A study was conducted to determine whether concurrent administration of vaccines for reproductive diseases and an anthelmintic, given immediately prior to estrus synchronization with a progestogen, would affect subsequent estrous response and fertili

An experiment was conducted to investigate the responses of the bovine infundibulum to noradrenaline in vitro. Twelve beef heifers were killed and examined in equal numbers during pro-oestrus and dioestrus (day 12 of the oestrous cycle). A jugular bl

Cytogenetic characteristics of ova surgically recovered from 19 first-estrous (pubertal) gilts were compared with those from 24 third-estrous gilts. Mean percentage recovery of ova was 82.1 +/- 2.9%. A total of 159 and 203 ova from first- and third-e

A study was conducted to determine whether embryos recovered from first-estrous (pubertal) and second-estrous gilts differed in survival when transferred to first- or third-estrous recipients. Embryos were recovered surgically from first- and second-

In the bovine corpus luteum (CL) phosphorylation of myristoylated alanine-rich C kinase substrate (MARCKS) protein in response to prostaglandin F2alpha (PGF2alpha) is correlated with the secretion of oxytocin. The present study was conducted to 1) ex

The aim of this study was to determine whether endogenous progesterone regulates synthesis and secretion of luteal oxytocin. In Expt 1, mature ewes (n = 5 per group) were assigned randomly to control or mifepristone (RU486) treatment groups. Ewes wer

Prostaglandin F2alpha (PGF2alpha)-induced secretion of oxytocin by the bovine corpus luteum involves the phosphorylation of a unique protein kinase C (PKC) substrate, myristoylated alanine-rich C kinase substrate (MARCKS) protein. This study was cond

Luminal epithelial cells of porcine endometrium are unresponsive to oxytocin (OT) in vitro although they express the greatest quantity of OT and receptors for OT in vivo. Therefore, the objective of this study was to determine if oxytocin acted in an
