The present study aimed to evaluate the effect of dietary supplementation with different levels of L - arginine ( L - Arg ) above the levels recommended by NRC (1994) on egg production, reproduction performance , egg quality and some physiological and immunological parameters . The experimental period started when the hen s were 40 week old , and ended to three months. Two local strains Fayoumi ( Fa ) and Golden Montazah ( GM ) were used with a total number of 180 laying hens and 18 males (90 females and 9 males from each strain). Selected male and female of each strain were divided randomly into 3 groups /strain , each group consisted of 3 replicates (10 female and 1 male /replicate). Control diet (contain recommended level of L - Arg 0.700% L - Arg ). Crystalline amino acid ( L - Arg ) was supplemented by 2% and 4% as a percentage of dietary L - Arg to achieve 0.714% L - Arg and 0.728% L - Arg respectively (treatment groups ) . During the experimental period thirty six cockerels (18 from each strain) were housed in individual cage; each 6 cockerels fed one of the experimental diets to determine semen quality. During the experimental period, feed consumption and egg number were recorded daily . Eggs were weighed daily and egg mass per hen per day were calculated. Feed conversion ratio and c rude protein conversion were calculated . During the last month of the experiment three hatches were conducted weekly to determine hatchability parameters . At the end of the experiment random samples of eggs representing controls and treatments (10 eggs /replicate) for each strain examined for egg quality parameters . Two blood samples were collected from each replicate within each strain in all groups to estimate physiological and immunological parameter . Experimental results showed that: Arginine supplementation above NRC caused significant increase in egg production percent and egg mass during the whole experimental period. There was at least 6% of extra eg g production over the control. Feed conversion ratio and crude protein conversion improved significantly, as the dietary L - Arg level increased. Most incubation and semen parameters improved and female ratio decreased significantly by L - Arg supplementation. Arginine supplementation had no adverse effect on physiological parameters. Arginine supplementation was associated with a reduction in heterophilus percent and heterophilus/lymphocytes ratio and was associated with increase in white blood cells count and lymphocytes percent . On the other hand egg quality was not affected significantly by any of the dietary L - Arg levels.
