Description
Productivity of pasture consisting of both unimproved and improved areas was investigated in terms of conversion efficiency of solar energy into products and nutrient intake of animal. It was shown that animal production is mainly supported by the improved area in spring and late-autumn while the production is supported together by both areas in summer by reasons of increases in productivity of the unimproved area and productive depression in the improved area. CP/DE balance of grazed herbage was close to the requirement ofthe animal in the case where the unimproved area was grazed with the improved area rather than in the case where the improved area only was grazed. Therefore, it appears that the use of the unimproved area with the improved area is more advantageous to stabilize seasonal animal production, to extend the available term per year for grazing and to supply nutrition required by animals than the use of unimproved area alone.
