AUGMENTATION OF FERTILITY BY USING HERBAL AND HORMONAL PROTOCOL IN POSTPARTUM ANESTRUS COWS.

Abstract

The present study evaluated the fertility response and serum progesterone changes in 18 postpartum anestrus
(>60 days) cows treated under field conditions with Estrona feeding @ 125g/day/animal for four days (group II; n=6);
CIDR-Synch protocol (group III; n=6) and an untreated Control (group I; n=6). The animals were observed for estrus
signs and inseminated. The estrus induction rates in group I, II and III were 16.66, 66.66 and 100.00%, respectively
with conception rates of 0.00, 50.00 and 66.66%, respectively. The mean serum progesterone concentration (ng/ml)
before (0th day) and after (30th day) treatment increased insignificantly (P>0.05) in group II and significantly (P<0.05)
in group III but the progesterone on 30th day of treatment compared to other two groups was significantly low in group-
I cows. It may be concluded that the feeding of Estrona powder and CIDR-Synch protocol improved estrus induction
and conception rates in postpartum anestrus cows.
