Evaluation of dietary and management risk factors for enterolithiasis among horses in California.

This research study is about understanding the dietary and environmental factors that can increase the risk of enterolithiasis, a condition causing intestinal obstruction in horses. The study focuses on horses in California and analyzes the types of diet that can contribute to this condition.

Background of the Study

• Enteroliths or intestinal calculi are stones which result in intestinal blockages leading to colic in horses.
• This condition, also known as enterolithiasis, is common worldwide but has a higher prevalence in regions like California.
• The primary goal of this research was to uncover the dietary and environmental risk factors that could increase the possibility of this disease in horses.

Methodology

• The researchers deployed a case-control study to understand the root causes of enterolithiasis.
• The study involved comparing horses with colic from enterolithiasis referred to the University of California, Davis Veterinary Medical Teaching Hospital (VMTH), with horses having colic from other reasons.
• For the purpose of collecting data, the researchers examined patient records of 61 horses suffering from enterolithiasis and 75 control horses.
• Alongside, they collected further information through questionnaires filled out by the owners at the time of hospital admission.

Findings

• The study employed multiple logistic regression analysis to decipher the results obtained.
• The findings of the statistical analysis revealed certain factors significantly connected with enterolithiasis. These include:
  • Feeding horses with a diet consisting of more or equal to 50% alfalfa.
  • Providing less than half the diet as oat hay or grass hay.
  • Not allowing daily access to pasture grazing for horses.

Implications

• These findings suggest that changes in dietary practices and providing daily access to grazing could reduce the risk of enterolithiasis in horses.
• As this study focuses on horses in California, it would be beneficial to conduct similar research across different geographical locations to determine the applicability of these findings more universally.
