Abstract

The objective was to evaluate the efficacy of an intravaginal progesterone insert and injection of PGF2
"' for
synchronizing estrus in Holstein Friesian heifers under field condition. The heifers were divided into two groups
each consisting of eighteen (n=18) animals. Group I animals served as control and Group II animals were treated
with an intra vaginal P4 device {CIDR) for 9 days and PGF2
o: was given intramuscularly 24 hrs prior to CIDR
removal. Fixed time artificial insemination was carried outat48 and 72 hrs after Cl DR removal. The overall conception
rates obtained was 33.33 % in group I animals and 77. 77 % in group II animals treated with CIDR and PGF2alpha.
