Identifying ponies with prelaminitic metabolic syndrome (PLMS) is key to preventing laminitis. This syndrome accurately predicts which ponies are at high risk for developing the debilitating condition.

Area of Science:

  • Equine metabolic health
  • Veterinary internal medicine
  • Animal genetics

Background:

  • Clinical laminitis often results in persistent disability, highlighting the need for preventative strategies.
  • Identifying horses and ponies predisposed to laminitis can improve intervention effectiveness.
  • Previous laminitis history is a significant factor in disease recurrence and management.

Purpose of the Study:

  • To identify risk factors and develop a predictive model for laminitis in ponies.
  • To investigate the association between metabolic parameters and a history of laminitis.
  • To establish a diagnostic tool for early detection of laminitis predisposition.

Main Methods:

  • Pedigree analysis to assess inheritance patterns of laminitis.

  • Blood analysis measuring plasma insulin, triglycerides, cortisol, glucose, and free fatty acids.
  • Statistical derivation of a prelaminitic metabolic syndrome (PLMS) using metabolic proxies and clinical data.
  • Prospective monitoring of ponies following PLMS identification.

    • Main Results:

    • Previously laminitic (PL) ponies exhibited higher plasma insulin and triglyceride concentrations compared to never laminitic (NL) ponies.
    • Compensated insulin resistance was indicated in the PL group.
    • The derived PLMS model had a 78% predictive power, identifying 62 out of 160 ponies as predisposed.
    • Ponies identified with PLMS had a significantly higher odds ratio (10.4) of developing clinical laminitis when pasture starch increased.

    Conclusions:

    • The prelaminitic metabolic syndrome (PLMS) is an effective tool for identifying ponies at high risk of developing laminitis.
    • Utilizing PLMS can increase the efficiency of preventative interventions by nearly threefold.
    • The PLMS model facilitates the design of targeted interventions and may impact equine market values.
