ADDITIVES, FEED COMPOSITIONS AND METHODS FOR IMPROVING RUMINANT FEED UTILIZATION

摘要

At least one compound defined by one of the following formulae: I. p1 where X represents Cl, Br, or-SCH3, and n is 1 or 2; and CH3SO2NHCH2CH2CN (II) have been administered to animals to improve the efficiency of food utilization by these animals. These compounds can be administered orally by combining the compounds with feed compositions and fed to animals such as ruminants with a developed rumen function as well as other animals that ferment fibrous material and vegetable matter in the cecum or colon. These compounds effect the rumen metabolism to increase the production of propionate relative to other volatile fatty acids, particularly acetate and to inhibit methanogenesis.
