Abstract
When the percentage of leukosis-positive cows in a dairy herd in which leukosis is being eradicated does not exceed 1%, it is feasible to produce leukosis-negative calves to be passed on to raising units. When calves from leukosis-free and leukosis-infected herds are sent to the same unit, they can be reared in the same environment until the age of 8-9 months subject to very strictly applied hygienic measures, such as clear and permanent identification of those from leukosis herds, total separation with continuous partitions on slatted floors, regular blood testing and rapid transfer of any positives out of the negative group, thermal de-horning, disinfection of wounds from hoof-trimming and ear-tagging, and strict needle hygiene.
