The problems of cattle adaptation in Western Siberia are reviewed. Recently a large number of Holsteins has been imported to the USSR. Therefore the understanding of the physiological and immunological factors controlling the susceptibility of the cow to diseases will lead to more rational approaches to selection and control. The results of several studies indicate that disease incidence and the cost of the breeding program increase with selection for milk yield (Nonnecke and Harp, 1989; Shook, 1989). In this paper, we describe the first results of our 6 year studies on the improvement of milk production and disease resistance of Russian Black and White cattle and Holsteins.
