- 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.
