Influence of Feeding β-Cyclodextrin to Laying Hens on the Egg Production and Cholesterol Content of Egg Yolk
B. S. Park, H. K. Kang, A. Jang
Abstract
The main objective of the present study was to determine the effect of dietary 棺-cyclodextrin (棺-CD) on egg laying performance and cholesterol content of egg yolk. Feed intake, egg production and egg weight varied slightly, but not significantly, between hens fed either z control diet or a diet containing one of an increasing series of 棺-CD concentrations (2%, 4% or 6%). However, feed intake, egg production and egg weight were all lower in the hens fed on 8% 棺-CD (p<0.05). No difference in haugh unit values, egg yolk color and egg shell thickness were found between the different treatments. The cholesterol content of egg yolks (mg/g yolk) was significantly decreased by 0.71, 2.98, 4.00 and 4.24 mg in eggs from hens maintained on 2%, 4%, 6% and 8% 棺-CD, respectively (p<0.05). These observations indicate that appropriate supplementation of diets with 棺-CD can reduce the cholesterol content of eggyolks, thus raising the prospect of the production of a healthier functional food.
