dc.descriptionThe objective of this study was to evaluate the performance of using female sexed versus conventional semen for embryo production and pregnancies, as well as verify the impact of in vitro fertilization (IVF) and the sires used on the predicted transmitting ability (PTA) for milk production (PTA_MP), reliability (REL), and inbreeding coefficient (F) values in Red Sindhi dairy cattle. Data from four sequential IVF, pregnancies, and animals born at the Center of Technology for Zebu Dairy Breeds from Embrapa Cerrados-DF were analyzed. The first generation consisted of 22 embryo donor females and the second generation included 61 offspring generated by IVF using semen from seven different bulls. Embryo and pregnancy rates between sexed and conventional semen were analyzed using the chi-square test, and parameters in both generations were compared using the T-test (p<0.05) and Pearson correlations.
