Hyperlipaemia in ponies.

This research article investigates the disease of hyperlipaemia in ponies, presenting the case histories and clinical findings of 15 affected ponies. It suggests that the disease is mainly seen in late pregnant and early lactating mares during summer and might be triggered by a decline in nutrition when nutrient demands are high.

Research Method and Clinical Findings

• The research gathered the case histories of 15 ponies afflicted with hyperlipaemia, a condition marked by an excess of fats in the blood.
• Common symptoms of the disease observed included reduced appetite (inappetance), increased sleepiness (somnolence), muscle twitching (fasciculation), diarrhea, and swelling in the belly (ventral oedema).
• These symptoms, along with the high lipid levels in the blood, are indicative of the disease of hyperlipaemia.

Post Mortem Examinations

• Post-mortem examinations were conducted on 12 of the ponies to understand the physical changes brought about by the disease.
• The examinations revealed extensive fatty deposit (lipidosis) and blood clot formation (vascular thrombosis) in the ponies.
• These findings indicate that hyperlipaemia led to significant changes in the body, which likely contributed to the observed symptoms and possibly the death of the ponies.

Risk Factors and Hypothesis

• The research found that most cases occurred in late pregnant and early lactating mares during the summer months.
• The researchers postulate that the disease could be triggered in this group due to a decrease in nutrient intake while their nutrient requirements remain high.
• This suggests that dietary changes, such as the ones occurring during pregnancy and lactation, might make ponies more susceptible to hyperlipaemia.
• This hypothesis needs to be further studied to corroborate the findings and understand the exact relationship between the nutritional plane and the onset of hyperlipaemia.
