  • Average NZ pasture silage ME is about 9.5 MJME/kg DM.  This is low quality feed that will not drive good milk production.  The main reason for poor quality silage is because paddocks are harvested for high yields (covers > 4,000 kg DM/ha) rather than quality.

    Paddocks with high covers will contain ryegrass plants with leaves at the fourth and fifth leave stage. Leaves at this stage are in a state of decay and are of low feed value. The long grass will also shade out clovers and ryegrass daughter tillers to the point they will not survive, and the pasture will open up.

    The best quality silage for milk production needs to be cut as soon as canopy closure occurs, that is about the 3 – 3.5 leaf stage. This is no more than 7-10 days after the paddock would have normally been grazed.

    The benefits of cutting silage at this stage are better quality silage, paddocks back in the rotation earlier, improved pasture persistence through higher tiller survival and greater clover content.
