Linear regression equations have been obtained to directly calculatenutrient requirements of dairy cattle (TDN, DE, ME, NEL,CP, Ca, P, Vitamin A and Vitamin D) on differentphysiological stages: maintenance, pregnancy and milkproduction based on NRC nutrient requirements tables. TheR-square was calculated for each equation to establish thedegree of adjustment.Se determinaron ecuaciones de regresión lineal para calcular en forma directa los requerimientos nutricionales del ganado de leche (TND, ED, EM, ENL, PC, Ca, P, Vitamina Ay Vitamina D) en diferentes etapasfisiológicas: mantenimiento, gestación y producción del ganadode leche. Se utilizó como base la tabla de requerimientos nutricionalesdel NRC. En todas las ecuaciones se calculó el coef...
