Trace elements, though required in minute quantities (less than 100 mg/kg dry matter), are essential for maintaining health andimmunity. They are involved in growth, production and reproduction. Trace elements act as cofactors of enzymes which areimportant to the immunity of animal. Superoxide dismutase , glutathione reductase, glutathione peroxidase, thioredoxinreductase, ceruloplasmin and catalase are important enzymes that have trace elements as cofactors. These enzymes act asantioxidants and prevent oxidative stress by neutralizing oxidants produced under different stresses. Besides, trace elementscontribute to general health of animal thereby enhancing disease resistance. Trace elements are important for properfunctioning of a number of enzymes and proteins which are involved in many physiological, biochemical and metabolicprocesses that contribute to growth and production. Overall, trace elements improve immune competence and productiveperformance.
