Natural Resistance and Biochemical Content of Blood of Pure Breed and Hybrid Young Animals

Abstract

It is determined that hybrid young pigs derived from crossing of boars of Duroc and Landrace 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 0,93-2,71 g% higher (P ≤ 0,001) compared to 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≤ 0,001) correspondingly.
