Maize grain

Key points

  • Grains provide cows with starch for energy.
  • Maize grain is higher in energy density and starch content, and has a slower rate of rumen fermentation.
  • Maize may be useful as a complementary grain to wheat:
    • When grain is fed at high levels per cow per day;
    • When cows are freshly calved;
    • When cows are at increased risk of ruminal acidosis, and
    • In hot weather.
  • To optimise milk responses from maize grain, processing prior to feeding needs to carefully control particle size.
