Olsson’s Trace Element is a macro mineral supplement designed for a broad range of mineral deficiencies. Balancing these essential elements results in the efficient breakdown of feed consumed by the animal. Deficiencies in copper, iron, zinc, manganese, cobalt, iodine, & selenium can reduce the animal’s growth and reproduction rates, and result in less efficient feed conversion and depressed immunity. Balancing these elements will improve general production of the herd. Trace Element with Copper & Cobalt can be used year round and fed on an ad lib basis.
