In order to reduce the expense of dry preparation，I compared the general method which dries up in a fresh paddy and the brown rice drying system. The brown rice drying system is using the impeller type husker for high moisture paddy and the recirculating batch type heated air dryer. The drying efficiency, yield rate and feed compositions were compared between the brown rice drying system and conventional method. The brown rice drying system could reduce the working hours, kerosene and electric power consumption required for drying more than 50% compared with a conventional method. Therefore，the charging and discharging operations has drastically improved. In addition, the brown rice drying system could reduce them including husking paddy, then the yield rate did not change. The fiber increased a little with the increase in husk mixture rate，and the total digestible nutrients (TDN) content slightly decreased, but as for other feed compositions, TDN weight and the amino acids contents were not meaningful difference between both systems. The results indicated that the brown rice drying system improved the drying efficiency compared with the conventional method．
