Effect of intra vaginal progesterone pessaries and PMSG on fecundity rate in Malabari goats

Abstract

Oestrus was synchronized in Malabari goats using 45 mg Fluorogestone Acetate (FGA group; n=l4) or 60 mg Medroxy
Progesterone Acetate (MAP group; n=l4) intra vaginal sponges or Controlled Internal Drug Release (CIDR group n=l2) device
containing 0.332 g natural progesterone. These intra vaginal sponges or devices were kept in situ for 18 days in all 3 groups and 600
I.U. PMSG was administered intra muscularly to all the does at the time of sponge or CIDR removal. Breeding at induced oestrus was
done by natural service or A.I. at 48 and 60 hours of sponge or CIDR removal. This study indicated that the fecundity in Malabari
goats could be improved and the incidences of twins and triplets could also be artificially increased by oestrus synchronization
procedures.
