Název v původním jazyce

Early oocyte penetration can predict the efficiency of bovine embryo production in vitro

Popis výsledku v původním jazyce

The aim of this work was to characterize oocyte fertilization and embryo cleavage in nine AI bulls to find parameters suitable for prediction of in vitro fertility. According to the blastocysts rate, they were categorized as high, medium and low productive (HP, MP and LP) bulls. For these categories, oocyte penetration and fertilization, and embryo cleavage and fast cleavage were assessed. The penetration rate was significantly higher for HP bulls than for MP and LP bulls (67.9 vs. 50.3 and 33.1%). Thesyngamy rate was significantly higher for HP bulls than for MP and LP bulls (21.4 vs. 10.2 and 5.7%). On the contrary, no significant differences in fertilization rates were found among HP, MP and LP bulls. The cleavage rate was significantly higher forHP than LP bulls (82.4 vs. 74.4%). The fast cleavage rate was significantly higher for both HP and MP bulls compared with LP bulls (82.1 and 84.7 vs. 73.5%) A strong correlation was found between blastocyst production and the evaluated pa
