On faculty of genetics and cultivation of agricultural animals of 'Grodno State Agrarian University', in laboratory of industrial biotechnology 'Polesye State University' researches are carried out in 2010 – 2011. Object of research were sons and grandsons of bulls-manufacturers - carriers of immunodeficiency syndrome, and also their contempoparies containing in APK 'Progress-Verteloshki' on a complex on large horned livestock feeding 'Borki'. During carrying out researches it is established that distinctions on a daily average gain of live weight between sons and their contemporaries, grandsons and their contemporaries, a manufacturing bull the Thrush of 400092 P0,05 - P0,01, during the entire periods of post-natal development contemporaries in both experiences were characterized by higher level relative increase in live weight the live weight which dynamics testifies to ability of animal data of groups longer time to keep high growth rate; studying of morphological composition of semi-carcasses of experimental animals showed that considerable distinctions on an exit of pulp were observed in shoulder blade, cervical and coxofemoral parts of semi-hulks (P0,01 - P0,001) bulls not being carriers of a syndrome of a hereditary immunodeficiency.
