Abstract
Progesterone concentration of bovine corpora lutea increased from 29.2 [mu]g/g at day 8 to 47.2 [mu]g/g at day 16 of the estrous cycle. [DELTA]4 Pregnen-20[beta]-ol-3-one (20[beta]-ol) increased from 0.3 [mu]g/g at day 8 to 2.0 [mu]g/g at day 16. Concentration of progesterone ranged from 4.0 to 18.2 [mu]g/g and 20[beta]-ol from 3.3 to 10.5 [mu]g/g in luteal tissue from 7 stages of pregnancy investigated. Blood plasma from pregnant cows contained 0 to 2.1 [mu]g progesterone/100 ml. and no detectable 20[beta]-ol. Placental tissues and fluids did not contain significant quantities of either of these progestins.Keywords
