Association of Disease Outbreak and Reproduction in Cattle Herds

In order to determine the effects of infectious and parasitic diseases during the reproductive stage of artificially inseminated dairy cattle herds in the municipality of Camagüey, province of Camagüey, Cuba, the monthly data of death causes and number of cases (2010-2014) were collected at the company Triángulo 3. Significant correlations were found between the categories of the reproductive stage and the number of cases, seen as stimulus intensity (none = 0; one case = 1; about 2-4 cases = 2; five or more cases = 3). Probit regression revealed that the higher the stimulus the fewer cows awaiting diagnostic, and the greater the number of empty cows. Hence, these cases had a negative impact on the dairy herd´s reproductive behavior. This study recommends Probit regression as a tool for analysis of health issues associated with variables that define the reproductive status of the herd
