Nutrient requirements of dairy cattle.


  • Jorge Alberto Elizondo-Salazar Universidad de Costa Rica, Estación Experimental Alfredo Volio Mata



Linear regression equations have been obtained to directly calculate
nutrient requirements of dairy cattle (TDN, DE, ME, NEL,
CP, Ca, P, Vitamin A and Vitamin D) on different
physiological stages: maintenance, pregnancy and milk
production based on NRC nutrient requirements tables. The
R-square was calculated for each equation to establish the
degree of adjustment.
