The single largest ingredient in livestock and poultry diets is grain and its quality begins to degrade the day the crop is harvested. There are several steps in the supply chain through which grain is transported, stored and processed. Each step increases losses in quality, quantity and nutrient content resulting in a significant revenue loss. Preservation of grain quality as it passes through the supply chain means better animal health and performance. After harvest and during storage, mold growth consumes the nutritional value of grain. Application of grain preservatives control mold growth and helps maintain the quality of the grain.
