Independent of the synchronisation mode the Serozyme-progesterone levels indicated a cycle length of 17 days. Progesterone was not detectable by the test system during oestrous, it reached its maximum on the 10th day (mean = 3.9/3.7 ng/ml) and decreased to non-detectable levels again on day 17. For early pregnancy diagnosis the Serozyme-progesterone as well as the Ovucheck gave useful results. On day 17 and 19 after mating the progesterone concentration of pregnant ewes remained on the same level as on day 10, whereas barren ewes had non-detectable progesterone levels on day 17 and 19, using the Serozyme-progesterone and below 1 ng/ml on day 19 using the Ovucheck. The accuracy of the Serozyme-progesterone referring to the declaration \"non pregnant\" was 100%, that of the Ovucheck 37.5% on day 17 and 100% on day 19. The use of both test systems for determining pregnancy of unknown length was examined by collecting blood-samples three times with a five and a seven day interval. Precise results were obtained only with the Serozyme-progesterone test. At least one of three blood samples of all the barren ewes (n = 8) contained amounts of progesterone beneath the sensitivity of this method. The Ovucheck results could not help at all to distinguish barren or pregnant ewes with unknown mating data.</p>","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.

A re-activation of treated farm or laboratory animals which is set up too early might produce reduction of efficiency or falsification of experimental results. Investigations on p.op. de-synchronisation have proved that \"healthiness\" means--besides the absence of clinical symptoms--also stable relations among the circadian rhythms. As the ultradian rhythms (wavelength less than 24 h) which exist beside the circadian ones depend on endogenic and exogenic factors much more than the circadian rhythms do, the aim of this study was to investigate strength and especially duration of changes p.op. in using core temperature rhythms of sheep as example, by setting great value on investigating ultradian rhythms. The core temperatures of 5 Merino-mixed sheep were permanently measured for 4 weeks p.op. by special radiotelemetric equipment, under controlled circumstances. All recorded data have been expertised \"macroscopically\" and Fourier-analysis was employed for judging phase shift and intensity of existing rhythms. Though no signs for systemic disturbances could be found and the recorded temperature always was in between the physiological range, important shifts of phases and variations in intensities in the ultradian scope as well as in the circadian one occurred. The \"normal\" or final phase relations and the constant daily pattern of intensities in sheep were reached 16 days p.op. earliest.</p>","PeriodicalId":23904,"journal":{"name":"Zentralblatt fur Veterinarmedizin.
