This week's "Snippet" from the 8th International Symposium on Stallion Reproduction looked at donkey semen cryopreservation with different permeable cryoprotectants and at different concentrations. Donkeys can be challenging, so additional information about "best protocols" is of great benefit!

This week's "Snippet" from the 8th International Symposium on Stallion Reproduction looked at the effect of different protocols on post-thaw characteristics of epididymally-sourced s***m. Harvesting s***m from the epididymis is a practical solution for preservation of genetics following an unanticipated death or a planned castration of a stallion.

This week's "Snippet" from the 8th International Symposium on Stallion Reproduction looked at the impact that post-thaw s***m quality had on ICSI outcomes when frozen semen was the s***m source.

This week's "snippet" from the International Society for Equine Reproduction presents a summary of an abstract presented at the 2025 International Symposium on Stallion Reproduction which compared fertility markers at different stages of development in the c**t with a view to possible determination of future fertility.

Predicting Breeding Soundness in Colts has significant potential financial benefit for the breeder when deciding to keep them intact or not.

EHV-1 Veterinary Clinic Questionnaire

EHV-1 vaccination protocols vary by region and individual. We have been asked by a published researcher known well to us to present this questionnaire, which is being used for a legitimate University-based research project. Answers are anonymous and your participation is appreciated.

Thank you.

Ever wondered about common causes of declining fertility in older stallions? The latest "ISSR Snippet" (courtesy of the International Society for Equine Reproduction) is available on our website!

Investigate the reasons for fertility decline in breeding stallions and the significance of management in reproductive success.

Today, we wish safety and happiness to one of the most important sectors of the equine reproductive world - the veterinarians! Without veterinarians, we would not have research, we would not have newly developed techniques and products, and we would not have the success that we have in the world of equine reproduction!

From Equine-Reproduction.com, LLC, we send those wishes generally, and in particular to the many veterinarians whom we have met, who have befriended us, and who have helped us along the way!

We hope you all have a lovely World Veterinary Day!
