    The study was carried out at the Rio de Oro site belonging to the Andrés de Vera parish of the Portoviejo canton, located on the blanket road Km 7 ½; in a 7m long and 5m wide and 3m high shed, the antiadipogenic and hypoglycemic activity of a purple corn extract (PCE) -100 mg / kg of food- and of different levels of flaxseed oil (Ali ) (0%, 2% and 4%), replacing palm oil, using 180 COBB 500 chickens, 28 days old, fed ad libitum with isocaloric and isoproteic balancing, and distributed randomly in the following treatments: control treatment (TC; 0 mg EMM and 0% ALi); treatment 1 (T1; 0 mg EMM, 2% ALi); treatment 2 (T2; 0 mg EMM, 4% ALi); treatment 3 (T3; 100 mg EMM, 0% ALi); treatment 4 (T4; 100mg EMM, 2% ALi); treatment 5 (T5; 100 mg EMM, 4% ALi); each treatment consisted of 5 repetitions of 6 chickens each; at 56 days of age, the productive performance of the birds was assessed, final live weight, weight and yield to the carcass, relative weight of the liver, heart and fat; Spectofometry was performed to evaluate the lipid profile: total cholesterol, triglycerides, LDL and HDL, the HDL / LDL ratio and glycemia; for histopathological analyzes, liver samples were obtained; The results were processed using ANOVA, Completely Random Design (DCA) with 3x2 factorial arrangement, the differences between means were calculated using the Tukey test (p <0.05). The highest final weight was recorded in T5 (3283 ± 424.1); No significant differences were observed for carcass weight and performance, relative weight of liver, heart and abdominal fat; The HDL / LDL ratio was better at T 3 and 4 compared to the control group, while glucose, total cholesterol, triglyceride levels did not differ between treatments. These results suggest that the intake of EMM and Flaxseed Oil could exert an atheroprotective effect, favoring the weight of the birds, respectively, without modifying other productive and biochemical parameters.
