Abstract
This study was carried out to determine the
effect of supplementation of vitamin A along
with Ovsynch protocol on the conception rate
in repeat breeder cows Sixty repeat breeder
cows selected were equally divided into Group
I, II (Treatment groups) and Group III (Control
group). The group I cows were treated with
Ovsynch protocol. Group II cows were administered
Vitamin A (120000 IU) along with first
GnRH injection of Ovsynch protocol. Group III
(control) cows were inseminated during the
observed estrus. The conception rate was higher
in group II (70.00 per cent). From the study, it
was concluded that vitamin A supplementation
along with Ovsynch protocol could be used to
improve the fertility in repeat breeder cows.
