Question 7: How do researchers propose reducing enteric methane emissions in livestock, and what alternative methods have been successful in decreasing methane levels in animals?

Researchers propose reducing enteric methane emissions in livestock primarily by utilizing feed additives, such as seaweed, specifically species like Asparagopsis that contain bromoform, a compound known to inhibit methanogenic pathways in the digestive system. Alternative methods that have shown success in decreasing methane levels in animals include the inclusion of legumes, fats, and concentrates in diets, as well as modifications in grazing strategies to optimize forage consumption without increasing methane outputs. These methods aim to enhance feed conversion efficiency, ultimately contributing to lower greenhouse gas emissions while maintaining livestock productivity.
