[Importance of saliva and colostrum in leukemia transmission in cattle].
Studied was the occasional role played by the saliva of leukotic cows in the transmission of the infection to test lambs along with the role of colostrum as a factor neutralizing the leukosis virus in experimentally infected lambs. It was found that bovine leukosis could be transmitted by the saliva of affected animals. Colostrum that contained hightiter specific antibodies was found to be effective in neutralizing the leukosis virus in newborn calves provided no subsidiary infection took place.
