Effect of basal diet and supplement on methane emissions measured using respiration chambers. Methane values are expressed as g per kg dry matter intake (DMI). Methane emissions were significantly lower in concentrate fed compared to forage fed cattle (p < 0.01). Cattle fed forage diets with combined nitrate supplementation showed significantly lower methane emissions compared to forage controls (p < 0.05). Data collected from animals fed a forage-based diet are indicated in blue, and those from animals on a concentrate diet are shown in orange
