Effect of cholesterol and fat supplemented diets on cholesterol contents of follicular fluid and egg yolk of quails of three age groups

Abstract

Effect of feeding cholesterol and fat supplemented diets was studied on cholesterol contents of follicular yolk and egg yolk of quails of 3 different age groups i.e. 5-week-old, 12-week-old and 1-year-old. Five different dietary combinations were fed to different groups for 30 days. The diets were : control diet, normal diet without fish-meal, control diet with 1% cholesteral, control diet with 10% lard, and control diet with 1% cholesterol and 10% lard. Different dietary treatments affected both the follicular and egg yolk cholesterol levels in all the treated birds. The cholesterol levels were higher in i-year-old birds irrespective of the dietary treatments. The dietary treatment affected the cholesterol level of F1 follicular yolk of 12-week-old the least as compared to 5-weeks old or 1-yearold laying quails.
