Maduramicin ammonium, English name is Maduramicin Ammonium, also known as Maduramycin Ammonium, Maduramicin,
Molecular formula is C47H83NO17, molecular weight 934.17.
Maduramicin ammonium is a kind of monoglycosides polyether ionophoric antibiotics that American Cyanamid Company develops, with its ammonium
Presented in salt the most stable.Maduramicin ammonium is to be produced by microorganism Actinomadurayumaensis fermentation, and it is to many
Gram positive bacteria is effective, has the widest anticoccidial spectrum, can serve as coccidiosis agent for killing, kill the parasite in host,
It all has coccidiostat activity to zygoblast and first generation schizont, eases up tender Amy ear, heap-type Amy ear, Bu Shi Amy ear
Release Amy ear, displacement Amy ear and Eimeria Necatrix and have good effect.
Maduramicin ammonium is white crystalline powder, and fusing point is 165 ~ 167 DEG C, water insoluble, dissolves in organic solvent, its
Not there is mutagenic action, according to the radioactivity determination of 14C labelled compound, after feeding chicken 7 days with the dosage of 55E-6, drug withdrawal 1
It is butchered, and chicken body is respectively organized not measuring residual quantity.Owing to its anticoccidial spectrum is wide, it is not likely to produce drug resistance, therefore applies very
Extensively.But its consumption is minimum, and safety range is the narrowest, it is recommended to use dosage and toxic dose very close to, such as production practices
Middle improper use, it is easy to cause poultry to be poisoned, economic loss is heavy.At present, the product of each producer, animal-use drug on market
Effect difference afterwards is the biggest, it is also very desirable to the optimum formulation protocol of a kind of standard.
Summary of the invention
