Suplementar vacas lecheras con dietas bajas en proteína con aminoácidos específicos, es una estrategia promisoria para contrarrestar el potencial efecto negativo de una deficiencia de proteína metabolizable en la productividad. El objetivo del presente estudio fue cuantificar el desempeño productivo de vacas lactantes y la calidad de la leche ante dos dietas con diferente concentración de proteína cruda (PC) y el suministro de hidroxianálogo de metionina (HMTBA). El estudio se realizó en una finca lechera comercial en la localidad de Alfaro Ruiz, Alajuela, Costa Rica, durante el primer semestre del 2014. Veinte vacas multíparas de la raza Holstein bajo un sistema de pastoreo, fueron agrupadas de acuerdo con los días de lactancia y número de...
