Effect of suckling on postpartum changes in 13,14-dihydro-15-keto-PGF2 alpha and progesterone and induced release of gonadotropins in autumn-lambing ewes.

Abstract

Postpartum changes in concentrations of 13, 14-dihydro-15-keto-prostaglandin F2 alpha (PGFM) and progesterone and gonadotropin-releasing hormone (GnRH) induced release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were studied in two experiments on suckled and nonsuckled autumn-lambing ewes. In both experiments, one group of ewes had… (More)
