Cibungbulang District of West Java is a region where has a population of dairy cattle and it has been pointed as one of central livestock comunity (Sentra Peternakan Rakyat, SPR). However, parasitic diseases remains a major problem at the area. The purpose of study was to determine parasitic diseases attacking Friesian Holstein (FH) dairy cattle in the Cibungbulang District of West Java. Examination of stool and blood serum should be done to strengthen the diagnosis of parasitic diseases. A total of 130 blood and faeces was collected. Stool examination was conducted using Withlock method to calculate and observe the egg shape of worms including Eimeria sp. Blood sera examination were carried out for serological tests of Trypanosoma evansi based on Card Aglutination Trypanosomiasis Test (CATT) -T. evansi method. The results showed 36.92% (48/130) FH cattle were infested by Trichostrongylus spp, 2.31% (3/130) by Toxocara vitulorum, 20% (26/130) by Eimeria sp and others were negative, 40.77% (53/130). In addition, 14.62% (19/130) sera possessed a positive response for CATT test, consisting 6.15% (8/130) of medium agglutination (+),6.92% (9/130) of strong agglutination (++) and 1.54% (2/130) of weak agglutination/dubious (±). In conclusion, FH cattle in Cibungbulang District are infested by internal parasites (worms and Eimeria sp) and are positive serologically for T. evansi. In term of management system, farmers should maintain level of environmental sanitation to increase milk production.
