Lasalocid 15% Premix is an essential veterinary medication used to prevent and treat coccidiosis in poultry. Specifically, it targets the protozoan parasites of the genus Eimeria, which cause this debilitating disease. Lasalocid is produced by strains of Streptomyces lasaliensis. It acts as an ionophore, making neutral complexes with monovalent and divalent cations and transporting them through apolar phases, including lipid bilayer membranes. This mechanism helps control coccidiosis effectively. However, it should never be administered to non-target species, as horses and dogs are highly susceptible to its toxic effects
