Feed and Ovarian Activity of Trotting Mares in Training.

This research reports on the observable improvement in ovarian activity among Swedish trotting mares following the introduction of a balanced pellet feed, and it explores the possible interdependence of the change in diet and better reproductive health, contrasting with previous observations when the mares were mainly fed oats.

Background

• Previous observations noted that Swedish trotting mares usually had inactive ovaries after discontinuing race training. It was hypothesized that the extensive training and racing were suppressing the mares’ sexual functions.
• In more recent times, mares’ ovarian activity seemed to normalize immediately after leaving the racetrack, prompting an investigation into the causes of this improved reproductive health.
• Simultaneously, there had been changes in the mares’ diet, with a shift from predominantly oat feed to more balanced pellet feed. This observation led researchers to probe whether this dietary improvement had an impact on the mares’ ovarian activity.

Purpose and Methodology of the Study

• The study aimed to examine the association between the improved ovarian activity of mares, their rigorous training schedules, and changes in their feeding regimens.
• The research practice primarily involved systematic examinations of the ovaries of mares that were undergoing training and on different feeding programs. This scientific approach intended to establish a relationship between the observed improved ovarian functions and the nutritional content of the newer pellet feeds.

Implications of the Study

• If the findings of the study confirm that the improvement in mares’ reproductive health is linked to better nutrition provided by the pellet feeds, it raises the necessary change of diet for race mares to boost their ability for breeding post-racing.
• This research is also significant as it may debunk previous assertions that the strenuous training hinders mares’ reproductive functions.
• The study, overall, contributes to the better understanding of dietary requirements for race mares and how these can influence their health and performances, both on and off the racetrack.
