Antibiotic A26201-1 and antibiotic A26201-2 are produced by the novel microorganism, Actinoplanes species A26201 (ATCC 39573), under aqueous aerobic fermentation conditions. The antibiotics are useful for inhibiting bacteria, particularly gram positive bacteria, and are also useful for promoting the growth of monogastric and ruminant animals.

The invention discloses a method of treating swine dysentery by the administration of an animal feed composition containing an effective amount of an alkoxysilane compound such as 3-(triethoxysilyl)propyloctadecyldimethyl ammonium chloride.

Alkoxysilane compounds in the treatment of swine dysentery

Quaternary ammonium phenates containing a 3-chloro-2-propenyl substituent group attached to the nitrogen atom and having as other substitutent groups attached to the nitrogen atoms (1) a C.sub.8 -C.sub.18 alkyl group, (2) a one carbon, two carbon, C.sub.8 -C.sub.18 alkyl or a 3-chloro-2-propenyl group, (3) a one carbon or two carbon alkyl or a 3-chloro-2-propenyl group, and (4) a phenate group, wherein not more than a total of two 3-chloro-2-propenyl groups are present in the molecule. The compounds have antibacterial and antifungal utility.
