Resumen
RESUMEN: Se realizó un experimento para determinar los requerimientos nutricionales de Proteína Bruta (PB) en aves de postura livianas post-pico de producción durante el primer ciclo de postura. En el experimento se utilizaron 300 gallinas Hy Line W36® de 38 semanas de edad, distribuidas en un diseño experimental irrestrictamente al azar, con cinco tratamientos, cinco repeticiones y 12 aves por unidad experimental. Las aves se alimentaron con una dieta básica de maíz, sorgo y torta de soya, con 2.800 kcal de
EM/kg y cinco niveles de PB (14, 15, 16, 17 y 18%). No se observaron diferencias estadísticas significativas (P>0,05) en la producción de huevo, masa de huevo, consumo de alimento, conversión alimenticia y ganancia de peso corporal de las aves sometidas a los diferentes tratamientos. Por lo tanto, el rendimiento productivo de las aves es independiente del nivel de proteína bruta, siempre y cuando se garanticen los niveles adecuados de energía y aminoácidos limitantes.
