|Abstract: ||The objective of this study was to develop emission factors (EF) for methane (CH4) emissions from enteric fermentation in cattle
native to Benin. Information on livestock characteristics and diet practices specific to the Benin cattle population were gathered
from a variety of sources and used to estimate EF according to Tier 2 methodology of the 2006 Intergovernmental Panel on
Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories. Most cattle from Benin are Bos taurus represented by
Borgou, Somba and Lagune breeds. They are mainly multi-purpose, being used for production of meat, milk, hides and draft power
and grazed in open pastures and crop lands comprising tropical forages and crops. Estimated enteric CH4 EFs varied among cattle
breeds and subcategory owing to differences in proportions of gross energy intake expended to meet maintenance, production and
activity. EFs ranged from 15.0 to 43.6, 16.9 to 46.3 and 24.7 to 64.9 kg CH4/head per year for subcategories of Lagune, Somba
and Borgou cattle, respectively. Average EFs for cattle breeds were 24.8, 29.5 and 40.2 kg CH4/head per year for Lagune, Somba
and Borgou cattle, respectively. The national EF for cattle from Benin was 39.5 kg CH4/head per year. This estimated EF was
27.4% higher than the default EF suggested by IPCC for African cattle with the exception of dairy cattle. The outcome of the study
underscores the importance of obtaining country-specific EF to estimate global enteric CH4 emissions.|
