الملخص

The objectives of this study were to determine the prevalence of, andrisk factors for mastitis of cattle and the mean lactation number atwhich mastitis is more frequent.A retrospective based study was carried out in Khartoum and WhiteNile States in two farms, designated as Farm A and Farm B. Farm Apracticed hand milking twice daily; while Farm B used mainlymachine milking, (with hand milking to lesser extent) three times aday.A convenient sample of 94 lactating cows in Farm A and 690 lactatingcows 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 andreproduction records.The data collected included number ofmastitis cases per day, lactationnumber, daily milk production in litres, number of lactating cows andtype of milking used, including risk factors related to hygienicmeasures and management practices. These data were analyzed usingSPSS software programme.The results revealed that there was a high prevalence of mastitisthroughout the study area (34.4% inFarm A and 38.9% in Farm B).Lack of appropriate hygienic measures and management practiceswere reflected in the high prevalenceof mastitis inthe study area.viiiThe mean lactation numbers at which mastitis was more frequent werethe third and second.To indicate which of the milking techniques (machine and handmilking) is a risk factor for bovine mastitis, odds ratiowas calculatedusing a 2 X2 table. The odds ratio of 1.3 indicates that hand milking isa risk factor for bovine mastitis,meaning that cows which are handmilked are 1.3 times more likely to get mastitis than those milked withmachine.Accordingly, it may be recommended that special care must bedirected towards cows at the third and the second lactations; and wherehand milking is practiced, application of rigorous hygienic measuresshould be considered
