Donkeys exhibit higher plasma leptin concentrations than horses, a key appetite regulator. This finding is linked to their increased predisposition to hyperlipemia and correlates with body condition score.

Area of Science:

  • Veterinary Medicine
  • Animal Physiology
  • Endocrinology

Background:

  • Donkeys are more susceptible to hyperlipemia than horses.
  • Anorexia is a common symptom of hyperlipemia in donkeys.
  • Leptin, a protein from fat tissue, regulates appetite in mammals.

Purpose of the Study:

  • To investigate if donkeys have higher plasma leptin concentrations than horses.
  • To explore the relationship between leptin, triglycerides, glucose, insulin, and body condition score in donkeys.

Main Methods:

  • Blood samples were collected from 50 donkeys and 25 horses.
  • Leptin, triglycerides (TGs), glucose, and insulin were measured.
  • Donkeys were categorized by body condition score (BCS): lean, normal, and overweight.

Main Results:

  • Donkeys showed significantly higher plasma leptin and TG levels compared to horses.
  • Overweight donkeys had the highest leptin and TG concentrations.
  • Leptin, TGs, glucose, and insulin levels positively correlated with BCS in donkeys.

Conclusions:

  • Donkeys possess higher plasma leptin concentrations than horses.
  • Leptin levels in donkeys are correlated with their body condition score.
