Outline of Final Research Achievements

Phytanic acid, which has beneficial effects on human health, is produced from phytol moiety of chlorophyll through the action of ruminal microbes, and appears in milk and meat of ruminants. In this study, we found the variation in chlorophyll or phytol contents in various forages, which affected phytanic acid production in the rumen, and variation in phytanic acid content in milk of cows fed various diets. We further found that phytanic acid affected lipid metabolism in ruminants.
