Poultry farming has become a lucrative industry to produce a reasonably priced protein food source. But studies show that the most waste in this industry is food waste that appears at an undesirable conversion ratio. In the present study, technical, technological and managerial factors affecting these wastes have been investigated. For this purpose, descriptive and analytical research methods were used. The results showed that among the three factors studied, technical factors include high poultry capacity, lack of official activity license, not using feed and chopped berries; Technological factors include preparing food from one source, especially from informal sources, improper use of the entrance disinfection pond and hygrometer in the halls, using the window in the combined hall ventilation system, incorrect use of the hall disinfection technologies; Finally, managerial factors include a long interval between two hatcheries (leading to fewer hatches per year), an increase in the number of chicks in a rearing period, an early delivery of chickens to the slaughterhouse, and ignorance of managers. The standard of feed waste, excessive feeding and improper distribution of feed in the hall, have affected the high feed conversion ratio. Suggested solutions to reduce food waste are presented in this article.
