Abstract
Immunoglobulin concentrations (IgG, IgM and IgA) in bovine serum, follicular fluid and uterine and vaginal secretions were determined. The specificities of IgG, IgM and IgA for virus-neutralizing antibody against bovine viral diarrhea (BVD) and infectious bovine rhinotracheitis (IBR) viruses were also examined. High concentrations of IgG were present in serum and follicular fluid. The IgG, IgM and IgA concentrations were low in uterine and vaginal secretions. There was more IgG in the uterus during estrus than at any other time. Virus-neutralizing antibodies against BVD and IBR in serum of cows were mainly the IgG class. There was positive correlation between serum and follicular fluid virus-neutralizing antibody titers for BVD and IBR. These antibodies may provide some protection for recently ovulated ova.
