The Mechanism of Action of Exogenous PGF2alpha in Clearance of Nonspecific Uterine Infections in Sheep and Pigs
… infections in sheep and pigs. Injections with Lutalyse (PGF2alpha analogue) during the luteal phase in sheep causes luteolysis; therefore, it impossible to evaluate the effects of Lutalyse independently of luteolysis. In order to cause an endogenous release of PGF2alpha without causing …
