Abstract :The clinical and haematological findings in dairy cattle with naturally infected bovine immunodeficiency virus insert ignore into journalissuearticles values(BIV); infection were evaluated. Thirty-seven insert ignore into journalissuearticles values(12.3%); out of 300 cattle that had previously been found positive for BIV infection were monitored. Thirty-seven BIV-free cattle selected from BIV-positive herds were used as a control group. Routine clinical and haematological parameters were recorded 6 times, at 1-month intervals. Mastitis insert ignore into journalissuearticles values(n = 18);, metritis insert ignore into journalissuearticles values(n = 9);, respiratory system diseases insert ignore into journalissuearticles values(n = 8);, retained placenta insert ignore into journalissuearticles values(n = 7);, and regional lymphadenopathy insert ignore into journalissuearticles values(n = 7); were predominantly diagnosed during the monitoring period in BIV-infected cattle, and mastitis insert ignore into journalissuearticles values(n = 1); and metabolic disturbance insert ignore into journalissuearticles values(n = 1); in the control animals. Heart and respiratory rates were significantly higher insert ignore into journalissuearticles values(P < 0.01); in BIV-infected cattle than in the control group. White blood cell insert ignore into journalissuearticles values(WBC); count and lymphocyte rate were lower insert ignore into journalissuearticles values(P < 0.01); in BIV-infected cattle, but the neutrophil rate was higher insert ignore into journalissuearticles values(P < 0.05); than those of the control group. There were no significant differences in erythrocyte or platelet indices within or between the groups during the study. These findings suggest that the presence of BIV infection should be considered a health risk to cattle populations, and may have a role in changing WBC and differential cell counts in the host.
