A Study on the Effect of Cinnamon Powder in Diet on Serum Glucose Level in Broiler Chicks

Chickens have a blood glucose level that is twice as high as that of most mammals and are resistant against hypoglycemia. This study was conducted to investigate the effect of Cinnamon powder (CP) in broiler diet on serum glucose level. Different levels of CP were added to a standard diet to determine its effects on serum glucose level. There were five treatments: a negative control diet without the additive (Tj), 250 mg/kg (T2), 500 mg/kg (T3), 1000 mg/kg (T4) and 2000 mg/kg (T5) CP in diet. A total of 320 one-day-old mixed-sex broilers (of the breed Ross 308) were distributed into 16 pens with 20 chickens in each one, comprising 3 replicates per treatment (except for Tb which had 4 replicates). We conducted the experiment in an unbalanced completely randomized design. The diets were prepared freshly each day. Broiler chickens were grown under standard conditions from 1 to 4 days of age and then CP was added to their diet from 4 to 7 days of age. On day 7, two chickens from each replicate pen were selected randomly and their medial metatarsal vein blood sample was obtained. The results of this experiment indicated that there is no statistically significant difference among treatments.
