[Antibodies against dietary proteins and intestinal permeability to macromolecules in the preruminant calf receiving pea flour].

Feeding a milk-substitute diet containing raw pea flour to preruminant calves resulted in the production of anti-pea protein antibodies. Immunoreactive legumin could be evidenced in blood plasma between the second and the fifth meal. Plasma immunoreactive beta-lactoglobulin increased up to the third or seventh week and decreased thereafter, showing a transient rise of gut permeability to macromolecules, probably due to intestinal inflammatory reactions.
