Using cinnamon (Cinnamomum zeylanicum) and turmeric (Curcuma longa L) powders as an antibiotic growth promoter substitutions in broiler chicken's diets.

ABSTRACT

In the current study supplementations of cinnamon (Cinnamomum zeylanicum) powder (CNP) and turmeric (Curcuma longa L) powder (TP) as an antibiotic growth promoter substitutions on growth performance, intestinal microbiota and hematological profile of broiler chickens have been investigated. A total of 240, one day old as-hatched broiler chickens (ROSS 308) were randomly assigned into five treatments with four replicates per treatment and 10 chickens per replicate. Treatment groups were C control (fed basal diet); CNP1 0.5% CNP; CNP2 1.0% CNP; TP1 0.5% TP; TP2 1.0% TP and 500 mg oxytetracycline (OTC)/kg of diet. Body weight gain (BWG), feed intake, and feed conversion ratio (FCR) were improved (p < 0.05) by CNP and TP while OTC improved BWG and FCR. Ileal and cecal Lactobacillus and total aerobes were significantly improved while coliforms and Escherichia coli were decreased by CNP, TP, and OTC. The percentage of packed cell volume (%PCV), hemoglobin (Hb), red blood cell (RBC) count, and white blood cell (WBC) count was increased by CNP and TP while OTC decreased %PCV, Hb, RBC, and increased WBC count. In conclusion, the results showed that OTC can be safely replaced by CNP and TP at 1.0% dose rate in broiler chicken's diets.
