Efecto de la utilización de lactosuero en el rendimiento productivo de pollos Broiler COBB 500 en el cantón Santiago de Méndez.

Abstract

The aim of this study was to evaluate the effect of the use of whey on the productive performance of Cobb 500 broiler chickens in Santiago de Méndez which is a canton in the province of Morona Santiago. The research was field-based and used female broilers of the Cobb 500 broiler line, which were fed the same concentrated feed according to their developmental stages. The 160 one-day-old birds were separated into groups of 10 and placed in an area of 1.32 m2, considering the demand for space until their final development. Previous studies were also analyzed and the different productive indicators of broiler chickens were evaluated. A simple completely randomized design was used for broiler rearing, considering different levels of bovine whey (5%, 10% and 15%) compared to a control treatment. As a result, final weight (3401.48 g), weight gain (3355.33 g), feed consumption (4746.00 g), feed conversion ratio (1.42), carcass yield (81.96%), mortality (0%) and benefit/cost (1.30) reached the highest responses when 15% whey was substituted in the drinking water. It is concluded that the use of bovine whey improves the productive parameters for the poultry fattening sector. It is recommended to carry out research with whey from other species to determine its potential in broiler nutrition, since this by-product is mostly not used by dairy companies.
