Three experiments were carried out to determine the effects of OB and GnRH on beef suckler cows at various stages post partum. In experiment 1, the first post partum oestrus occurred at 36 ! 17 (mean ± SD), 44 ! 25 and 43 ! 22 days post partum for animals injected with 400 fL9 OB or 100 fL9 GnRH at days 15 and 30 post partum and controls, respectively. The first post partum ovulation, based on elevated plasma progesterone levels, occurred at 37 ! 17 (mean ± SD), 31 ! 18 and 34 ! 10 days post partum for these three groups, respectively. Neither OB nor GnRH increased the numbers of animals which exhibited LH peaks at day 15 or 30 post partum or which showed a subsequent rise in plasma progesterone. There was a high proportion of silent ovulations early in the post partum period. In experiment 2, the time from parturition to the first subsequent oestrus was 93 j- 18 days for animals given 20 fL9 of an LHRH analogue (Hoe 766) between days 37 and 77 post partum, and 86 ! 28 days for controls. Significantly more (P < 0.01) treated cows than controls had elevated plasma progesterone levels following the time of treatment. In experiment 3, animals given two injections of 100 mcg progesterone and one injection 20 fL9 Hoe 766 at two day intervals between days 26 and 87 post partum had an interval between calving and first subsequent cestrus of 81 ! 22 days (mean -L SD) and this interval for controls was 83 ! 13 days. Five of seven treated animals exhibited cestrus 21-22 days after treatment suggesting occurrence of a silent ovulation after treatment.","PeriodicalId":7885,"journal":{"name":"Annales De Biologie Animale Biochimie Biophysique","volume":"140 1","pages":"1575-1587"},"PeriodicalIF":0.0,"publicationDate":"1979-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82710841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(1) In 57-day male fetuses, UAPT level was 3 to 4 ng/mi ; it dropped to 0.5 to 1 ng/ml near 75 days and stayed at that level until term. This content in female fetuses remained at about 1 ng/mi throughout gestation (fig. 1). (2) During the second-half of gestation, UVPT content was generally lower than UAPT content, whatever the fetal sex (table 1). (3) AFT level was clearly lower than UAPT or UVPT level ; it stayed under the sensitivity limit of the assay method in most of the female fetuses. The AFT concentration curve in male fetuses was parallel to that of UAPT (fig. 2). The correlation coefficient (r = 0.71) (fig. 3), together with the relatively large quantities of AFT in 37 to 50-day male fetuses, suggested that the fetal testis could secrete testosterone at a very early stage when the Leydig cells were not yet recognizable.

A fluorescence microscopy technique using diacetylfluorescin (FDA) as a substrate has been tested for the evaluation of the viability of early bovine embryos. Five to 8-day old cattle embryos were incubated in PBS containing FDA concentrations of 1 : 400 000 or 1 : 800 000 for 3 to 5 min at room temperature. Embryos were then examined by reflected light fluorescence using a KP 490 and 520 barrier filter in a Zeiss Axiomat microscope. Their mitotic activity after 24 hrs culture in vitro was used to determine their viability. After 3 min of incubation in the FDA medium, 85 p. 100 of the brilliantly fluorescing embryos showed mitoses after culture. None of the non-fluorescing embryos developed in vitro. Some embryos (about 6 p. 100) contained both dead and living cells as determined using the FDA test ; a few of these differentially reactive embryos were viable, but most of them were not. Short-term incubation of embryos in FDA medium probably did not impair their development, and no teratogenic effects could be seen in 17 to 20-day old rabbit fetuses transferred after the FDA test.","PeriodicalId":7885,"journal":{"name":"Annales De Biologie Animale Biochimie Biophysique","volume":"25 1","pages":"1625-1629"},"PeriodicalIF":0.0,"publicationDate":"1979-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75882948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
