What are the differences between lysine and protein lysine?
Both lysine and protein lysine are feed additives which only differ in their lysine content. Lysine is a conventional feed additive that has 98% lysine content, so it is known as 98-lysine. The relatively new product protein lysine contains 65% lysine and the rest is mainly protein. The production cost of protein lysine is lower compared to lysine. We enjoy further cost savings in the production process since there is no sewage treatment during production.
