The aim of this paper is to add to the genealogical structure of breeding Black and White cattle, to analyse their productivity and other profitable features of farms by methods of genetic statistics. The Results of Survey. The first line of Black and White bulls in Lithuania were Plessas LT 149, Gulbių Riteris LT 277, Olaf LT 276, Hanmaksas LT 1200, Kraft-Stipruolis LT 1201, Garsas LT 200 and etc. In Lithuania a new period of creation and breeding of Black and White genealogical structure started when Black and White cattle from Holland were used en masse in order to improve the cattle breed. The best Black and White bulls from Holland were chosen as initials. Those breeds were: Annas Adema 30587, Wytsturt Annas Adema 36079, Frizo Wouter 33116, Haubois Annas Adema 44162, Diamant 33251, Haskera Governeur 44506, Hiltjes Adema 37910, Rotterda Paul 36498, Jelsumer Rudolf Jan 42884 and Adema 25473. The evaluation of bull’s inheritable features was done with help of features of descendant’s productivity and cattle’s were chosen and bought very purposefully. From 1967 till 1976 the following breeds were created: B. Pieter LJ 305, Sietse LJ 340, Hildoj 363, Katso LJ 483, Vautero LJ 738 and some lines of Klaso LJ 335, Adema LJ 770. Paulio LJ 771, Imperatoriaus LJ 1160, Burto LJ 2085, LangerioLJ 2523 descent.
