The effects of sexual steroids (17.beta.-estradiol alone and of its combination with progesterone and/or testosterone) on blood levels of total lipid, carotene and lipid-soluble vitamins A and E were investigated in non-laying hens. During a treatment of 4 wk, the plasma levels of these compounds were measured weekly. The total lipid content increased systematically in the groups treated with estradiol and estradiol + progesterone. The carotene level showed non-significant variations. The vitamin E content of plasma increased significantly in the estradiol-treated group at the end of the 1st wk of treatment. The retinyl ester level showed a peak in the 2nd wk in the estradiol-treated group. The changes in the retinol level were similar to those in vitamin E.
