本研究在評估糙米做為畜禽飼料能量原料之可行性，以增加國內糧食安全。試驗探討以不同比例臺中秈17號糙米取代玉米對白肉雞、LD雜交肉豬及DK雜交黑豬生長性能及屠體性狀之影響。0 – 5週齡白肉雞飼養結果顯示，飼糧中以臺中秈17號糙米完全取代玉米，並不會影響肉雞採食量與生長性狀，但飼料糙米取代75%及100%玉米時會致雞肉色澤的降低 (P < 0.05)；以臺中秈17號糙米取代飼料中玉米用量的50%餵飼LD雜交肉豬，在生長期飼料轉換率較高，背脂厚度較薄，而肌間脂肪含量百分比高；在DK雜交黑豬方面，臺中秈17號糙米取代玉米對生長性能（平均日增重、飼料採食及飼料轉換效率）均無顯著影響，但會顯著影響屠肉顏色，因此建議以臺中秈17號糙米取代50%的玉米量，以維持相同的肉品色澤。
The purpose of these serial studies is to evaluate the feasibility of substitution the imported energy feed corn in livestock diets by locally-produced rice so as to promote our feed safety. Taichung Sen No. 17 brown rice was chosen to replace the dietary corn and feed to broilers, LD hybrid pigs and DK hybrid black pigs. In the 5-wk raising period of broilers, feed intake and growth performance of broilers was not influenced even the brown rice 100% replacing the dietary corn. But the higher replacing ratio, 75% and 100%, would decrease the breast color (P < 0.05). In LD pigs feeding trial, 50% replacing ratio group resulted in the better feed conversion efficiency and intramuscular fat percentage but lower backfat thickness during the growing period. In the DK pigs feeding trial, the averaged daily gain, feed intake and feed conversion rate also were not affected by the replacing treatments, but higher replacing ratio did lower their pork color. It is thus suggested, to maintain the same meat color for broilers and pigs 50% of the dietary corn could be substituted by Taichung Sen No. 17 brown rice.
