              Abstract 
 
              Aim: A study on surveillance 
              of bovine brucellosis in dairy herds of peri-urban areas under 
              intensive system of production was carried out by milk-ELISA. 
              Various risk factors were identified having significant 
              association with occurrence of bovine brucellosis in dairy herds 
              of peri-urban areas.Materials and Methods: Five randomly selected peri-uban 
              areas of six cities of Gujarat were included in the present study. 
              Five randomly selected dairy herds under intensive system of 
              production from each selected peri-urban area were included for 
              further investigation. In total, 199 bulk and 582 individual milk 
              samples were screened by milk-ELISA. Forty three different risk 
              factors were identified and grouped into four major categories as 
              general characteristics of farms, introduction of infection to 
              farms, management systems of farms and exposure of disease. 
              Further, their distribution and association with prevalence of 
              bovine brucellosis was studied.
 Results: The overall herd and animal prevalence in peri-urban 
              areas was 33.70 and 11.90%, respectively. Out of 11 risk factors 
              on general characteristics of dairy farms, only five (herd size, 
              type of animals, type of breed, age of owner and knowledge gained 
              by owners) showed significant (p<0.05) association with occurrence 
              of bovine brucellosis. None of risk factors on introduction of 
              infection to farms (n=6) and management systems of farms (n=11) 
              was found significantly associated with occurrence of brucellosis. 
              Among risk factors on exposure of disease (n=15), history of 
              abortion, retention of placenta, still birth and metritis/endometritis 
              showed significant (p<0.05) association with prevalence of bovine 
              brucellosis.
 Conclusion: It was concluded that prevalence of bovine 
              brucellosis in dairy herds under intensive system of production in 
              peri-urban areas of Gujarat was comparatively higher than reported 
              overall prevalence of brucellosis. Risk factors like larger herd 
              in close confinement without adequate sheds, type of animal, type 
              of breed and knowledge/awareness of dairyman, unrestricted animal 
              market, replacement without prior testing, reproductive disorders 
              with absence of their testing are the important risk factors under 
              the intensive production system of peri-urban areas of Gujarat, 
              India.
 Keywords: bovine brucellosis, milk-ELISA, peri-urban area, 
              risk factors.
