Summary

On 13 pastures grazed by beef cattle live-weight gain (range, 0·34–1·12 kg/head/day) was significantly correlated with non-green grass content of pasture. In turn, non-green grass in pasture was not significantly correlated with non-green grass in oesophageal extrusa. Live-weight gain was largely explained (adjusted R2 = 0·91) by non-green grass content of pasture, cell-wall content of green-grass leaf and pasture dry matter on offer in a quadratic model. The quadratic form was best understood in terms of pasture growth with which non-green grass content of pasture was significantly and negatively correlated.
