Effect of adding different levels of Lycopene to the ration on some lipid profile traits of the Laying hens ISA-Brown*

Abstract

This research was conducted to study the effect of adding different levels of Lycopene powder to the ration on some lipid profile traits of laying hens ISA-Brown. Used in this experiment 345 layer hens ISA Brown and were 23 week old were randomly  allotted  in 5 groups , 3 replicates ( 23 hens per replicate) For the period  from 7/1/2013 to 23/6/2013  . Experiment included five treatments and by the following :First treatment : a negative control group without of any addition , treatment second group control positive was added 200 mg / kg feed (vitamin E) to the ration , and treatments, third, fourth and fifth represents add lycopene powder  into the ration at rates 100, 150 and 200 mg / kg feed respectively . Included experiment estimate some lipid profile traits (cholesterol , cholesterol egg yolk ,  triglycerides , high density lipoprotein (HDL) and low density lipoprotein (LDL) The results of the experiment get decline of improvement (p <0.05) to the level of cholesterol, cholesterol egg yolk , triglycerides and low density lipoprotein (LDL) when compared with first treatment (control) , and increased to the level of  high density lipoprotein (HDL) in the blood serum laying hens for treatments lycopene powder and vitamin E treatment during the periods experiment .

Key word : Lycopene , HDL , LDL , cholesterol egg yolk .
