Abstract

Effect of dietary zinc-methionine (Zn-Me), on growth performance, carcass characteristics, anti-oxidant status, immunity, liver and kidney functions of NZW growing rabbits was studied. Total of 80 rabbits were assigned into 4 groups fed basal diet with 0 (G1), 50 (G2), 100 (G3) and 150 (G4) mg of Zn-Me/kg diet, respectively. The average of body weight, weight gain, daily feed intake and feed conversion, performance index and viability rate were recorded at age intervals from 5 to 13 wk. The carcass characteristics, hematological and biochemicals, anti-oxidant and Immunoglobulins in serum were determined at the termination of the experimental period (13 wk). Results revealed that Zn-Me (100mg/kg diet) addition increased (P<0.05) growth performance (body weight of rabbits at 9 and 13 wk of age, and daily gain of rabbits at 5~13 wk of age interval), hemoglobin, red blood cells, platelets and hematocrit, and neutrophils and eosinophils, serum total proteins, glucose, total anti-oxidant capacity, glutathione reduced ,glutathione S-transferase and superoxide dismutase, and immunoglobulins concentrations. The count of blood cells and lymphocytes, monocytes and acidophils percentages, and triglycerides, creatinine, urea concentrations, and enzyme activity and thiobarbituric acid-reactive substances concentration decreased (P<0.05) as affected by Zn-Me (100mg/kg diet).  The carcass net weight, dressing percentages (based on carcass net carcass weight or plus edible organs), and spleen and heart weight percentages were (P<0.05) the highest in G3 compared with other groups. In conclusion, dietary supplementation with zinc-methionine (100 mg/kg diet) can improve growth performance, lipid profile, immunity and anti-oxidant status, without adversely effects on kidney and liver functions of growing rabbits.
