1. How does the estrous detector work?

The estrous detector picks up electrical resistance in the vaginal mucus, if there is a rise in resistance it indicates ovulation. The detector is inserted into the vagina, testing should be done once or twice a day for several successive days for fail safe ovulation detection.


2. Does the way of using the estrous detector affect the readings?

Yes, it does. The angle at which the probe is introduced into the vagina as well as the probe length influence the readings. For that reason we recommend to perform measurements always in the same or similar manner.


3. Which animals can the Estrous Detector be used for?

The Draminski estrous detectors can be used for the following animals:

  • for cows and mares
  • for pigs
  • for ewes
  • for bitches

These detectors differ mainly with the probe size and location. The user should remember that the test principle is the same in all versions; however, received measurements and interpretations are different for each species and differ for ages of the female.


4. How can I check if my detector operates properly?

  • Ensure the electrodes are clean by gently rubbing with vim, rinsing and drying
  • Mix an amount of salt in a glass of water
  • Mix a second amount of salt in another glass of water
  • Test glass 1 for a reading. Clean probe
  • Test glass 2 for a reading. Clean probe
  • Test glass 1 and 2 again. If the readings for each salt solution are constant the machine is in order.



1. What is the difference between the Sonofarm Mini and the Animalprofi?

1. I would like to consult a given diagnosis with a vet. What can I do?

The Animalprofi Scanner has an internal memory of 200 images. After stopping an image (the START/STOP button) you can save the image in the memory (the Main Menu >Memory>, submenu >Save). In addition, you can describe the image with an animal number and fill in the day of possible pregnancy (date and time will be added automatically). Consequently, you can save important images and consult them, for example, with a vet. Additionally, the scanner is equipped with a possibility to transmit images into a PC. This function allows to save an infinite number of images in your PC and to e-mail or print them, if necessary.

2. Can I use the scanner in small and large animals?

Yes, you can. The Animalprofi Scanner is intended to examine all animals. The user can choose a probe they want the scanner to be equipped with. The abdominal probe is indicated for small animals (pigs, sheep, goats, dogs and cats). The rectal probe is indicated for large animals (cows and mares). The scanner automatically recognizes the type of a probe.

3. Is it possible to measure backfat thickness in pigs?

Yes, it is possible with an abdominal probe. No other probes or additional devices are necessary. When you place the probe on the back of a pig (C7 spot) and locate a correct image of backfat and muscles, freeze the image pressing the STOP/START button. Then open the main menu, select the option >Measure> and then >Length in the submenu. When a red cursor appears, place it in the upper border of the backfat visible in the image and then press the OK button. Then a green cursor appears which should be moved with arrows to the lower border of the backfat. On the right side of the screen a box will appear with the information about the distance between these two cursors (in millimetres) which indicates the backfat thickness.

4. What is the difference between the sector probe and the linear probe?

Both probes are used internally. The linear probe is mostly used for horses as it gives you a clearer image, and a more detailed image. It can also be used on cattle. The sector probe is easier to use as it gives you a wider image of 180° and the linear probe gives you a linear image on the scanner.



1. Is it possible to count the number of somatic cells (somatic cell count) based on the measurement of the electrical resistance of milk?

It is impossible! The instruments measuring how the electricity is conducted in milk and does not count the somatic cells in a direct way. The changes in the resistance level and the number of cells are not directly interconnected. It should be acknowledged that decreasing resistance indicates a developing infection. It is a basic rule which is used to evaluate the health condition of the udder. However, the number of somatic cells reflects the reaction of the immunological system which is specific for each organism. The reaction of this system is a result of the level of stress which a cow is suffering from and good or impaired readiness to fight the infection. Such readiness determines the number of cells in milk and decides when the number of cells reaches a high level after the infection. The measurement of resistance with a manual instrument is a practical method to monitor the health of the udder quarters; however, additional analyses are always necessary in order to make a precise diagnosis and start an efficient treatment in case of disease development.


2. Which stage of udder disease can be checked with the Mastitis Detector?

The most important thing to be aware of is the fact that the DRAMIƃSKI Mastitis Detector measures subclinical conditions of the udder inflammation. It means that with this instrument you can prevent the disease and not allow for clinical development of mastitis. The Mastitis Detector does not detect a clinical form of the disease, so it does not measure the number of somatic cells.


3. What are the main recommendations regarding the use of the Mastitis Detector?

  • During the tests a measuring cup should be filled completely (up to a line in the upper edge). It turned out during experiments that the volume of 15 ml of milk is necessary in order to perform measurements correctly.
  • The instrument should be precisely cleaned before the onset of tests. If the electrodes are grease-stained, the results will be incorrect. The best cleansing agent is typical washing powder or liquid. CAUTION! Do not use abrasive detergents! They may damage the instrument permanently!
  • Do not use very cold or very hot water.
  • Do not store the instrument at the temperature below 0°C.


4. Can the Mastitis detector measure tank milk?

No, it can't. Tank milk shows completely different values from the milk from a single cow. Therefore, the interpretation of results presented by the manufacturer can be used only for individual cows; it cannot be used for tank milk.



1. What should I remember while using the Moisture Meter?

  • In order to achieve the most reliable readings, you have to perform three measurements of one grain sample and then average them
  • The purity of a testing sample has an influence on the accuracy of readings. The sample should be free of chaff, dirt and other impurities.
  • The way of filling the measurement compartment is important and affects the accuracy of results:
  • While pouring the grain the slide should be pulled out with a decisive regular movement over a period of about one second.
  • The upper edges of the measurement chamber must be completely covered with grain after its filling.
  • Ensure the temperature of the instrument is similar to the temperature of a sample (the sensor reacts with a slight delay)


2. Can I calibrate my Grain Moisture Meter with my closest Co-op, Supply Depo, Grain Silo or Customer?

Yes you can. Get a sample from the Co-op and get the calibration with their moisture meter. It is possible to then calibrate your Grain Moisture meter to the same as the Co-op.

3. How many different grains can the Grain Moisture Meter test?

The Grain Moisture Meter is able to test 30 different species of grain.
