abstract = {This study was intended to assess effects of dietary vitamin
C supplementation on growth performance, meat quality, immune function as well
as anti-oxidative capacity of broilers. A total of 240, 1 day old Avian broiler
chicks divided randomly into three treatments, each of which was composed of
eight replicates with ten birds and birds fed a corn-soybean meal basal diet
supplemented with 0, 150, 300 mg kg-1 vitamin C, respectively. Results
showed that dietary vitamin C addition could significantly increased average
daily weight gain and feed intake of the broilers (p<0.05) but did not have
significant effects on their feed to gain ratio; compared with the control treatment,
dietary vitamin C addition at 300 mg kg-1 could significantly increased
the pectoral muscle percentages, abdominal fat percentages and liver weight
ratio of broilers (p<0.05). Dietary vitamin C additions could significantly
increase pectoral muscle b* and leg muscle L* of the broilers and that significantly
improved the water holding capacity and tenderness of their leg muscles (p<0.05).
The thymus index, bursa of Fabricius index, Newcastle disease antibody level
of broilers were much higher where vitamin C was added at 300 mg kg-1
than in the control treatment indicating that immunity of broilers got effectively
improved (p<0.05). Dietary vitamin C addition at 300 mg kg-1 significantly
increased the vitamin C content in blood serum and pectoral muscles (p<0.05),
also superoxide dismutase and glutathione peroxidase activities and total anti-oxidative
capacity in blood serum significantly increased (p<0.05), so that dietary
vitamin C addition was helpful to eliminating free radicals and raising anti-oxidative
capacities of broilers. Dietary vitamin C addition at 300 mg kg-1
significantly slowed down lipid per-oxidation and color variation of pectoral
muscles while the muscles were refrigerated at 4°C, so that it took effect
along with anti-oxidative enzymes to inhibit oxidation-caused meat quality deterioration,
stabilize meat colors and prolong meat shelf life. Results of the present study
indicated that dietary vitamin C addition at 150 mg kg-1 performed
better in improving growth performances and immune functions of broilers and
dietary vitamin C addition at 300 mg kg-1 performed better in improving
body and muscle anti-oxidative capacity, reducing lipid per-oxidation in meat
storage and prolonging meat shelf life.}
