The formulation of BotuCrio contains a lower concentration of Glycerol and, in combination with one of several amides, results in better sperm integrity, sperm viability, better post thaw total and progressive motility, as well as sperm velocty, compared to other commercially available freezing extenders.
Studies have indicated that stallion sperm frozen in BotuCrio have better fertility compared with other extenders. These very good in vitro results have been confirmed during fiel experiments to provide higher pregnancy rate after insemination.
Must ship on ice. The manufacturer states it can arrive thawed but must still be cold. If that is ok with you please choose 2nd day shipping. If you would like it to have a better chance of arriving frozen please choose Next Day Air.
