Immature corn with some grain development can still be a good quality forage source for livestock. Whole plant digestibility is slightly reduced, fiber content is higher and crude protein content is higher. The starch content will be lower for immature silage, but sugar content of the stalks is higher. Fiber digestibility will depend on two factors: 1) presence of fungal disease or nitrogen deficiency will reduce fiber digestibility and 2) the growing season the plants received during the vegetative stage with wetter than normal moisture levels typically lowering fiber digestibility.
