Effect of Intense Exercise on the Level of Bacteroidetes and Firmicutes Phyla in the Digestive System of Thoroughbred Racehorses.
Abstract: Exercise significantly affects the body of both animals and humans, including the composition of the digestive microbiome. This study aimed to determine the changes in the composition of the most numerous bacterial phyla (Firmicutes and Bacteroidetes, as well as the level of the family) in the digestive system of horses under the influence of physical effort. The study included a group of 17 Thoroughbred racehorses at the age of 3 years, fed the same forage, from whom feces samples were collected individually before and 48 h after physical effort. The obtained samples were subjected to DNA isolation and RT-PCR analysis. The results showed a significant increase in the level of both phyla after exercise compared to the state before physical effort; there were no such differences in the level of facultative aerobes, i.e., the family (although a decreasing tendency was found after exercise). In addition, the analysis of the level of the studied phyla indicates individual differences in horses' response to the effort.

The research paper presents a study on the impact of intense physical activity on the composition of the most abundant bacterial phyla named Firmicutes and Bacteroidetes, in the digestive system of Thoroughbred racehorses.
Research Objective and Methodology
- The primary purpose of the research was to observe how intense physical activity could potentially change the composition of the gut’s most populous bacterial phyla (Firmicutes and Bacteroidetes) in Thoroughbred racehorses.
- This study encompassed a group of 17 Thoroughbred racehorses, all aged 3 years and fed the same diet.
- Feces samples were obtained from the horses individually, before and 48 hours after physical exercise.
- The collected samples were then subjected to DNA isolation and Reverse Transcription Polymerase Chain Reaction (RT-PCR) analysis to measure and compare the bacterial levels before and after physical exertion.
Research Findings
- The research results disclosed a considerable increase in the Firmicutes and Bacteroidetes phyla levels after the horses underwent intense exercise, compared to their levels before the physical exertion.
- However, there were no observable changes in the levels of the facultative aerobes, belonging to a particular bacterial family, regardless of the downward trend noticed after exercise.
- The researchers also noted individual differences in horses’ response to the effort, implying that physical exertion affected horses differently, resulting in a variance in the level of the studied phyla among the individual subjects.
Conclusion
- This research significantly contributes to the understanding of how intense exercise influences the composition of the digestive microbiome in Thoroughbred racehorses.
- The findings might provide valuable insights for horse owners, trainers, and veterinary professionals to optimize their care, training protocols, and dietary planning for racehorses.
- The observed individual differences underscore the need for personalized monitoring and care approaches for each horse.
