[An analysis of stallion fertility based on the number of matings per heat].
Abstract: The fertility problems were studied in the herd of the English Thoroughbred horse on the Napajedla stud farm. Breeding records for the period from 1880 to 1972 were used as the starting data. The survey comprised 32 stallions. The relationship between fertility and the number of matings was calculated by the chi 2 quantity. The calculated values are highly variable. However, it is generally seen in most of the stallions that the number of matings per heat (i. e. one or several matings) had no significant influence on the pregnancy of mares and on the fertility values of the stallions. A higher variability among the stallions was found both in fertility and in the number of abortions. The evaluation of pregnancy in mares for the period from 1880 to 1972 indicates that its level was significantly higher before World War I than in the post-war period. The results are interpreted in the discussion.

This research took historical breeding records from an English Thoroughbred horse stud farm to study whether the number of matings per heat cycle impacts stallion fertility. The analysis found no direct correlation between the number matings and fertility, however, it noted differences in fertility and number of abortions among stallions. The overall fertility was higher in the pre-World War I records.
Study Background
- This research utilized historical breeding records from the Napajedla stud farm. The study period spans from 1880 to 1972, which allows for a wide range of patterns and correlates to be observed.
- The herd focused on in this study was comprised of English Thoroughbred horses, specifically 32 stallions.
Methodology
- Researchers analyzed the relationship between fertility and the number of matings per heat, using the chi-square test to measure correlation.
- The fertility studied in this context was both the potential for stallions to impregnate mares and the subsequent successful foal births.
Results
- The results of this study were consistent yet varied. The relationship between the number of matings per heat and stallion fertility showed a wide range, suggesting no significant influence.
- However, higher variability was observed amongst the stallions in terms of fertility and number of abortions (failed pregnancies). This suggests other factors may be integral in fertility rates and successful pregnancies amongst the Thoroughbreds studied.
Pre and Post World War I Fertility
- An interesting pattern was observed during the course of this study. The fertility rates were significantly higher before World War I compared to the post-war period. The cause of this fluctuation was not covered in the abstract, but perhaps the hardship and stressors associated with the wartime period may have played a contributing role.
Conclusion and Interpretation
- This research overall shows no significant influence based on the number of matings per heat on stallion fertility, albeit with considerable variability. More detailed insights from the study will be interpreted in the full research paper.
