[Rural Development Administration Newspaper=Reporter Park Hyun-ryul] As discussions continue regarding the establishment of domestic customized livestock greenhouse gas emission factors, the development of low-methane feed materials, and related research on methane reducers, attention is being paid to whether low-methane feed can be registered using domestic technology. The National Institute of Animal Science under the Rural Development Administration recently completed the registration of 17 types of national unique greenhouse gas emission factors to accurately calculate the methane gas generated during the digestion process of major livestock such as cattle and pigs, tailored to the domestic farming environment. Additionally, a feed material called "thiamine diphosphate" has been developed using domestic technology, which can reduce methane generated during the fermentation process in Hanwoo cattle by 18%.
