Abstract
A method for screening of immunoglobulin levels in porcine fetuses is presented. The method is based on rocket electrophoresis. This method is sensitive, but when used for assaying immunoglobulins it is only semiquantitative. It was shown that sera from 11 hysterectomy-derived colostrum-deprived neonatal pigs from a normal gilt contained no IgM or IgA, but small amounts of IgG. Sera from 9 piglets isolated in the same way from a gilt infected with porcine parvovirus contained all 3 antibody classes. IgM was detected by an interspecies reaction using anti human μ-chain immunoglobulin.
