Rice bran has been shown to lower serum cholesterol in hamsters. Leghorn cockerel chicks were fed 60% full-fat rice bran (FFRB) and corn/soy (CS) diets with 0.5% added cholesterol. Both diets contained 18% protein. All reported parameters are on blood serum. Significant differences (p less than 0.05) were found in total cholesterol (TC), triglycerides (TG), high-density and low-density lipoprotein cholesterol (HDL and LDL). In a second study, chicks were fed FFRB, defatted rice bran (DFRB), and CS diets balanced for 18% protein, 14.47% total dietary fiber and 10.78% lipid with 0.5% added cholesterol. Both TC and TG were significantly lower (p less than 0.05) in chicks fed FFRB and CS diets. Significant differences were found in HDL values for all diets with FFRB exhibiting the highest mean value (155 mg/dl) and CS exhibiting the lowest mean value (114 mg/dl). All diets were significantly different (p less than 0.05) in LDL, with mean values of 249, 318 and 275 mg/dl for FFRB, DFRB and CS, respectively. FFRB appears to increase HDL and to lower LDL in chicks, but does not always affect TC, whereas DFRB may increase all three serum lipid components.
米糠已被证明可降低仓鼠的血清胆固醇。给来亨鸡公鸡雏鸡喂食添加了0.5%胆固醇的60%全脂米糠（FFRB）和玉米/大豆（CS）日粮。两种日粮均含有18%的蛋白质。所有报告的参数均针对血清。在总胆固醇（TC）、甘油三酯（TG）、高密度和低密度脂蛋白胆固醇（HDL和LDL）方面发现了显著差异（p小于0.05）。在第二项研究中，给雏鸡喂食FFRB、脱脂米糠（DFRB）和CS日粮，这些日粮的蛋白质含量为18%、总膳食纤维含量为14.47%、脂质含量为10.78%，并添加了0.5%的胆固醇。喂食FFRB和CS日粮的雏鸡的TC和TG均显著较低（p小于0.05）。在所有日粮的HDL值方面发现了显著差异，FFRB的平均值最高（155毫克/分升），CS的平均值最低（114毫克/分升）。所有日粮在LDL方面均有显著差异（p小于0.05），FFRB、DFRB和CS的平均值分别为249、318和275毫克/分升。FFRB似乎可增加雏鸡的HDL并降低LDL，但并不总是影响TC，而DFRB可能会增加所有三种血清脂质成分。
