Bioactive Compounds of Barbatimão (Stryphnodendron sp.) as Dietary Additive in Lamb Diets

Agriculture, 2023
This study aimed to evaluate barbatimão bark extracts as a feed additive and substitute for lasalocid sodium (LAS) for feedlot lambs. Lambs were distributed into three treatments: LAS (0.018 g of lasalocid sodium), DBB (1.500 g of dried and milled ...

Lasalocid in Prevention of Turkey Coccidiosis

Poultry Science, 1979
Lasalocid was tested at graded feed concentrations in controlled battery experiments against single and mixed Eimeria species infections in 2-week-old turykey poults. Eimeria meleagrimitis, E. gallopavonis, E. adenoeides, and E. dispersa infected poults medicated with lasalocid at concentrations of 0.15, .0125, .01, .0075, and .005% were heavier ...

The In Vitro Cytotoxic Effects of Ionophore Exposure on Selected Cytoskeletal Proteins of C2C12 Myoblasts

Toxins, 2022
Carboxylic ionophores, such as monensin, salinomycin and lasalocid, are polyether antibiotics used widely in production animals for the control of coccidiosis, as well as for the promotion of growth and feed efficiency.

Biosynthesis of lasalocid. III. Isolation and structure determination of four homologs of lasalocid A.

The Journal of Antibiotics, 1974
Four isomeric homologs of lasalocid A have been isolated from cultures of Streptomyces lasaliensis. The homologs each arise by replacement of one of the four propionate derived methyls in lasalocid A by an ethyl group, which results in each homolog molecule containing four C-ethyls.

Lasalocid or Rumensin to prevent lactic acidosis in cattle [PDF]

, 1980
Lasalocid or Rumensin (monensin) protected cattle gorged with grain from lactic acidosis. Both lasalocid and monensin prevented the decrease in rumen and blood pH and increase in rumen and blood lactic acid (0(-) isomer) usually associated with lactic

BIOSYNTHESIS OF LASALOCID. I

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.
