Regarding traditional vaccines, several reports have shown that cattle vaccinated with non-deleted modified-live vaccines transfer neutralising antibodies (NA) to the newborn calves that can protect them from experimental infection [12, 13] , and other studies have demonstrated that a poor titre of colostral antibodies increases the risk of contracting BoHV-1 infection in the calf [14] . In addition, the antibody titres observed in both the groups of newborn calves, born to the cattle immunised with vaccine A or B (0.85 log 10 and 0.75 log 10 , respectively), on PCD180 were lower than those required to protect them against infection by BoHV-1. ./cache/cord-290705-7xkt6u73.txt ./txt/cord-290705-7xkt6u73.txt
