More than half of the digested fiber comes from the starch and sugar portion of the corn kernel. Therefore, it is vital for a producer to evaluate the availability of fiber in feed supplies this winter and look at factors such as kernel particles that can make a difference in the nutritional value of their silage. Energy from starch is available only if the material is digested. Smaller kernel particles are digested more easily by the intestines and rumen. Larger particles or whole kernels often are digested without breakdown, resulting in minimal nutritional value and, potentially, acidosis. Fredric Owens, Pioneer senior research scientist talks about starch digestibility and its importance.
