Meeting trace mineral requirements is important for cattle performance and health. However, exceeding trace mineral needs does not result in improved performance and depending on the amount of excess can lead to death or reductions in growth and reproduction. An increasing number of deaths associated with copper and other trace mineral toxicities are showing up. To meet animal requirements and help avoid trace mineral excesses it is a good practice to only use a single well-formulated mineral supplement. Using multiple products (e.g. loose mineral supplements, mineral tubs, mineral blocks, etc.) at the same time is costly and can lead to excess.
