The present study was aimed to determine the most appropriate stocking density in breeding partridges by considering animal welfare. For this purpose, feed consumption, egg production and quality parameters, fertility, survival rate, feather condition score, cortisol and testosterone hormones were examined. A total of 552 breeding partridges with a ratio of 3 females to 1 male were used in the study and the groups were designed as 0.25 m2, 0.19 m2, 0.15 m2 and 0.11 m2 per partridge (4 groups and 3 replicates). Increasing the stocking density had no effect on feed consumption while it negatively affected egg production. Higher stocking density had a negative effect on the feather condition score which is similar to those for egg production. A parallel decrease in feed consumption and egg production was observed with the temperature increases according to the summer months. Stocking density had no effect on egg quality parameters, fertility rate, survival rate, testosterone and cortisol. In conclusion, a larger allowed space with 0.20 m2/bird or more benefits egg production and the welfare degree of chukar partridges.
