Abstract: 

This study aimed to demonstrate the effect of raising broiler chickens with different densities in the breeding area during the summer season on productive indicators. 2020, where all the experimental birds were subjected to the same environmental conditions, and the research was conducted using 180 chicks from broilers (commercial Ross hybrid). Respectively, all experimental chicks were given vaccinations and immunizations through drinking water according to the approved programs in the experiment. During the experiment, the average live weight, weight gain, average consumption of the amount of feed consumed, the feed conversion factor, and the mortality rate were calculated on a weekly basis. At the end of the experiment, the results showed a significant superiority of the first and second groups, which were raised With a density of 12 – 14 birds / m 2, respectively, the final results were as follows: For the average live weight 1967 – 1967 – 2011 g for the three groups, respectively, while the average feed consumption was (3727 – 3696 – 3685) g, respectively, and the feed conversion factor was 1.998 -1.987 – 1.916, respectively. As for the mortality rate, it was 9.11-11.43-13.66, respectively. Through these results, it was found that the differences were not significant between the first and second groups, while the differences were significant between the first and third groups.

Keywords: Broilers, Birds Density, Productivity Indicators, Mortality rate.
