Antibiotic A-28086 complex, comprising microbiologically active, structurally related factors A, B, and D, produced by submerged aerobic fermentation of Streptomyces aureofaciens NRRL 5758. Individual factors A, B, and D are separated and isolated by chromatography. The A-28086 antibiotics are antibacterial, antifungal, antiviral, anti-PPLO, anticoccidial, insecticidal and acaricidal agents and also increase feed-utilization efficiency in ruminants.
CROSS-REFERENCE TO RELATED APPLICATION This is a division, of copending application Ser. No. 569,740 filed Apr. 21, 1975, which in turn is a continuation-in-part of application Ser. No. 477,954, filed June 10, 1974, now abandoned.
Methods of preventing and controlling coccidiosis in ruminant animals and for improving rate of weight gain by oral administration of salinomycin or 4-methylsalinomycin are disclosed.
Agents containing Salinomycin for oral administration to domestic animals which do not digest cellulose in the rumen, particularly pigs, are disclosed, for instance for the prophylaxis or treatment of disease and/or for improvement of growth.
