TRACE ELEMENT PLUS COPPER & COBALT 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.
