Abstract

This experiment was conducted to evaluate the safety of high-dose phytosterol supplementation for laying hens by determining performance, egg quality and lipid metabolism. Three hundred and sixty 21-week-old Hy-Line Brown laying hens with similar body weight and laying rate were randomly assigned to 5 groups with 6 replicates of 12 birds each. Birds were fed basal diets supplemented with 0 (control), 20, 80 (the maximum recommended valid dose, MRAD), 400 (five folds of MRAD) and 800 mg/kg (ten folds of MRAD) phytosterol for 12 weeks, respectively. All birds were acclimated to the basal diet for 3 weeks. The results showed as follows: dietary phytosterol had no significant effects on laying rate, feed intake, egg mass and the ratio of feed to egg (P>0.05). Only egg yolk, albumen and eggshell percentages were significantly affected by dietary phytosterol in the end of this experiment (week 12) (P0.05). It is indicated that there is no adverse effect on laying performance, egg quality and cholesterol content except for yolk cholesterol content of high-dose phytosterol.
