The aim of our research was a comparative analysis of the technology and the efficiency of egg incuba-tion cross "Lohmann White, Lohmann brown, Lohmann sandy", JSC “Poultry farm „Sverdlovskaya“”. The author considers the stages of technology of egg incubation, biological control before incubation, during and after incubation indicators of the three studied crosses were obtained and analyzed. For the incubation of eggs “Poultry farm „Sverdlovsk“” use incubator IPU-f-45. Eggs laid in large batches, simultaneously loading all of the Cabinet (104 pan). According to the results of biological control lessons learned: the first biological control of cross Lomann White superior cross Lohmann brown and Lohmann sandy; after the second biolog-ical control of cross Lomann White a large number of frozen embryos – 7042; Lohmann brown and Lohmann sandy in the results of biological monitoring after incubation showed almost the same perfor-mance. When analyzing the reasons for losses during incubation revealed that a large number of embryos died at the cross Lomann White – 14,03 unfertilized, blood – ring 1,8, motionless 16,3, weak 2,8, cripples 4,3, not hatched chick 7,2 compared to other crosses. Cross Lohmann brown and Lohmann sandy have al-most equal performance. On the basis of obtained results the author convincingly concludes that, in compari-son with the planned indicators of the output of young by “Poultry farm „Sverdlovsk“” to 81.9 %, the differ-ence is the cross Lomann White – 1,65 %, on the cross Lohmann brown – 2,23 % and Lomann sandy – 2,76 % to the downside.
