Summary
# Equine Adiponectin and Obesity: Clarifying a Key Metabolic Link Adiponectin, an adipokine with insulin-sensitising properties, appears dysregulated in some horses with equine metabolic syndrome (EMS), yet the precise relationship between reduced circulating adiponectin and obesity in equids had not been systematically characterised. Barnabé and colleagues investigated total adiponectin concentrations across native-breed ponies with varying body conditions, using standardised obesity metrics and biochemical analysis to determine whether hypoadiponectinaemia represents an independent metabolic dysfunction or a direct consequence of excessive adiposity. The researchers identified a significant inverse relationship between total adiponectin and both body condition and adiposity measures, with obese animals demonstrating substantially lower concentrations than lean counterparts—a pattern consistent with findings in other species. These findings suggest that adiponectin dysregulation in native ponies is primarily driven by obesity itself rather than representing a separate metabolic defect, which has important implications for management: addressing weight loss in obese animals should improve adiponectin profiles and associated insulin sensitivity, offering a measurable metabolic target for monitoring the efficacy of nutritional and exercise interventions in EMS-affected individuals.

Practical Takeaways
- •Obesity assessment in native-breed ponies should consider adiponectin status as part of metabolic syndrome evaluation, as dysregulation may contribute to laminitis risk independent of insulin alone
- •Weight management and metabolic monitoring are critical preventive strategies, as insulin dysregulation occurs in all affected animals and may be linked to adiponectin abnormalities
- •Veterinarians should consider adiponectin testing alongside traditional insulin and glucose assessments when evaluating obese ponies for metabolic syndrome risk
Key Findings
- •Study investigates the relationship between total adiponectin concentrations and obesity in native-breed ponies
- •All equine metabolic syndrome-affected animals display insulin dysregulation as a core feature
- •Some animals with equine metabolic syndrome show adiponectin dysregulation and/or excessive adiposity
- •The specific relationship between obesity and hypoadiponectinaemia in equids remains unclear and requires further investigation
