12. Grass Storage

Grass can be stored either as dry hay or as silage, but most grass stored as forage for lactating dairy cows is silage [GIS-29]. Although it is possible to make hay in the Northeast in the spring, the odds are against it. Grass is the most common crop ensiled in the world, followed by corn and alfalfa. Perennial grasses typically have higher fiber levels, which have the potential to limit intake and production. Management of grass for optimum silage fermentation and preservation will maximize the potential of this forage.


Storage of grass harvested in spring is typically as silage. High quality grass between 50 and 60% moisture stored as baleage can make good quality silage if sealed and stored properly.
