title: [Progesterone determination in milk].
abstract: Samples of milk were taken every sixty minutes in ten cows for a period of ten hours to determine the concentrations of progesterone. The concentrations recorded were related to those in the strippings. All these samples furnished adequately reliable evidence of the presence of an active corpus luteum, with the possible exception of those taken during the last hours prior to milking in some cases.
