Glossary of Equine Terms

At the Horse Show

Attire: Rider's clothes

Barrel Racing: Standard gymkhana event. Cloverleaf pattern. The fastest time wins.

Calf Roping: A timed event where a rider catches a calf by throwing a loop of rope from a lariat around its neck, dismounts from the horse, runs to the calf, and restrains it by tying three legs together, in as short a time as possible.

Cross country: Includes events such as hunter trials that are timed and ridden at speed over natural fixed fences.

Cutting: A cutting horse and rider work as a team demonstrating the horse's athleticism and ability to handle cattle during a ​2 1⁄2 minute performance.

Dressage - A french word for training. Horse performs at increasing levels of performance in execution of various gaits and movements

Driving Pleasure: Based on how well the horse drives. They must have a nice gait, with the ideals of the breed in mind, to do well. A lame or naughty horse or pony will not do well in this class because it is not a "pleasure" for the person driving. Not judged on the handlers ability.

Driving Reinsmanship: Judged on how well the handler is at driving their horse. A pattern is usually involved as well as working on the rail.

Equitation: The art of riding horse back correctly; there are three main styles of equitation: hunter seat, saddle seat, and stock seat.

Items Related to Horse Vision

Behavior: The animal’s response to its environment.

Binocular Vision: Using both eyes to focus on things at the same time.

Cones: Cones are one of two types of photoreceptors (light-sensitive cells that turn images into electrical impulses to be sent to the brain via the optic nerve). Cones are necessary for sight in daylight and for distinguishing colors.

Conjunctiva: The conjunctiva is a mucous membrane that covers the eye and lines the underside of the eyelid.

Cornea: The cornea is the clear, outer surface of the eye. It is a clear, dome-shaped structure that protects the eye and lets in light. It assists in focusing light on the retina, which sits at the back of the eye. The sclera, the white of the eye, lay beneath the cornea, as do the iris and pupil.

Corpora Nigra: The corpora nigra is the irregular-looking area of the iris dipping into the pupil. It may look a little like an inconsistent wavy pattern. It can also be seen at the bottom of the pupil in some horses. This structure is thought to help with glare from the light to help horses see better.

Field of Vision: Horses see almost 360 degrees with the exception of right in front of them and behind them.

Iris: The iris is the colored part of the eye. The iris is usually a shade of brown in horses, ranging from a lighter amber color to a deep, dark brown. However, some horses have blue irises, or, extremely rarely, green!  The iris is also part of the uveal tract, which supplies the eye with blood. 

Lens: The lens of the eye sits just behind the iris and changes its shape in order to focus light onto the retina. The lens may become thicker or thinner, depending on whether the horse is focusing on something close (it becomes thicker) or far away (it becomes thinner).  The ciliary muscles are responsible for controlling the shape of the lens. 

Lower Eyelid: The lower eyelid is the structure of the skin at the bottom of the eye that helps spreads tears over the eye and keeps a protective moisture barrier and protects the eye from foreign objects. 

Monocular vision: Ability to see with each eye (monocular vision) independently so they may see what is happening on each side of their body.

Photo Receptor: cells in the retina that respond to light.

Predator: kills and eats other animals.

Prey: Animals that are eaten or hunted. A horse is a prey animal.

Pupil: The pupil is the black horizontal oval area within the iris that enlarges or shrinks, in order to let in more or less light. If it is low light or night out, the pupil will enlarge to let more light in and if it is bright, the pupil will shrink to limit the amount of light.

Retina: Contains the cells that sense light (photoreceptors).

Rods: Rods are one of two types of photoreceptors (light-sensitive cells that turn images into electrical impulses to be sent to the brain via the optic nerve). Rods are light-sensitive cells that allow sight in dimmer light.

Sclera: The sclera is the white of the eye.

Tapetum: The tapetum is reflective, located at the back of the eye, and helps improve vision in low light. This is the structure responsible for when we see “glowing” eyes from certain animals in the dark.

Third Eyelid/Nictating Membrane: The third eyelid, or nictating membrane, is a thin mucous membrane that is pulled across the eye when a horse blinks. It is located at the inner corner of the eye. The third eyelid may pull up if the eye is inflamed or injured.

Upper Eyelid: The upper eyelid is the structure of skin above the eye that helps spreads tears over the eye and keeps a protective moisture barrier and protects the eye from foreign objects. 

Vision: refers to the parts of the horse's eye and brain that enable the horse to see.

Visual Acuity: Visual acuity is the ability to see the details of an object separately and without blurring.

Nutrition - Feeds and Feeding

Ad libitum: Offering a horse as much feed as they want to eat.

Alfalfa: A flowering perennial plant that returns every year. When the plant is harvested and dried, it's often made into hay.

Amino Acids: Known as building blocks, they form chains to make up proteins. They can be split into essential and non-essential amino acids. Essential amino acids cannot be produced by the horse and must be provided by the diet An example is lysine.

As Fed: Nutrient results for a sample in its natural state including the water.

BalancerConcentrate feed providing vitamins, minerals and amino acids. They help to ensure that the horse has a balanced diet. They are often low in calories and energy.

Barley: Barley is about 11—13% protein and should be fed in a rolled or crushed form. It is relatively low in fiber and can cause digestive upsets if not mixed with sufficient roughage.

Beet pulp: Beet pulp is a byproduct from the processing of sugar beet which is used as fiber (hay substitute) for horses. It is supplied either as dried flakes or as compressed pellets. Beet pulp is low in sugar and other non-structural carbohydrates, but high in energy and fiber. Beet pulp has a relatively low protein content and good palatability.

Calcium: Calcium it is an essential mineral for bone and teeth formation, but also acts as an aid for muscle contraction, cell membrane function, enzyme regulation and blood clotting.

Cellulose: The main structure of the plant cell wall. Cellulose are not digested by mammalian enzymes in the small intestine, but are fermented by hind-gut microflora (bacteria).

Complete Feed: A feed designed to supply all the nutrients in the diet, including vitamins, minerals and adequate fiber levels to help maintain digestive health.

Concentrate: A feed used with another to improve the nutritive balance of the total and intended to be further diluted and mixed to produce a supplement or complete feed.

Corn: A tall cereal plant, cultivated in many varieties, having a jointed, solid stem and bearing the grain, seeds, or kernels on large ears.

Creep: An enclosure or feed used for supplemental feeding of nursing young that excludes their dams

Crimping: Grains are steamed and sent through a mechanical roller.

Cool-season grass: Grass types that thrive in areas with cold winters and hot summers. Examples include Kentucky bluegrass, Orchardgrass, Rye grass, Smooth brome grass, Timothy, Meadow Fescue and Tall fescue

Crude Fiber: Crude fiber is part of the labeling requirements for many horse  feeds. It is a reasonable estimate of fiber in grains and hay. Typically, when you look at the tag from a basic equine ration, the higher the crude fiber level listed, the lower the energy content of the feed.

Crude Protein: In horse feeds, protein is expressed as crude protein because it is an indirect or ‘crude’ estimation of that feed’s protein content. Proteins are organic compounds composed of amino acids. They are a major component of vital organs, tissue, muscle, hair, skin, milk and enzymes.

Digestible Energy (DE): The estimated energy content of the feed. It is measured in Mcal and provides a useful measure of the energy that the animal may be able to use from the feed.

Diet: Feed ingredients or mixture of ingredients including water, which is consumed by horses.

Easy keeper: An animal that grows or fattends rapidly on a limited amount of feed.

Electrolyte: Minerals that help maintain water balance and metabolism within the body. They are lost through sweat and urine, along with water. Sodium chloride (salt) is the most common; others include magnesium, potassium and calcium.

Energy Feeds: Feeds that are high in energy and low in fiber (less than 18%) and that generally contain less than 20% protein.

Essential Nutrients:  Those nutrients that cannot be made in the body from other substances or that cannot be made in sufficient quantity to supply the animal's needs; hence they must be supplied in the ration

Extruded: A process by which feed has been pressed, pushed, or protruded through orifices under pressure. The feed is subjected to increased pressure, friction, and attrition as it passes through a die opening. As the feed is released, it expands as steam is released because of the sudden drop in pressure.

Fat:  Fat is an energy dense nutrient and contains 2.25X the energy found in carbohydrates. Fat is added to rations to boost energy levels.

Feed or feedstuff: Edible material that is consumed by animals and contributes energy and/or nutrients to the animal's diet.

Flax: Flax is also known as linseed meal. Flax seed is the highest botanical form of omega-3 fatty acids and enhances overall health in horses. Flax seed meal should be ground as the outer seed coat is very hard and not digestible by the horse.

Forage: The vegetative portion of plants in a fresh, dried or ensiled state, which is fed to horses (as pasture or hay)

Fructan: Collective term used to describe carbohydrates containing multiple fructose units. Fructans are the main storage carbohydrate in cool season grasses. Fructans are not digested by mammalian enzymes in the small intestine, but are fermented by hind-gut microflora (bacteria)

Grass hay:  Grass hay is commonly made from timothy, fescue, bluegrass, orchard grass, Bermuda grass or brome grass.

Grain: Seed from cereal plants.

Hard keeper: An animal that is unthrifty and grows or fattens slowly regardless of the quantity or quality of feed.

Hay: The aerial portion of grass or herbage especially cut and cured for animal feeding.

Hay belly: Horse's belly distended as a result of excessive feeding of bulky rations, such as hay, straw or grass.

Hay quality: Physical and chemical characteristics of hay associated with palatability and abundance of feed nutrients

Legume:  A plant that has the ability to work symbiotically with bacteria to fix nitrogen from the air. Examples include alfalfa, red clover, white clover, and birdsfoot trefoil.

Lysine: An essential amino acid. The horse cannot produce it itself so it must be provided in the diet.

Macro Minerals:  The major minerals—those required in amounts of 100 milligrams or more per day—are calcium, phosphorus (phosphates), magnesium, sulfur, sodium, chloride, and potassium.

Maintenance Requirement: A ration that is adequate to prevent any loss or gain of tissue in the body when there is no production.

Non-Fiber Carbohydrates (NFC): An estimate of non-cell wall (non-fiber) carbohydrates consisting of starch, sugar, pectin and fermentation acids that can serve as energy sources for the animal.

Non-structural carbohydrates (NSC): Carbohydrates that occur either as simple sugars in the horse's feed or that can be broken down by enzymes produced by the horse. Included in this category are glucose and fructose, lactose, sucrose and starch.

Nutrient:  A feed constituent in a form and a level that will support the life of an animal.

Nutrient Requirements: Refers to meeting the animal's minimum needs, without margins of safety.

Omega Fatty Acids: Essential fatty acids that play an important role in the function and structure of cell membranes, prostaglandin synthesis, preventing dry, flaky skin and reducing inflammation.

Palability:  Factors sensed by the animal in locating and consuming feed; appearance, color, taste, texture and temperature of the feed

Pellets: Agglomerated feed formed by compacting and forcing through die openings by a mechanical process.

Pectin: A cell wall polysaccharide that functions as "cellular glue". It is also known as "soluble fiber".

Phosphorus: Mineral involved with bone and teeth formation and it is a key component of energy metabolism, milk component, body fluid buffer systems.

Protein– Essential building blocks for the body; it is used for growth and repair. Proteins are made up of amino acids.

Ration:  The amount of total feed that is provided to one animal over a 24-hour period.

Simple Sugars: Glucose, fructose and galactose are most often found as components of larger carbo­hydrate molecules.

Starch: A non-structural carbohydrate. It is broken down in the small intestine and delivers fast release energy. Cereals are high in starch.

Supper fibers - Super fiber is a product that contains highly digestible fiber with very little non-digestible fiber. These highly digestible fiber sources provide horses with a calorie content similar to grain, however since they are fiber they are safer to feed. Super Fibers are digested in the hindgut (cecum and colon) so they do not produce rapid changes in blood sugar like grain.

Supplement:  A feed used with another to improve nutritive balance or performance of the total.

Sweet feed: A commercial horse feed that is characterized by its sweetness because of the addition of molasses.

Trace Minerals (micro minerals): Mineral nutrients required by animals in micro amounts only - Cobalt, Copper, Iodine, Iron, Manganese, Selenium and Zinc

Vegetable Oil: Source of fat and energy for the horse. Liquid vegetable oil (corn and soybean oil), flax, and rice bran are several fat sources commonly utilized as energy sources for performance horses.

Vitamin A: Derived from carotene in green plants, it is important for normal eye and nerve function, maintenance of tissues in the reproductive and urinary tract, cell differentiation and required for normal growth, reproduction and lactation.

Vitamin D: Exposure to sunlight generates the synthesis of vitamin D in the skin. Vitamin D acts in conjunction with calcium and phosphorus to promote and maintain proper bone formation and integrity.

Vitamin E: Acts in conjunction with selenium as powerful antioxidants.

Warm Season Grass:  Forages thrive in hot, dry climates,  so they grow best during the summer.

Tack

Curb bit: A curb bit has a solid or broken mouthpiece, has shanks and acts with leverage. The bit works in conjunction with a curb chain, consisting of a straight mouthpiece attached at either end to long metal cheeks or shanks. All curb bits act on the nose, bars, lips, chin groove and tongue. Curbs with long shanks also act on the poll, and those with high ports act on the roof of the mouth. The action on the chin groove is via the curb chain, which acts as a fulcrum and without which the curb bit would only act as a snaffle.  A curb bit works by leverage on the lower jaw, applying pressure on the chin groove by means of the chain. The longer the lower section of the metal mouthpiece, the greater the pressure applied to the lower jaw.
