The Truth About “Locked Ingredient” Feed Formulas. “Locked ingredient” feed formulas may not
lock in consistent levels of nutrition. That’s because the nutritional profile of each feed ingredient can
vary from load to load depending on seed type, growing conditions and time of harvest. As a result,
one production run may produce the desired product, but the next batch can be quite different nutritionally.
Rest Assured with Our “Restricted” Formulas. Nutrena “restricts” the minimums and maximums
that nutrient levels are allowed to vary – ensuring consistency in product appearance, palatability, and
integrity. By restricting a formula rather than “locking” a formula, you can rest assured that the nutrition
your horse requires will be in every bag of Nutrena® horse feed you purchase.
