Copaiba oleoresin as a substitute for sodium lasalocid in finishing diets for lambs: carcass characteristics and meat quality

New Zealand Journal of Agricultural Research
The aim of this study was to evaluate the effects of copaiba oleoresin (CO) as a substitute for sodium lasalocid on the carcass characteristics and meat quality of feedlot lambs fed a high-concentrate diet. Twenty-four Pantaneiro lambs, aged 152 days and

Safety of lasalocid in turkeys and its compatibility with tiamulin

Veterinary Record, 1988
An investigation involving 640 turkeys demonstrated that the inclusion of lasalocid continuously from day-old to 16 weeks of age, at levels up to 375 ppm in the feed, produced no adverse effects; furthermore, the inclusion of 125 ppm lasalocid in the feed was compatible with the administration of 250 ppm tiamulin in the drinking water continuously for ...

Evaluation of Lasalocid in Salt Against Ovine Coccidia

American Journal of Veterinary Research, 1981
SUMMARY Lasalocid at a level of 0.75% in free-choice granulated salt was highly efficacious against naturally acquired coccidia infections in lambs maintained in semiconfinement. Treated lambs consumed 18 g of medicated salt/day, reflecting an average daily lasalocid dosage of 4.3 mg/kg of body weight.

The decrease of lasalocid residue in the edible tissues by silymarin supplementation of chicken diet

Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment, 2019
Widespread use of coccidiostats, in spite of beneficial control of protozoan infections in poultry, implies a risk of residues in edible tissues, and there is increasing interest in the development of strategies for prevention of veterinary drugs residue

Effect of lasalocid, monensin and thiopeptin on rumen protozoa

Research in Veterinary Science, 1986
The effects of lasalocid, monensin and thiopeptin on the total number and the generic composition of rumen protozoa were determined in vivo and in vitro. Feeding lasalocid or monensin to cattle on either high grain or high roughage diets reduced total protozoal counts.

Coccidiostats in milk: development of a multi-residue method and transfer of salinomycin and lasalocid from contaminated feed

Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment, 2018
A confirmatory multi-residue method was developed for the determination in milk of 19 coccidiostats (amprolium, arprinocid, clazuril, clopidol, decoquinate, diclazuril, ethopabate, halofuginone, lasalocid, maduramicin, monensin, narasin, nicarbazin ...

Fitness of Amines for Pseudocyclic Conformation of Lasalocid A

Journal of Biomolecular Structure and Dynamics, 1995
Ionophore lasalocid A selectively transports amines across lipid membranes. The structures of amine-lasalocid complexes were calculated by a molecular mechanics technique. Four typical catecholamines were considered: serotonin, dopamine, noradrenaline and adrenaline.

The Total Synthesis of Lasalocid A

1980
A total asymmetric synthesis of the "right half ketone" of the stereo-complex polyether antibiotic, lasalocid A, is described. The [3,3] sigmatropic rearrangements of 0-silylketene acetals derived from esters of 1,4-anhydro-pent-1-enitols (furanoid glycals) and 1,5-anhydro-hex-1-enitols (pyranoid glycals) provided α-substituted-2,5-dihydrofuran-2 ...

Control of coccidia in young calves using lasalocid

Australian Veterinary Journal, 1995
SUMMARY Thirty‐six, 2‐ to 4‐day‐old Friesian bull calves were divided into 4 groups and fed milk replacer and calf starter pellets ad libitum in separate pens. Four treatments were applied; lasalocid in milk (1 mg/kg body weight/day) (M), lasalocid in starter (F), lasalocid in both milk and starter (M+F) and untreated (C).
