Abstract
Pasture dry matter (DM) estimates are used by dairy farmers and their advisers for feed planmng principally during April to September. The three primary estimates required are: average farm cover, pre-grazing herbage on offer, and post-grazing residue. Average farm cover can be approximated by averaging paddocks with the highest and lowest DM. Various 'short-cut' methods (pasture height, weighted disc, pasture 'probe') were evaluated during 1984 and have provided calibration equations for 'feed budgeting' of pre-calving feed. Such equations could be used for day-to-day feeding calculations during autumn to spring provided their limitabons are recognised.
