El objetivo de la investigación fue evaluar el efecto de un alimento peletizado a porcentajes de 3%, 6%, 9%, 12% y 15% de contenido ruminal, se formuló 5 dietas con requerimientos nutricionales de proteína y energía metabolizable para inicio, crecimiento, engorde y acabado. Aplicando un diseño de bloques completamente al azar (DBCA), con 4 bloques y 5 tratamientos empleando 100 aves, además se procesaron los datos con la técnica de análisis de varianza (Prueba F) y la respectiva prueba de comparaciones múltiples (Tukey); evidenciando resultados para consumo de alimento, con diferencias altamente significativas entre los tratamientos T2 con un mayor consumo de 7.083 kg y T5 con un menor consumo de 6.426 kg. En la ganancia de peso se mostró diferencias significativas de 2.883 kg para el tratamiento T2 con mayor ganancia y el T5 con menor ganancia de 2.610 kg. En la conversión al...
