Question of the Week
Answer: Grain that has sprouted (if free of mold and other microorganisms) can be fed to cattle with no negative consequence. But in terms of delivering energy and nutrients to livestock, it is generally not advantageous to sprout grains before feeding. Generally, the nutritional quality of the grain is not improved by sprouting them. Germination of the seed utilizes starch (stored energy) that would have otherwise been available to the animal. Since the germinating seed uses up starch, the remaining nutrients (protein, vitamins, and minerals) become more concentrated in the sprouted grain. However, the total amount of these nutrients is not actually higher.
Sprouting can increase the amount of carotene (vitamin A precursor) in grains. Before the development of commercial vitamin supplements, sprouted grains were used as a source of essential vitamins, particularly for poultry during winter months. However, the amount of sprouted grains you would need in order to affect the vitamin A status of your dairy cows is likely impractical, particularly if those animals already have access to pasture or high-quality forage.
