Effects of Dietary Ginger (Zingiber Ofjicinale), Cinnamon (Cinnamomum), Synbiotic and Antibiotic Supplementation on Performance of Broilers
Journal Title: Journal of Animal Science Advances - Year 2014, Vol 4, Issue 1
Abstract
This study was conducted to evaluate the comparative effects of ginger, cinnamon and synbiotic on performance, carcass characteristics, blood biochemical and hematological parameters of broilers. A total of 224 male one-day-old broiler chicks were assigned at random to 7 treatments with 4 replicates (8 chicks per replicate) in a randomized complete block design. Dietary treatments consisted of basal diet with no additives (control) or the basal diet supplemented with synbiotic (Biomin IMBO), antibiotic (virginiamycin), 0.4% ginger, 0.8% ginger, 0.4% cinnamon or 0.8% cinnamon. The results showed that all supplemented with feed additives decreased (P<0.05) feed intake and body weight gain, but improved (P<0.05) feed conversion ratio compared to the control group during the whole experimental period (1-42 d). The serum triglyceride level was decreased (P<0.05) by treatments 0.8% ginger, synbiotic and 0.8% cinnamon, which was significantly different from that of other groups. The lowest serum cholesterol levels (P<0.05) was also observed in the birds fed diets supplemented with 0.8% ginger and 0.8% cinnamon. Moreover, treatment 0.8% cinnamon statistically (P<0.05) decreased the serum low-density lipoprotein cholesterol level compared with the control diet. All diets increased (P<0.05) the values of RBC and hemoglobin, but decreased (P<0.05) abdominal fat pad compared to the control diet. The lymphocyte count in the birds fed diets supplemented with 0.4 and 0.8% ginger was also significantly (P<0.05) higher than the control group. However, dietary treatments had no significant effects (P>0.05) on the relative weights of spleen, bursa of Fabricius and thymus, and blood concentrations of glucose, total protein and low-density lipoprotein cholesterol level. In conclusion, this study showed that either 0.8 % ginger or 0.8% cinnamon could be suggested as effective alternative for virginiamycin with respect to the feed efficiency and health parameters.
