Pattern of estrus response and conception rate following G6G and Ovsynch treatments in post-partum repeat breeding crossbred cows

Abstract

This study was designed to evaluate the efficacy of G6G treatment on pattern of estrus response and conception rate over Ovsynch treatment initiated on random days of estrous cycle in post-partum repeat breeding crossbred cows. Sixteen (n=16) cows were equally divided into two groups viz., Group 1, which received Ovsynch treatment and Group 2, which received G6G treatment. The onset of estrus in Group 1 and 2 was 48.21±1.91 and 50.12±1.84 hrs respectively. The duration of estrus in Group 1 and 2 was recorded as 19.12±1.07 and 21.47±1.18 hrs respectively. In the present study, the conception rate was 12.50 and 50.00 percent in Group 1 and 2 following Ovsynch and G6G treatments respectively. It could be concluded that the use of G6G treatment was capable of responding better in terms of estrus response and conception rate in post-partum repeat breeding crossbred cows.
