In broiler Flocks, the fertility rate decreases with increasing age from 40 to 45 weeks. Therefore, different methods are used to compensate for the reduced fertility caused by the aging of the rooster that the most important of them is the movement inside the rooster flocks or inter-spiking. Unlike spikes which always is accompanied by a risk of different contamination from another farm to the flock. In this method, there is no concern about the introduction of contamination into the farm, which is one of the most important advantages of this method. In this research, income and expenditure data were used from 2016 and 2017 for estimating the cash flow from the “Arta Joojeh” broiler chickens producer in Ardebil province. Using a bioeconomic model that were designed and collected from broiler Breeding Farms, the estimation of the economic value of one-day-old chicks and the survival rate of rooster herd in different movement conditions were determined. The economic value of a trait is defined as the increase in the profit derived from an animal when the performance of the animal increases for the desired trait while performance for other trait remains constant. Types of movement inside the rooster flocks methods indicated that the highest percentage of hatch and income were in the 32% displacement and the lowest hatch and income were in the 44% displacement. In such a way that 32% of the displacement of the rooster flock is considered to be the most profitable and the highest economic value of broiler chicks, as well as the highest rooster survival rate (less casualties). The results of this study showed that the use of displacements inside the rooster flocks is very useful and effective according to the conditions of broiler chickens to maintain and compensate for the fertility decline due to the aging of the rooster flocks and also to improve the economic outflow of the system One-day-old broiler production.
