A purebred horse is usually worth more than a horse of mixed breeding, though this matters more in some disciplines than others. The breed of the horse is sometimes secondary when breeding for a sport horse , but some disciplines may prefer a certain breed or a specific phenotype of horse.
The evolution of the horse, a mammal of the family Equidae, occurred over a geologic time scale of 50 million years, transforming the small, dog-sized, [1] forest-dwelling Eohippus into the modern horse. Paleozoologists have been able to piece together a more complete outline of the evolutionary lineage of the
A graminivore is a herbivorous animal that feeds primarily on grass, [1] specifically "true" grasses, plants of the family Poaceae (also known as Graminae). Graminivory is a form of grazing . These herbivorous animals have digestive systems that are adapted to digest large amounts of cellulose , which is abundant in fibrous plant matter and ...
A wide range of other species, such as horse, water buffalo, llama, rabbit, and guinea pig, are used as livestock in some parts of the world. Insect farming, as well as aquaculture of fish, molluscs, and crustaceans, is widespread. Modern animal husbandry relies on production systems adapted to the type of land available.
Related to this need to flee from predators in the wild is an unusual trait: horses are able to sleep both standing up and lying down, with younger horses tending to sleep significantly more than adults. [4] Female horses, called mares, carry their young for approximately 11 months and a young horse, called a foal, can stand and run shortly ...
A few types of organisms, such as many fungi and the ciliate Paramecium aurelia, [11] have more than two "sexes", called mating types. Most animals (including humans) and plants reproduce sexually. Sexually reproducing organisms have different sets of genes for every trait (called alleles). Offspring inherit one allele for each trait from each ...
Mules need less protein than horses and do best on grass hay with a vitamin and mineral supplement. [58] If mules are fed concentrates, they only need about half of what a horse requires. [59] Like horses, mules require fresh, clean water, but are less likely to over-drink when hot. [58] Donkeys, like mules, need less protein and more fiber ...
Red kangaroo grazing. Grazing is a method of feeding in which a herbivore feeds on low-growing plants such as grasses or other multicellular organisms, such as algae.Many species of animals can be said to be grazers, from large animals such as hippopotamuses to small aquatic snails.
