electronic estrous detector:
• Makes it easier to determine an optimum mating
time for females with atypical estrous cycles
• It enables the user to detect an asymptomatic
estrous period (the so called silent heat)
• Makes insemination more effective.
• Improves the economic performance of farms.
one of the most important elements of reproduction
management in livestock, is the detection of estrous
period, which is due to the close dependence of
female insemination effectiveness on the accurate
time of performing the insemination.
Research shows that there is a high rate of
undetected estrous periods in breeding practice.
Estrous usually proceeds very dynamically, which
can make it difficult for all animal breeders to
detect it regularly. Estrous and ovulation periods
are short, so it's easy to overlook them in the case of
infrequent or careless observations.

Therefore, various biotechnical methods of estrous
observation have been investigated, one of them
being the measurement of electrical resistance of
the vaginal mucus during estrous.
Knowledge of physiology and in particular
changes occurring
organs, demonstrated that changes in the ovaries
are accompanied by changes in the electrical
resistance of the animal's vaginal mucus. It is worth
emphasising that close relationships were also
noted between changes in electrical resistance of
the vaginal mucus and the level of hormones.
All the above phenomena and relationships related
to changes in vaginal mucus resistance were
used by DRAMIŃSKI to design an ELECTRONIC
estrous detector
