Gambaran ultrasonografi organ reproduksi pasca inseminasi buatan pada sapi aceh abstrak banyak faktor yang dapat memengaruhi keberhasilan reproduksi dan produktivitas sapi. oleh karena itu, analisis kondisi organ reproduksi sapi pasca inseminasi buatan (ib) menjadi penting, tidak hanya untuk mendeteksi kebuntingan tetapi juga untuk mengidentifikasi penyebab kegagalan fertilisasi. penelitian ini bertujuan untuk menggambarkan kondisi organ reproduksi sapi aceh pasca ib dan mengidentifikasi penyebab kegagalan fertilisasi menggunakan ultrasonografi transrektal. penelitian menggunakan 6 ekor sapi aceh. pemeriksaan ultrasonografi dilakukan pada hari ke-25 dan ke-35 pasca ib untuk mengamati ketebalan endometrium, korpus luteum (cl), dan keberadaan embrio. hasil penelitian menunjukkan 2 ekor sapi 1 dan sapi 2 terdeteksi bunting, yang ditandai dengan keberadaan vesikel embrionik dan cl pada hari ke-25 dan ke-35. sementara itu, 1 ekor sapi (sapi 3) menunjukkan vesikel embrionik dan cl pada hari ke-25 tetapi tidak teramati lagi pada hari ke-35. tiga ekor sapi (4,5 dan 6) lainnya tidak terdeteksi bunting. rata-rata ukuran cl pada sapi 1 bunting adalah 1,20 ± 0,00 cm (hari ke-25) dan 1,30 ± 0,00 cm (hari ke-35), lebih besar dibandingkan sapi 2 bunting (0,90 ± 0,14 cm dan 1,00 ± 0,00 cm). rata-rata diameter endometrium pada sapi 1 bunting adalah 2,25 ± 0,14 cm (hari ke-25) dan 4,20 ± 0,21 cm (hari ke-35), lebih besar dibandingkan sapi 2 bunting (1,10 ± 0,28 cm dan 1,95 ± 0,56 cm) serta sapi 3 tidak bunting (1,15 ± 0,05 cm dan 2,45 ± 0,26 cm). kesimpulan, terdapat perbedaan diameter ketebalan dinding uterus dan cl antara sapi aceh bunting dengan sapi tidak bunting. hasil pemeriksaan sonografi organ reproduksi, kegagalan fertilisasi pada sapi aceh dapat disebabkan adanya kematian embrio dini, endometritis, kista dan mismanajemen. kata kunci: sapi aceh, endometrium, inseminasi buatan, fertilisasi, ultrasonografi transrektal.

ULTRASONOGRAPHIC IMAGING OF REPRODUCTIVE ORGANS POST ARTIFICIAL INSEMINATION IN ACEH COWS ABSTRACT Various factors influence reproductive success and productivity in cattle. Therefore, evaluating the condition of reproductive organs post-artificial insemination (AI) is crucial, not only for pregnancy detection but also for identifying potential causes of fertilization failure. This study aims to assess the reproductive organ status of Aceh cows following AI and determine factors contributing to fertilization failure using transrectal ultrasonography. Six Aceh cows were examined using ultrasonography on days 25 and 35 post-AI to assess endometrial thickness, corpus luteum (CL) development, and the presence of embryonic structures. The results indicated that two cows (Cow 1 and Cow 2) were confirmed pregnant, as evidenced by the presence of embryonic vesicles and CL on both examination days. One cow (Cow 3) exhibited embryonic vesicles and CL on day 25, but these structures were not observed on day 35, suggesting early embryonic loss. The remaining three cows (Cows 4, 5, and 6) were not diagnosed as pregnant. The mean CL diameter in pregnant Cow 1 was 1.20 ± 0.00 cm on day 25 and increased to 1.30 ± 0.00 cm on day 35, which was larger than that of pregnant Cow 2 (0.90 ± 0.14 cm and 1.00 ± 0.00 cm, respectively). Similarly, the average endometrial thickness in pregnant Cow 1 was 2.25 ± 0.14 cm on day 25 and increased to 4.20 ± 0.21 cm on day 35, which was greater than that observed in pregnant Cow 2 (1.10 ± 0.28 cm and 1.95 ± 0.56 cm) and non-pregnant Cow 3 (1.15 ± 0.05 cm and 2.45 ± 0.26 cm). In conclusion, variations in uterine wall thickness and CL size were observed between pregnant and non-pregnant Aceh cows. Ultrasonographic findings suggest that fertilization failure in Aceh cows may be attributed to early embryonic death, endometritis, cyst, and suboptimal management practices.
