maintenance (MERm) in the original calculations of this article. This was occasioned by the application of an incorrect constant to the calculation of MERm to male animals >2 yrs., male animals 1-2 yrs. and calves and had the effect of increasing the Emission Factors (EF) for these classes of animals by 3–29%. The corrected table of EFs for all classes of animal is reproduced directly below.
