Abstract:

The present study was carried out with the objective to detect embryonic mortality in a total of 142 cows inseminated at spontaneous estrus. The ultrasonographic scanning with trans-rectal probe using frequency of 7.0 MHz was carried out on day 28 to confirm pregnancy and re-examination on day 45 to assess the incidence of embryonic mortality under farm conditions. Out of 53 animals which exhibited non-return to estrus, 51 animals were having viable embryo with heart beat on day 45 post-insemination. Thus, incidence of embryonic mortality in the current investigation recorded was 3.77% (2/53). The embryonic heart beat on day 28 and 45 was recorded to be 177.94±2.16 and 190.28±2.77 beats per minute. The cytobrush sampling was also carried out on day 45 in two animals that suffered from embryonic mortality to rule out the specific or non-specific infectious cause of embryonic mortality, if any and no microbial cause of embryonic mortality was observed.
