EFFECT OF REPEATED ADMINISTRATION OF PROSTAGLANDIN F_(2 alpha) (DINOLYTIC~(R)) ON THE ENDOCRINE CHANGES, OVA TRANSPORT AND EMBRYO DEVELOPMENT OF RECENTLY OVULATED SOWS

摘要

Prostaglandin F_(2 alpha) (PGF~(2 alpha)) or its analogue has been extensively used to influence various reproductive conditions such as luteolysis and abortion induction's. PGF_(2 alpha) also affects oviductal motility and ova transport (1). Furthermore, PGF_(2 alpha) has been shown to stimulate the hypothalamic-pituitary-adrenal (HPA) axis by elevating adrenocort-icotropic (ACTH) secretion (2). The objective of the present study was to investigate the effect of PGF_(2 alpha) on endocrine patterns,ova transport and embryo development of recently ovulatcd sows.
