Dietary supplements for horses are products added to a horse's diet to provide additional nutrients that may not be sufficiently available in their regular feed. These supplements can include vitamins, minerals, amino acids, and herbal compounds. They are used to address specific nutritional needs, support general health, or enhance performance and recovery. Common types of supplements include those targeting joint health, digestive support, and hoof condition. The efficacy and safety of these supplements can vary, and their use often requires careful consideration of the horse's overall diet and health status. This page compiles peer-reviewed research studies and scholarly articles that explore the composition, usage, and impact of dietary supplements on equine nutrition and health.
PEARSON PB, SCHMIDT H.On the basis of studies with Shetland ponies it appears that a daily intake of 38 µg of pantothenic acid per kg. of body weight is adequate to permit normal growth and health in the horse.
The amount of pantothenic acid excreted by the renal pathway is influenced by the levels ingested. On the level of 150 µg daily per kg. of body weight 41 per cent was excreted in the urine whereas when the level ingested was 38 µg per kg. of body weight only 12.7 percent was excreted by the renal pathway.
The type of diet that a horse consumes is one of the most important factors determining the mineral profile and tensile strength of its hooves, so the quality and nutritional value of the supplied feed are fundamental to achieving satisfactory hoof quality. The objective of this study was to compare the differences in the mineral concentrations of sodium (Na), potassium (K), magnesium (Mg), zinc (Zn), and Iron (Fe) between two diets, namely silage and a commercial concentrate, using atomic absorption spectrometry and to determine which led to higher increases in the hoof tensile strength of ho...
Kwon YS, Jeong H, Kim J, Kim J, Chun K, Yang SK, Kim B.Osteoarthritis is a leading cause of equine lameness, yet pragmatic evidence for nutraceuticals in horses remains limited. Unassigned: We prospectively evaluated 12 weeks of daily natural eggshell membrane (NEM; 12 mg/kg, orally) supplementation in Warmblood horses with chronic lameness using a single-arm before-after design. Ten horses were enrolled and prespecified paired contrasts compared visit 3 (V3, week 12) with baseline (V1). Outcomes included rider-reported under-saddle function (walk and trot), examiner-graded lameness (rest and walk-trot composite), simple joint-angle kinematics...
Blanco-Doval A, Barron LJR, Bustamante MÁ, Aldai N.Mare milk has often been considered a food product with potential functional properties. However, the bioactive compound composition of mare milk, including vitamins and other minor bioactive compounds, as well as factors affecting this composition have scarcely been studied. Therefore, the present study aimed to characterize the changes during lactation in the content of water- and fat-soluble vitamins and total polyphenols, and the total antioxidant capacity of mare milk from semi-extensive farms. A total of 310 individual milk samples from 18 mares belonging to three commercial farms and 12...
Stoneham SJ, Tyler N, Holmes MA, Archer DC.This prospective, controlled field trial aimed to determine the effect of dietary supplementation of mares in late pregnancy with a commercial stud feed balancer on the transfer of passive immunity to their foals. Eighty-two pregnant mares on a single stud farm that were eligible for inclusion were assigned into two groups (Intervention and Control) based primarily on existing social groupings. Between 64-224 days prepartum, all mares received the same forage-based diet but mares in the Intervention group received an in-feed commercial stud feed balancer and mares in the Control group received...
Andrews KM, Berghaus LJ, Hart KA.Equine Asthma Syndrome (EAS) is a chronic inflammatory respiratory disease of adult horses. While dietary polyphenols have shown anti-inflammatory effects in human asthma, their use in equine asthma has not been studied. Objective: To evaluate the effects of a mixed polyphenol supplement on systemic and pulmonary inflammation, bronchoalveolar lavage (BAL) cytology, and clinical respiratory signs in healthy and asthmatic horses. We hypothesized that polyphenol supplementation would decrease systemic and pulmonary inflammation in both healthy and asthmatic horses and would improve BAL cytology a...
