Antibody titres against rota virus in purified colostral immunoglobulins at zero hour Gust after parturition) as determined by Streptavidin Biotin Peroxidase Enzyme Linked Immunosorbant Assay (ELISA) ranged from 1:6 to 1:2048 with geometric mean titre 311.88~ While at 72 hours it ranged from 1:8 to 1:64 with geometric mean titre 10.76. Antibody titres against corona virus at zero hour ranged from 1:16 to 1:64 with geometric mean titre 31.98. While at 72 hours it ranged from 1:2 to 1:16 with geometric mean titre 5.38. The results indicated the presence of rota and corona viruses infections in crossbred cows and support the evidence for an etiological role of these viruses in newborn infections.
