Key result
Serological evaluation of a dairy herd revealed that 98.7% of dams and 5.1% of their precolostral calves were seropositive for Bovine Enterovirus Type 1.
Why the study?
Precolostral antibody evaluation detects in-utero infections, but serological evaluation of Bovine Enterovirus Type 1 in dams and their newborn calves needed investigation.
Population
155 dams and their 155 precolostral calves on a large-scale dairy farm

Precolostral BEV1 antibodies flag in-utero infection; leaves open whether this alters calf outcomes or herd management.
Cross-Sectional (n=310)
No
Absolute Event Rate: 98.7% vs 5.1%
Precolostral antibody control in newborn calves is a feasible tool for detecting recent in-utero BEV1 infections in dairy herds.
Birdane et al. (2019) conducted a cross-sectional in Bovine Enterovirus Type 1 (BEV1) infection (n=310). Bovine Enterovirus Type 1 (BEV1) infection was evaluated on BEV1 seropositivity. Serological evaluation of a dairy herd revealed that 98.7% of dams and 5.1% of their precolostral calves were seropositive for Bovine Enterovirus Type 1.
