Subject:
corpus luteum; jugular vein; luteinizing hormone; pregnancy; progesterone; secretion; sows; vena cava
Abstract:
... The aim of the present study was to explore the relationship between systemic and local progesterone secretion and LH pulsatility during implantation in the pig. Differences in progesterone concentrations measured locally in the caudal vena cava and systemically in the jugular vein were studied in eight primiparous sows on Day 14 of pregnancy. LH pulsatility was analysed for its effects on the loc ...

beef cows; blood flow; blood sampling; corpus luteum; correlation; ovulation; progesterone; regression analysis; ultrasonography
Abstract:
... Colour Doppler ultrasonography was used to compare the ability of preovulatory follicle (POF) blood flow and its dimensions to predict the size, blood flow and progesterone production capability of the subsequent corpus luteum (CL). Cows (n=30) were submitted to a synchronisation protocol. Follicles ≥7mm were measured and follicular wall blood flow evaluated every 12h for approximately 3.5 days un ...

3. Inducing ovulation with oestradiol cypionate allows flexibility in the timing of insemination and removes the need for gonadotrophin-releasing hormone in timed AI protocols for dairy cows

Holstein; dairy cows; estradiol; estrus; gonadotropin-releasing hormone; insemination; ovulation; pregnancy rate; progesterone; prostaglandins
Abstract:
... The effects of addition of gonadotrophin-releasing hormone (GnRH) to a progesterone plus oestradiol-based protocol and timing of insemination in Holstein cows treated for timed AI (TAI) were evaluated. Cows (n=481) received a progesterone device and 2mg oestradiol benzoate. After 8 days, the device was removed and 25mg dinoprost was administered. Cows were allocated to one of three (Study 1; n=57) ...

blood; body weight; embryogenesis; fathers; females; fetal development; granulocyte-macrophage colony-stimulating factor; males; mice; mothers; paternal effect; postnatal development; pregnancy; progeny; progesterone; testosterone
Abstract:
... The modification of pre- and postnatal development conferred by immunogenic stimulation of mothers provides a population-level adaptation mechanism for non-genetic transfer of maternal experiences to progeny. However little is known about the transmission of paternal immune experiences to offspring. Here, we show that immune priming of males 3–9 days before mating affects the growth and humoral en ...

Subject:
beef cows; corpus luteum; correlation; diestrus; endometrium; gene expression; genes; ovulation; phospholipase A2; progesterone; prostaglandins
Abstract:
... We hypothesised that different endocrine profiles associated with pre-ovulatory follicle (POF) size would impact on uterine prostanoid pathways and thereby modulate the histotroph composition. Beef cows (n=15 per group) were hormonally manipulated to have small (SF-SCL group) or large (LF-LCL group) pre-ovulatory follicles (POF) and corpora lutea (CL). Seven days after induction of ovulation, anim ...
