The effects of various Azolla levels in broiler feed on production and physiology were examined in this study. A total of 400 Ross broiler chicks were split into four identical groups for this reason (100 per each). Food and drink were ad libitum to all groups, but the groups that were treated (T1, T2, and T3), as called the control group, obtained varying percentages of Azolla (15 percent, 30 percent, and 45 percent), respectively. Weekly measurements of body weight and FCR (feed conversion ratio) were conducted, and samples of blood were taken at the conclusion of the experiment to assess the liver enzyme activity (GOT, GPT, and ALP), blood proteins (albumin and total protein), and lipid profile (triglyceride, cholesterol, VLDL, HDL, and LDL). With the exception of the activity of GOT, which was ultimately (p≤0.5) decreased, the findings revealed no alteration in the physiological parameters (liver enzyme activity, blood protein, and lipid profile) and an increase in body weight (p≤ 0.5) in the T3 (third group that was treated) in comparison to the control, where the FCR was decreased, at the same amount of feed (3 kg). To conclude, the addition of Azolla percentages (15, 30, and 45) to feed of broil improves both FCR and body weight without negatively impacting the broiler body's normal physiology. Moreover, it can save feed production expenses by over 30%.
