Abstract
The present study was planned to investigate the extent of the protective effect of cinnamon against the possible damage effect of thermally oxidized palm oil on broiler chicks. A total number of 150 one d-old Cobb 500 broiler chicks were randomly divided into three treatment groups. The first group was served as control and fed the basal diet with tap water. While the 2ndgroup fed the basal diet supplemented with 2g cinnamon/kg diet, the 3rd group fed the basal diet supplemented with 5% thermally oxidized palm oil in combination with 2g cinnamon/kg diet. The experiment has lasted till chicks were 42 d old. Bodyweight, feed consumption, feed conversion ratio was estimated. Estimation of the effect of different treatments on the PPAR-α gene expression, Estimation of the lipid profile in serum, Estimation of the cholesterol level in the liver tissue. Correlation between the cholesterol level in both serum and liver tissue and determination of oxidative stress markers in serum. The results showed that the addition of cinnamon increases body weight and feed consumption plus improving the feed conversion ratio. Cinnamon also causes a significant increase in the PPAR-α gene expression in liver tissue, decreases the cholesterol concentrations in serum and liver, decreases triglycerides in serum and decreases the oxidative stress markers.
Highlights
Poultry production is a business which like any other business seeks to generate profit, one of the objectives of any poultry producer is to keep the balance between a cheap diet with the least coast and obtain maximum productivity (Ahiwe, et al, 2018)

Lipids help in Supplying fat-soluble vitamins and essential fatty acids, reduce dust in the facilities, attenuating growth reduction in heat stress conditions, improve the pellet quality, and improve the diet palatability (Pettigrew, and Moser, 1991)
Summary
Poultry production is a business which like any other business seeks to generate profit, one of the objectives of any poultry producer is to keep the balance between a cheap diet with the least coast and obtain maximum productivity (Ahiwe, et al, 2018). Cinnamon is one of the phytogenic feed additives which are plant-derived products used in animal feeding in order to improve livestock performance. Lipids help in Supplying fat-soluble vitamins and essential fatty acids, reduce dust in the facilities, attenuating growth reduction in heat stress conditions, improve the pellet quality, and improve the diet palatability (Pettigrew, and Moser, 1991). For cost-saving, heated fats are used for up to 1 week before it is discarded and replaced with a fresh one These fats have high concentrations of lipid peroxides (Sülzle, et al, 2004). The concentrations of various lipid peroxidation products in heated fats depend on their thermal treatment. Oxidative stress constitutes an important factor of biological damage and is regarded as the cause of several pathological conditions that affect poultry growth and development (Avanzo, et al, 2001; Iqbal, et al., 2002). (Sahin, et al, 2003; Panda, et al., 2008), and 3) pathological conditions (ascites, fatty liver hemorrhagic disease syndrome, arthritis, coccidiosis) (Papas, 1999; Iqbal, et al., 2002)
