Progesterone levels and days to luteolysis in mares treated with intrauterine fractionated coconut oil
(2016-01-14)
Intrauterine plant oil infusion, including fractionated coconut oil, has been previously found to be a safe, inexpensive, and reversible method of prolonging the luteal phase in mares when administered on Day 10 of the ...
Oestrogen, Progesterone and Oxytocin Receptors and COX-2 Expression in Endometrial Biopsy Samples from the Induction of Ovulation to Luteolysis in Llamas (Lama glama)
(Wiley-blackwell Publishing, Inc, 2013-02)
Endometrial expression of oestrogen (ERa), progesterone (PR) and oxytocin receptor (OR) and cyclooxygenase-2 (COX-2) was evaluated from the induction of ovulation to luteolysis in llamas. Ovarian activity was daily ...
Luteal Function and Follicular Growth Following Follicular Aspiration During the Peri-Luteolysis Period in Bos indicus and Crossbred Cattle
(Wiley-Blackwell, 2012-04-01)
Follicular estradiol triggers luteolysis in cattle. Therefore, the control of follicle growth and steroidogenesis is expected to modulate luteal function and might be used as an anti-luteolytic strategy to improve embryo ...
Maintenance or regression of the corpus luteum during multiple decisive periods of bovine pregnancy
(Brazilian Coll Animal Reproduction, 2016-07-01)
In ruminants, there are specific times during the estrous cycle or pregnancy when the corpus luteum (CL) may undergo regression. This review has attempted to summarize the physiological and cellular mechanisms involved in ...
Partial luteolysis during early diestrus in cattle downregulates VEGFA expression and reduces large luteal cell and corpus luteum sizes and plasma progesterone concentration
(2020-12-01)
Our objectives were to investigate potential changes in the size of steroidogenic large luteal cells (LLC) during partial luteolysis induced by a sub-dose of cloprostenol in early diestrus and to determine transcriptional ...
Direct effect of PGF2 alpha pulses on PRL pulses, based on inhibition of PRL or PGF2 alpha secretion in heifers
(ELSEVIER SCIENCE INCNEW YORK, 2012)
The relationships between PRL and PGF(2 alpha) and their effect on luteolysis were studied. Heifers were treated with a dopamine-receptor agonist (bromocriptine; Bc) and a Cox-1 and -2 inhibitor (flunixin meglumine [FM]) ...
Luteal changes after treatment with sub-luteolytic doses of prostaglandin (cloprostenol sodium) in cattle
(Elsevier B.V., 2015-02-01)
This study characterizes the physiological and morphological changes related to partial luteolysis in bovine corpus luteum (CL) after challenges with sub-doses of cloprostenol sodium on Day 6 (D6) of the estrous cycle. ...
