Thoroughbred breeding theories, or racehorse theories, are used by horse breeders in an attempt to arrange matings that produce progeny successful in horse racing. Bloodstock experts also rely on these theories when purchasing young horses or breeding stock.
The Thoroughbred breed is an example of a closed stud book. Many warmblood breeds such as the Oldenburger have an open stud book with animals approved for registry via a studbook selection process. 2. A list of stallion s of a particular breed "standing at stud", that is, actively being bred. 3.
Horse behavior is best understood from the view that horses are prey animals with a well-developed fight-or-flight response. Their first reaction to a threat is often to flee, although sometimes they stand their ground and defend themselves or their offspring in cases where flight is untenable, such as when a foal would be threatened.
The Thoroughbred is a distinct breed of horse, although people sometimes refer to a purebred horse of any breed as a thoroughbred. The term for any horse or other animal derived from a single breed line is purebred.
Vacuum activities (or vacuum behaviours) are innate fixed action patterns (FAPs) of animal behaviour that are performed in the absence of a sign stimulus (releaser [broken anchor]) that normally elicit them. [1] This type of abnormal behaviour shows that a key stimulus is not always needed to produce an activity. [2]

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).
In Thoroughbred racing there are three main track surfaces: dirt, turf and synthetic. Dirt tracks are generally a mixture of sand, silt and clay. Japan Racing Association tracks use 7–8 cm of river sand cushion over a hard substrate, and New York Racing Association tracks use 10–12 cm of a sandy loam cushion over 25–27 cm of a clay / silt ...
To construct an optimality model, the behavior must first be clearly defined. Then, descriptions of how the costs and benefits vary with the way the behavior is performed must be obtained. [1] Examples of benefits and costs include direct fitness measures like offspring produced, change in lifespan, time spent or gained, or energy spent and gained.
