N2  - Merino wethers were grazed for four years on Phalaris-subterranean clover pastures at four stocking rates. Measurements over two years showed that wear of incisor teeth increased substantially with stocking rate. This wear was closely associated with intake of silica by the sheep. After the experiment marked carry-over effects in wool production and live weight were observed in adult wethers. Significantly more wool was produced by sheep previously grazing at high stocking rates. Possible reasons for this effect are discussed.
