A method for assessment of nervous system type in replacement bulls and breeding bulls in which a nervous system type index is determined for assessment of stress-resistance level in replacement bulls and breeding bulls, that includes dynamic determination of blood indices, namely concentration of enzymes: cortisol and testosterone; activity of enzymes: creatine phosphatekinase, alanine aminotransferase and aspartate aminotransferase. Individual features of animals are identified by dynamics of the indices after stress loading in comparison to initial value thereof before this and to the reference rate by integrated parameter - nervous system type index. |
