Abstract and keywords

The aim of the study was to investigate the effects of caponisation on bone development of males of two native breeds in Poland.
The weight, length and cross-sectional area of tibiae and femora were measured, densitometric measurements and tests of strength were determined and dimensions were calculated.
Breed and caponisation did not influence bone weight and length. Higher mechanical strength of the femur was found in entire males, mainly in the Polbar breed. Tibial strength was reduced in capons of the Green Partridge breed. Maximum elastic strength was greater in the Polbar, irrespective of caponisation. Bone cross-sectional area was influenced by breed, while caponisation reduced femoral bone mineral density in both breeds.
Caponisation thus increased growth rate but had adverse effects on bone development.
Caponisation had fewer negative effects in the Polbar than in the Greenleg Partridge.
