ABSTRACT: The present study aimed to determine the effect of L-arginine (L-Arg) supplementation through drinking water on the productive performance, biochemical traits; antioxidant status of growing rabbit under summer conditions from June, Julie, Augustus and September, 2020. Sixty male Baladi red growing rabbits (weaned, 35 days), were randomly divided into four equal treatment groups with five replicate (3 rabbets each). All rabbits were fed same pelleted ration ad-libitum containing 18.8 % crude protein, 13 % crude fiber, 2680 kcal DE / kg diet. Each experimental group was supplied with drinking water from a separate container as follow (the water consumed was calculated by terrible times of feed consumed/day), the first group served as control (unsupplied), the second, third and Fourth groups supplemented with Arginine (L-Arg) in drinking water by levels 1, 2 and 3 g / L respectively, through the experimental period (35 90 days of age). The results indicated that the group supplemented with 2 g L-Arg/L of water had significantly improved body weight, body weight gain, performance index, growth rate % and feed conversion ratio at the end of experimental period (90 day of age). The relative weights of pre-slaughter weight and total edible parts were significantly increased for the groups supplied with 1 and 2 g of L-Arg/L compared to the other experimental groups. Triglyceride and high density lipoprotein concentrations for the group supplied the 2g L-Arg/L of drinking water recorded the significantly lowest values compared with the other groups and statistically equals with control group. Results of IgG, IgM, TAC and MDA for the group supplied with 2 g Arg/L were significantly improved compared to the other experimental groups.
