The aim of the studies was the collection, splitting and transfer of halves of equine embryos in order to obtain monozygote twins. Experiments were carried out on 27 mares including 19 Polish pony and 8 heavy-type mares. Out of the total number of 134 collections, 55 (41%) embryos were obtained: on days 5.5-6.5 after ovulation, 12 embryos were collected; on day 7, the number was 32; and on day 8, there were 11 embryos. Among the embryos obtained there were 8 morulas, 11 early blastocysts and 36 blastocysts. Ten embryos were split into halves, 14 of which were transferred non-surgically and 2 using surgery in the flank. None of the transferred embryo halves resulted in pregnancy. From among 16 control mares to whom whole embryos were transferred 10 were found pregnant on day 20 and 7 of them gave birth to healthy foals.
