Abstract An experiment on “Assessment of cinnamon (Cinnamomum cassia) powder as phytobiotic growth promoter in broilers†was conducted for a period of 42 days. Three hundred, day old commercial broiler chicks (Ven Cobb Strain) were used. The chicks were randomly divided into five groups that is control, negative control and three treatment groups with four replicates of fifteen chicks in each. The chicks were kept in floor pens; water and feed was provided ad-libitum throughout the experimental period. The control diet viz. standard broiler ration as per BIS (2007) standards (T0), which was supplemented with Oxytetracycline @ 0.1 g/kg of feed (T1), cinnamon powder @0.4 g/kg of feed (T2), cinnamon powder @0.8 g/kg of feed (T3) and cinnamon powder @1.2 g/kg of feed (T4). The CP (%) and ME (Kcal/kg) of Pre-starter, starter and finisher ration was 22.86 (CP) and 2996 (ME); 22.60 (CP) and 3090 (ME); 20.30 (CP) and 3189 (ME) respectively. The average weekly body weight gain (g) of experimental birds during 1st week was significantly higher (P<0.05) in control (T0) and T4 than T2; whereas, T1 & T3 groups ranged in between. At the end of sixth week the final body weight of birds were significantly higher in cinnamon treated groups than control group. The FCR of T2, T3 and T4 was significantly improved (P<0.05) during 5th and 6th week as compared to T1 whereas FCR in control group remained comparable. The percent dry matter digestibility of T2 was significantly higher as compared to control where as the coefficients for T1, T3 and T4 remained comparable. The PCV (%), TEC (×106/μl), TLC (×103/μl) and Hb (g/dl) were not affected (P>0.05) by cinnamon supplementation. The estimated serum biochemical parameters remained in normal physiological range for chicken in present study. It was observed that triglyceride (mg/dl) did not differ significantly (P>0.05) amongst treatment group. The total cholesterol (mg/dl) on day 35 of age was significantly lower in T4 as compared to T1; whereas total cholesterol content of T2, T3 and control (T0) ranged in between. The serum antibody titre against RD virus as observed on day 21st of study indicated that there was significantly higher immune response in control as compared to treatment groups. The erythrocyte LPO (nM MDA/ml) activity was significantly higher in T1 and T3 as compared with control. SOD (nM MDA/ml) activity in erythrocyte of experimental birds suggested significant increase (P<0.05) in SOD concentration in cinnamon supplemented group over the control. The catalase activity however did not differ significantly (P>0.05) amongst the treatment group. It was observed that the carcass traits including dressing %, edible meat % and giblet weight (g) did not differ significantly (P>0.05) amongst treatment groups. It was observed that the shelf life improved significantly (P<0.05) in cinnamon supplemented group as compared to control on 0 and 4th day. It was observed that the length of intestine (cm) with/without ingesta as well as thickness (mm) did not differ significantly (P>0.05) amongst the treatment group. However there was significant increase (P<0.05) in weight of intestine with/without ingesta (g) in T3 as compared to other treatment groups. The cost of feed per kg live weight remained almost comparable amongst the treatment groups. It is concluded that addition 0.12% of cinnamon powder in the diet could improve the overall performance and health of broilers.
