Abstract
The objective of this study was to evaluate the breeding performance of Indonesian beef cattle (Ongole cross) as recipients for embryo transfer using Limousin embryos. As a result, the pregnancy rate was 35% (7 out of 20 cows). There was a significant difference (P<0.01) in the serum progesterone concentration between the nonpregnant and pregnant cows at the time of the embryo transfer (day 7 after the estrus). The pregnancy rate in the Indonesian beef cows was low, which may be due to their insufficient genetic quality and/or low physical conditions caused by the poor management, like a low-nutrition diet. The low progesterone concentration in the nonpregnant cows on day 7 may be associated with the failure of embryo implantation.
