Economic costs of outdoor ranging in slow-growing broiler genotypes

This study evaluates the economic and performance outcomes of three genetic strains—S757N, JA757, and C—under organic ranging conditions. It compares high- and low-ranger subgroups across growth rates, feed efficiency, and production costs. The dual-purpose C strain showed poor feed efficiency and lower growth, leading to higher costs due to extended rearing periods. In contrast, the medium-growing JA757 strain demonstrated lower production costs and better economic efficiency, despite regional restrictions in some countries. The S757N strain, while slower-growing, remained more cost-effective than C. Data from INRAE and on-farm trials confirm that genetic selection for moderate growth and efficient ranging behavior can reduce production costs in organic systems. The PPILOW project, funded by the EU’s Horizon 2020 programme, highlights the importance of balancing genetic potential with economic sustainability in free-range broiler production.
