[Comparative estimation of phylogenesis of Vietnam dairy cattle using the Serebrovskiĭ, Hedrick and Rogers methods]

Starch gel electrophoresis has been used to study polymorphism of proteins of blood (Hb, Tf, Al) and milk (alpha S1-Cn, beta-Cn, beta-Lg) in animals of the Holstein-Friesian (n = 140), Leisindian (n = 32) breeds and their hybrids (F1, n = 34); F2, n = 37; F3, n = 31) reared in Vietnam. It has permitted comparatively studying phylogenesis of anew formed dairy cattle using the Serebrovskiĭ+, Hedrick and Rogers methods. This comparative study has yielded similar results.
