| The study was conducted to investigate the effects of the grape seed-, olive leaf- and pomegranate peel-extract supplementation to diets on performance, serum lipid profile and ileum bacteria content of broilers at 42 d of age. The diets were as follows: a basal diet (CONT) which contained no feed additive, a diet supplemented with either a probiotic (Protexin™) (P), oleuropein (as olive leaf extract) (OLE100 and OLE200), proanthocyanidin (as grape seed extract) (GSE100 and GSE200) and proanthocyanidin (as pomegranate peel extract) (PPE100 and PPE200) at two levels of 100 and 200 mg/kg. The OLE100, OLE200, PPE100 and PPE200 diets increased BWG and improved FCR of broilers during the period of 0 to 6 weeks compared to the CONT, GSE100 and GSE200 diets. Feeding especially the PPE100 and PPE200 diets increased serum HDL cholesterol level compared to the other (except OLE100 and OLE200) diets. Serum LDL cholesterol level was decreased by especially the PPE200, PPE100 and OLE200 diets compared to the other dietary treatments. Morever, all dietary treatments significantly decreased serum triglyceride level compared to that of broilers fed on the CONT diet. The hot and cold carcass yields of broilers were increased by the experimental treatments (except GSE 100 and GSE200) compared to the CONT diet. Especially the PPE100, PPE200, OLE100, OLE200 and P diets were more effective in reducing the concentrations of total coliform bacteria and E. coli compared to the CONT and GSE100 diets. The P, OLE100, OLE200, PPE100 and PPE200 diets increased the concentration of Lactobacillus bacteria in the ileal digesta compared to those of broilers fed on the CONT, GSE100 and GSE200 diets. In conclusion, oleuropein in OLE and proanthocyanidin in PPE in maize-soybean meal based diets positively modified the growth performance, serum lipid concentration and ileum microflora content of broilers and can be used as natural antimicrobials in broiler diets instead of probiotics. |
