Breeders often experience problems when detecting estrus so that cows fail to get pregnant and repeat breeding resulting in losses for farmers due to reduced livestock production. Reproduction productivity improvement can be achieved during estrus cycle with accurate estrus detection to determine the the proper period to perform insemination. This study aims to determine the accuracy of Electrical Resistance of Vaginal Mucus (ERVM) method in detecting estrus in Aceh cattle. In this study, six Aceh cattle aged, 3-5 years old with body weight of 150-250 kg and clinically healthy were used. Before estrus synchronization, rectal palpation was performed to determine reproductive status whether in the follicular phase or luteal phase. All Aceh cattle were synchronized using 5 ml of prostaglandin F2 alpha (PGF2α) intramuscularly with a single injection. Detection of estrus using the ERVM measurement method was carried out using the Draminski estrus detector thrice. The results of estrus examination with ERVM were confirmed by the presence of cervical mucus secretion (gold standard) after synchronization. The data obtained from the ERVM measurement were calculated for the sensitivity, specificity, and accuracy values. The results of this study indicated that the average value of ERVM in Aceh cattle during estrus is 197.22±5.34 ∧, while in not estrus Aceh cattle was 313.33±29.29 ∧, sensitivity (100%), specificity (100%) and accuracy (100%). Based on the results of the study, it can be concluded that estrus detection using the ERVM measurement method has a high level of accuracy, so that the use of this method can be recommended in estrus diagnosis/detection for farmers to perform artificial insemination in Aceh cattle. © 2024 Author(s).
