Researchers from the College of the Sunshine Coast (USC) are learning a sort of seaweed that stops cows from expelling methane. The puffy pink seaweed known as Asparagopsis grows abundantly alongside the Queensland coast and is at present being primed for mass farming.
USC Seaweed Analysis Group chief Affiliate Professor Nick Paul mentioned that if Australia might develop sufficient of the seaweed for each cow in Australia, the nation might lower its greenhouse gasoline emissions by 10%.
“Seaweed is one thing that cows are recognized to eat. They are going to really wander right down to the seaside and have a little bit of a nibble,” Dr Paul mentioned.
“When added to cow feed at lower than 2% of the dry matter, this specific seaweed utterly knocks out methane manufacturing. It accommodates chemical substances that cut back the microbes within the cows’ stomachs that trigger them to burp after they eat grass.”
The seaweed’s potential to mitigate methane manufacturing was described in a CSIRO-led examine in 2014. The USC staff is working on the Bribie Island Analysis Centre in Moreton Bay to study extra about find out how to develop the seaweed species, with the intention of upscaling manufacturing in order that it may be added to cow feed on a nationwide, or probably world, scale.
“This seaweed has prompted loads of world curiosity and folks around the globe are working to verify the cows are wholesome, the meat and the milk are good high quality,” Dr Paul mentioned.
“That’s all taking place proper now. However the one lacking step, the large factor that’s going to verify this works at a world scale, is to verify we are able to produce the seaweed sustainably.”
Mission scientist Ana Wegner mentioned the staff’s problem was to search out the right rising situations to maneuver crops from the laboratory to giant out of doors aquaculture tanks.
“We all know the chemical composition of Asparagopsis and we all know the chemical compounds that really cut back methane manufacturing in cows, so now we need to maximise the focus of that chemical so we are able to use much less seaweed for a similar impact,” Wegner mentioned.
