[Gonadal and adrenal endocrine functions in female minks of 2 genotypes in postnatal ontogeny].

Radioimmune assay has been made of the content of estradiol and progesterone in the blood (from July to March including the 7th day after mating), as well as on the level of estradiol and progesterone production in young females of the standard and mutant sapphire minks in November. It was shown that within certain periods, estradiol and progesterone content of the blood was significantly higher in the standard animals. Gonadal production of estradiol, as well as progesterone production both by the gonads and adrenals in November, were similar in females of both genotypes. It is suggested that sapphire minks have another pattern of correlation between estradiol content of the blood and gonadal production of estradiol as compared to that in standard animals.
