title: [Radioimmunologic determination of progesterone and rectal ovarian palpation in embryonic death in cows].
abstract: Repeated radio-immunological assays of progesterone in milk and ovary rectal palpation were used for indirect determination of embryonal mortality in cows. Milk sampling and rectal examination were made in the insemination period and then in two- to three-day intervals, mostly from the 21st day after insemination till the early pregnancy determination made after the 42nd day on the basis of the double wall phenomenon. Observation was made in 185 animals from two herds. Embryonal mortality was found in 9.06% out of 289 evaluated inseminations, which prolongs the oestral cycle over 25 days. The monitoring corpus luteum function in connection with rectal ovary palpation supplemented by oestrus, ovulation and insemination control enable a more objective indirect diagnosis of embryonal losses prolonging the oestral cycle.
