tendency toward significanceP < 0.1
Daily enteric methane production in the Australian population measured as grams per day (MeP Australia ; g/d) was significantly influenced by cohort ( P < 0.001), dry matter intake (DMI; P < 0.001), and live weight ( P < 0.05), with days in milk (DIM) showing a tendency toward significance ( P < 0.1; Supplementary Table 1 ).
