Effect of herbal extract supplementations in feed on serum and eggyolk lipid profile in Jabalpur colour layer birds

The present study was conducted to assess the effects of ginger, cinnamon, chicory and stevia extract-supplemented feeds on lipid profile in serum and egg yolk of Jabalpur colour birds. Fifty four Jabalpur colour birds of 32 weeks age were randomly divided into 9 groups of 6 birds each. One group (control) was fed normal basal feed whereas rest groups were fed on feeds supplemented with alcoholic extracts of various herbs, separately, at two 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⁻¹ feed]. Blood samples were collected on 0, 14^th, 28^th, 42^nd and 56^th day and serum analyzed for changes in various biochemical parameters. The serum lipid profile showed a decreasing trend on herbal supplementation as compared to control. The total lipid was low in birds fed chicory (2.5 g kg⁻¹ feed) and cinnamon (5 g kg⁻¹ feed) followed by ginger (5 g kg⁻¹ feed) and cinnamon (2.5 g kg⁻¹ feed). The serum cholesterol and triglycerides showed more decrease in cinnamon (5 g kg⁻¹ feed) and chicory (2.5 g kg⁻¹ feed) fed birds than other groups. The increase in mean HDL concentration was significant in birds fed cinnamon (2.5 g kg⁻¹ feed), and stevia (5 g kg⁻¹ feed) on 56^th day. Low LDL and VLDL were observed in birds fed cinnamon (5 g kg⁻¹ feed). The lowest concentration of egg yolk lipid and egg yolk cholesterol was noticed on 56^th day in birds fed cinnamon (5 g kg⁻¹ feed), however least egg yolk triglyceride was low in chicory (2.5 g kg⁻¹ feed) and cinnamon (5 g kg⁻¹ feed) fed birds.
