--- Use of annato extract as a natural antioxidant was evaluated upon productive efficiency in comparison with use vitamin E in 360 male broiler chickens Ross 308, this birds were randomly assigned into three different treatments who were tested in 3 trials for each treatment with 40 Ross broiler chickens. T1 was the control group and it used a diet based on 100% of vitamin E (10 mg / kg bw), T2 used a diet made with 50% extraction annatto (150 ppm) and 50% of vitamin E (10 mg / kg bw ), T3 was a diet with 100% annatto extract (200 ppm). The data recording was taken from the first to the sixth week of breeding and the parameters evaluated were average body weight, cumulative weight gain, cumulative feed consumption, feed conversion, total mortality and IEPE. At the sixth week of breeding the T3 (2877.7g) obtained an average body weight higher than T1(2867.3g) and T2(2859g). The cumulative weight gain of T3 (2822.91g) was higher than T1 (2811.84g) and T2 (2803.58). The cumulative food consumption T3 (3899.46g) was higher than T1 (3892.51g) and T2 (3908.02). The feed conversion showed no difference between treatments. The percentage of total mortality for the three treatments (2.5%) was lower than the standard. The T3 EPEF obtained a slightly better production efficiency (492.98) than T1 (490.32) and T2 (485.54). According to statistical analysis no significant difference (p <0.05) was found between the three treatments for any of the parameters evaluated. With these results we can conclude that the annatto extract can efficiently replace vitamin E into the diet of birds. Keywords: diet, Vitamin E, annatto extract, natural antioxidant
