The effect of lasalocid on fall calving beef cows [PDF]
Forty-two fall-calving crossbred cows were equally allotted to six pens of seven cow-calf pairs each. Two treatments (0 and 200 mg lasalocid/head/day) with three replications were used to determine the effects of lasalocid on fall-calving beef cows.

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 ...

Lasalocid Sodium Supplementation For Grazing Steers [PDF]
, 1981 Lasalocid sodium (Bovatec) is a feed additive which has been reported to promote growth and improve feed utilization by cattle. The product appears to function by stimulating a more favorable and efficient microbial fermentation of the feed, thus ...

Alterations of energy metabolism in ruminants supplemented with lasalocid [PDF]
, 1994 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

Cytoprotective effect of silybin against lasalocid-induced toxicity in HepG2 cells [PDF]
, 2013 Lasalocid is an ionophore coccidiostatic agent frequently used in poultry. Its extensive use causes the formation of residues in edible tissues and eggs which may pose a risk to consumers. Silybin is the main compound extracted from the herb milk thistle

Sequential Enzymatic Epoxidation Involved in Polyether Lasalocid Biosynthesis
, 2016 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 ...
