Abstract
A study was carried out in broilers from day-old to 6 weeks of age to
evaluate the effect of different levels of amla and vitamin C supplementation
in corn-soya based diet (control group) on growth performance, plasma
antioxidant status, corticosterone and glucose, serum total cholesterol,
triglycerides, high density lipoproteins and thyroxine.
Amla contained high amount of vitamin C (729.56 mg/100g in fresh
pulp and 333.38 mg/100g in dried pulp). The addition of different levels of
amla and vitamin C did not improve body weight but amla at 1 per cent level
in feed reduced the feed consumption with better feed efficiency.
Feeding of amla and vitamin C at various levels, did not produce any
significant difference in plasma levels of glutathione peroxidase, reduced
glutathione, superoxide dismutase whereas plasma malonaldehyde level was
significantly reduced in the supplemented groups.
The mean plasma corticosterone level was reduced after adreno
corticotrophin injection. Plasma glucose, serum total cholesterol, serum high
density lipoproteins, serum thyroxine level were not influenced by
supplementing amla and vitamin C. Serum triglycerides was significantly
(P<0.01) reduced in the treatment groups compared to control.
It is concluded that supplementation of amla upto 2 per cent of diet and
vitamin C did not improve body weight and feed efficiency but improved
anti-oxidant status in broilers.
