Non-surgical recovery of bovine embryos

A simple one-way cannula technique for non-surgical recovery of bovine embryos has been described. The collector was very reliable, stable, and easy to use. It could be guided through cervix and without damage to the genital tract into both uterine horns on all attempts. Ninety-six per cent (96%) of the flushing medium was recovered. Bleeding occurred rarely. The post-flushing reproductive performance was satisfactory. An average of 4.1 eggs per dairy cow were recovered yielding a recovery rate of 46%. The method was performed under farm conditions with and without the use of a chute or stanchion. Several general practitioners have used the method with success after a brief training period. Good manipulative skills were a prerequisite for good results.
