    Haque et al. (2014) applied this method, using a fixed heat increment factor. Hellwing et al. (2013) regressed open-circuit chamber measurements of DMP in cattle against estimates calculated using CH 4:CO 2 ratios and found them to be only moderately correlated (R 2 = 0.4), which suggest this method is unsuitable for precision measurements.
