DeLaval voluntary milking system VMS
Operation
Maximum teat length
The maximum teat length that can be
handled by the teat preparation cup is 70
mm. An indication of a too long teat is that
water escapes from the top or at the holes
on the sides of the cup.
Keep udders free from long hair
Long hair on udders can make it difficult for
the image-interpreting software to locate
teats. In addition, straw can get stuck on
udders and impair the teat location further.
Cut the hair on the udders to avert this
problem. Teats shall always be kept free
from hair.
Fetch and start positions
Too long.
Within limits.
Failure or low performance when fetching or
attaching cups may be due to inaccurate
position programming. Re-determining the
positions may help. Good teat positions
(start positions) are best achieved when the
cow is due for milking.
Camera window
The camera window should be cleaned
manually and regularly. Ensure that the
instructions in the chapter "DeLaval
voluntary milking system VMS;
Maintenance" are followed.
Camera window
Also check that the automatic rinsing of the
camera window is carried out regularly.
