measure glycerin. Prior to feeding glycerin, contaminant levels and impurities should be known to ensure the product is safe to feed to livestock. The methanol concentration of crude glycerin is of particular concern and is regulated by the Food and Drug Administration (FDA) and other regulatory agencies if intended for livestock consumption. Servi-Tech has added gas chromatography instrumentation for the specific purpose of measuring methanol in crude glycerin. To date, glycerin has been effectively added as an ingredient in liquid supplements. The sweet liquid can also be used as a conditioning agent to improve palatability of dry diets. Glycerin can effectively control dust and reduce buildup of fines in bunks by preventing separation of ingredients, particularly in total mixed rations containing concentrates with small particle sizes. As the biodiesel industry expands and availability of glycerin increases, there is great potential to include glycerin in livestock diets as a replacement for corn grain. We are pleased to begin offering this testing ability to provide an added service for our feed customers. Did you know? Servi-Tech now has the capability to use High Performance Liquid Chromatography (HPLC) instrumentation to accurately measure glycerin.
