Temperate seaweeds Himanthalia elongata and Fucus vesiculosus significantly reduce rumen methane emissions in vitro due to their high phlorotannin content.

ABSTRACT:

Background

Global food insecurity and the fact that food production contributes around 30% of greenhouse gas (GHG) emissions is a major planetary challenge. Ruminant products are widely consumed since they are macro- and micronutrient dense; however, ruminants produce enteric methane (CH₄), a potent GHG. Feeding seaweeds, such as Asparagopsis spp., to ruminants reduces enteric CH₄ emissions. This study investigates the CH₄ mitigation potential of seaweeds, including Alaria esculenta (AE), Ascophyllum nodosum (AN), Asparagopsis taxiformis (AT; positive control), Chondrus crispus (CC), Fucus vesiculosus (FV), Himanthalia elongata (HE) and two seaweed-derived extracts - Himanthalia elongata (XHE), and Chondrus crispus (XCC) - on rumen fermentation (CH<
