Abstract：

    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.
