Supplementing with fresh barley grass in a typical daily diet of a cow in mid lactation improves milk production, increases fertility and gives rise to a healthier animal requiring less veterinarian care. Barley grown hydroponically as a supplemental feed not only keeps dairy cattle healthy but can give premium prices from higher grades of butter fat in the milk. Each kilogram of barley fodder is equivalent nutritionally to 3kgs of lucerne.

In one study of milk production, with a diet of barley fodder versus one of normal feeds such as grain, hay or silage, a group of 60 cows on a barley fodder diet increased milk production by 10.07% over the control group. In addition, the group fed barley fodder produced a butterfat content of 14.26% higher than those fed a regular diet.
