Growing extra leaf area

摘要

With profitability heavily linked to grass use, DairyCo is challenging efficient grassland managers to push their systems even further by following the NZ approach.Grazing paddocks at 3 leaves instead of 2.5 has grown another tonne of grass dry matter (DM) per hectare for a 510-cow herd in Gloucestershire.In practice it meant the additional half a leaf on the milking platform produced 500 tonnes of extra silage for the clamp. The result was a saving of more than10,000 in feed costs for the 2011 winter, says Lydney Park Farm's herd manager Keith Davis.
