The article presents data on the study of exterior characteristics and milk productivity indicators of Simmental cows of different production types, imported to the Republic of Uzbekistan from European countries. The data obtained on the milk productivity of experimental Simmental cows shows that this imported cattle is well adapted to hot climate conditions. Dairy type cows are distinguished by their tall stature with an elongated body, deep chest, strong constitution, desirable shape and optimal udder measurements, which determined high milk productivity and better suitability for machine milking compared to dairy-meat and meat-dairy types. The average daily milk yield of full-aged Simmental cows of the dairy type for the first 100 days of lactation was 16.83 kg with a milk fat content of 3.82%, which is 8.6 and 15.6% more than cows of the dairy-meat and meat-dairy types. Dairy cows also used fewer energy feed units per unit of production compared to other types. To form dairy herds of Simmental cattle, it is recommended to select according to the physique, shape and measurements of the udder and milk productivity of first-calf heifers.
