Seaweeds and seaweed-ingredients to reduce enteric methane emissions from pasture based sheep, cattle and dairy cows


The drive to become more efficient is viable and well in the food industry and this trend has been altered in recent years by the challenge of making our advancements more environmentally friendly. Meat and dairy production have become targets of much scrutiny and blame in the charge against global warming. By 2050, the EU aims to cut its emissions by 80-95%. Livestock are responsible for 44 % of all methane emissions and methane has 36 times the global warming potential of carbon dioxide. Recent research in Australia demonstrated that feeding the seaweed Asparagopsis taxiformis to sheep at 2% the dry weight of feed resulted in 50- 70% less methane release over a 72-day period continuously. SEASOLUTIONS will investigate the potential of native, harvested seaweeds to reduce enteric methane emissions from sheep, beef and dairy cattle. It will help to gain a fundamental understanding of the mechanism of action of methane reduction in the rumen; effects on animal health and foods produced and the economic, economic viability of using seaweed components to reduce methane emissions.
