ASSESSING ELECTRICAL RESISTANCE OF VAGINAL MUCUS (ERVM) SCORES IN ESTRUS PHASE OF ACEH COWS AND THEIR ASSOCIATION WITH ESTROGEN AND PROGESTERONE LEVELS

This study aimed to determine the correlation between ERVM scores and the levels of estrogen and progesterone in Aceh cows during estrus. This study utilized 8 clinically healthy Aceh cows aged 3-5 years. ERVM scores were determined using a DraminskiTM estrus detector probe inserted into the vagina on the first day of estrus. Estrogen and progesterone concentrations were measured in blood samples collected on the first day of estrus using the enzyme-linked immunosorbent assay (ELISA) method. Data on the correlation between ERVM scores and the levels of estrogen and progesterone concentrations were analyzed using the Pearson correlation test. The results showed that the average ERVM score during the estrus phase was 192.92±16.94 Ω, and the average concentrations of estrogen and progesterone were 103.13±44.86 pg/mL and 0.96±0.60 ng/mL, respectively. Correlation analysis revealed that coefficient correlation (r) values between EVRM and estrogen was -0.607 and with progesterone was -0.149. In conclusion, the ERVM score in Aceh cattle indicates moderate estrus, and the ERVM score obtained in this study is negatively correlated with estrogen and progesterone concentrations.
