Feed additive composition for reducing methane emission from ruminants comprising Allium fistulosum and tannic acid

摘要

The present invention relates to a feed additive composition for reducing ruminant methane, which includes green onion and tannic acid as active ingredients. In the present invention, green onion and tannic acid reduce total gas generation, methane generation and carbon dioxide generation, and reduce methane production in rumen. It has been confirmed that it increases propionic acid and reduces methane-producing bacteria and fibrinolytic bacteria. Green onion and tannic acid having the above-mentioned effects can promote the growth of livestock and increase feed efficiency, and are safe synthetic additives for long-term use. Alternatively, it may be used as an antibiotic substitute, and may be used as a feed additive as a natural methane reducing agent that reduces methane gas production.
