Equine Metabolic Disorder Model Development
BioVenic provides equine metabolic disorder model development services for the characterization of in vivo models of metabolic diseases affecting horses for feed additive evaluation, nutritional research, and disease mechanism studies. Our platform covers the major equine metabolic disorders including equine metabolic syndrome (EMS), Cushing's disease (PPID), recurrent rhabdomyolysis (RER), polysaccharide storage myopathy (PSSM), and osteochondrosis. We support comprehensive model validation, and biomarker evaluation spanning immunological, biochemical, and multi-omics (metabolomic, proteomic, microbiome) analyses.
Background
Metabolic disorders are prevalent among modern horse breeds. A few common equine metabolic disorders include equine metabolic syndrome, Cushing's disease, recurrent equine rhabdomyolysis, polysaccharide storage myopathy, and osteochondrosis. While these disorders have distinct causes, they are all either triggered or exacerbated by excessive consumption of starch and sugar. The development of equine models will provide valuable insights into the underlying mechanisms of equine nutrient metabolic disorders. Additionally, these models will aid in the formulation of effective nutritional strategies and innovative therapies aimed at enhancing equine health and performance.
Equine Metabolic Disorder Model Development
- Development of Gene-Induced Equine Metabolic Disorder Models
Certain metabolic disorders, such as equine metabolic syndrome, often have a genetic predisposition. Type 1 PSSM is caused by a genetic mutation in the GYS1 gene. With our genetic testing platform, equine nutrition researchers can analyze genes associated with metabolic disorders. Our omics solutions aid in identifying suitable horses as research models and investigating the effects of gene therapy or nutritional tools on metabolic disorders.
- Development of Diet-Induced Equine Metabolic Disorder Models
Horses traditionally thrived on fermentable forage carbohydrates, but their diets have been supplemented with starch and sugar-rich grain meals for additional calories, protein, and micronutrients. However, consuming these starch-rich meals can lead to digestive and metabolic disorders in horses. BioVenic offers animal feed analysis services to help equine nutrition researchers formulate appropriate modeling diets. Our services cover analyzing equine diet nutrient composition, digestibility, anti-nutritional factor, and more.
- Evaluation of Biomarkers in Equine Metabolic Disorder Models
Biomarkers play a crucial role in equine nutritional research as they indicate the occurrence, severity, and efficacy of therapeutic measures for metabolic disorders. Through our animal nutrition and metabolism analysis service, researchers can qualitatively and quantitatively determine equine nutritional and metabolic markers using advanced immunological and biochemical analytical instruments. Our omics platform enables high-throughput analysis of metabolomics, proteomes, and microbiomes to cater to diverse research needs.
Common Metabolic Disorders in Horses
| Metabolic Disorders | Causes | Indicators |
|---|---|---|
| Equine metabolic syndrome (EMS) |
|
|
| Equine Cushing's disease (ECD) or pituitary pars intermedia dysfunction (PPID) | The normal mechanisms that control hormone production by the pituitary gland are damaged. |
|
| Recurrent Equine Rhabdomyolysis (RER) | An inherited trait caused by abnormal intracellular calcium regulation during muscle contraction. |
|
| Polysaccharide Storage Myopathy (PSSM) |
|
|
| Osteochondrosis (OCD) | Diet, growth rate, certain hereditary factors and trauma in orthopaedic disorders. |

Related Research
In a study characterizing metabolic and adipokine profiles in equine metabolic syndrome, adiposity was evaluated using body condition score (BCS) and cresty neck score (CNS) in a cohort of horses, with plasma levels of total cholesterol, insulin, non-esterified fatty acids (NEFA), omentin, and chemerin measured by ELISA. Spearman correlation and hierarchical clustering analysis revealed significant positive correlations between NEFA and bodyweight (r = 0.322; p = 0.006), BCS (r = 0.295; p = 0.013), and CNS (r = 0.267; p = 0.024). Total cholesterol correlated positively with bodyweight (r = 0.262; p = 0.027), and omentin correlated with CNS (r = 0.234; p = 0.049). Cluster analysis identified four distinct metabolic phenotypic groups, supporting the use of NEFA, chemerin, and omentin as complementary biomarkers for characterizing equine metabolic syndrome severity. This study establishes a multi-biomarker clustering approach for phenotyping equine metabolic disorder models, enabling more precise classification of metabolic risk beyond traditional insulin and glucose measurements

Applications of Equine Metabolic Disorder Models
- Evaluation of Equine Nutritional Strategies
Dietary management is often employed to control equine metabolic disorders. For example, restricting dietary carbohydrates is crucial in reducing glycemic and insulinemic responses in treating EMS. By assessing the effects of nutritional strategies on animals with metabolic disorders, equine nutritionists can validate the efficacy of diets and design novel nutritional approaches for horses with such disorders.
- Exploration of Mechanisms in Equine Metabolic Disorders
Studying the biological mechanisms underlying metabolic disorder models in horses helps deepen our understanding of equine physiology, including the role of diet, exercise, genetics, and other contributing factors. This knowledge contributes significantly to comprehending the intricate interplay within equine metabolic disorders.
- Treatment Development for Equine Metabolic Disorders
Metabolic disorders in horses are complex, and traditional methods such as diet and exercise may not always suffice. Equine metabolic disorder models allow for exploring the feasibility of novel treatments, such as cell-based targeted treatments, providing potential breakthroughs in the treatment of equine metabolic disorders.

Case Study: Validation of an Equine Metabolic Syndrome (EMS) Model
Objective: A client needed independent confirmation that their equine metabolic syndrome (EMS) model had been successfully established before evaluating a feed additive. BioVenic provided a model-validation service: the client shipped matched serum samples from model and healthy-control horses, and BioVenic ran a standardized ELISA + biochemical panel to verify the disease phenotype.
Animals: Horses assigned to a Model group and a Healthy Control group (balanced diet).
Samples provided by client: Fasting serum collected at study endpoint.
BioVenic validation panel: Serum insulin, glucose, leptin, adiponectin, and triglycerides by ELISA/microplate biochemistry; ACTH as a supportive endocrine readout.

Frequently Asked Questions
Q1: What analytical platforms characterize equine metabolic biomarkers?
A: We combine advanced immunological and biochemical analyzers—for insulin, ACTH, CK, AST, leptin, and lipid fractions—with our omics platform for high-throughput metabolomics (LC-MS/MS, GC-MS), proteomics, and microbiome analysis. This integrated readout captures both classic endocrine/biochemical markers and pathway-level signatures to give you robust, multi-layer validation of the model.
Q2: How can equine models support nutritional-strategy and therapy development?
A: Equine metabolic disorder models are ideal for validating nutritional management—such as dietary carbohydrate restriction to lower glycemic and insulinemic responses in EMS—and for designing novel feeds. Beyond diet, they let you probe mechanisms linking diet, exercise, and genetics, and explore newer treatment avenues like cell-based targeted therapies for complex disorders.
