	abstract = {Bovine milk has been reported to contain low levels of Immunoglobulin A (IgA) in comparison to human milk (0.1 g/L vs 1.0 g/L, respectively) (Butler, 1999). However, analysis of milk collected from cows vaccinated to induce antigen-specific IgA secretion in milk (Hodgkinson, et al., 2007) has demonstrated that the IgA response of individual cows is variable, with a ~10-fold range in the IgA production by individual vaccinated cows at peak lactation (E.A. Carpenter, Unpublished data). Approximately 10\% of these cows are classified as {\textquotedblleft}high milk IgA producers{\textquotedblright}, defined by Wagter et al.(2000) as those cows with a milk IgA concentration greater than one standard deviation above the group mean.},
