Lipidomics and biochemical profiling of adult Yili horses in a 26 km endurance race: exploring metabolic adaptations.
Abstract: The equine lipid metabolism is activated during and after endurance exercise to provide energy in response to the metabolic and physiological changes in the body caused by prolonged exercise; however, the specific regulatory mechanisms remain controversial and identifying differential lipid metabolites associated with equine endurance is essential to elucidate these regulatory mechanisms. In this study, blood samples for lipid metabolomic analysis and biochemical indices were collected before and after a 26 km race from 12 Yili horses with different endurance performance. The biochemical results showed that: the albumin (ALB) level was significantly higher in the general group than in the excellent group before the competition, but significantly lower in the ordinary group after the competition (p < 0.05); the pre-competition alanine aminotransferase (ALT) in the excellent group was significantly higher than that of the general group (p < 0.05); and the urea nitrogen (BUN) in the general group was significantly higher than that of the excellent group after the competition (p < 0.05). The lipid metabolism results showed that a total of 1,537 lipid differential metabolites were obtained, mainly enriched in the pathways of fatty acid biosynthesis, cortisol synthesis and secretion, bile secretion, aldosterone regulation of sodium reabsorption, biotin metabolism, steroid hormone biosynthesis, and neuroactive ligand-receptor interactions. Metabolomics and biochemical correlation analyses screened PC (18:3/18:4) and PI (18:1/18:2) as potential biomarkers to identify endurance performance in Yili horses. The results of this study provide a solid foundation for improving equine racing performance and for the selection and breeding of endurance horses by providing a comprehensive reference on the mechanisms of lipid metabolism in equine endurance.

The research delves into the metabolic adaptations of adult Yili horses during a 26 km endurance race. The study collected blood samples to analyze lipid metabolites and biochemical indices, with a focus on identifying changes related to endurance. It aims to enhance understanding of equine racing performance and assist in selective breeding of endurance horses.
Methodology
- The researchers collected blood samples before and after a 26 km endurance race from 12 Yili horses. These horses had varying endurance performance. The samples were then used to conduct lipid metabolomic analysis and biochemical indices.
- They measured a number of biochemical parameters including the albumin (ALB) level, alanine aminotransferase (ALT), and urea nitrogen (BUN).
Results
- The findings showed that the albumin level was significantly higher in the general group of horses than in the excellent performing group prior to the race, but significantly lower in the ordinary group following the race.
- The pre-race alanine aminotransferase in the excellent group was remarkably higher than that of the general group.
- The urea nitrogen in the general group was significantly higher than that of the excellent group post competition.
Lipid Metabolism
- A total of 1,537 distinct lipid metabolites were detected and were primarily enriched in the pathways of fatty acid biosynthesis, cortisol synthesis and secretion, bile secretion, aldosterone regulation of sodium reabsorption, biotin metabolism, steroid hormone biosynthesis, and neuroactive ligand-receptor interactions.
- Metabolomics and biochemical correlation analyses screened PC (18:3/18:4) and PI (18:1/18:2) as potential biomarkers to identify endurance performance in Yili horses.
Conclusion
- This study provides a comprehensive reference on the mechanisms behind lipid metabolism in equine endurance, offering essential insights into endurance performance in Yili horses.
- The research lays a solid foundation for enhancing equine racing performance, selection, and breeding of endurance horses.
