Description PG Thesis
The study was carried out to study the efficacy of different progesterone based
estrus synchronization protocol for synchronization of estrus under controlled conditions
in NARI Suwarna ewes, and to compare the conception rate of the different progesterone
based estrus synchronization under controlled conditions. The estrus synchronization
protocol involving progesterone impregnated intravaginal sponge and CIDR along with
PMSG and PGF2? was found to be highly effective in inducing estrus response in NARI
Suwarna ewes. The study further revealed that the estrus response was found to be 100 %
in both sponge and CIDR groups. However, the time taken for onset of estrus, duration of
estrus, conception rate did not appear to be influenced by the type of progesterone
impregnated intravaginal device. It can be concluded that conception rate of 90-100 %
can be obtained by using progesterone impregnated intravaginal devices in NARI
Suwarna ewes provided they are maintained under good manage mental practises.
