The present experiment was conducted on 120 male broiler chicks which were divided into six groups of 20 each. Group 1 served as control, group 2 treated with imidacloprid @ 50 ppm in feed, group 3 was treated with spinosad @ 1000 ppm in feed, group 4 was treated with imidacloprid @ 50 ppm and spinosad @ 1000 ppm in feed, group 5 was treated with imidacloprid @ 50 ppm, spinosad @ 1000 ppm and Vitamin E @ 20 ppm in feed and group 6 was treated with imidacloprid @ 50 ppm, spinosad @ 1000 ppm and silymarin @ 1000 ppm in feed. The experiment was carried out for 4 weeks. | Effect of spinosad and imidacloprid on serum biochemical alterations in male broilers and its amelioration with vitamin E and silymarin
