INTRODUCTION QUESTION #6: The key feature of seaweeds mentioned in the text that may impact methane production by rumen methanogens is the presence of bioactive compounds such as bromoform and dibromoacetic acid, which have been shown to inhibit the activity of methane-producing microbes in the rumen.
METHODS QUESTION #3: The specific parameters measured daily during and after the treatment period in the study involving the cows were methane emissions, milk production, milk composition, dry matter intake, and body weight.
DISCUSSION QUESTION #7: Researchers propose reducing enteric methane emissions in livestock by including seaweed, such as Asparagopsis armata, in their diet, as it has been shown to reduce methane emissions by over 50 percent. Other alternative methods that have been successful in decreasing methane levels in animals include dietary additives, such as fats and oils, tannins, nitrate, and 3-nitrooxypropanol.
