the effect of lavender essential oil (leo) on broiler performance, carcass characteristics and blood metabolites was examined in a completely randomized design with 5 treatments (control diet, virginiamycin 10% (50 ppm) and 3 diets containing 150, 250, 350 ppm lavender essential oil) and 5 replications in a period of 42-days. no significant differences were noticed for feed intake between the t...
This study was conducted to evaluate the effects of algal fucoidan and probiotic Bacillus subtilison growth performance, blood metabolites and intestinal morphology in broiler chickens. A total of 250 one-day-old Ross 360 male broiler chickens were randomly distributed into 5 treatments (6 replication pens/treatment) and reared for 42 d. The 5 dietary treatments were as follow: 1) a corn-soybea...
