ABSTRACT
Shukla MK, Garg A., Effect of prostaglandin
E2 on estrus and synchronization in
buffaloes, Onl J Vet Res., 28 (11): 775-777, 2024. Four
groups of 10 healthy lactating 4-6 month Murrah
buffaloes were given 25mg intramuscular prostaglandin E2, 10mg intra uterine suppository,
10mg intra vulvar sub mucosa and controls 2 ml intravenous saline. Compared
with controls, prostaglandin increased (P < 0.05) estrus ~8%, conception
3-4% and reduced (P < 0.05) days to estrus ~3-4% but only in those given
suppositories. The percent of animals responding to treatment and time of
estrous induction after second dose by any route were not significantly
different. However, conception rates were 37.5 by intramuscular, 42.86 vulva
and 50% by uterus routes. Findings suggest that vulva or uterus may be more efficient
routes of administration.
Key
words: Prostaglandin E2, Murrah buffalo, subestrus, estrus, synchronization.
