Abstract

The amino acid pool of free amino acids in the blood serum of two European migratory bat species: V. murinus and P. nathusii living in the Urals was studied. Statistically significant differences were noted in the formation of the main metabolic groups of free amino acids in yearlings of migratory species: GGAA, NEAA, EAA, SAA (p < 0.05). In yearlings of the P. nathusii: GGAA predominates – 79.7% and EAA – 49.4%, and in the yearlings of the V. murinus: GGAA predominates – 74.9% and NEAA – 58.4%. Comparative analysis showed no differences between V. murinus and P. nathusii in the percentage of AAA and BCAA (p > 0.05). Statistically significant differences were noted in the formation of metabolic groups of amino acids in the blood of yearlings of migratory species of bats and the resident species of pond bat (p < 0.05).
