Abstract. The article presents data characterizing milk production and milk quality indicators of Simmental cows' Austrian selection of different productive types in the process of adaptation for the conditions of foothills of the North Caucasus, the Russian Federation. Simmental cows' milk type by the amount of milk produced is surpassing the cows (meat-dairy and dairy-meat) at the first lactation on 815 and 1934 kg at the second lactation -904 and 2114 kg and at the third -834 and 2030 kg. Analysis of the data revealed relatively high and stable lactation throughout the control period of the cows of all productive types. The content of dry matter, fat and protein in milk was more from the cows of meat-dairy type productivity. The content of nonessential amino acids in milk from the cows of meat-dairy type was more than from dairy cows by 14.5 %, dairy-meat by 9.6 %; the sum of essential amino acids -11.6 and 7.2 %. During lactation, the number of essential amino acids and the total amino acid content decreased in milk from cows all of productive types. The Austrian Simmental cattle breeding different production types characterized as adaptable to the conditions of the North Caucasus foothills.
