Abstract EN

This study was conducted at the poultry from Department of Animal science College of Agriculture / University of AlQasim Green , for the period from 17/10/2014 to 29 /11 /2014.

Followed by labortorial work.The research aims to study the best lycopene concentration that added to the diet deeras heat strees for quail 300 unsexed quail chicks were used and reaved on litter from 1-8 days of age and then moved to batteries.

Lycopene was added to chicks diet from 8 - 42 days of age.

Chicks were randomly distributed in to 5 treatments T1, T2, T3, T4 and T5 and lycopene levels added to the diets were 0, 150, 200¸ 250 and 300 mg lycopene / kg feed respectively .the results of the experiment showed significantly increase (p ˂ 0.01) in weights and carcass ration for lycopene tratments in comparison with control, Highly significant (P˂0.01) increase for lycopene tratments in liver weight, as well as a significant improvement (P˂0.05) in heart weight and gizzard during the duration of the experiment, as well as high moral (p ˂ 0.05) in the preparation of bacteria (Lactobaclli) while¸what a significant decrease (p <0.01) was happened in bacteria (Colifrom).

This study concluded that lycopene addition to the diets of quail works to increase the percentage of carcass and the percentage of some edible internal organs
