Corn silage harvest techniques
The goal in making corn silage is to efficiently harvest and store the maximum amount of digestible nutrients per unit of land area. This requires that dry matter losses due to harvest and storage be minimized.
The end result, high quality silage, is readily consumed by animals and is capable (with proper supplementation) of inducing high levels of animal product.
