This study demonstrates that pork cholesterol levels are reduced in fattening stage swine fed β-cyclodextrin (βCD). The study subjects were 120 swine fed their respective chow diets containing 0, 5, 7, or 10% βCD for 35 consecutive days. Plasma total lipids, triglyceride and total cholesterol of the βCD-treated group were significantly lower than those of the control group (p＜0.05). The levels of plasma lipid were significantly decreased by 63.22 mg, 73.98 mg, and 82.12 mg in the fattening swine group fed βCD at 5%, 7%, and 10%, respectively, compared to those in the control group (p＜0.05). When 5, 7, and 10% βCD was administered to fattening swine, the triacylglyceride levels were decreased by 56.24 ㎎, 55.48 ㎎, and 60.02 ㎎, and total cholesterol concentration was reduced by 25.05 ㎎, 27.17 ㎎, and 30.19 ㎎, respectively, compared to those in the control group (p＜0.05). Excretion of total steroid significantly (p＜0.05) increased with the increasing amount of βCD supplementation. The cholesterol levels of swine back fat, belly, loin, and ham were significantly decreased with increasing βCD supplementation (p＜0.05). The pork cholesterol was significantly (p＜0.05) reduced by 15.31% in the βCD-treated group, compared to that of the control group. These results suggest that feeding βCD to fattening swine may produce novel functional pork with low cholesterol levels.
