Observations were made on 14 mares which were non-surgically flushed on one or more occasions for recovery of embryos on Days 7-9 after ovulation. Flushing alone shortened the oestrous cycle by about 2.7 days but increased the number of mares failing to ovulate. Flushing followed by an injection of a prostaglandin analogue shortened the cycle by about 4.5 days and hence increased the frequency of ovulations. From a total of 70 flushings performed, 27 embryos were recovered and of 12 mares inseminated during the first oestrus after embryo collection, 6 conceived and foaled. The other 7 mares were used again as donors during the next seasons. They underwent a total of 21 non-surgical embryo collections and yielded 15 embryos. It is concluded that non-surgical embryo recovery and transfer provides a practical means of increasing the fecundity of valuable donor mares without depressing their fertility.
