India, a major livestock region of the Asian countries is rich in animal genetic resources. There are about 30 recognized native breeds of cattle in India having special qualities of hardy nature, resistance to many diseases and adopted to adverse climatic condition. Production of high yielding crossbred dairy cows without compromising on disease resistance is a concept that is very enticing to dairy researchers and conservationist in India. Bovine Lymphocyte Antigen DRB3 (BoLA-DRB3), a gene of the major histocompatibility complex (MHC) has received attention because this is considered to be a potential genetic marker associated with disease resistance traits in cattle. At present, more than 100 different alleles were investigated by PCR-RFLP (Van Eijk et al., 1992; Gelhaus et al., 1995; Maillard et al., 1999; do Nascimento et al., 2006). Hence, a study was taken up to characterize BoLADRB3.2 alleles in the native animals of Deoni and Ongole breeds of cattle.
