Table 2 Total number and proportion of calves (%) that became viremic and shed virus in nasal secretions after challenge (days 0 to 28) with BVDV 2 1373 in each group

From: Efficacy of multivalent, modified- live virus (MLV) vaccines administered to early weaned beef calves subsequently challenged with virulent Bovine viral diarrhea virus type 2

Group Number of viremic¥ calves (%) Number of viremic calves that shed virus (%)
A 11 (90)* 8 (72.7)*
B 2 (16.6) 0
C 3 (25) 0
D 6 (54.5)* 2 (33.3)
  1. ¥, viremic calves = calves with a BVDV positive sample in WBC or serum.
  2. A higher proportion of control (A) and group D calves became viremic and shed virus after challenge compared with calves from groups B and C. The star *sign refers to statistical significance (P < 0.05).
