Abstract

We evaluated the "in vitro" blastocyst rate production using bovine sexed semen. Semen from three bulls was used to verify the individual's semen variation, cleavage rates and embryo production. In this study, we employed reproductive biotechnologies, computer analysis of post-thawed semen and fluorescent probes for sperm cells integrity analysis (plasma membrane, acrosome membrane and mitochondrial potential). A total of 959 oocysts went through in vitro maturation steps for in vitro fertilization and cultivation, being 473 with sexed semen and 486 with conventional semen. The cleavage rate was observed in blastocysts on D2 and D7. Data were analyzed by SPSS 16.0 software using analysis of variance (ANOVA), Student's t-test was used to detect differences between groups, and chi-square analysis for in vitro production results (P <0.05 ). The results differed between conventional (31.06%) and sexed semen (21.10%) in the obtainment of blastocyst. When the blastocyst production was individually compared in sexed semen samples (27.69%, 17.93% and 25.56%, bulls 1, 2 and 3, respectively) we verified T2
