Rumen by-pass Lysine HCl

Lysby is a microencapsulated Lysine HCl protected by a pH sensible lipid matrix in order to by-pass the rumen and be highly available in the gut.

Due to its particular chemical structure, Lys-by is resistant to mixing, grinding and pelletizing.

Lys-by combines high rumen bypass value with high bio-availability of Lysine in the gut.
