A short term enteric methane emission measurement is not identical to a measure of daily methane production (DMP) made in a respiration chamber (RC). While RC curtail most variation except that from quantity and composition of feed supplied. all short-term measurements contain additional sources of variation. The points of difference can include measurement time(s) relative to feeding. https://thegreensjunglebeautyshops.shop/product-category/liquid-eyeliner/
