Energy

Silage maize is grown mainly because of its high energy content. Maize for silage will continue to be the main source of energy, although there is ongoing improvement to increase other nutrients such as amino acids and fat content. Although energy is not a nutritional substance, it refers to the caloric value that can be converted from nutrients to maintain metabolic activities. Egypt provides this energy in 2 basic ways:

 

Stems and leaves - Mainly fiber component, 40 - 80% digestible energy (dNDF)

Cob - Mainly starch component, about 100% digestible energy

Their ratio depends on the silage corn variety, harvest timing, sowing date and climatic conditions. In terms of nutrients, the fiber ratio of the corn plant decreases over time, while the starch ratio (from the cob) increases.

 

While other nutrients such as soluble sugars, proteins and fats are present in the silage, they are extremely limited and add little to the overall feed ration.
