oxytocin function in cattle

Reduction of ovarian oxytocin content from early luteal phase does not affect the corpus luteum secretory function in cattle. The corpus luteum (CL) produces oxytocin (OXT), which has been proposed to regulate the pulsatile release of prostaglandin F2alpha during luteolysis in ruminants. Description.
