Andrological study of two young identical twin bulls.
A study was conducted on two young Italian Holstein bulls obtained by embryonic splitting and, therefore, genetically identical. The andrological evaluation of the subjects revealed a significant difference in semen freezability, valued according to forward motility after thawing (57.34 vs. 46.92; P < 0.01). There was, however, no difference in the quality of fresh semen.
