Abstract
The research was conducted to study the effect of cinnamon powder supplementation on growth
performance and antioxidant enzyme activities in broiler chicken. A total number of one hundred and
sixty, day old broiler chickens were randomly divided into four treatment groups. Each treatment was
further subdivided into four replicates with ten birds in each replicate. Treatments included T1: basal
diet without antibiotic, T2: basal diet with antibiotic, T3: basal diet with 0.5% cinnamon powder and T4:
basal diet with 1% cinnamon powder. The experimental diets were fed for 6 weeks of duration and feed
intake, body weight was recorded phase-wise. At the end of experiment, a five days duration metabolic
trial was conducted to determine the nutrient metabolizability and one bird from each replicate was
slaughtered, dressed and then used for carcass parameters, microbial count and gut morphometry birds.
The results showed that average feed intake was significantly (p<0.05) higher in T4 (group
supplemented with 1% cinnamon powder) followed by T3 (group supplemented with 0.5% cinnamon),
T2 (group having basal diet with antibiotic) and lowest in T1 group. Similar trend was observed in
average body weight, average body weight gain, dry matter metabolizability, nitrogen retention and
gross energy metabolizability. Significantly (p<0.05) better FCR was observed in cinnamon powder
supplemented groups in comparison to un-supplemented groups. Marked increased in carcass traits
were observed in case of cinnamon inclusion in diet at 1% level. Blood parameters (Hb and TEC ) were
significantly improved while heterophils were significantly decreased in 1% cinnamon supplemented
groups in comparison to T1 group whereas no difference were observed in TLC count. Significant
(p<0.05) reduction in triglycerides, total cholesterol and LDL were observed in groups supplemented
with cinnamon powder in comparison to control group. Significantly (p<0.05) higher lactobacilli count
and lower E.coli count were noticed at 1% cinnamon inclusion in the diet. In gut morphometry,
significantly (p<0.05) higher villi height was found in cinnamon supplemented group at 1% level.
Activity of antioxidant enzymes (SOD and catalase) were significantly (p<0.05) higher in treatment
group supplemented with 1% cinnamon powder. Highest profit (Rs. 59.33) was observed group
supplemented with 0.5% cinnamon powder (T3) and lowest (Rs. 55.24) was in group fed basal diet
without antibiotic (T1). Thus, it was concluded that addition of cinnamon powder at 1% level in the
diet of broilers had significant effect on growth performance, nutrient utilization, carcass traits, blood
parameters, serum parameters, gut morphology and antioxidant enzymes activity of birds.
