Three hundred and sixty sexed 3-day-old broiler chicks were divided randomly into six treatment groups (control, antibiotic and black cumin at four levels) of 60 birds each. Black cumin seeds at 0.5%, 1%, 2% or 3% and avilamycin at 10 mg/kgt were added to the basal diet and their effects determined on feed intake, daily live weight gain, feed conversion ratio and carcass characteristics. There were no significant differences in daily feed intake at 21 and 42 days (p>0.05). Average daily gain was significantly different between the treatments. The birds fed the diet containing 1% black cumin seeds and antibiotic were the highest average daily gain, followed by those the other treatment diets and negative control (p<0.05). From 1 to 42 days of age, feed conversion ratios were improved significantly by supplementation with 1% black cumin seeds and with antibiotic (p<0.05) by approximately 5% compared to the control group. Similarly, the highest cold carcass, thigh, breast, wing, neck and liver weights were observed in the 1% black cumin and antibiotic groups (p<0.05). Accordingly, 1% supplementation of black cumin seeds to diets could be considered as an alternative natural growth promoter for poultry instead of antibiotics.
Ciftci, M., Dalkilic, B., Cerci, I.H., Guler, T., Ertas, 0. N. and Arslan, 0.2009 ). Birds receiving the diet containing 500ppm cinnamon oil showed the highest average daily gain with best feed conversion efficiency. I n conclusion, cinnamon oil, at a dose of 500 ppm, could be used as an alternative to antibiotic for growth promotion in broiler diets.
To study the effects of dietary antibiotic (avilamycin) and cinnamon oil supplementation on broilers performance, 240 5-day-old commercial broiler chicks (Ross-308) were divided into 4 equal groups and randomly assigned to four treatment diets with four replicates. Experimental groups were; corn-soybean meal basal diet (Control), basal diet supplemented with 10 mglkg Avilamycin (Antibiotic), 500 or 1000 p p m of cinnamon oil (C500, ClOOO
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
