Maternal recognition of pregnancy in sheep, cattle and goats involves physiological
mechanisms that result in protection of corpora lutea from luteolysis by modification or …

Maternal recognition of pregnancy in domestic farm animals evolved as a physiological
mechanism by which the conceptus inhibits luteolysis through alteration in endometrial …

Sheep conceptuses secrete a protein, oTP-1, between Days 10 and 21 of gestation which is
responsible for establishment of pregnancy. oTP-1 inhibits uterine production of luteolytic …

Sheep conceptuses secrete a protein, ovine trophoblast protein-1 (oTP-1), between days 10
and 21 of gestation, that is responsible for establishment of pregnancy. oTP-1 inhibits …

The effects of administration of progesterone and oestradiol on ovine endometrial oxytocin
receptor concentrations and plasma concentrations of 13, 14-dihydro-15-keto prostaglandin …

Interferon tau (IFNτ), secreted by trophectoderm of sheep, cow and goat conceptuses
(embryo and associated membranes), is the pregnancy recognition signal. The 172 AA …

Oxytocin receptors were measured in myometrium and intercaruncular endometrium of cows
during pregnancy and parturition. Concentrations of estradiol-17β, estrone, and …

Nature and potential functions of chemical signals involved in the process of pregnancy
recognition in cattle are discussed. The array of prostaglandins, steroid metabolites, and …

The corpus luteum is composed of two distinct steroidogenic cell types, both of which
contribute significantly to the total progesterone secreted during the luteal phase of the …

In ruminants, the corpus luteum (CL) of early pregnancy is resistant to luteolysis.
Prostaglandin (PG) E 2 is considered a luteoprotective mediator. Early studies indicate that …
