Incidence of hereditary Citrullinemia and bovine leucocyte adhesion deficiency syndrome in Indian dairy cattle (BOS TAURUS, BOSINDICUS) and buffalo (BUBALUS BUBALIS) population

PCR based screening of the cattle and buffaloe bulls for Bovine Leucocyte A dhesion Deficiency Syndrome (BLAD) and Citrullinemia genetic disorders were carried out. A total of 330 cattle belonging to 4 breeds and 135 buffaloes of 3 breeds were genotyped. One young Holstein bull was detected as carrie r (0.67%) for mutation at codon 86 in the argininosuccinate synthetase gene locus. Two young Holstein bulls were diagnosed as heterozygous (1.33%) for the BLAD locus. So far no carriers were detected in the indigenous cattle and buffalo breeds.
