Evaluation of sire bulls for the quality of offspring in organic and conventional milk production was carried out. In 2022, the most promising lines and sire bulls in organic and conventional milk production were identified, which can be used in repeated selection plans, provided that inbreeding is prevented. The daughters of bulls represented by PE “Galex-Agro” were characterized by higher milk production, better reproductive capacity and live weight dynamics during their rearing period compared to their peers in the conditions of “Miroslavel-Agro”. It was not possible to study the effect of housing technology on the manifestation of the genetic potential of bulls' daughters, since different bulls were used in organic and conventional milk production. However, there is a tendency that in the conditions of both farms, the descendants of the Redada line were the best (Rumgo AT 168213272 - PE “Halex-Agro”, Radi CZ 20997683 - SLC “Miroslavel-Agro”). The data obtained convincingly indicate the expediency of using these bulls in the conditions of both farms.
