background: coccidiosis is recognized as the parasitic disease that has the greatest economic impact on poultry production. modern poultry production is largely dependent upon anticoccidials. objectives: the aim of the present study was to determine and compare the efficacy of two chemical anticoccidials (clopidol and diclazuril) on oocyst shedding and their probable effects on growth performan...

The European Union Reference Laboratory for Feed Additives (EURL-FA), hosted by the Institute for Reference Materials and Measurements (IRMM) of the Joint Research Centre (JRC), a Directorate General of the European Commission, is, among other tasks, mandated to provide scientific support to National Reference Laboratories (NRLs) in the field of the control of the authorised feed additives . In...

background: in this study, the presence of resistance to diclazuril, amprolium+ethopabate and salinomycin, representing some of the commonest anticoccidials in iran’s poultry industry, against three mixed eimeria field isolates were investigated. methods: three eimeria field isolates, collected from typical broiler farms in iran, were propagated once, inoculated to 480 broilers, comprising 30 c...

The method for confirmatory analysis of clazuril, decoquinate, diclazuril, halofuginone, lasalocid, maduramicin, monensin, narasin, nicarbazin, robenidine, salinomycin, and semduramicin in eggs has been developed and validated. The samples were extracted with acetonitrile, purified on Oasis HLB SPE columns and analysed by liquid chromatography coupled with tandem mass spectrometry. The validati...
