The predominant feed source for deer is permanent pasture (ryegrass/white clover). Winter or summer crops (swedes, rape, turnips and fodder beet), lucerne, silage, grain or Palm Kernel Expeller (PKE) are used to improve the performance at different times of the year.
Seasonal pasture curves and pasture quality vary widely throughout New Zealand.
Research has shown that animal performance is affected by pasture quality.
