Abstract
The efficacy of estrus synchronization for improving the fertility and fecundity was
studied in 428 non-descript goats in Kanchipuram district (Tamil Nadu) selected based on
clinical and ultrasound examination for synchronization. Non pregnant does were inserted
with intravaginal progesterone sponge containing 300 mg of progesterone on day 0 and
administered Inj. Cloprotenol sodium (Pragma) 125μg on day 10. The sponge was removed
on day 11 of insertion followed by intramuscular injection of 200 I.U. of eCG (Inj.Folligon).
Timed Artificial Insemination was done twice at 12 and 24 h interval using Tellicherry frozen
semen. Among the synchronized does,359 does were confirmed pregnant by 30-45 days
post insemination using transrectal ultrasonography with a conception rate of 83.87% and
fecundity rate of 2.038. The study concludes that the progesterone based intravaginal sponge
in combination with eCGcan be effectively used for estrus synchronization programme to
improve conception rate and fecundity in non-descript goats at farmers flocks.
