Feed supplements such as red seaweed or Bovaer®10 can significantly reduce methane emissions
In Australian feedlot research trials, Asparagopsis taxiformis (red seaweed) and Bovaer®10 have reduced methane between 15 - 90% when fed daily to cattle1. Just ¼ tsp of the Bovaer®10 in a cow’s daily feed of 15–20kg takes effect in as little as 30 minutes. As it acts, Bovaer®10 is safely broken down into compounds already naturally present in the rumen or normally present in the animal. Research is underway to understand their potential for grazing cattle.
