Abstract
The effect of maternal separation on in vivo and in vitro immune parameters was studied in young hybrid deer. Groups of fawns separated from their mothers either 2 days prior to or 7 days post immunization with keyhole limpet hemocyanin were compared with a control group of immunized, unseparated fawns. Animals separated prior to antigenic challenge had significantly higher concentrations of antigen-specific IgG in their serum than control animals. There was no influence on the humoral immune response in animals separated following immunization. In contrast, Con A transformations were transiently depressed in separated animals compared to the control group. The time separation was imposed relative to challenge and therefore influenced the subsequent immune response.
