A puffy pink seaweed that can stop cows from burping out methane is being primed for mass farming by USC researchers.
The University’s Seaweed Research Group leader Associate Professor Nick Paul said that if Australia could grow enough of the seaweed for every cow in Australia, the country could cut its greenhouse gas emissions by 10 percent.
“When added to cow feed at less than two percent of the dry matter, this particular seaweed completely knocks out methane production. It contains chemicals that reduce the microbes in the cows’ stomachs that cause them to burp when they eat grass.”
The USC team is working at the Bribie Island Research Centre in Moreton Bay to learn more about how to grow the seaweed species, with the goal of informing a scale-up of production that could supplement cow feed on a national or even global scale.
“This seaweed has caused a lot of global interest and people around the world are working to make sure the cows are healthy, the beef and the milk are good quality,” Dr Paul said.
“That’s all happening right now. But the one missing step, the big thing that is going to make sure this works at a global scale, is to make sure we can produce the seaweed sustainably.”
Project scientist Ana Wegner said the team’s challenge was to find the perfect growing conditions to move crops from the laboratory to large outdoor aquaculture tanks.
“We know the chemical composition of Asparagopsis and we know the chemical compounds that actually reduce methane production in cows, so now we want to maximise the concentration of that chemical so we can use less seaweed for the same effect,” Ms Wegner said.
