Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue of Animals, entitled “Nutraceutical Strategies for Enhancing Health and Performance in Equine”.

(1) The focus of this Issue is to highlight, through review articles and original research, innovative strategies that improve health and/or performance (growth, development, physical).

The scope is wide-ranging with respect to the nutraceuticals used as interventions. Other topics of interest include their wide and varied effects on target organ systems, the age of horses, breed, sex, and performance discipline. 

This publication will bring together researchers from around the world conducting nutraceutical study for the benefit of horses.

(2) This Issue is intended to be a significant supplement to the existing literature by publishing a combination of state-of-the-art reviews that synthesize the extant literature and research with novel findings.

We look forward to receiving your contributions.

Oral joint supplements (OJSs), specifically those containing glucosamine and chondroitin sulfate, are some of the most popular feed additives fed by horse owners. However, evidence of the efficacy of these nutraceuticals in vivo is lacking. To investigate the impacts of an OJS on equine lameness, 40 geldings (18 ± 7 yr) with chronic lameness and AAEP lameness grades between 2 and 4 (as scored by a veterinary sports medicine and rehabilitation specialist) were enrolled in the study. Horses were stratified by lameness grade, BCS, and weight, and then randomly assigned to receive a placebo powder or an OJS daily for 6 wks. Stride length measurements and lameness evaluations were performed every 2 wk. There was no effect of treatment or treatment-by-day interaction for stride length, though day affected both walk (p = 0.04) and trot (p < 0.01). Only day affected lameness grade, with the lowest average score on d28 (p = 0.04). There was no evidence of supplementation improving gait symmetry over time. As such, there is no evidence to support efficacy of the tested OJS when fed for 6 wk. These results emphasize the importance of well-controlled studies and support continued development of evidence-based management strategies for equine joint health. Full article
