ABSTRACT
Taherian M, Goli M, Karami H., Effect of oxytocin and PGF2α on
retention of fetal membranes in normal
calving Holstein dairy cows, 20(11):728-735, 2016. Effect
of intramuscular oxytocin and PGF2α minutes after spontaneous unassisted
calf delivery on retention of fetal membranes (RFM) within 12 h after calf
delivery in Holstein dairy cows is described. Cows (n=23) were injected 50 IU
oxytocin IM in 5 ml sterile solution, 23 injected 500 µg cloprostenol PGF2α IM 2 ml, and 22 controls 5ml
saline. Interactions between parity of the dam, treatment with OT or PG and
gender of calves on incidence of RFM in unassisted calves were evaluated
statistically. Findings showed no significant difference between OT, PG,
parity, or gender of calves on incidence of RFM. However, there was a decrease (P < 0.05)
in RFM in cows given PGF2α compared with controls.
Keywords: Oxytocin; PGF2α; RFM; Holstein cow.
