ABSTRACT
Arginine (AR) plays an important role in physiological functions, antioxidant status, mitigation of heat stress, and improving performance in birds. This study aimed to evaluate the effect of dietary L-arginine on hematology, protein and lipid profiles, renal, hepatic, and intestinal functions, antioxidant status, and immunity of heat stressed Egyptian geese. A total of 30 sexually mature ganders (local Egyptian male geese strain) with 10 months of age and 3.20±0.25 kg body weight was divided into three groups (10 birds/group). Ganders were kept under normal hot climate in summer of Egypt and fed ad libitum on a commercial mash diet (15.2% CP and ME of 2690 Kcal/kg). The control group (G1) was fed on a basal diet, while G2 and G3 were fed the basal diet with 0.2 and 0.4 g AR/kg, respectively. At the end of an experimental period of three months, five ganders were slaughtered for blood collection and histological study. Hematological and plasma biochemical parameters, liver and kidney function, and antioxidant markers were determined. Results showed that RBCs and lymphocyte increased, while neutrophils and Neut./Lymph ratio decreased in G2, however, Hb, PCV, RBCs, MCH, and lymphocyte increased, while WBCs, neutrophils, and Neut./Lymph ratio decreased in G3 in comparison with G1. Plasma total protein and albumin increased, while total cholesterol, triglycerides, LDL, urea, creatinine, AST, and ALT decreased in G2 and G3 compared with G1. The impaired effects of heat stress on liver and intestine were restored in G3. Plasma total antioxidant capacity, activity of SOD and catalase, and IgG and IgM increased, while malondialdehyde and cortisol decreased in G2 and G3 compared with G1. In conclusion, dietary supplementation of L-arginine (0.4 g/kg) for three months improved hematology, protein metabolism, lipid profile, liver, kidney, and intestine functions, antioxidant status, immunity and welfare of Egyptian geese under heat stress condition.
