Article Synopsis
- Insulin dysregulation (ID) is a critical aspect of equine metabolic syndrome that can occur in horses without obesity, highlighting the need for testing beyond just breed and body condition.
- A study assessed 62 non-obese stock-type horses to determine the prevalence of ID and explored the correlation between neck measurements and ID, finding only 4.8% had ID.
- The study revealed some differences in insulin and glucose levels between mares and geldings, but found only a weak relationship between neck measurements and glucose response post-insulin test, suggesting limited predictive value for neck morphology in assessing ID risk.
In the United States, there is little clarity on the qualifications and availability of equine nutritionists. Currently, no regulatory body exists for formal credentialing outside of veterinary medicine. Most equine nutritionists are not veterinarians but do have advanced scientific degrees (Master of Science and/or Doctor of Philosophy) in the field of Animal Science.

Objective: To test the effects of single doses of black tea, cranberry, orange peel and ginger extract on markers of oxidative stress and antioxidant status following exercise in horses.
Exercise-induced increases in inflammatory cytokines in muscle and blood of horses.
Equine Vet J Suppl
November 2010
Reasons For Performing Study: Studies have demonstrated increases in mRNA expression for inflammatory cytokines following exercise in horses and have suggested those markers of inflammation may play a role in delayed onset muscle soreness. However, measurement of mRNA expression in white blood cells is an indirect method. No studies to date have documented the cytokine response to exercise directly in muscle in horses.

Hypothesis: Training and/or ulcers alter the feed intake (FI) and hormonal and/or biochemical (active ghrelin, leptin, glucose, insulin and cortisol) responses to acute high intensity exercise.
Methods: Eight Standardbred mares underwent 3 interval exercise tests (IET) and 3 parallel control tests (CON) before (IET1) and after 8 weeks of training (IET2) and after treatment for gastric ulcers (IET3).
