An experimental line of White Leghorns (WSU-VS) and a commerical line inoculated with turkey herpesvirus (HVT) at 1 or 8 weeks old did not differ in the occurrence of infectious cell-free HVT in their feather-tip preparations (FT-HVT). The birds examined at 2 weeks postinoculation (PI) were always positive for FT-HVT regardless of age at virus inoculation, dose of HVT inoculated, or genetic line of chickens, whereas only a few were positive at 4 weeks and none at 6 weeks PI.
一个白来航鸡实验品系（华盛顿州立大学 - 兽医学院品系，WSU - VS）和一个在1周龄或8周龄时接种火鸡疱疹病毒（HVT）的商业品系，其羽尖制剂（FT - HVT）中无细胞感染性HVT的出现情况并无差异。无论病毒接种时的年龄、接种的HVT剂量或鸡的遗传品系如何，在接种后2周（PI）检查的鸡的FT - HVT总是呈阳性，而在接种后4周只有少数呈阳性，在接种后6周则无阳性。
