Summary
# Editorial Summary Artificial insemination of mares across Europe has expanded considerably over recent years, yet adoption of chilled and frozen semen remains surprisingly limited—a gap the authors attribute largely to persistent doubts about efficacy relative to natural breeding and, critically, inconsistent semen quality that fails to deliver acceptable pregnancy rates and return on investment. This review synthesises current European breeding practices with evidence on semen preservation technologies, revealing a nuanced adoption pattern: chilled semen dominates amongst sport mares and non-classified populations, whilst frozen semen is increasingly favoured in dedicated breeding programmes, reflecting different economic and logistical pressures across these sectors. The authors emphasise that reliable assessment protocols for stallion semen quality are essential to bridge the gap between theoretical potential and practical outcomes, as the premium pricing of quality semen doses demands demonstrably superior fertility outcomes to justify their use over natural service. For practitioners involved in breeding programmes, the implication is clear: the profitability and credibility of artificial insemination hinge not merely on technological capacity but on rigorous quality control and honest marketing of semen characteristics—addressing the reputational damage from poor-quality doses would likely accelerate European adoption of these technologies, particularly in breeding operations where controlled genetics and disease management justify higher input costs.

Practical Takeaways
- •If considering AI for mares, understand that semen quality assessment tools are available but actual product quality from commercial sources often underperforms; verify fertility records before committing to expensive semen purchases
- •Sport and breeding mare operations show different adoption patterns—sport mares favor chilled semen while breeding operations increasingly use frozen semen; choose based on your specific breeding goals and budget
- •The poor reputation of AI semen in Europe is partly justified by inconsistent pregnancy rates; expect lower conception rates than natural breeding and budget accordingly
Key Findings
- •Artificial insemination programs in Europe have been gaining popularity over several years, but chilled or frozen semen use frequency remains low
- •Chilled semen use is increasingly popular in sport mares, while frozen semen adoption is rising in breeding mare populations
- •Semen quality often deviates from expectations, resulting in unsatisfactory pregnancy rates that reduce profitability of AI programs
- •Negative perception of packaged insemination dose effectiveness compared to natural insemination remains a barrier to adoption
