Effects of a supplement containing chromium and magnesium on morphometric measurements, resting glucose, insulin concentrations and insulin sensitivity in laminitic obese horses.

The research article is a study on the effects of a supplement with chromium and magnesium on laminitic obese horses with an evaluation of physical measurements and insulin sensitivity as indicators. However, the supplement did not show significant changes in the subjects.

Introduction

This study investigates the effects of chromium and magnesium, supplemented in the diets of obese horses previously suffering from laminitis, which is a painful condition affecting the horse’s hoof. Obesity and insulin resistance are established risk factors for this detrimental condition. The idea is that supplements rich in chromium and magnesium might help to improve insulin sensitivity. The experiment includes different measurements and tests that relate to the horse’s physical state and insulin indicators.

Methodology

• The researchers involved a total of 14 horses in the study. Out of them, 12 were formerly laminitic and obese, who were then randomly divided into two groups – treatment and control, each containing 6 horses.
• Additionally, 2 obese horses diagnosed with clinical laminitis were included only in the treatment group.
• The horses in the treatment group were given 56 g of a supplement, along with 0.25 kg of oats once daily for a timeline of 16 weeks. The chosen supplement was a blend of chromium (5 mg/day as yeast), magnesium (8.8 g/day as oxide/proteinate), and other nutraceuticals.
• To monitor the insulin sensitivity, insulin-modified frequently sampled intravenous glucose tolerance tests were executed at 0, 8 and 16 weeks, while the results were assessed by minimal model analysis.
• Morphometric measurements of the horses were recorded alongside. Importantly, horses were kept unexercised throughout the study.

Results

• Prior to the commencement of the study, hyperinsulinaemia, a condition characterized by excessive levels of insulin in the blood, was found in 12 out of the 14 participating horses.
• However, due to persistent pain, the data from one mare with clinical laminitis was excluded.
• As per the results, there wasn’t any significant change noticed over time in the measurements and variables examined in the horses, excluding the resting insulin concentrations that showed an increase.
• The overall health status of the participating equids remained unchanged according to the records.

Conclusion

The evaluation revealed that the supplement containing chromium and magnesium didn’t alter the morphometric measurements, blood variables, resting insulin concentrations, or insulin sensitivity in the laminitic obese horses. Considering this, further research is needed to unearth the potential uses of supplements containing chromium and magnesium in horse diets and understand their impact better.
