Oilseeds can be used to manipulate ruminal fermentation for attaining cleaner and better production. The effect of feed-grade niger seeds was studied on in vitro rumen fermentation parameters in comparison to sunflower seeds. Methane production decreased (P ≤ 0.01) with incorporation of both seeds. In vitro digestibility of dry matter and organic matter reduced at higher incorporation levels (above 5%, DM basis). Fermentation pattern of niger and sunflower seed-based total mixed rations was highly comparable. The relatively higher anti-methanogenic potential of niger seeds could make it a better choice for alleviation of enteric methane and formulation of environment-friendly rations.
