Quick answer:<\/strong> Feed-grade lysine comes mainly as L-lysine HCl (98.5% purity, about 78.8% lysine) or L-lysine sulphate (about 50\u201355% lysine plus other nutrients). Compare products on price per kilogram of actual lysine, not per bag. Check the certificate of analysis, moisture and particle flow, and store bags sealed and dry.<\/p>\n

How to compare prices<\/h2>\n

Divide the price per kilogram by the lysine content. For example, a product with 78.8% lysine delivers more lysine per kilogram than one with 54%, so it may be cheaper per unit of lysine even if the bag price is higher.<\/p>\n
