Thirty-two buffaloes at different periods of gestation were included. The buffaloes were palpated transrectally and transabdominal ultrasonography was applied to determine the pregnancy and fetal viability status. The accuracy, sensitivity, specificity, the positive and negative predictive value of transrectal palpation were 93.7, 100, 83.3, 90.9, and 100%, and for transrectal palpation were 78.1, 100, 58.8, 68.2, and 100%, respectively. The values of accuracy and specificity in the first trimester obtained by transabdominal ultrasonography were lower than those obtained by rectal palpation (66.6 vs. 94.4% and 62.5 vs. 90.9%), whereas the same values of accuracy and specificity were at second and third trimesters. Notwithstanding the values of the transrectal palpation and transabdominal ultrasonography sensitivity were 100% in the three trimesters of buffalo’s gestation. At the first trimester of gestation, transabdominal ultrasonography required more time in comparison to transrectal palpation to get the final decision. Conversely, transrectal palpation required more time than transabdominal ultrasonography to diagnose the pregnant buffalos which were at the second and third trimesters of gestation. The transabdominal ultrasonography pregnancy diagnosis in the third trimester was faster than at the second and first trimester, a highly significant (P<0.001) negative correlation was reported between the time required for pregnancy diagnosis and the gestation age. It can be concluded that the transabdominal is a practical approach of ultrasonography for pregnancy diagnosis and determination of fetal viability in buffalo cows especially at the second and third trimesters of gestation.  %U https://www.vetmedmosul.com/article_170052_8c54b4e54eab27dfb2f8ea6c0d78447a.pdf
