In turn, they provide humans with an adequate supply and proper balance of energy, minerals, vitamins, and essential amino acids which human metabolism cannot do without.

These variations lead to a marked seasonality of feed supply which is a major constraint to livestock production. As it is generally agreed that a plentiful and balanced nutrient supply is the foundation of efficient livestock production, research at ICARDA during the past 10 years
