Effects of various concentrations of BADGP on preimplantation development of pig parthenogenetically activated diploids. Diploids were cultured in PZM3 with 0 (C, control; D, DMSO as vehicle control), 1.0, 2.0 and 4.0 mM BADGP. Trials were repeated at least three times in each experimental group, and the total numbers of cultured diploids for the analysis were 48, 28, 28, 28 and 27 for the control, vehicle control and 1.0, 2.0 and 4.0 mM BADGP groups, respectively. There were no significant differences in the proportion of diploids that developed to the most advanced stage or in the proportions of diploids that developed normally at each observation point among the experimental groups.
