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)

Celem badań było określenie wpływu kastracji i wieku na wybrane cechy morfometryczne oraz gęstość mineralną kości piszczelowo-stępowej kogutów zielononóżki kuropatwianej. Materiał do badań stanowiło 200 kogutów, z których 100 poddano kastracji chirurgicznej w wieku 8. tygo-dni. W wieku 12. i 24. tyg. od 10 losowo wybranych kogutów i 10 kapłonów pobrano próby krwi, a następnie po uboju wypreparowano kość piszczelowo-stępową. Stwierdzono, że wiek ptaków wpłynął istotnie na masę kości piszczelowo-stępowej kogutów i kapłonów (P ≤ 0.01), natomiast wpływ kastracji ujawnił się u ptaków starszych, w wieku 24. tyg. (interakcja wiek × kategoria płciowa, P ≤ 0.01). Kość piszczelowo-stępowa była dłuższa u kogu-tów, w porównaniu z kośćmi kapłonów, zarówno w 12., jak i w 24. tyg. (P ≤ 0.01). Kości kapłonów wykazywały wyższe wartości BMD (P < 0.01)
