Hydroponic fodder is a particularly nutritious feed, rich in protein and vitamins such as ß-carotene, trace elements and enzymes. It may also offer the advantage of a continuous availability. A pilot plant for hydroponically production of germinating seeds was built in an area of the same farm where the trial took place. Three homogeneous groups of 30 Jonica breed goats in lactation (4 th-5 th parity) were used to evaluate the effects of two different levels of partial dietary substitution with hydroponically germinating (h.g.) oat on plasma levels of cortisol and milk production. Germinated oat was used after 7 days of hydroponic growth. Control group (T) received only feed (fodder and oat integrated with complement feed). The other 2 groups were fed on diet containing different levels (1,5Kg - group A; 3Kg - group B) of hydroponically germinating oat. Goats showed a small interest in fresh feed during the trial period. The integration with hydroponically germinating oat in partial substitution of the traditional feed in the diet of goat did not significantly affect biochemical and haematological parameters.
