Answer: While the price of mineral is not a definitive indicator of quality, products that are “dirt-cheap” may not be worth much more than dirt itself! Quality ingredients that cattle can utilize efficiently have greater demand and higher value, thus often a higher price. By definition, quality ingredients have a knowledge base behind them that is supported by extraction and refinement processes, as well as research that measures their biological value. A mineral element can be supplied by a variety of forms.
For example, zinc may be provided by zinc sulfate, zinc carbonate, zinc oxide, zinc chloride or one of many organic forms. Some forms are effective for supplementation, while others are less available and provide little or no biological value. However, all of them can be used in a product to meet the tagged specifications for mineral.
