QUANTITATION OF IMMUNOGLOBULINS (IGG, IGM AND IGA) IN SERUM AND LACTEAL SECRETION OF BUFFALOS (BUBALUS-BUBALIS)

Buffalo immunoglobulins (Igs) IgG(1), IgG(2) IgM and IgA were prepared and monospecific antiserum was raised against each. These were utiliz ed to quantitate Igs in 66 sera samples and lacteal secretions of 3 bu ffaloes from 0 to 84 hr postpartum. The concentration of Igs in serum was unaffected by age of the animals and their distribution was normal . The mean IgG(1), IgG(2), IgG, IgM and IgA concentration in serum was 17.46, 14.08, 31.54, 2.92 and 0.27 mg/ml, respectively. The correspon ding values in lacteal secretions of the 3 buffaloes immediately postp artum were 31.62, 1.96, 33.58, 0.52 and 0.27 mg/ml, respectively. Ther eafter the Ig concentrations declined sharply, 7-fold by 24 hr and mor e than 30-fold by 84 hr postpartum.
