Semen Microbiome Influence on the Mare Uterine Microbiome

Posted: | September 20, 2026

Semen Microbiome Influence on the Mare Uterine Microbiome While semen-uterine microbiome interactions have been described in humans, equivalent data in horses was absent. Using a cross-species insemination model, this study investigated whether the male seminal microbiome influences the mare uterine microbiome and whether post-breeding microbiome composition affects embryo recovery. Study Design: 22 fertile mares inseminated with raw semen… Read More: Semen Microbiome Influence on the Mare Uterine Microbiome »

Updated Foaling Prediction Article

Posted: | July 25, 2026

Although the foaling season in the northern hemisphere is almost over, it’s about to start in the southern hemisphere, so there’s always someone foaling somewhere. With that in mind, our foaling prediction article is now updated! We’ve added some information about equipment newly available – particularly the C6 Evos foaling system (www.foaling-alarm.com) – and fine-tuned some of the… Read More: Updated Foaling Prediction Article »

Predicting Foaling in the Mare

Posted: | July 21, 2026

Predicting Foaling in the Mare: What Actually Works Kathy St. Martin and Jos Mottershead Waxing: The Least Reliable Sign There are many signs predicting foaling in the mare: softening of the tail head and vulva, enlargement of the udder, subtle changes in body shape, occasional shifts in disposition, and “waxing”—the appearance of wax-like droplets on the ends of… Read More: Predicting Foaling in the Mare »

Stallion Dismount Latency and Pregnancy Rates

Posted: | July 11, 2026

Stallion Dismount Latency and Pregnancy Outcomes in Thoroughbred Horses In Thoroughbred natural service breeding, dismount semen — residual urethral semen collected after copulation — is routinely used as a proxy for ejaculate quality. This study investigated whether the duration a stallion remains mounted post-ejaculation (stallion dismount latency) influences both dismount sample composition and pregnancy outcomes. Study Design: 62… Read More: Stallion Dismount Latency and Pregnancy Rates »

Prolonged Storage of Post-thaw Semen

Posted: | July 4, 2026

Storage Conditions Affecting Prolonged Storage of Post-thaw Semen Field-based use of cryopreserved stallion semen is often limited by the equipment and expertise required for on-site thawing. Thawing centrally, then achieving prolonged storage of post-thaw semen and shipping it in a cooled state could simplify artificial insemination programs at locations remote from the laboratory or center, but optimal post-thaw… Read More: Prolonged Storage of Post-thaw Semen »

Protocol for frozen semen insemination in mares

Posted: | May 12, 2026

Timing Protocol Modification for Frozen Semen Insemination in Mares There are in use a variety of protocols for frozen semen insemination. This research compares the results from several currently used with those from a new timing protocol. Background: There is a growing demand for use of frozen semen in equine artificial insemination practices Classic protocols rely on time-intensive… Read More: Protocol for frozen semen insemination in mares »

Seminal Plasma Impact on Foal Growth

Posted: | April 18, 2026

Is there a Seminal Plasma Impact on Foal Growth? This study investigated the downstream developmental consequences of seminal plasma (SP) exposure — or its absence — at the time of breeding, examining both placental gene expression and seminal plasma impact on foal growth trajectories over the first two years of life. Background & Purpose: SP proteins serve key… Read More: Seminal Plasma Impact on Foal Growth »

Uterine Interference Effect on Reproductive Function in the Mare

Posted: | December 5, 2025

The Effect of Uterine Interference on Reproductive Function in the Mare An unpublished manuscript written in 1976 by John R Newcombe and W E Allen, Royal Veterinary College University of London Introduction It has been shown in several recent reports that irrigation or infusion of the uterine lumen of the mare during the luteal phase of the oestrous… Read More: Uterine Interference Effect on Reproductive Function in the Mare »
