Abstract
The purified colostral immunoglobulins from just after parturition to 72 hours (at 12 hours interval) were processed for the titration of antibodies against foot and mouth disease virus types Asia-I, A and O. Geomean titres against Asia-I were 119.2,51.98, 25.99,7.99, 4.92, 1.62 and 1.23,respectively. For type A, geomean titres were 39.39, 27.85, 10.55, 7.99, 7.99, 1.41 and 1.23,respectively. For type 0, geomean titres were 27.85, 6.49, 6.46, 3.99, 1.74, 1.23 and 1.23, respectively. Antibody titres against Asia-I were higher than those for A and O. Biological half- lives of colostral antibodies to virus types Asia-I, A and 0 were 10, 14 and 17 hours respectively.
