Comparison Between Transport Vials   The large number of equine embryo transfers performed at Zerlotti Equine has contributed to some different studies that have been helping us to improve our results. The objective of this small article is to inform veterinarians around the world about the importance of the vial we use to ship the embryos that we collect. We have been testing some different transport vials and holding medias. These are just two of the many pictures we took to show the difference between shiped embryos, comparing different brands of vials. This research was done with 2 identical vials, different brands. The embryos used in this research were produced by cloning process.
