Manganese (Mn) is an important trace element in poultry nutrition and feeding due to its function in eggshell and bone development, enzymes function and metabolism of nutrients. The nutritional adequacy of Mn is necessary for the enzyme Mn-superoxide dismutase (SOD), therefore research dealing with this enzyme is of current interest. Manganese was reported to prevent perosis in young broilers and in laying hens dietary Mn deficiency decreases egg production and shell thickness. The present review paper reports an overview on the currently available literature related to the influence of different forms of dietary Mn on productive performance, meat and egg quality, fertility and hatchability indexes in poultry (broiler chickens, laying hens, breeders and ducks). Available studies demonstrated that organic sources of Mn such as aminoacids complexes, proteinates and chelates have higher Mn bioavailability compared to commonly used inorganic Mn forms; nevertheless, existing findings remain still controversial.
