Pasture consumption calculator
The Pasture Consumption Calculator provides the Australian dairy industry with a robust, scientifically sound method for back-calculating on-farm annual pasture removal (t DM/ha) and an estimation of annual feed conversion efficiency of the milking herd.
This calculator is based on generalised equations of ruminant requirements for metabolisable energy (ME, MJ/kg DM) for various physiological processes published in 'Nutrient Requirements of Domesticated Ruminants' (CSIRO, 2007), and differs from other approaches which do not fully account for metabolisable energy requirements.
The equations used to estimate metabolisable energy requirements are described in:
