Summary and Implications
There is renewed interest in hydroponic fodder systems for dairy, livestock or poultry operations. The thought of putting one pound of seed into a hydroponic system producing 10 times its weight in fodder is appealing. However, the actual dry matter weight of the original grain to the fodder produced may or may not increase. Research reviews are very inconsistent in any dry matter production or animal performance benefits. The aim of this analysis is to assist producers weigh the high production costs of hydroponic fodder systems relative to any real or perceived nutritional benefits gained from feeding hydroponic fodder.
