Abstract
The objectives of this study were to determine the prevalence of, and
risk factors for mastitis of cattle and the mean lactation number at
which mastitis is more frequent.
A retrospective based study was carried out in Khartoum and White
Nile States in two farms, designated as Farm A and Farm B. Farm A
practiced hand milking twice daily; while Farm B used mainly
machine milking, (with hand milking to lesser extent) three times a
day.
A convenient sample of 94 lactating cows in Farm A and 690 lactating
cows in Farm B was used for this study. A four years period data
(2005-2008) were collected for FarmA and two years period data
(2007-2008) for Farm B from health (mastitis), production and
reproduction records.
The data collected included number ofmastitis cases per day, lactation
number, daily milk production in litres, number of lactating cows and
type of milking used, including risk factors related to hygienic
measures and management practices. These data were analyzed using
SPSS software programme.
The results revealed that there was a high prevalence of mastitis
throughout the study area (34.4% inFarm A and 38.9% in Farm B).
Lack of appropriate hygienic measures and management practices
were reflected in the high prevalenceof mastitis inthe study area.

The mean lactation numbers at which mastitis was more frequent were
the third and second.
To indicate which of the milking techniques (machine and hand
milking) is a risk factor for bovine mastitis, odds ratiowas calculated
using a 2 X2 table. The odds ratio of 1.3 indicates that hand milking is
a risk factor for bovine mastitis,meaning that cows which are hand
milked are 1.3 times more likely to get mastitis than those milked with
machine.
Accordingly, it may be recommended that special care must be
directed towards cows at the third and the second lactations; and where
hand milking is practiced, application of rigorous hygienic measures
should be considered
