| Outline of Final Research Achievements |
To develop the novel grazing system both to contribute to conservation of biodiversity and to improve animal production and welfare, the relationships between plant species diversity and nutrient utilization was investigated in four sites in the eastern Asia (Miyagi, Gifu, Hiroshima and Korea). 1. The highly precise evaluation technique to estimate herbage mass and coverage of grazing pasture was established by using aboveground spectral measurements and UAV aerial imaging. 2. The “bite-coding grid” of goats and cattle was established, and by using it, foraging manner of animals were characterized in species-rich grazing pastures. 3. Some forbs and tree leaves contain much minerals and amino acids than grasses, and they contribute to improve digestion of plants in the rumen and nutrient balance in the blood.
