Luteal function and follicular growth following follicular aspiration during the peri-luteolysis period in bos indicus and crossbred cattle

, 2012
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 survival.

INTERFERÓN TAU EN LA VENTANA DE RECONOCIMIENTO MATERNO EMBRIONARIO BOVINO INTERFERON TAU IN THE BOVINE MATERNAL-EMBRYONIC RECOGNITION WINDOW

Revista U.D.C.A Actualidad & Divulgación Científica, 2010
El reconocimiento materno embrionario bovino es uno de los eventos de mayor importancia en la reproducción. Este proceso está regulado por múltiples señales celulares y endocrinas, entre el embrión, el endometrio y el cuerpo lúteo, que constituye la ...

Time related changes in luteal prostaglandin synthesis and steroidogenic capacity during pregnancy, normal and antiprogestin induced luteolysis in the bitch

, 2009
In nonpregnant and pregnant dogs the corpora lutea (CL) are the only source of progesterone (P4) which shows an almost identical secretion pattern until the rapid decrease of P4 prior to parturition.

A Novel Microencapsulated Bovine Recombinant Interferon Tau Formulation for Luteolysis Modulation in Cattle

Biomolecules
Early embryonic loss is a major cause of reproductive inefficiency in cattle, primarily due to premature luteolysis. Interferon tau (IFN-τ), secreted by the trophoblast, plays a critical role in maternal recognition of pregnancy by maintaining corpus ...

Relationship between the timing of prostaglandin-induced luteolysis and effects on the conceptus during early pregnancy in mares

, 2012
To advance the understanding of early pregnancy and pregnancy failure in horses, this study determined how luteolysis induced by cloprostenol (an analogue of prostaglandin F2α) affects conceptus development. Mares were injected on Days 12, 14, 16 or 18

The luteolytic effect and pregnancy rate of luprostiol, administrated via different routes and various doses in heifers [PDF]

Eurasian Journal of Veterinary Sciences
In this study, the luteolytic effect and pregnancy rate of Luprostiol administrated via different routes and various doses in heifers were investigated. Animals were divided info three experimental groups, each inc!uding 5 heifers.

Bovine luteolysis: intracellular signals [PDF]

, 2007
: The corpus luteum is a transient gland that produces progesterone during a period of time that is determined by the length of gestation. When there is no gestation the corpus luteum undergoes regression, a process commonly known as luteolysis.

Induction of transient functional luteolysis in cyclic sheep by a 3β-hydroxysteroid dehydrogenase inhibitor

, 1984
The mechanism by which prostaglandin F(α) terminates luteal function in the sheep is unclear even though it is used extensively in animal husbandry. At the time of luteal regression, a decrease in 3β-hydroxysteroid dehydrogenase (3β-HSD) activity is ...

Molecular mechanism of anti-luteolysis during the maternal recognition of pregnancy in cows [PDF]

Eurasian Journal of Veterinary Sciences
Maintenance of secretion of progesterone from the ovarian corpus luteum (CL) is essential for establishment of pregnancy in cows. The luteolytic prostaglandin (PG) is PGF2ot in cows causing regression of the corpus luteum and cessation of progesterone ...
