Multiple ovulation and embryo transfer is one of the reproductivetechnologies which is important to increase animal production. In this case report, four cows were selected as donors while elevencows were selected as recipients. Both donors and recipients had undergone the same procedures and steps for multiple ovulation and embryo transfer (MOET), such as cow preparation, synchronisation and where only donor cows follow the superovulation protocol. Cows were artificially inseminated and the embryos were flushed and graded. Out of four selected cows for donor, one of them was pregnant and only two cows actuallyproduced the embryos. The recovery rate for the embryo collection was 70.1%, and from 13 embryos (including unfertilised ova), 84.6% of the embryos was classified as good quality and suitable for embryo transfer. The overall results showed that out of eight recipients, five cows were detected pregnant, a 62.5% pregnancy rate. The aim of this report is to describe the procedures aswell as the factors that affect the successful of the MOET programme.
