AB  - The objective of this experiment was to determine the effect of fat type on hen performance, cholesterol level and some egg charecteristics. A total number of 75 Lohman white layers, with 36 week old weeks of age at the beginning of the experiment, was distributed in a completely randomized experimental desing into five treatments, with three replicates of 5 hens each. Fat type had no significant (p>0.05) effect on Final Body Weight (FBW), Feed Intake (FI) and Feed Conversion Ratio (FCR) of laying hens. The FBW of laying hens at the end of experiment ranged from 1586.67±21.53-1623.33±27.21 g. The FI and FCR of laying hens ranged from 124.48±0.29-126.66±0.11 and 2.14±0.02-2.28±0.04, respectively. The fat type also had no significant (p>0.05) effect on the external egg charecteristics. The egg weigth and shell weight ranged from 60.07-63.55 and 7.62-7.96 g, respectively. The egg shape index ranged from 74.00-75.00%. The fat type had significant (p<0.001) effect on the cholesterol level of egg of laying hens. The egg yolk cholesterol level and egg yolk fat content ranged from 211.89-248 mg and 32.87-36.02 g, respectively. Egg yolk cholesterol level and fat content of laying hen fed diet V was significantly (p<0.001) higher than those of laying hen fed other diets. It is likely to manipulate the chlosterol level of egg without changing external and internal egg quality charecteristics.
