MasterPlex provides a unique combination of crucial complexed (organic) trace minerals which yield greater bioavailability that is especially crucial for stressed cattle. Trace minerals fuel biochemical processes that are involved in metabolic reactions, enzyme activation, antioxidant responses and immune system function. Needed in very small amounts, powerful trace minerals can help unleash the performance potential within your herd. Rations containing insufficient amounts of trace minerals hinder cattle from attaining maximum production.
