EFFECT OF HERBAL EXTRACT-SUPPLEMENTED FEEDS ON OXIDATIVE STRESS, BIOCHEMICAL MARKERS AND PRODUCTION PERFORMANCE IN JABALPUR COLOUR LAYER BIRDS

摘要

The present study was aimed to evaluate the impact of ginger, cinnamon bark, chicory and stevia extract-supplemented feeds on serum clinical biochemistry and production performance in Jabalpur colour birds. Fifty four birds of 32 weeks age were randomly divided into 9 groups of 6 birds each. Control group was fed normal basal feed whereas rest groups were fed on feeds supplemented with alcoholic extracts of various herbs separately at 2 levels each [ginger, cinnamon and stevia extract mixed with feed@ 2.5 and 5.0 g kg~(-1) feed and chicory extract @ 1.25 and 2.5 g kg"' feed]. Blood samples, collected on 0, 14, 28, 42 and 56th day of treatment, revealed a non-significant decrease in lipid peroxidase and non-significant increase in superoxide dismutase activity in birds of treatment groups. Reduced glutathione showed significant increase in all the treatment groups with higher value in birds fed with chicory (2.5 g kg~(-1)) and cinnamon (5 g kg~(-1)) supplemented feed, respectively. Glucose-6-phosphate dehydrogenase showed significant increase from days 0 to 56 in all the treatment groups. Alanine aminotransferase and aspartate aminotransferase showed a decreasing trend and significant lowering effect was noticed in birds fed with chicory and ginger. The serum creatinine showed significantly low value in chicory (2.5 g kg~(-1)) fed birds. No significant variation was observed in blood urea nitrogen. Increase in egg weight was significant higher in treatment groups with highest increase in ginger @5 g kg~(-1) fed birds. The supplementation of herbal drugs increased body weight significantly as the interval of time increased up to 56th days with highest weight in birds fed with chicory @ 2.5 g kg~(-1) feed.
