Introduction. Bovine leucemia virus (BLV) is an exogenous retrovirus and one of the most common infectious viruses of cattle with a worldwide distribution. The bovine leukaemia virus (BLV), which is structurally and functionally related to the human T-lymphotropic virus types (HTLV)-I and II, is the etiological agent of enzootic bovine leucosis (Tamašauskas, 1973; Ming-Che et al., 1989; Oszvary, 2004; Ikeda et al., 2005; Milius ir kt. 2005). The prevalence of BLV infection in the Lithuanian dairy cattle is low. Nevertheless, BLV infection in cattle should not be ignored by the breeders and their organizations, or by the national authorities responsible for animal health and welfare (Milius, 2006). There are no studies in Lithuania of bovine viral diseases, added to the list of TEB controlled diseases, the prevalences of various factors impact prevention of efficiency research. Objective of this work - is to evaluate the impact of genetic factors to the prevalence of bovine leucosis in populations of Lithuanian Dairy cattle. [...].
