The article presents data on growth, clinical and blood morphological indicators of Simmental bulls of different production types, as well as heat resistance index. The live weight of intensively bred bulls was 480-520 kg at 18 months, and the live weight of meat-milk type bulls was 29.5 kg (5.8%) more than their peers of milk-meat type. Also, bulls of this type had higher growth rates in all breeding periods. Clinical, hematological and heat resistance indicators of Simmental breed bulls are at the standard level, which indicates that they are well adapted to local climate conditions. Key words: Simmental breed, production types, live weight, growth, development, respiratory movements, pulse, body movement, erythrocytes, leukocytes, hemoglobin, heat resistance index.
