| Outline of Final Research Achievements |
Cattle production requires large amount of feed used as foods for human and causes unavoidable loss in respiration, feces and urine which may become an environmental burden as contributors to pollution of air, soil and water. Utilization of food processing by-products and reduction of environmental burden were investigated using experimental and systems approaches. Total mixed rations using by-products and recommended cultivar for whole rice crop silage were proposed. Simulation for comparison between year-round grazing and conventional beef fattening systems indicated that economic efficiency and methane emission were undesirable in grazing systems but nitrogen excretion may be reduced by using feed rice with lower CP content. The trade-off analysis between total profit and methane emission by prefecture showed economic loss caused by 1 kg decreased methane emission of 474 yen in Japan. Finally, available methane and nitrogen mitigation policy instruments in Japan were discussed.
