Abstract
The present invention is directed to rumen-bypass preparations for ruminants composed of a core preparation and a coating layer applied thereonto, characterized in that the core preparation contains from 50 to 90% by weight, based on the core preparation, of a biologically-active substance, that the active substance has been dispersed in from 10 to 50% by weight of a protective substance, and that the coating layer applied onto the core preparation is made of from at least one material selected among linear and branched, saturated and unsaturated aliphatic C.sub.12-24 monocarboxylates, polymers insoluble in the neutral region but soluble in the acidic region, and zein. Use of protective substances originating in natural substances and being harmless to the ecological system makes it possible to obtain rumen-bypass preparations which contain biologically-active substances at a high concentration and are advantageous economically.
