title: [Content of estrogenic hormone in chicken blood serum during laying].
abstract: The fluorescent method is developed for determining the estradiol and estrone contents. The method includes their extraction by organic solvents, aluminium oxide chromatography, fluorescence registration by a special installation. The method is used to determine the content and ratio of estrogenic hormones in the chicken blood serum during laying. A dependence is established between the level and ratio of estrogenic hormones in the chicken blood and the functional activity of the reproductive organs. The dependence shows that in the period of the oviduct growth and development as well as during molting estradiol prevails in the chicken blood, and in the period of intensive laying estrone is predominant, which stimulates the synthesis of the egg ovogenic products.
