With foaling season well under way, it's critical to understand the importance of "Passive Transfer"! Foals are born with no immunity, and all immunity is naturally transferred from the mare through colostrum, but sometimes the quality of the colostrum fails, or there is no colostrum, or there are other issues, and that may lead to a condition called "Failure of Passive Transfer" ("FPT"). This means that the foal is at higher risk from any environmental pathogen it encounters. It is possible to perform a plasma transfer with hyperimmunized (by choice) plasma which will offer the protection that wasn't available naturally. But what about the quality of the plasma? Could that come with a risk? The answer is definitely "yes", so care must be taken with the preparation of the plasma that is to be used. Plasvacc USA Inc. offers an insight into its own production process for the plasma they provide - quality control is important!!

Accountability in every drop. 🩸

At Plasvacc USA, we believe that transparency is the foundation of trust. Every bag of our plasma is 100% traceable back to a single, specific donor in our USDA-licensed facility.

We don’t blend. We don’t compromise. This “single-source”commitment reduces the risk of adverse reactions and ensures that the potency you see on the label is exactly what your patient receives.

Professor Aurich in this podcast discusses stallion welfare, with particular emphasis on changed that can be made to many current management methods to improve that welfare. This is certainly an area that is often sadly lacking because of long-time dogma and habits about how stallions should be housed, managed and handled.

Professor Aurich's presentation can be listened to in the links provided by the International Society for Equitation Science: https://www.facebook.com/EquitationScience/posts/pfbid031vaJcorTX2NfZaLe8uL5TJ4BTguNj9Dq3y3wrWdGopgc1GR687TyizovvUob2UPLl

Stallions are central to breeding programmes worldwide, but how often do we stop to consider their welfare beyond reproduction?

In this episode, Professor Christine Aurich joins us to discuss her latest review paper exploring the social and emotional needs of breeding stallions, and how these can be balanced alongside reproductive performance.

We unpack:
• The welfare risks of routine isolation
• Why reproductive success ≠ good welfare
• The role of early socialisation and life history
• Group housing, bachelor systems, and social contact
• Training stallions for semen collection without stress
• Challenging stigma around stallion behaviour

The discussion highlights a key message: productive breeding and positive welfare are not mutually exclusive. With the right management, stallions can have both.

Based on the paper:
Importance of the social environment for reproductive and general welfare of domestic horse (Equus caballus) stallions

𝐅𝐫𝐞𝐞 𝐒𝐞𝐦𝐞𝐧 𝐄𝐱𝐭𝐞𝐧𝐝𝐞𝐫 𝐓𝐞𝐬𝐭 𝐊𝐢𝐭𝐬!

There is no one semen extender which will work for all stallions. That has been discussed many times in by us the EquineRepro group. Botupharma USA are offering their test kits containing 5 different extenders for free, requiring only payment to cover the shipping and handling. We will put the link to the offer in the first post below, as that increases the exposure to our group members rather than adding it to this post.

Check your stallion's most suitable extender before you ship this year (and every year - they can change!!)

𝐏𝐡𝐨𝐭𝐨𝐭𝐫𝐨𝐩𝐢𝐜 𝐒𝐭𝐢𝐦𝐮𝐥𝐚𝐭𝐢𝐨𝐧 𝐃𝐚𝐲!

For those of you in the northern hemisphere who "put your mares under lights" - today is the day!! Some do it a few days earlier with American Thanksgiving, but December 1st is often used as the initial day. Onset of cyclicity will typically commence in 60-90 days with a lighting protocol - of which there are several, and we detail them and more in our article on our website a

What practical solutions are there to start mares cycling earlier in the year? This article discusses some options.

There have been many developments which have changed the course of equine reproduction, but possibly the greatest was the development of ultrasonography for early identification of pregnancy, a technique which then moved on to be used in many other aspects of the reproductive practice. Sadly, the developer of that technique, Professor Eric Palmer, has passed. While many may not know his name, his technique will live on for ever.

Vale Professor Palmer

Professor Eric Palmer 1947-2025
It is with great sadness that we learnt of the death of Professor Eric Palmer. Eric possessed a quiet and kind aura, accompanied by a vast intellect and was held in high esteem by his colleagues in France and internationally. Amongst Eric’s many pioneering innovations, the application of transrectal ultrasonography to diagnose pregnancy in the mare was arguably the most important. Since the publication of Eric’s first report in 1980, this technique has been applied globally to improve reproductive efficiency and welfare in the mare, particularly via the ability to identify twin conceptuses. In 1991, his group was the first to report first successful in vitro fertilisation resulting in the birth of a live foal and he was involved in the first cloning of valuable competition horses. The Equine Reproduction Research Unit at INRA was established at Eric’s instigation in 1981. Multiple honours were quite rightly bestowed on this amazing man and he was a foundation member of the International Symposium on Equine Reproduction as well as serving as a long standing member of its International Committee, holding the office of Chair in the mid-1990s. Aside from his research, Eric was a talented horseman, competing the offspring of his cloned horses. His intellect and pioneering spirit will be greatly missed by the equine reproduction community. Our deepest condolences to his wife and scientific collaborator Pascale and their daughters.
