Liquid Chromatographic Determination of Lasalocid in Premixes

Journal of AOAC INTERNATIONAL, 1978
Abstract A high pressure liquid chromatographic (HPLC) method has been developed to determine lasalocid in premixes. The method is simple and rapid, requiring an extraction of the drug and separation of insoluble material before HPLC. Elution times are typically &lt;10 min per sample.

Effects of Lasalocid on Performance of Lactating Dairy Cows

Journal of Dairy Science, 1999
Sixty lactating dairy cows (30 multiparous and 30 primiparous) were used in a completely randomized block design to determine the effect of lasalocid supplementation on dairy cow performance. Starting wk 2 prepartum and lasting through wk 17 of lactation, cows received one of three experimental diets.

Lasalocid-Sulfur Amino Acid Interrelationship in the Chick

Poultry Science, 1980
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.
