	abstract = {Despite a perceived reliance of horses on pasture there are limited data on efficiency of pasture utilisation in equine production
systems. The unique equine behaviour characteristics of highly selective browsing, combined with faecal avoidance, provide
distinct grazing management challenges compared to those of ruminants. Data reported here show that faecal avoidance results in
the establishment of lawns and roughs (overgrazed and poorly grazed areas, respectively) with it estimated that only 70\% of the
total pasture DM/ha on offer is utilised by horses. During spring, lawns contained more grass (74\% vs 53\%) and clover (5\% vs 3\%)
and less weeds (2\% vs. 11\%) and dead matter (19\% vs. 33\%) than did roughs. Weanlings will start to graze roughs once the lawns
are <1500 kg DM/ha. Roughs, however, will not be grazed within 1 m of a faecal pile. This translates to a lower pasture utilisation
rate in weanlings and the biased grazing pattern means estimates of total pasture DM over-estimate the true available pasture DM.
The relative proportion of pasture in lawns and roughs changes during grazing and prevents the application of a simple correction
factor to estimate available DM. Broodmares had greater rates of pasture utilisation and less bias for consumption of pasture in
areas of roughs than did weanlings.},
