              Abstract 
 
              Trace elements, though required in 
              minute quantities (less than 100 mg/kg dry matter), are essential 
              for maintaining health and immunity. They are involved in growth, 
              production and reproduction. Trace elements act as cofactors of 
              enzymes which are important to the immunity of animal. Superoxide 
              dismutase, glutathione reductase, glutathione peroxidase, 
              thioredoxin reductase, ceruloplasmin and catalase are important 
              enzymes that have trace elements as cofactors. These enzymes act 
              as antioxidants and prevent oxidative stress by neutralizing 
              oxidants produced under different stresses. Besides, trace 
              elements contribute to general health of animal thereby enhancing 
              disease resistance. Trace elements are important for proper 
              functioning of a number of enzymes and proteins which are involved 
              in many physiological, biochemical and metabolic processes that 
              contribute to growth and production. Overall, trace elements 
              improve immune competence and productive performance. Key words: animals, health, immunity, production, 
              reproduction, trace minerals
