Protective effects of cannabidiol against nephrotoxicity of ionophore coccidiostats in HEK-293 cells [PDF]

Journal of Veterinary Research
Veterinary drug residues in the environment threaten public health and animal welfare. Ionophore coccidiostats (lasalocid (LAS), monensin (MON) and narasin (NAR)) are commonly used in animal production.

Trends in Veterinary Drug Residues in US Cattle: Analysing USDA Sampling Data. [PDF]

Vet Med Sci
National US residue monitoring data (2021–2023) were analysed to characterise veterinary drug residue detections in cattle. Detection patterns varied by cattle type, with dairy cows accounting for the highest number of detections and a consistent group of commonly used drugs responsible for most violative and non‐violative findings.

Structural Basis of Sequential Enantioselective Epoxidation by a Flavin-Dependent Monooxygenase in Lasalocid A Biosynthesis. [PDF]

Angew Chem Int Ed Engl
Lsd18 is a flavin‐dependent monooxygenase from Streptomyces lasalocidi that performs two enantioselective epoxidations during lasalocid A biosynthesis. X‐ray crystal structures of Lsd18 bound to a substrate and product analogue illuminate how this enzyme performs multiple epoxidations on the same substrate molecule and how it controls stereoselectivity.

Screening of Chemical Residues and Antimicrobial Resistance in Dehydrated Chicken Feet Intended as Dog Treats: A Pilot Study. [PDF]

Vet Med Int
The pet population is steadily increasing worldwide, and treats, which account for approximately 15% of the pet food market, are the fastest‐growing segment of the pet food industry. However, the widespread use of antimicrobials in poultry farms may pose a direct risk to pets’ health, leading to the emergence of antimicrobial resistance.

Assessment of the application for modification of the terms of the authorisation of the feed additive consisting of <i>Bacillus velezensis</i>ATCC PTA-6737 (PB6) for all pigs, all poultry species for fattening or reared for laying/breeding, laying hens, minor poultry species for laying and ornamental birds (Kemin Europa N.V.). [PDF]

EFSA J
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the preparation consisting of viable spores of Bacillus velezensis ATCC PTA‐6737 (tradename PB6). PB6 is currently authorised for use as a zootechnical additive (functional group: gut flora stabilisers) for all poultry

EFFECT OF LASALOCID SUPPLEMENTATION ON SOME METABOLIC AND ENDOCRINE PARAMETERS IN TURKEY POULTS. [PDF]

Assiut Veterinary Medical Journal, 2006
SUMMARY Lasalocid, a carboxylic ionophore antibiotic, is used frequently in poultry feeds as a coccidiostat, however the present study centered on its role as growth promoter and in steroidogenesis.

INFLUENCE OF DIETARY LASALOCID ON SOME SERUM CHARACTERSTICS AS WELL AS SEMEN QUALITY AND FREEZABILITY IN ADULT BARKI RAMS [PDF]

Assiut Veterinary Medical Journal, 1997
To study the effect of dietary lasalocid on serum insulin, cholesterol, Ca, P, Mg, Zn and Cu as well as semen quality and freezability, a number of six mature Barki rams (about 26 months of age and 46.5kg) were used during the periods of pretreatment ...
