The present study aimed to evaluate the self-nanoemulsifying drug delivery system of cinnamon bark essential oil on growth and feed conversion ratio of broiler chickens. One hundred sixty broiler chickens were divided into four treatment groups. Each group comprised of five replicated pens and each replication contained eight broiler chickens. The treatments were control group CB0 (drinking water only), CB0.2 group (drinking water added with 0.2 ml/L SNEDDS CBO), CB0.4 group (drinking water added with 0.4 ml/L SNEDDS CBO), and CB0.8 (drinking water added with 0.8 ml/L SNEDDS CBO).
All of the SNEDDS CBO treatment groups reduced the amount of feed intake compared to the control group. However, the effect of the treatments did not affect the final body weight, weight gain, and feed conversion ratio of broiler chickens. The SNEDDS CBO treatment groups showed a trend to reduce the value of the feed conversion ratio of broiler chickens. Inclusion of SNEDDS CBO through drinking water at 0.2 – 0.8 ml/L can be an antibiotics alternative in poultry production by improving the efficiency of feed nutrients utilization.
