Environmental pollution is defined as the disruption of normal ecological balance with emmision of various substances and energy residues as a result of human activities. Animal production is one of the major human activity that enables this emission to increase significantly. Although ruminants play an important role in the effects of animal production on environmental pollutant emissions, the effects of poultry production and broiler production are also worth considering. As in all livestock types, the main factor that has a direct impact on environmental pollutant emissions is feeding for this animal types too. High nutrient needs of broilers and production processes of feed containing these nutrients; greenhouse gas causes increased nitrogen and phosphorus emissions; consequently, they cause air, soil and water pollution to multiply. Changes in protein and amino acid levels or the use of certain feed additives in feeds affect the emission value of broiler production. In addition, the feeding methods also has an effect on these emission values. When these effects are taken into consideration, it is possible to reduce the emission values in broiler production. In this review, environmental effects of broiler nutrition examined in terms of feed production, nutrient emission by manure, presentation of feed and feed form.
