Abstract EN

The aim of this study was to identify the effect of supplementation of Methionine and Lysine on productive performance and some Physiological parameters of quail reared under high temperature.

Two hundred forty unsexed one day old bird were used in this study .

Birds were reared into cages located inside semi opened house.

All suitable environment were available until marketing age 42 days.

Four treatments in each 3 replicates (20 birds in each) were used as follows : T1 (control), T2 standard ration supplemented Methionine with 450 mg/kg ration, T3 standard ration supplemented Lysine with 600 mg/kg ration and T4 standard ration supplemented with 450 mg Methionine and 600 mg Lysine /kg ration.

Feed and water ad Libitum.

Statistical analysis of data showed significant increase (P≤0.05) in live body weight and weight gain for T4 and significant increase in Hemoglobin concentration for T2.

no significant difference in feed consumption , feed conversion ratio , Percentage of edable organ , heart , liver , gizzard , glucose , Triglycerides , Total protein , albumin , globulin , globulin/albumin in blood plasma.

and dressing percentage.
