The data in Table A.4. in the References Tables for the Livestock
GREET Tool is pretty out of date. The EPA typically release updated
defaults every year in April in their annual GHG Inventory. Their
latest release is here:

(see Table A-185) - you will need to convert to kg/day/1000kg of
animal mass. Seems they have changed these updates to every two
years with the next one due to come out in April 2019. Wanted to
pass on to see if you could update these given that the GREET Tool
may not be updated until the early 2020s by which time the defaults
might be 10 years out of date.
