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 DraminskiTMestrus detector probe insertedinto the vagina on the first day of estrus. Estrogen and progesterone concentrations were measured in blood samples collected on the first day of estrususing the enzyme-linked immunosorbent assay (ELISA) method. Data on the correlation between ERVM scores and the levels of estrogen andprogesterone concentrations were analyzed using the Pearson correlation test. The results showed that the average ERVM score during the estrusphase was 192.9216.94 , and the average concentrations of estrogen and progesterone were 103.1344.86 pg/mL and 0.960.60 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 correlatedwith estrogen and progesterone concentrations.
