Yes, Asparagopsis is a macroalgae (seaweed) from the genus Rhodophyta (red seaweeds).
The reason cows produce methane is because of a methanogenic bacteria in their digestion system. Asparagopsis contains high levels of bromophenols; bioactive compounds that inside the cow’s rumen binds to the molecule that the bacteria needs to produce methane which inhibits the production.
Adding Asparagopsis to the cows diet not only reduces methane production, it also unlocks energy to be used to increase the cow’s efficiency.
Volta Greentech is developing methods of producing Asparagopsis at scale in aquaculture systems on land. Growing the seaweed in a controlled and high-technological environment enable a clean, safe and efficient production. Volta’s first seaweed factory will be built in Sweden.
When enteric methane emissions are decreased that energy can be used to increase the animal’s efficiency and productivity.
“The main anti-methanogenic compound in Asparagopsis, bromform, is naturally produced by phytoplankton and seaweeds in the ocean. Human consumption of high level of bromoform could be hazardous so the US EPA has set drinking water regulations on bromoform consumption to 80µg/L. Milk produced by cows fed the Asparagopsis additive were in the range of 0.11-1.15µg/L, which is more than 500 times lower than the maximum standard. “
