Effect of Exogenous PGF2α and Oxytocin on Postpartum Anestrus and Uterine Involution in Kundhi Buffaloes
Journal Title: Journal of Animal Production Advances - Year 2013, Vol 3, Issue 4
Abstract
A study was designed to evaluate the effect of Prostaglandins(PG)F2α (Cloprostenol) and oxytocin on postpartum anestrus and uterine involution of Kundhi buffaloes. Total 30 multiparous Kundhi buffaloes of similar parity from potential farm in the vicinity of Tandojam city were selected. These animals were divided into three groups i.e. I, II and III having 10 numbers of animals in each group. The buffaloes of group I were treated with 2ml of PGF2α (0.150 mg Cloprostenol) intramuscularly , the buffaloes of group II was given 2ml of oxytocin (100 I.U.) intramuscularly and the buffaloes group III were treated as control group and administered 2ml of normal saline intramuscularly immediately after starting of labor pains. The time required for expulsion of fetal membranes, uterine involution and occurrence of first postpartum estrus were recorded in all groups. Significantly (p<0.01) early expulsion of placenta was observed in group I (3.1 ± 0.3 hrs) compare to group II (4.45 ± 0.5 hrs) and group III (6.3 ± 0.67 hrs). Time taken for completion of uterine involution was significantly (p<0.01) shorter in group I (29.4 ± 1.74 days) than group II (34.3 ± 2.20 days) and group III (37.8 ± 1.54 days), however, no significant difference between group II and III was found. The mean (± SEM) for postpartum estrus period in groups I, II and III were 70.6 ± 8.02, 82.5 ± 9.82 and 104.0 ± 6.72 days respectively. Significantly (p<0.05) earlier estrus was observed in PGF2α treated animals (group I) than groups II and III. The percentage of animals showed the signs of estrus in groups I, II and III were 80, 60 and 50% respectively. It was concluded that administration of PGF2α and oxytocin in postpartum buffaloes accelerate the process of uterine involution, reduce the time period of first postpartum estrus and induce early expulsion of fetal membrane in Kundhi buffalo.
