BEITESHUANG Livestock Estrus & Ovulation Detector

The BEITESHUANG Livestock Estrus & Ovulation Detector is a portable electronic reproductive-management instrument designed for cattle, mares and donkeys. It helps breeding technicians monitor physiological changes associated with the estrous cycle and identify a suitable time for mating or artificial insemination.

Model BTS-NP measures changes in the electrical resistance of vaginal mucus through a smooth probe with integrated electrodes. Results are displayed digitally on an approximately 2.6-inch LCD screen, allowing repeated measurements to be compared during the estrous cycle.

• Electrical Resistance Measurement: Detects changes in vaginal mucus associated with different stages of the estrous cycle.
• Fast Automatic Test: A measurement can be completed within approximately 3 seconds.
• 2.6-Inch LCD Display: Large digital display provides clear and direct reading of measurement data.
• Smooth Rounded Probe: Curved and polished probe design supports controlled insertion and helps reduce unnecessary tissue irritation.
• Water-Resistant Body: Protected housing and switch design are suitable for routine livestock breeding environments.
• Portable Battery Operation: Powered by one standard 9V 6F22 battery for convenient farm and field use.
• Lightweight Design: Approx. 300 g net weight makes the instrument easy to carry between animals and breeding areas.
• Multiple Species: Suitable for reproductive monitoring in cattle, mares and donkeys when species-specific interpretation is used.
• Breeding Timing Support: Helps technicians identify estrus trends and select an appropriate time for mating or artificial insemination.

Changes in reproductive hormones during the estrous cycle alter the composition and electrical characteristics of vaginal mucus. The electrodes at the probe tip measure these changes and the instrument converts them into a numerical reading.

Repeated measurements are compared over time to identify the characteristic decline and subsequent rise associated with estrus progression. The device is therefore a reproductive-management aid rather than a direct visual confirmation of ovulation, and readings should be interpreted together with animal history, behavioral signs and professional breeding practice.

• Install a fresh 9V 6F22 battery and confirm that the LCD operates normally before use.
• Clean and disinfect the probe thoroughly before every animal measurement.
• Clean visible manure, hair and contamination from the external genital area before insertion.
• Insert and position the probe gently according to the operating instructions and species-specific veterinary technique.
• Take readings from a consistent measuring position to improve comparability between measurements.
• Avoid immediate repeated testing after manipulating the vaginal mucus; allow sufficient recovery time according to the operating protocol.
• Thoroughly clean and disinfect the probe before moving to another animal to reduce cross-contamination risk.
• Do not clean the instrument with boiling or excessively hot water.
• Keep electrodes free from grease, urine, salts and other residues that may affect readings.
• Replace the battery when the low-battery indication appears on the display.
• Store the clean and dry instrument at room temperature in a protected location.

Q: What does this livestock estrus detector measure?
It measures changes in the electrical resistance of vaginal mucus that occur during the reproductive cycle.

Q: Can the detector directly confirm ovulation?
It is primarily a timing aid that identifies characteristic changes associated with estrus and approaching breeding time. It does not directly image the ovary or replace ultrasound examination.

Q: How fast is one measurement?
The BTS-NP completes an automatic reading within approximately 3 seconds.

Q: What is the measurement range?
The manufacturer's displayed measurement range is 10 to 1990.

Q: How are cattle readings interpreted?
The manufacturer's reference indicates that cattle readings are generally above 300 outside estrus, decline during estrus and may fall below 200 before rising again. Trends over repeated measurements are more useful than relying on a single value.

Q: Are the reference values the same for mares?
No. The manufacturer's reference indicates a different pattern for mares, with values commonly above 400 outside estrus and falling below approximately 300 during estrus. Species-specific interpretation should always be used.

Q: Can the same numerical thresholds be used for donkeys?
A specific donkey threshold is not provided in the current product information. Readings should therefore be interpreted using repeated individual measurements and professional reproductive guidance rather than applying cattle values directly.

Q: Why must the probe be disinfected between animals?
Because the probe contacts vaginal mucosa, inadequate cleaning can mechanically transfer contamination or infectious material between animals.

Q: Is the device suitable for commercial breeding programs?
Yes. Its portable design, rapid measurement and digital display make it useful as an additional reproductive-management tool for cattle farms, equine breeding facilities and artificial insemination services.
