Acid poly (cyclic ether) compound, process for its preparation and biologically pure microorganism culture for use in the process, as well as compound feed and a process for promoting pig or bovine growth

摘要

An acidic polycyclic ether antibiotic, having structure established by X-ray crystallography, is formed by fermentation of a novel microorganism, Actinomadura sp. ATCC 53708. This novel antibiotic is useful as an anticoccidial in chickens, in the prevention or treatment of swine dysentery, and as a growth promotant in cattle and swine.
