Question 1: What is a method mentioned in the text to lower enteric methane emissions from livestock?
Correct Response: Using seaweed as feed additives
Question 2: Which compound occurs naturally in the ocean and is the primary anti-methanogenic compound in Asparagopsis?
Correct Response: Bromoform
Question 3: What is the role of bromoform in the context of livestock greenhouse gas emissions?
Correct Response: Inhibits methanogenic pathway
Question 4: What is the primary anti-methanogenic compound in Asparagopsis?
Correct Response: Bromoform
Question 5: Why might the taste of feed additives impact Dry Matter Intake (DMI) in animals?
Correct Response: increased feed conversion efficiency
Question 6: What was the expected impact on feed conversion efficiency in cows fed diets high in A. armata?
Correct Response: increased efficiency
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.
