Summary of neutralization antibody titers of two anti-bovine rotaviruses A (RVA) immunoglobulins Ys (IgYs) and one control IgY against ten bovine RVA isolates.

a IgY titer is expressed as dilution factor of 1 g hyperimmunized IgY powder that showed inhibition of cytopathic effects (CPE) or, in other words, that protected >50% of cells from CPE. Results are presented as the mean of three independent experiments.
