Cholesterol Content in Eggs During the Laying Period

Abstract

The aim of this study was to determine the actual cholesterol content in the eggs of breeding hybrid Hisex Brown from a large scale poultry farm in dependence on the lay period. The eggs were collected during the whole lay period at 10-week intervals. The average content of cholesterol per egg increased from 153.45 12.39 to 263.90 14.83 mg. The lowest values (153.45 12.39 mg) were found in eggs at the beginning of the lay period (P < 0.01). Thereafter the cholesterol content was rising at 10 th (180.26 11.16 mg), 20 th (208.22 18.19 mg) and the 30 th (263.90 14.83 mg) week of the laying period. At the 30 th week of the lay it reached the peak. At the 40 th week (236.72 26.23 mg) we recorded a mild decrease (P < 0.05), followed by no changes till the end of lay.
