Effects of dietary β-cyclodextrin on plasma lipid and tissue cholesterol content in swine

초록

This study examined the effects of dietary P-cyclodextrin (PCD) on the cholesterol of blood and tissues of swine. Thirty six male castrated swine (Landrace x Yolkshire x Duroc) weighing 50 kg were randomly assigned to one of four dietary groups until their weight reached 110 kg. The groups were: basal diet without PCD (control) and basal diets containing 1.5%, 3.0%, or 5.0% PCD. Diets and water were offered ad libitum. No significant difference was found between treatments in terms of feeding performance measured by daily intake, daily weight gain, and feed efficiency. Addition of PCD to the diets significantly reduced total lipid, triglyceride and total cholesterol levels in swine blood, particularly in the group receiving 5.0% PCD, which showed decreases (p < 0.05) of 21.9%, 55.6% and 27.7%, respectively. Cholesterol levels in back fat, loin, belly and ham portions of swine fed PCD significantly differed (p < 0.05) from controls, especially in the 5.0% PCD-fed group, with reductions of 26.0%, 27.5%, 17.9% and 18.3%, respectively. These results suggested that the addition of PCD to the diet of swine could reduce their body cholesterol by decreasing the migration of cholesterol through the blood.
