Good corn silage hybrids have high yields, high energy, high digestibility, and good animal performance. Critical to maximize silage yields is the selection of the right variety. Similarly, agronomical practices can change not only corn silage yield per hectare but also its nutritive value.
With lower corn silage yields, there is a greater need for livestock supplementation, which increases feed costs. Since starch is deposited in the kernels, the amount of grain in the ration is associated with the energy content of the silage. In the past, the rule of thumb for the corn silage grain-to-forage ratio was 50:50.
