Research groups are planning to commercialize red seaweed (Asparagopsis) as a cattle feed additive, potentially reducing methane production in cows. A study found that this seaweed can prevent the formation of methane in the digestive tract, without affecting milk or meat quality. The active ingredient, bromoform, seems stable even after freezer storage for three years. The additive may also reduce farmers' forage needs by 14%. Commercialization is expected within the next 12 months.
