Warm-Blood: Definition and Major Warmblood Horse Breeds
Warm-blooded (or warmblood) is a classification for horse breeds that were developed by systematically crossing heavy cold-blooded draft breeds with lighter hot-blooded Arabian and Thoroughbred stock, with the goal of producing athletic horses with the power and substance of the draft and the refinement, movement, and trainability of the hot-blood. The result is the modern…

Tumor
A tumor is an abnormal mass of tissue that arises when cells multiply without the normal regulatory constraints governing growth and death. Tumors are classified as benign (locally contained, non-invasive, and generally not life-threatening) or malignant (invasive, capable of spreading to distant sites via the lymphatic or vascular systems , a process called metastasis). In…

Toxemia
Toxemia is a condition in which toxins , produced by bacteria, released from dying tissue, or generated by abnormal metabolic processes , circulate in the bloodstream at levels sufficient to cause systemic pathology. In horses, toxemia most commonly arises as a complication of severe gastrointestinal disease, infected wounds, or conditions involving extensive tissue necrosis. The…

Splint
A splint is a rigid or semi-rigid support applied externally to a limb to restrict movement, reduce pain, and protect damaged tissue while it heals. In equine medicine, splints are used after fractures of the lower leg, post-surgical stabilization, or when a soft-tissue injury requiring immobilization or ligament injury requires immobilization. Unlike a cast, a…

Septicemia
Septicemia is a condition in which bacteria or their toxins are circulating in the bloodstream and triggering a systemic inflammatory response. In horses, the term is applied most commonly to neonatal newborn foals, for whom it is one of the leading causes of early death. The neonatal foal is born with a naive immune system…

Cold-Blood: Definition of Cold-Blooded Horse Breeds
Cold-blooded is a classification applied to heavy draft horse breeds characterized by calm, placid temperaments, large body size (often 1,500 to 2,200 pounds or more), and selective breeding for pulling power and endurance at slow work rather than speed. Cold-blooded horses were developed in northern European climates for agricultural and transport work, where massive pulling…

Seizure
A seizure in a horse is an episode of abnormal, uncontrolled electrical activity in the brain that results in involuntary muscle contractions, loss of balance, altered consciousness, or collapse. The horse may paddle its legs, exhibit rhythmic jaw clenching, fall to the ground and thrash, or simply display sudden behavioral changes and ataxia depending on…

Malabsorption
Malabsorption is the impaired uptake of one or more nutrients from the intestinal lumen into the body’s systemic circulation despite adequate dietary intake, resulting in nutritional deficiency, weight loss, and secondary clinical signs that reflect the specific nutrients failing to be absorbed. In horses, malabsorption can affect simple sugars (glucose), proteins (amino acids), fats, fat-soluble…

Hot-Blood: Definition of Hot-Blooded Horse Breeds
Hot-blooded is a classification applied to horse breeds characterized by high energy levels, heightened sensitivity to stimuli, speed, and physical refinement. The term originates in the centuries-old practice of classifying horses by their breeding heritage and associated temperament. It refers to the horse's disposition and genetic heritage, not to its actual body temperature. Hot-blooded horses…

In Foal: Definition for Pregnant Mares
In foal is the standard equine term for a pregnant mare. The phrase appears in sales listings, breeding records, and veterinary documentation as confirmation that a mare is carrying a developing foal. A mare is confirmed in foal by a veterinary examination that may include rectal palpation, transrectal ultrasound (the most common modern method), or…
