Mastitis-inflammation of the udder-is one of the most important and costly problems in dairy farming. Subclinical mastitis is particularly dangerous, the milk looks normal and the udder or quarter affected appears healthy.
Subclinical mastitis will remain in this dormant state, but can develop at any stage into clinical mastitis, causing loss in milk production, and milk quality, and spreading infection to other cows in the herd..
The Draminski Electronics Mastitis Detector consists of a measurement cup with electrodes, electronic unit with LCD panel, handle containing a standard 9 volt battery and a switch.
The display indicates the correct work of the device. First check-out the detector before the milk sampling, when it is dry and clean. After pressing the button, four dashes are displayed in the corners of the face indicating the device is ready to work. Now the consecutive milk quarters can be measured. Blinking dashes indicate, which quarter is being tested. To take measurement , the milk is stripped in and the switch pressed.
After the switch is pressed, the flashing dashes disappear, and result will come up in specific numbers. Next the flashing dashes will appear in the next column. Similarly all other measurement from the next quarters will be done.
Additionally the display will show when battery runs out, a flashing battery symbol signals that the battery is to be replaced. 10 units is the lowest result possible whereas the measurement range is 10-990 units. After the level of 990 units has been exceeded dashes are shown on the display(the same symbol as in the case when the device tried in the "empty air".
The measurement range of mastitis detector exceeds the maximum detector exceeds the maximum conductivity value of tested milk considerably. It means that actually it will never be exceeded.
Please follow the instructions given below when taking measurement ALWAYS USE FIRST TEAT OF THE MILK, BEFORE THE TEAT CUPS ARE PUT ON, TO OBTAIN YOUR READING each quarter should be examined separately.
Press the ON/OFF switch and place the cup under the teat A. Strip the milk directly into the cup, enough to comfortably cover the probes.
After about 1 second press the switch to turn the detector on-the result will be displaced. For example
Discard milk into bucket, then press turn on the device, the dashes will start flashing again for the next quarter, proceed as before, and for each the remaining quarters.
After you have sampled four quarters, they will all be shown in the display window
Press the button once again to see which quarter may be under the threat of subclinical mastitis. Now the difference between particular quarters are displayed. 10 0 60 0 After reading out the results and the difference between the quarters the user should make an interpretation of results following the rules given in the next chapter.
After the results have been viewed, the detector should be thoroughly rinsed out in order to avoid contamination of the next set of readings
It is possible to examine the next cow at once. You only have to press the button for a short time to turn on the detector. All previous read- outs will disappear. The detector is now ready for next measurements.
The detector turns off if the button is kept pressed longer than 3 seconds. When finished press the ON/OFF switch.
If no button is pressed during 30 seconds time the instrument turns off automatically to conserve battery power.
INTERPRETATION OF RESULTS :
Reading below 250 units :
This is clear indication of a rapid increase in the severity of infection as subclinical or impending clinical mastitis is present.
Reading above 300 units :
The milk sample is of higher quality. Most commonly the read-out are placed in the range 330-360 units, and the incidence of subclinical mastitis is very low. Among young milk cows (1-2 lactations) the readings will generally average of 390 units whereas the old cows will average 320.
Reading between 250- 300 units :
Should trigger warning signals, to the operator, and regular monitoring is necessary, to check the figures do not change. If the figures in this category are only in one quarter, and are at least 50 points behind, the lowest of the other quarters, then a mastitis infection is present in the low numbered quarter and should be treated.

1. Can the Mastitis detector measure tank milk?
No,it cannot. 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.
2. 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 do 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.
3. Is it possible to check if the instrument operates correctly?
turn on the instrument with an empty measuring cup ("0 1" should appear on the screen)
prepare solutions of kitchen salt at different concentrations and check the results shown by the instrument (the results should decrease with the higher salt concentration)
remember that the electrodes should be clean during the tests
do not perform measurements when LO BAT (low battery) appears on the display; in such a case replace the battery.
4. 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.
5. 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 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.
6. How is it possible to use the measurement of milk resistance to test udder health?
The infection is the most common reason which triggers off mastitis. The inflammation has different stages, starting from a subclinical stage without symptoms and ending with an acute clinical form with visible symptoms. From the beginning the bacterial infection damages the udder tissues and therefore the transfer of ions, especially sodium and chlorine ones, is increased from blood into milk. In such a situation the concentrations of these ions in milk significantly increase, resulting in easier current flow. The electrical resistance of milk decreases in the infected udder quarter. And these changes in resistance are detected by the Mastitis Detector.
