Corn fodder has energetic grains, these grains contain significant amount of carbohydrates and vitamin A. feeding this seed is recommended for livestock that need high energy.

The quality of fodder corn in a feed depends on the amount of nutrients that the animal can get from that feed in the shortest time. Important factors to determining the quality of fodder and feed include the amount of energy, the amount of fiber, digestibility and amount of consumption for livestock.

Digestibility is generally considered as the most valuable criteria for measuring corn fodder and forage quality because it is closely related to animal performance. When the diet is palatability of corn fodder is not only a factor to evaluating consumption, but also digestibility is a valuable factor. So high speed and ease of digestion of food, increase consumption.

In terms of quality, fodder is the most heterogeneous agricultural product; due to factors such as variety of fodder plants, high production volume and great impact of environmental factors on fodder quality.

Corn fodder and other green fodders can live after cut it down and photosynthesize in the presence of light. When the plants is alive, it can resist the attack of microorganisms, but the dead plant tissue is decomposed by attack of microorganisms. So, the reasons of storage are to stop this degradation and maintain quality and quantity of fodder. This operation is possible in two ways: drying and ensile.
