Reproductive performance of buffalo-cows with various synchronization protocols in kampar regency of Riau province

Abstract

The aim of this research was to compare two estrus synchronization treatments with no estrus synchronization on estrous performance, pregnancy rate and calving rate in buffalo-cows in Kampar district. A total of 60 buffalo-cows from farming communities in the villages of Tanjung, Taratak, and Salo, Kampar Regency. Variations of the estrous sync protocol included PGF2α-PGF2α and GnRH-PGF2α administered as treatments. The controls used were without the use of hormonal sync protocol. The parameters observed were the intensity of estrous, estrous percentage, onset of estrous, duration of estrous, pregnancy percentage, calving rate, duration of pregnancy, and birth weight. The results showed that there were differences [p <0.05] estrous intensity, estrous percentage [100%], estrous velocity [30.8 hours to 2.5 hours], and duration of estrous [18.6 hours to 6.5 hours]. This study concluded that the synchronization protocols of the combination of GnRH and PGF2α in post-partum buffalo-cows in Kampar Regency resulted in high estrous intensity, faster estrous appearance, and faster estrous duration.
