Anticoccidial Activity of Lasalocid (X-537A) in Chicks

Poultry Science, 1974
Abstract Lasalocid (X-537A, Ro 2-2985 sodium salt), at graded feed concentrations, was tested in controlled battery experiments against various strains of single and mixed Eimeria species infections. The experimental data indicated that lasalocid, at dosages of 0.01, 0.0075 and 0.005%, demonstrated a high degree of anticoccidial activity in terms of ...
