Effect of route of administration of lasalocid on response of young dairy calves [PDF]
, 1988 Forty newborn bull calves were assigned to one of four feeding groups. The feeds either contained lasalocid in milk (M), prestarter (PS), and starter (S); lasalocid in PS and S; lasalocid in S only; or no lasalocid.

The Journal of Antibiotics, 1974 The biosynthesis of lasalocid A (formerly antibiotic X-537 A) in cultures of Strepto-myces lasaliensis has been studied using 13C- and 14C-labelled precursors. The antibiotic is derived from five acetate, four propionate and three butyrate units. This study has provided the first illustration of an ethyl group arising from butyrate and 2-ethylmalonate.

Cylinder Plate Assay for Lasalocid Sodium
Journal of AOAC INTERNATIONAL, 1974 Abstract A microbiological assay method is described for the determination of the coccidiostat lasalocid sodium in premixes and finished poultry feeds. Premixes are extracted with absolute methanol and diluted to assay range with 25% methanol in the final dilution.
