Abstract: The aim of this research is to produce twin pregnancies in Simmental cows through AI and Embryo transfer (ET). This study performed AI and ET of an additional embryo on the 7th day after insemination using 16 Simmental cows at. Andalas University Animal Husbandry and Breeding Center (BPTU-HPT). Of the 16 cows were treated using a combination of AI and ET resulting of a pregnancy rate (Conception Rate) of 37.5 %. Half the Simmental cattle to AI and ET had single offspring, 50%, 16.6% had a healthy twin birth, 16.6% an abortion and the remaining 16.6% had twins that died soon after birth. Only one of 6 cows who became pregnant was successful in producing healthy twins.
