The aim of this study was to determine the effect of caponization on selected morphometric parameters and mineral density of tibiotarsal bones in Green-legged Partridge cockerels. The experiment was conducted on 200 cockerels. At 8 wks of age, 100 birds were surgically castrated. At 12 and 24 wks of age, blood samples were collected from 10 intact cockerels and 10 capons, and the birds were slaughtered. Tibiotarsal bones were dissected from individual birds. Age had a significant effect on tibia weight in both cockerels and capons (P ≤ 0.01), whereas the effect of castration on this parameter was noted in older birds, at 24 wks of age(age x sex category interaction, P ≤ 0.01). Tibiotarsal bones were longer in cockerels than in capons (P ≤ 0.01). The tibiotarsal bones of capons had higher BMD values than the bones of cockerels (P < 0.01)
