ABSTRACT
Mastitis treatment intends to shorten duration of infections, to minimaze
the frequency of new infections and to keep the presure of infectious agents
low. Supporting managemental efforts assure the success of therapy by reducing
the factors assisting mastitis. To give managing support to mastitis therapy and
therefore improve raw milk quality means: you should check the environmental
factors - correct the mistakes! The most important prophylactic and supporting
measures when dealing with herd sanitation are: housing and feeding well adapted
to the individual animal, competent milking with an hygienically and
functionally correct milking machine, consequent hygiene management, right
drying-up, culling of incurable cows just in time, avoiding mastitis by suckling
in heifers, buying proven and udder healthy animals only. Keep the withdrawal
times after treatment, check udder health in regular intervals and assure
yourself of therapeutical success. Innovative techniques in milking are
presented, methods are shown to check the hygiene status of the milking area and
to judge quality of milking itself.
Key words: mastitis therapy, managing support, quality of raw milk.

ABSTRACT
The relationship between milk yield, milkability and somatic cell count was
investigated with the aim to find a possible basis for selection of more
resistant cows to mastitis. In the herd of 60 Holstein - Friesian cows during 3
years milk yield (electronic flowmeter) amd milking time (stop watch) was
measured. Milkabilities were calculated and cell count were determined in milk
samples (Fossomatic). The following results were established: at low milk yield
and good milkability, cell count was the lowest (x = 205.000/ml); at high milk
yield and poor milkability, cell count was low (x = 233.000/ml); at high yield
and good milkability, cell count was higher (x = 260.000/ml) and, finally, at
low milk yield and poor milkability, cell count was the highest (x =
281.000/ml). The differences between groups were too small to suggest any final
conclusion.
Key words: milkability, milk yield, mastitis, cell count.

ABSTRACT
The somatic cell counts of ewes' milk were determined by the Fossomatic
method and compared with the bacteriological status of the mammary gland. Of 366
milk samples from uninfected udder halfs, 81.9% had SCC less than 250x103
cells/ml and 98.8% of 130 bacteriologically positive samples had a count higher
than 250x103 cells/ml. Of the examined milk samples 26.2% showed positive
bacteriology during the single sampling. The most frequent pathogens isolated
from the milk samples were coagulase-negative staphylococci. In contrast to
cows, in sheep this type of bacteria should be considered as pathogenic.
Considering our results, 250x103 cells/ml should be the optimal threshold value,
which could be regarded as the upper limit for normal SCC of ewes' milk.
Key words: sheep, mastitis, somatic cell counts.

ABSTRACT
According to our hygienic milk quality regolatory objectives bulk farm
milk somatic cell count must not on average exceed 500.000 cells/ml in three
months’ period. It is necessary to introduce permanent udder health status
control program to reach target values under 200.000 cells/ml. Program also
provides taking individual samples once a month for individual cow somatic cell
count which enables us to make number of udder health management decisions:
eliminationof factors which can influence elevated somatic cell count and are
not conected with mastitis, good screening for the identification of infected
cows in herd, taking measurements against decreased risk factors for infection
spread, ordering optimal treatment time especially for S. aureus
infections where the draying off cow treatment is more efficient, evaluation of
the response to the treatment and other measurements.
Key words: hygienic milk quality, subclinical mastitis, somatic cell count.
MILKING MACHINE AND MASTITIS

Language: English
ABSTRACT
The paper reports the results of different investigations done by
scientists of FG Milcherzeugung in the past. A short introduction about the
defence mechanisms of the teat against invasion of pathogens shows the
importance of the liner and its movement in mastitis prevention. Hamann'
s model of "pressure changes and mastitis" - slightly changed - serves
as starting point for discussion of the results of our investigations of
influence of vacuum fluctuations on liner movement, liner movement and
stripping, control of liner movement to decrease strippings without increasing
machine on time. The discussion is supplemented by results of investigations of
the role of milking systems in udderhealth of herds.
Key words: liner movement, strippings, milking systems and mastitis.
