Abstract
Several molecules, including glucocorticoids (cortisol, corticosterone,
etc.) and testosterone in mammals, are thought to be associated
with tame/aggressive behaviour towards humans, but these relationships
remain controversial. The American mink (Neogale
vison) represents a model in the studies of physiological
traits in aggressive and tame behavioral phenotypes. Given the seasonality
in reproduction, fur moulting, and hormonal levels during the life
cycle of mink and the reciprocal relationships between the hypothalamic–pituitary–adrenal
and hypothalamic–pituitary–gonadal axis, it is necessary to study
the levels of cortisol and testosterone in the behavioral phenotypes
of the animals in various seasons. Of particular interest is the
period after the breeding season (late March—early April), when
the level of androgens decreases. The aim of the study was to characterize
the neuroendocrine physiological phenotypes associated with aggressive
and tame behaviors by measuring the levels of cortisol (basal level)
and testosterone in the blood serum of American mink at the end
of the breeding season. Blood samples were taken from animals selectively
bred for tame and aggressive defensive reaction towards humans at
the Institute of Cytology and Genetics in Novosibirsk, Russia. No differences
were found in serum levels of cortisol and testosterone between
aggressive and tame mink. We found a significant negative relationship
between the studied hormones in tame mink. Thus, selection of American
mink for either aggressive or emotionally positive responses to
humans does not appear to be associated with changes in the levels
of the hormones studied at the end of the breeding season.
