Breeding stock of Aberdeen-Angus breed of import selection at SCC "Lyaskovichi" of Petrykov area showed a high adaptive capacity of animals to changing environmental conditions during freezing conditions of winter in Belarus. Indicators of acclimatization and adaptation abilities of cows and heifers of Hungarian and national selection meet the physiological norms. In a comparative analysis the number of red blood cells (RBC) was at the level of 6,65-6,80. 106/mm3 in excess by 0,15. 106/mm3, or by 2.3%, in animals of Hungarian selection. The hematocrit (HCT) is marked within 30,70-32,72%, which is 2.02% higher than that of domestic animal breeding. At the level of hemoglobin (HGB) of 11,0 and 11,82 g / dl its mean concentration (MCHC) was 37,62 and 38,76 pg, respectively, in animals of import and domestic selection. Total protein levels in blood of cows and heifers was 1.36 g / l, or by 1.7% Higher than in animals of domestic selection, heifers – 79,04-79,4 g/l, with a slight difference between groups of 0.36 g/l
