| Abstract: | A system was developed for measuring in vitro the electrical resistivity (ρ) of vaginal mucus samples collected throughout a complete oestrous cycle from three Hereford × Friesian cows. Measurements of intravaginal electrical resistance (Rv) and mucus electrical resistivity were made in six Hereford × Friesian cows throughout a complete normal oestrous cycle. Both Rν and ρ fluctuated during dioestrus and fell to a minimum value at oestrus. The decrease in ρ was larger than that of Rν. A significant correlation was found between Rν and ρ (P < 0.01; r = 0.56). |
