Abstract

Del tratamiento estadístico de nuestros resultados se deduce: que la urea disminuye la producción de leche y grasa de la misma. Esta disminución es proporcional a la dosis de urea utilizada en el caso del volumen de la leche, mientras que en la producción de grasa, el mayor descenso se obtiene con la ración que contiene el 30 % de urea. El costo de los alimentos necesarios para producir un litro de leche, disminuye el sustituir la veza por la urea, siendo esta disminución más marcada en los animales que consumieron raciones con 30 % de urea.
