Maintenance an calibration
The following points are important to sustain
correct dosing of etergents. Note that
these two tasks should be performed by an
authorised DeLaval service engineer.
• The tubes in the peristaltic pumps should
be replaced at least two times a year.
• The dosing volume (P6-P8) of the
detergent pumps should be checked
every third month. The dosing capacity
(P32-P34) may need to be adjusted.
Starting cleaning or rinsing
from the touch screen
Note: Any ongoing backflush process must
first be finished before cleaning or rinsing
can be started.
1. Ensure that the milking station is in

Fig. 9: Progesterone level during the heat cycle.
A: Progesterone (ng/ml)
B: Days from the first heat
C: Heat alarm
Progesterone is a reproductive hormone pro-
duced by the ovaries and possible to detect in
milk. The concentration of progesterone increa-
ses and decreases according to a cyclic pattern.
By taking repeated samples from a cow during
the lactation, it is possible to detect heat, preg-
nancy and fertility problems like prolonged post-
partum anoestrus, follicular cyst, and luteal cyst.
The progesterone level in blood and milk always
drops before a cow goes into heat. Conse-
quently, a heat alarm is triggered when the pro-
gesterone level falls below a certain threshold (5
ng/ml). This indicates that the cow will be in heat
