	abstract = {The bovine conceptus induces an array of physiological and   biochemical responses that lead to the establishment of pregnancy.   Among the most studied of these is secretion of prostaglandin (PG)   F2alpha (F) from the uterine endometrium. Pregnancy appears to be   associated with laterations in many of the regulatory systems that cause   PGF secretion leading to luteolysis in cyclic animals. The conceptus   secretes an antiluteolytic protein (bovine trophoblast protein-1 complex   [bTP-1] that appears to induce an inhibitor of prostaglandin synthesis.   The bTP-1 antiluteolytic protein is an alphaII interferon. The   secondary effects associated with interferon-like activities (antiviral,   antiproliferative, altered gene expression, immunosuppressive) may   complement development and sustenance of the conceptus. Both ovarian CL   function and follicular activity are altered in early pregnancy.   Changes in follicular activity may reinforce the antiluteolytic signals   from the conceptus leading to maintenance of the CL. Potential   management systems to improve reproductive efficiency that are based on   supplementation with bTP-1-like molecules, controlled ovarian follicular   management, and progesterone therapy are discussed.    },
