Commercialising this idea is a major win for the CSIRO. It was first posted on IdeaSpies over a year ago https://ideaspies.com/posts/food-production-that-is-environmentally-friendly
The CSIRO is commercialising seaweed product found to accelerate cattle growth and cut their hefty greenhouse gas emissions to near zero.
A potential long-term saviour for the global cattle industry, which stands accused of being a bigger greenhouse gas producer than all nations apart from China and the United States.
A significant body of research shows adding even small amounts of the seaweed product to cattle diets can cancel out methane emissions – through burping and flatulence – while the reduction in digestion waste results in faster growth rates (an average of 20% increase in field trials).
