    KEGG pathways associated with methane metabolism. Highlighted EC gene numbers are those genes that differed significantly between high and low emitting cattle. Red – genes that had higher abundance in high emitters; blue - genes that had lower abundance in high emitters. (DOC 22 kb

    Distribution of methane emissions and archaea:bacteria ratios within breed type and diet.

    <p>The box plot shows the large variation and range of methane emissions (per day or per kg DMI = dry matter intake) and archaea:bacteria ratios within crossbred breed type (AA = Aberdeen Angus sired, LIM = Limousin sired) and diet (CON = concentrate based diet, FOR = forage based diet). The total number of animals in the 2 × 2 factorial design experiment was 68.</p

    Heatmap of the relative abundance of microbial genes associated with methane emissions as identified in the partial least squares analysis.

    <p>The relative abundance of microbial genes (blue = low to yellow = high) changed depending on methane emissions (g/kg DMI) for the animals selected for low and high methane emissions within breed type and diet. The labels on the horizontal axis indicate the crossbred breed type (AA = Aberdeen Angus sired, LIM = Limousin sired), diet (CON = concentrate based diet, FOR = forage based diet) and the amount of methane emissions (g/kg DMI).</p

    Host genetic effects on methane emissions and relative microbial abundance.

    <p>Host genetic effects were estimated by least squares means (± standard errors, different letters above bars indicate significant different estimates) of sire progeny groups (AA = Aberdeen Angus sired, LIM = Limousin sired) adjusted for diet, respiration chamber and randomized block effects. Relative microbial abundance was calculated as archaea:bacteria ratio.</p
