An experiment was conducted to investigate the response of commercial enzymes supplementation at different dietary fiber levels on the egg laying performance and egg cholesterol contents. Three hundred and twenty laying birds of 22 weeks age were randomly distributed in 16 groups. Eight diets containing 8,9,10 and 11 percent crude fiber without and with commercial enzyme were formulated. Each diet was offered to a duplicate group of birds. Supplementation of enzyme at 8 and 9 percent crude fiber levels significantly (P≤0.05) increased the egg production and feed consumption, but at higher dietary crude fiber levels, enzyme supplementation reduced the percent egg production. Increase in crude fiber level irrespective of enzyme supplementation from 8 to 10 percent increased the egg production non significantly. The total cholesterol per egg reduced by supplementing the enzyme at all dietary fiber levels except at 9 percent. On per g yolk basis the cholesterol was significantly (P≤0.05) affected by the dietary treatments. The data indicated that supplementation of enzyme at 10 and 11 percent dietary crude fiber decreased the cholesterol per g of yolk. It was concluded that supplementation of enzyme irrespective of dietary crude fiber level decreased the total cholesterol level and the cholesterol per g of egg yolk.
