Rapid method for the simultaneous determination of six ionophores in feed by liquid chromatography/mass spectrometry.
J. AOAC Int. 95(4) , 1016-22, (2012) A simple and highly sensitive LC/MS method was developed for the simultaneous determination of six ionophores--lasalocid, monensin, laidlomycin, maduramycin, salinomycin, and narasin--in feed. The procedure involved extraction of 1 g of feed with 4 mL of meth... |

Sensitivity of Eimeria field isolates in the United States: responses of nicarbazin-containing anticoccidials.
Poult. Sci. 87(9) , 1760-7, (2008) A series of studies were conducted to assess the drug sensitivity of 26 coccidial field isolates to the anticoccidial effects of nicarbazin (NIC) and narasin + NIC (NAR + NIC). Isolates were collected from typical broiler farms in the United States from 2003 ... |

Determination of narasin and monensin in bovine, swine, and chicken tissues by liquid chromatography with tandem mass spectrometry: first action 2011.24.
J. AOAC Int. 95(4) , 959-91, (2012) The single-laboratory validation (SLV) of an LC-MS/MS method for determination and confirmation of two ionophores, narasin and monensin, in animal tissues is described. The data demonstrated linearity of matrix-matched calibration curves using a weighted (1/x... |

Efficacy of narasin in the prevention of necrotic enteritis in broiler chickens.
Avian Dis. 45(1) , 210-4, (2001) The efficacy of narasin in the control of necrotic enteritis (NE) was investigated in a floor pen study of 2000 broiler chickens using a Clostridium perfringens feed inoculum challenge model. Treatments were 1) nonmedicated, nonchallenged; 2) nonmedicated, ch... |

Rapid time-resolved fluoroimmunoassay for the screening of narasin and salinomycin residues in poultry and eggs.
J. Agric. Food Chem. 52(7) , 1824-8, (2004) Anticoccidial drugs are extensively used in the poultry industry to control the infection of the single-cell protozoa of the genus Eimeria. The most commonly used coccidiostats in poultry are the polyether ionophores such as narasin and salinomycin. This pape... |

The residue levels of narasin in eggs of laying hens fed with unmedicated and medicated feed.
Mol. Nutr. Food. Res. 49(1) , 38-42, (2005) Laying hens were fed contaminated feed containing narasin 2.5 mg/kg for 21 days followed by a 7 day withdrawal period, hens in the control group were fed unmedicated feed. Eggs were collected during trial days 0, 3, 7, 14, 21 and after the withdrawal period o... |

Non-soluble fibres and narasin reduce spontaneous gizzard erosion and ulceration in broiler chickens.
Avian Pathol. 41(2) , 227-34, (2012) The prevalence and severity of gizzard erosion and ulceration syndrome (GEU) in broilers is affected by a number of predisposing and preventive factors. Two broiler experiments with almost identical basal diets were conducted to investigate the effect of diet... |

LC/MS confirmation of ionophores in animal feeds.
J. AOAC Int. 84(3) , 640-7, (2001) A liquid chromatographic/mass spectrometric (LC/MS) electrospray confirmation method has been developed to confirm 4 ionophores (monensin, lasalocid, salinomycin, and narasin) in a variety of animal feeds using a single quadrupole mass spectrometer. The sodiu... |
