The mineral composition of animal feed has undergone major shifts due to soil degradation, intensive cropping, and evolving genetic potential of livestock. Conventional mineral mixtures, formulated decades ago, are increasingly insufficient to meet the nutritional demands of modern production systems. Evidence indicates that declining soil fertility has reduced essential trace minerals in fodder crops, predisposing animals to metabolic and reproductive disorders. Genetic progress in dairy and poultry has further elevated nutrient requirements, necessitating updated formulations. Additionally, environmental stressors such as heat and water quality variations influence electrolyte and mineral needs. Recent approaches emphasize customized, species- and stage-specific mineral supplementation, bioavailable chelated or nano forms, and precision feeding strategies that integrate digital monitoring and controlled-release technologies. These interventions improve growth, fertility, immune function, and feed efficiency, while reducing excretion and environmental pollution. Transitioning from generic to data-driven mineral mixtures represents a vital step towards sustainable livestock production.
