A computerized information system for disease surveillance, management and herd health service is presented. The objectives are to describe the incentive method of data collection used to maintain the participation of the farmers and veterinarians in the program, to describe techniques used to select cow records for epidemiologic research and to present incidence rates for the major dairy diseases seen during the study period, 1980–1984. Participating farmers recorded animal events on a daily basis, and their veterinarians recorded the results of all diagnoses and treatments. The data were processed and returned to the farmers and the veterinarians in weekly and monthly reports. The farmers and the veterinarians found that the reports returned to them were useful in managing the health of the herd, and this served as the incentive for continued participation in the program. Lactational incidence rates of the most common clinical dairy diseases were 17.5, 15.1 and 12.8% for metritis, mastitis and cystic follicles, respectively. |
