Efecto de la harina de achiote (BIXA ORELLANA) sobre el desempeño productivo de pollo de engorde.

Abstract

The objective of this research was to evaluate the effect of the inclusion of annatto flour (Bixa orellana) on the productive and economic performance of broilers. A total of 96 birds of the Cobb 500 line were used divided into four treatments, each one with three replicates made up of eight animals: Treatment 1 comprised 2%, treatment 2 4% and treatment 3 6% of flour achiote in your daily ration. The productive parameters of: feed consumption, weekly weight gain (GPS), feed conversion (CA), feed efficiency (EA), European efficiency factor (FEEP), productivity index (IP) were evaluated and at the end the determination of pigmentation in meat and carcass yield (RC). The data obtained were subjected to analysis of variance with a significance of 5%. The linear and quadratic effects were evaluated using octagonal contrasts. There was a statistical difference (P≤0.05) in the CR and pigmentation parameters between the treatments and the control. A positive linear order effect was evidenced for pigmentation, with T3 presenting the best average with 6.66. For CR, a negative linear order effect was observed. For the other parameters, similar behavior was observed between the control and the treatments that included B. orellana flour in their composition. In the economic analysis, T1 presented the best values for feed cost per kg of meat produced with $ 3,756.97 and net income per chicken carcass with $ 4,929.17. It is concluded that the flour of B. orellana in the diet of broilers allows to obtain productive behavior similar to the conventional feeding with concentrate, substantially reducing the production costs for feeding and improving the pigmentation of the final product.
