Evaluación de diferentes niveles de promotor de crecimiento orgánico comercial, en la alimentación de pollos broilers

Abstract

In the acadenic unit of poultry research at the Faculty of livestock Sciences, the ESPOCH, were evaluated different levels of commercial organic growth promoter (0,25 – 0,3 – 0,35 g/kg of food), to be compared against a control treatment (0 g of commercial organic promoter / kg of food), in the feeding of chicken broilers, using 400 experimental units with an average weight of 46,47 g the experimental results were submitted to analysis of variance and means test Duncan separation. To determining best productive responses with T3 treatment (0,35 g of commercial organic promoter / kg of food), for the stage of rearing (up to 28 days), achieving a final weight of 1027,78 g, 981,15 g, feed conversion of 1,67 weight gain. At the stage finish (up to 49 days), final weight of 2895,29 g, weight gain of 1863,2 g, feed conversion of 1,9. In the total stage (0 to 49 days), increase in weight (2848,50 g), more efficient feed conversion of 1,82, and the lower cost/kg of weight gain of 1,23 Usd, the best profitability B/C was 1,14 USD in T3, so it is recommended the use of 0,35 g of NutriFibe/kg of food, as was obtained better productive and economic result in the exploitation of broilers.
