QLF liquid supplements are superior carriers of nonprotein nitrogen (NPN) vitamins and trace minerals, making them a valuable tool to achieve your supplementation needs.  With the increased costs of ingredients, such as distillers grains, NPN can help offset a significant portion of your needs.  Natural protein is still an important component of the diet but achieving optimal rumen and performance efficiency is best achieved by incorporating both true and NPN sources of protein along with trace minerals predictably distributed within the diet.
