Researchers in regional NSW say cattle that ate the additive had methane emission reductions of up to 99 per cent.
A Dutch product is providing some tough competition for a methane-busting seaweed, asparagopsis, being developed in Australia to reduce emissions in cattle.Independent research is being conducted by the University of New EnglandGlobal science giant DSM has been developing the Bovaer additive for 10 years in trials around the world.
In Australia it reduced emissions in beef cattle in a feedlot by up to 99 per cent using a higher dose.DSM's Switzerland-based chemist, Maik Kinderman, said Bovaer was produced from a bio-based alcohol and a nitrate acid."As of today we have finished over 65 feeding trials in 18 countries." When asked to account for the Australian results, DSM said the extent of methane reduction was determined by the amount of Bovaer used and the type of diet or ration fed to the cattle.
She said the study was robust but using up to four times the amount of Bovear per dose does made it more expensive."In terms of feedlot animals though, I guess it is one of the lesser options to reduce overall methane because it is already pretty efficient.
