Abstract
Description
Thirty-three per cent of the calves nursing cows with titers to IBR when vaccinated at one to six weeks of age exhibited no immunological response but an anamnestic response was observed on a second vaccination in approximately 67% of the vaccinated animals. The latter vaccination was made at least one month following the lint vaccination.
