It is determined that hybrid young pigs derived from crossing of boars of Duroc and Land-race breeds of Canadian selection with cross breed sows of Great White x Belarusian Meat breeds and Belarusian Meat x Landrace breed of native selection differs by higher erythrocytes content, hemoglobin and total protein content in blood that indicates a higher intensity of metabolic processes that is peculiar of animals of meat productivity. So hybrids (Great White x Belarusian Meat) x Landrace, (Belarusian Meat x Landrace) x Duroc and (Belarusian Meat x Landrace) x Landrace at 4 months of age had the content of total protein in blood serum was on 0,93-2,71 g higher (P less than 0,001) in comparison with analogues of control group. By 6 months of age the difference on the given trait comparing to control group of the given crosses made 1,31-2,78 g (P less than 0,001) correspondingly
