Evaluation of Polyether Ionophores against Coccidiosis in Broiler Chicken
The efficacy of three polyether ionophores viz. salinomycin, monensin and maduramicin was evaluated in poultry. Dayold chicks (n=350) were randomly divided into seven groups of 50 chicks each. The drugs were administered as feed premix from day one onwards. The chicks at 14-day of age were initially infected with 20,000 sporulated viable oocysts of Eimeria tenella and challenged with 40,000 spo...
متن کاملCP-82,009, a potent polyether anticoccidial related to septamycin and produced by Actinomadura sp.
A new polyether antibiotic CP-82,009 (C49H84O17) was isolated by solvent extraction from the fermentation broth of Actinomadura sp. (ATCC 53676). Following purification by column chromatography and crystallization, the structure of CP-82,009 was elucidated by spectroscopic (NMR and MS) methods. The absolute stereochemistry was determined by a single crystal X-ray analysis of the corresponding r...
متن کاملTrace Level Determination of Polyether Ionophores in Feed
A liquid chromatography-mass spectrometric method was developed and validated to determine six polyether ionophores (lasalocid sodium, monensin sodium, salinomycin sodium, narasin, maduramicin ammonium alpha, and semduramicin sodium) in feed samples. The method developed was very straightforward, involving extraction with 84% acetonitrile of the coccidiostats from the feed samples and filtratio...
متن کاملGrowth performance parameters in chicken experimental coccidiosis treated with Diclazuril and Clopidol: The need for assessing new anticoccidial resources
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...
متن کاملPeriodicity in collision-induced and remote-bond activation of alkali metal ions attached to polyether ionophores.
The collision-induced dissociation of lasalocid and monensin A bound to alkali metal cations has been investigated using electrospray MS/MS. The binding affinity for the metal cations, as measured with collision-induced dissociation, was found to depend on their ionic radius, decreasing with increasing radius. Monensin A was observed to have a greater binding affinity for alkali metal cations t...
