Selenium is a powerful trace mineral with far-reaching effects on health, reproduction, and immunity. Working closely with Vitamin E, selenium protects cells from oxidative damage, supports fertility, and helps prevent white muscle disease in kids. Because soils in many regions are naturally deficient, selenium is one of the most important free-choice supplements to keep available. Key Benefits 🛡️ Strengthens Immunity – Supports natural defenses against disease and stress ❤️ Protects Muscles – Prevents white muscle disease and supports heart function 🤰 Boosts Reproduction – Improves fertility, embryo development, and placental health ✨ Works with Vitamin E – Together they form a vital antioxidant team for resilience and vitality Part of the Complete Mineral Buffet Selenium is provided individually so livestock can regulate their intake according to regional soil differences, life stage, or seasonal need. Its narrow safety margin makes the buffet system especially valuable, as animals can self-select what they require without forced dosing.
