Using accurate nutrient values for ingredients is of vital importance for efficient diet formulation. The net energy (NE) system accounts for the real available amount of feedstuff energy for body maintenance and production as it considers energy dis

The Moorepark St. Gilles grass growth (MoSt GG) model has been developed to predict grass growth taking account of the water and nitrogen (N) fluxes at the paddock level. At grazing, the animal plays a specific role in the N fluxes due to urine and f

There is no validated method for estimating pasture intake of dairy goats receiving concentrates and grazing on multispecies swards. The objective of this study was to determine the accuracy of a method based on estimates of faecal output (from ytter
