Manipulation of ovarian and uterine function to increase conception rates in cattle [PDF]
In cattle, embryonic and fetal losses are the major causes of reproductive failure. Losses associated with failure in the process of maternal recognition of pregnancy can amount to as much as 30%.

The Effect of PGF2α on the Expression of Sodium Dependent Vitamin C Transporters in Early vs. Mid-Cycle Corpora Lutea of Sheep [PDF]
, 2010 The corpus luteum (CL) is an ovarian structure responsible for progesterone secretion and the maintenance of early pregnancy. In the absence of pregnancy, the CL regresses in response to uterine prostaglandin PGF2α.

Control of luteolysis in the mare
, 2015 Persistent corpus luteum (PCL) is one cause of infertility in mares. However, its nature is poorly understood. Furthermore, role of oxytocin during luteolysis is not clear. A series of experiments were conducted (1) to characterize PCL and to compare PCL with interovulatoryintervals (IOIs) and (2) to evaluate the role of oxytocin during luteolysis. The
