The significant diet effect on the interval between feed consumption and methane measurement may have confounded the ability of short-term methane measurements to provide data suitable for accurately estimating methane per unit feed intake. Caution is needed in extrapolating short-term emission measures into daily emission rates when evaluating quick-acting rumen modifiers.  aBOVINOS  aEMISION DE GASES DE EFECTO INVERNADERO  aSUPLEMENTACIÓN  aUREA  aGREENHOUSE GASES  aMEASUREMENT1 aCOTTLE, D.J.1 aHEGARTY, R.S.  tAnimal Production Science, 2014gv. 54, no. 10, p.1737-1740.
