The present study has the title: “EFFECT OF THE ANNATTO FLOUR (Bixa orellana) ON PIGMENTATION TO THE CHANNEL AND IMMUNOGLOBULINS IN CHICKENS OF FATTENING” in which 200 cobb 500 line chickens were evaluated, of one day age, divided into four treatments and five repetitions with 10 birds per experimental unit. The formulation of diets was taken for each treatment: T0 = control, T1 = 0.1% Bixa orellana, T2 = 0.2% Bixa orellana and T3 = 0.3% Bixa orellana, making the inclusion of Annatto flour in the fattening stage. The study lasted 49 days. I used a completely randomized design with analysis of variance and Tukey test at 5% but for the variable pigmentation was used the statistical package SPSS statistics v23. The results obtained were: for the variable immunoglobulin M; T0, T1, T2 and T3 were statistically equal; for the variable immunoglobulin G; T1, T2 and T3 were statistically different with T0, this indicates an increase in the response of this immunoglobulin; finally, in the variable pigmentation was obtained that there are no statistical differences between treatments.
