Granulated feed additive with improved color value based on the fermentation broth, which has a) an L-lysine content of 10 to 70% by weight, particularly 30 to 60% by weight (calculated as a base, based on total weight ), b) a water content of 0.1 to 5% by weight based on the total weight, and c) a sulfate / L-lysine ratio of 0.85 to 1.2, calculated according to the formula 2 x [SO42-] / [L-lysine] = ratio. |
