FREMGANGSM}TE FOR FREMSTILLING AV ANTIBIOTIKUM A28695 A OG B.

摘要

Antibiotics A28695A, A28695B, and their physiologically-acceptable salts improve the digestive efficiency of certain animals. Oral administration of the antibiotics to ruminant animals having a developed rumen function, and to animals which ferment fibrous vegetable matter in the cecum, changes the digestive fermentation to produce more propionates relative to the production of acetates.
