Abstract :
The present paper describes two cases of an XXY condition in Chianina cattle. Both young bulls were routinely investigated cytogenetically before entering progeny test stations. Every cell examined in the blood cell cultures showed an XXY constitution. The histological study of the gonads, performed on only one bull, showed degradation of the seminiferous tubules. Only Sertoli cells and hyperplastic interstitial cells were observed.
