The practice of providing ungulates with unrestrained access to mineral supplements allows animals to self-regulate their intake based on individual needs and physiological status. This system contrasts with force-feeding, or top-dressing feed with minerals, ensuring each animal consumes nutrients proportionate to requirements.
This method promotes optimal health and productivity. Animals can proactively address mineral deficiencies, supporting vital functions such as immune response, growth, and reproduction. Historically, livestock management relied heavily on instinct; this approach provides a refined method of satisfying those natural urges.
