Sourcing maize grain
There are a significant number of grain companies who can supply whole or processed maize grain. Talk to your local maize planting or harvesting contractor or call 0800 PIONEER (746 633) to find the supplier closest to you.
Some farmers are choosing to grow their own supply of maize grain on farm or a run-off. Alternatively the crop can be harvested as earlage or high moisture corn. The latter two products are not suitable for feeding in most meal feeding systems.
