متن کاملEffect of oxytocin infusion on luteal blood flow and progesterone secretion in dairy cattle
The objective of this study was to investigate the effects of oxytocin infusion on corpus luteum (CL) function during early to mid-diestrus by measuring luteal size (LS) and luteal blood flow (LBF) along with plasma levels of progesterone (P4) and prostaglandin metabolites (13,14-dihydro-15-keto-prostaglandin F(2α), PGFM). On day (D) 7 of the estrus cycle (D1 = ovulation), seven cows received 1...
