ABSTRACT
The aim of the study was to determine whether immature bovine oocytes selected by morphology
and BCB test (brilliant cresyl blue) and used for in vitro embryo production would increase the
blastocyst rate when inseminated with sperm derived from bulls of reduced in vitro fertilizability.
To relate oocyte quality and bull effect to blastocyst quality, morphology, ability for hatching and
caspase-3 activity (marker of apoptosis) were evaluated.
Both, oocytes originating from BCB+ and from Control COCs exhibited higher cleavage and
blastocyst rates (P<0.001) compared with BCB- oocytes. Significant differences in cleavage and
blastocyst rates between the two bulls were observed. The highest blastocyst rate was noticed for
BCB+ oocytes, regardless the bull. Comparison of the caspase-3 activity shows a significant overbalance
of blastocysts with high caspase-3 activity, regardless the stage of blastocyst development
and their origin. Thus, using excellent quality oocytes and sperm with reduced in vitro fertilizability
it was possible to some extent to overcome bull effect on embryo production.
