The impact of incorporation of organic selenium into meat on growth performance, antioxidative status, and immune response in growing rabbits

| Abstract |
Thirty California male rabbits, 6 weeks old, were randomly divided into 3 experimental treatments (10 each). Animals were fed ad libitum the basal diet containing 0.13 ppm selenium (Se), supplemented with 0 (control), 0.15 or 0.3 ppm organic Se in the form of a yeast source from 6 to 12 weeks of age. Dietary supplementation of organic Se increased final body weight and daily gain, while feed conversion ratio was reduced in the growing rabbits. Supplementation with 0.15 and 0.3 ppm organic Se increased both hot carcass weight and dressing percentage. Se deposition in hindleg meat significantly increased in proportion to the dietary organic Se concentration. Dietary organic Se had no negative effects on chemical composition in hindleg meat. It is also interesting to note that inclusion of 0.15 or 0.3 ppm Se in the growing rabbits' diets elevated serum total antioxioxidant capacity and reduced the lipid peroxidation expressed as serum malondialdehyde which finally translated into enhancing the immune response. In conclusion, supplemental dietary organic Se enhanced growth performance and carcass weight, increased the Se content in meat, stabilized the antioxidative status, and elevated the humoral immune response in growing rabbits.
Key words: Organic Se, antioxidative systems, immunity.
