Alterations of energy metabolism in ruminants supplemented with lasalocid [PDF]
Three trials were conducted to evaluate the alterations of energy metabolism in ruminants fed a forage or concentrate based diet supplemented with or without lasalocid. Trials 1 and 2 were designed in a 2 x 2 Latin Square using 4 post-weaned wethers (avg

Sequential Enzymatic Epoxidation Involved in Polyether Lasalocid Biosynthesis
Enantioselective epoxidation followed by regioselective epoxide opening reaction are the key processes in construction of the polyether skeleton. Recent genetic analysis of ionophore polyether biosynthetic gene clusters suggested that flavin-containing ...

Lasalocid-Sulfur Amino Acid Interrelationship in the Chick
Several experiments were conducted with young healthy chicks to investigate the relationship between lasalocid and sulfur-containing amino acids (SAA). Chicks were housed in heated starter batteries in all experiments and were fed, in all but one trial, a completely purified crystalline amino acid diet.

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