Animal Feeds

Animal feed is the food given to domestic animals which consists of two basic types: fodder and forage.

 
"Fodder" refers particularly to foods given to the animals (plants cut), rather than that which they forage for themselves. 
"Forage" is plant material (plant leaves & stems) eaten by grazing livestock. Forage itself means only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops (hay or silage).
