The aim of this study was to collect further data about levels of endogenous hormones in foodstuffs derived from animal production. Because of expected higher concentrations of especially estrogens in colostrum compared to other foodstuffs, our investigation focused on this matrix. For evaluation of endogenous steroid hormones in separated colostrum (fat and defatted fraction) and colostrum powder, the relevant free and conjugated estrogens (estradiol-17β, estradiol-17α, estrone, and estriol… CONTINUE READING
