ELECTRONIC DETECTOR OF SUBCLINICAL MASTITIS IN COWS:
•En bles the r pid detection of subclinic l m stitis in l rge number of cows, directly
in the cowhouse just before milking. It llows ppropri te preventive steps to be
m de th t could prevent the dise se from its tr nsition into clinic l condition.
•H s mobilising effect on breeders nd the personnel t king c re of nim ls.
•Improves the economic results of stock f rming.
M stitis - infl mm tion of the udder - is one of the most import nt nd costly problems in
d iry f rming.
Subclinic l st tes of m stitis re p rticul rly d ngerous. In this st te, milk looks norm l
nd the udder or qu rter ffected ppe rs he lthy. Subclinic l m stitis c n r pidly
become clinic l m stitis or c n continue t subclinic l levels, ffecting milk production,
milk qu lity, nd spre ding infection to other cows in the herd.

Before st rting your me surement the following should be done:
1. Check the work of the detector in the ‘open ir’ ensuring th t the b ttery is fully
ch rged.
2. Ensure th t the electrodes in the cups re cle n. Cont min tion of electrodes with
skin-oil from h ndling or ex min tion while on displ y in stores nd/or dried milk-f t c n
result in incorrect (high) re dings. If required, wipe the electrodes with methyl ted spirits
on cle n cloth or tissue, or simil rly with kitchen detergent nd rinse off.
) prep re solution – pour pinch of s lt into gl ss of w ter (of room temper ture)
dissolving it completely.
b) fill out the cups with the solution nd re d the result (it depends on the solution
concentr tion.
c) Pour out the solution into the gl ss nd cle n thoroughly the electrodes with t mpon
moisten with the liquid for w shing the dishes. Rinse the cups under the t p sh king the
w ter rem ining off.
d) pour the solution into the cups g in nd re d the result. If there is rem rk ble drop
in the result in comp rison to the previous me surement it me ns the electrodes were
co ted with f t.
e) the best is to repe t cle ning procedures until it is sure th t the results do not ch nge
ny more. The l tter me ns the electrodes re now cle n. Note th t even touching the
electrode with finger m y cont min te the electrodes.
3. Prep re bucket full of w rm w ter for rinsing the cup fter e ch me surement.
Addition lly, nother empty bucket will be useful for pouring out the milk from the cup
fter the me surement. To comply with the hygienic regul tions you must not pour the
milk out on the cowshed bedding.
MEASUREMENTS
ALLWAYS THE FIRST SQUIRTS OF MILK SHOULD BE MEASURED that are squirted
directly
to the measurement cup. Each quarter should e examined separately.

11
Measurements are made in the following way:
Model: 4x4Q MAST
1. Pl ce the cups under te ts A, B, C, D nd squirt the first stre ms of milk to fill the cups
(minimum volume – pprox. 1 cm from the top edge of the cup). Milk should be squirt
s f st s possible.
2. Then press the on/off switch. The device will count down three seconds
3. Results for e ch qu rter will be displ yed, for ex mple:

switch g in to displ y the differences between the individu l qu rters, in rel tion to the
highest result obt ined, for ex mple:
.
After re ding the results nd differences for individu l qu rters, they should be
interpreted ccording to the principles presented in the following section.
5. Pour the milk into the prep red bucket (to the l st drop). In the c se of milk yield h ll,
the milk m y be disc rded into the c tch b sin.
6. After cow h s been tested, the device should be rinsed: cups should be immersed in
w ter nd vigorously moved to remove ny residues of milk.
7. Another cow m y be tested immedi tely fter rinsing the me suring cups nd short
press of the switch. All the results will be er sed nd re diness for nother test will be
displ yed.

Note! Rinsing should also e completed after testing a quarter in which a
su clinical condition has een detected. That way, residues of milk from that
sample will not affect the measurement of another quarter.
After cow h s been tested it is recommended to note the principle conclusion or
m rk it with symbol. Is the udder completely he lthy, or is there suspicion of the
dise se.
SYSTEMATIC UDDER EXAMINATION IS AN IMPROTANT ELEMENT OF PREVENTION.
Preventing is cheaper than treating
14
IT IS NECESSARY TO EVALUATE RESULTS ACCORDING TO TWO CRITERIA:
1. What is the value o tained from the tests of quarters and is it typical for the
tested cow (individual evaluation considering the age of a cow),
2. What are the differences etween the quarters in a tested cow.
Regarding item 1 :
Readings elow 250 units:
Indic te cle r subclinic l infl mm tion of qu rter of n udder, or high risk of
tr nsition into n cute condition (which m y be r pid).
Readings over 300 units:
good condition of qu rter of n udder. Usu lly results f ll within the r nge of
330-360 units. In young nd he lthy cows results m y be higher (370-400), nd
in older cows they m y be lower (300-320).
Readings from 250 to 300 units:
tr nsition l st te between subclinic l m stitis nd norm l condition. Due to
physiologic l differences it is difficult to define strict border v lue, the
exceeding of which indic tes the dise se of qu rter of n udder.
In some cows re dout between 250 nd 300 units is considered norm l,
especi lly if no higher v lues re obt ined from th t individu l cow. In th t c se
qu rter should be considered norm l. However, if in cow for which norm l
v lues exceeded 300 units sudden drop is observed to the level of 250 - 300
units, the cow should be considered t risk of m stitis.
Regarding item 2 :
A difference exceeding 40 - 50 units etween the highest and the lowest result
o tained for quarters in a tested cow indicates the onset of su clinical mastitis. It
is necessary to examine the cow systematically efore each milk yield, and
o serve it for the progression of the disease (a further drop of results for the
suspected quarter). Moreover, particular care and increased hygiene efore and
after milk yield are necessary.
SAMPLE INTERPRETATIONS:

INTERPRETATION OF RESULTS

quarter A = 310
quarter B = 290 result below 300, but the m ximum difference is only 20
units.
quarter C = 300
quarter D = 300
Important factors affecting the level of results o tained from the tests of healthy
cows:
1. nim l’s ge,
2. breed (the bove interpret tion is v lid for bl ck nd white + hf cows; Jersey cows
would h ve re douts t higher level),
3. individu l properties of nim ls (e.g. f t content in milk),
4. nutrition – composition of dose or its lter tion m y influence results,
5. physiologic l condition (e.g. tests should be discontinued during he t period),
6. met bolic bnorm lities ( cidosis or lk losis) m y be di gnosed b sed on
surprising signific nt incre se or decre se of results for ll cows in herd.
Note! Only the systematic control of cows allows the proper and effective use
of the detector.
The detector may not e used for the testing of quarters clearly inflamed and
with significant changes in milk. In those cases the correct interpretation of
results is impossi le. The method of the measurement of changes in milk
impedance may e used for the detection of the early stages of Mastitis
subclinica.
If the b ttery icon fl shes for some time or perm nently, or LO BAT symbol is
displ yed, the b ttery needs to be immedi tely repl ced. Results obt ined with device
indic ting low b ttery re not reli ble nd c nnot be properly interpreted. B ttery
repl cement procedure.
1. Unscrew both screws fixing the cover to the h ndle.
2. Slide the b ttery from the h ndle nd disconnect it from the c tch
3. Inst ll new b ttery nd slide it into the h ndle.
4. Screw both screws in to fix the cover. T ke c re to ensure even
compression of g sket.
We recommend using lk line b tteries or high c p city regul r b tteries of renowned

Cleaning of electrodes
•Dirty, greasy electrodes c use f lse results to be given by the device (too high).
Also the presence of other liquids th n milk on the electrodes m y c use f lse results
(e.g. too low). Therefore m int ining the cle nliness of the electrodes nd the whole
device is of utter import nce.
Degre sing (cle ning) of electrodes should be performed before e ch session of
me surements.
Commonly used detergents re used for cle ning (w shing-up liquid, w shing
powder). In those regions where the t p w ter is h rd (high iron, c lcium, phosphorus
s lts content), electrode cle ning is p rticul rly import nt.
After degre sing, me suring cup should be thoroughly rinsed with running w ter.
•In the case of a normal (excessively high) readouts, degrease electrodes first.
•Gener l principles of hygiene should be observed when m king me surements.
•The housing of the device m y be cle ned with d mp cloth, using mild detergents.
The procedure should be completed directly fter the end of session of tests. Do
not use hot or oiling water for cleaning.
•The device should be stored in dry pl ce, optim lly t room temper ture.
•After the end of the w rr nty period the M nuf cturer offers m inten nce nd
service of the device t fee.
•Considering v lid zoo-s nit ry requirements, lending the device to other f rmers is
not recommended.
