Abstract
The variation in serum levels of immunoglobulins IgG, IgA and IgM has been studied during the early development of the young pig using radial immunodiffusion assays with specific rabbit antisera. Antibodies against Escherichia coli 08 and 0141 were assayed by antiglobulin haemagglutination and bactericidal techniques.
