More then one fifth of the world’s cow population is now bred by artificial insemination. 20 million doses of semen were exported in the year of 1998 alone (Thibier M., Wagner H.G. 2002). There is an intense international import and export of semen today and the industry of artificial Insemination of cattle is constantly expanding. An even newer trend in the cattle breeding industry is the increasing phenomenon of in vitro production of bovine embryos. These embryos are also being imported and exported all over the world. The risk of transfer of bacteria and viruses, or even prions, from one country to another and one population to another is increasing and standard quality procedures are necessary. Why not take advantage of the safety thinking already in place within the human ART industry? We can learn very much from the standardised procedures that are already in place for the handling of human embryos and spermatozoa. The Nidacon range of animal products has been developed utilising our experience in the human ART industry. We take full advantage of our more than 10-years of research in human infertility when we develop optimised products for the bovine breeding industry.

This finding and the similarity between those two density gradient preparations suggests that BoviPure is a good alternative for sperm separation in bovine IVF”

This points to the possibility of using double frozen spermatozoa in bovine artificial insemination programmes and to the potential benefits of PureSperm® density gradient centrifugation for the application of cryopreserved bull spermatozoa to other biotechnological procedures such as flow cytometric sex sorting followed by re-freezing and thawing.”

“In summary, BoviPure Pro sperm treatment before AI significantly increases fertilization rates and can result in as much as an 18.5% increase in transferable quality embryos as compared to standard methods”.
