Concentrations of estradiol-17β (E2), progesterone (Po), and luteinizing hormone (LH) in serum and estrone glucuronide (E1G) and pregnanediol glucuronide (PdG) in urine were determined by direct radioimmunoassay in five yearling and three adult fema

This study was conducted to investigate regulation of LH release by opioid peptides during puberal development in beef heifers. Fourteen heifers were randomly assigned to receive naloxone (opioid antagonist) i.v. at dosages of either 1 mg.kg BW-1.wk-

Autoradiography was used to quantify opioid receptors in the median eminence (ME) and preoptic area (POA) of the brain of eight heifers, and in vitro perifusion of ME and POA tissue from seven cows and heifers was used to examine the release of LHRH

The response of serum luteinizing hormone (LH) to naloxone, an opiate antagonist, and gonadotropin-releasing hormone (GnRH) was measured in cows in late pregnancy to assess opioid inhibition of LH. Blood samples were collected at 15-min intervals for

Five primiparous, 3-year-old Hereford cows suckled ad libitum , were cannulated via the jugular vein and stanchioned for 2-day sampling periods, every 14 days starting 14 days after the mean calving date. On the second day of each period, calves were
