Abstract: A trial was conducted to investigate to effects of feed type (pellet and mash) on ascites in broiler. A total of 208 male chicks were used in this study. Pellet and mash feed group were formed in the study, pellet feed group fed on pellet and mash feed group fed on mash feed. Half of the animals from each group were moved to compartment with 16°C after 21 day. Body weights, feed conversion, weight gain and feed consumption of the chicks were calculated and mortality from ascites was recorded daily. On 42 day, blood samples were collected to determine hematocrit values. End of the study it was determined that feed type has no effect on body weight, weight gain, feed consumption and feed conversion rate. However, mash feed reduced the incidence of ascites.
