A veterinary preparation comprising an effective amount of an anthelmintic agent, preferably fenbendazole, and a non-toxic amount of selenium salt, preferably sodium selenate, effective to prevent selenium deficiency in an animal. Preferably, a non-toxic amount of a cobalt salt effective to prevent cobalt deficiency in an animal is also included. By combining selenium with an anthelmintic agent, the safety margin for selenium is greatly increased. |
