Influence of rectal massage of ovaries in anestrus buffaloes

Abstract

Heifers (9) and buffaloes (6) with the history of anestrous were subjected to per-rectal ovarian Iuassage followed by ultrasonography and blood sampling on alternate day for 25 days. During the period of study, none of the heifers or buffaloes was detected in estrus as well as plasma progesterone in both the groups on different days retnained <0.4 ng/nll which is indicative of true anestrous. NUlnber of small «5 mm), mediutTI (5-9 mnl) or large (>9 mm) follicles were not different between days and none of the animals ovulated. Plasma progesterone and nunlber of Small follicles were different (P<0.05) between the anoestrus heifers and pluriparous buffaloes. This study demonstrated differential ovarian activity in anoestrous heifers and pluriparous buffaloes. Further, repeated per-rectal ovarian nlassage does not influence ovarian activity in buffaloes.
