Abstract

A study was undertaken in a California dairy to estimate the risk of transmission of bovine leukemia virus associated with rectal palpation of cows. The probability of seroconversion within 3 months after rectal palpation was examined as a function of the prevalence of infection in cows at the time of palpation. It was hypothesized that the probability of seroconversion within 3 months after palpation would be higher for cows in a group with high prevalence of infection than for cows in a group with low prevalence. The probability of seroconversion after rectal palpation was equal to 0.034, and results of logistic regression, using data from 1,116 noninfected and 1,047 infected cows, did not indicate any significant association between probability of seroconversion after rectal palpation and prevalence of infection (P = 0.189). Results of this study suggest that risk of bovine leukemia virus transmission by rectal palpation typically used in reproductive tract examination of cows either does not occur or is uncommon.
