초록

This study assessed the incidence of embryo and fetal los folowing early pregnancy diagnosis usingultrasonography in dairy cows. A positive pregnancy was a recognition of the vesicle, embryo or fetus by ultra-sonography. Seven hundreds and two pregnancies determined by ultrasonography folowing artificial insemination weredivided into three groups according to the number of days diagnosed pregnant: early A group (27 to 40 days, n = 143),early B group (41 to 50 days, n = 172), or standard group (51 to 70 days, n = 387). Following a positive pregnancydiagnosis, embryo or fetal loss included all cows with observed abortions and cows found open after the positivepregnancy diagnosis. The incidence rate of embryo or fetal los within 7 days after pregnancy diagnosis was 1.4,0.6 and 0.3% for the early A, early B, and standard groups, respectively (P. 0.05). The incidence of the embryoor fetal loss during 8 to 30 days after pregnancy diagnosis did not differ (P. 0.05) among the early A (0%), earlyB (1.2%), and standard groups (1.0%). Furthermore, the cumulative incidence of the embryo or fetal los before calvingdid not difer (P. 0.05) among the early A (9.8%), early B (9.3%), and standard groups (5.9%). These results indicatethat early pregnancy diagnosis using ultrasonography does not increase the risk of embryo and fetal los comparedwith that of routine pregnancy diagnosis in dairy cows.
