[Effect of color mutation on the function of the adrenal cortex in chronic feed stress in American mink].
Effect of color mutations, headlund and aleutian, on the adrenocortical function was studied in American mink under stress conditions. The adrenocortical function was analysed in the course of gland's incubation in vitro. Natural environmental factors (sharp fall of temperature) and artificially limited feed served as stress factors. It was shown that minks heterozygous for color mutant alleles studied were more resistant to the stressors. This is associated with genetically mediated peculiarities of the action of hypophysial adrenocortical system which is characterized by more adequate reactivity towards stimuli acting. Thus, the effect of heterosis in minks heterozygous for color alleles may well be caused by their increased resistance to stress.
