Horse breeding. Horse breeding is reproduction in horses, and particularly the human-directed process of selective breeding of animals, particularly purebred horses of a given breed. Planned matings can be used to produce specifically desired characteristics in domesticated horses. Furthermore, modern breeding management and technologies can ...
The horse is considered a "thin animal" (with little fat), whose weight is divided into approximately 11 % bone, 50 % muscle and 9 % fat; [2] but a large number of factors influence its weight. Some breeds (draft horses) are naturally heavier than others , and differ in size and bone structure, so the weight range of horses is highly variable.
List of mammalian gestation durations. This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically ...
A female dog is usually diestrous (goes into heat typically twice per year), although some breeds typically have one or three cycles per year. The proestrus is relatively long at 5 to 9 days, while the estrus may last 4 to 13 days, with a diestrus of 60 days followed by about 90 to 150 days of anestrus.
Sometimes, weight loss is a symptom of a more serious medical condition. Any horse with an unexplained weight loss usually should be examined by a veterinarian. [4] [5] A normal horse may become a hard keeper when it becomes older, particularly when over the age of 20 to 25 years.
at least 48 published. The horse (Equus ferus caballus) [ 2 ][ 3 ] is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of Equus ferus. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into the large, single-toed animal of ...
The Henneke horse body condition scoring system is a numerical scale used to evaluate the amount of fat on a horse's body. It was developed in the early 1980s by Don Henneke at Texas A&M University with the goal of creating a universal scale to assess horses' bodyweight, [1] and was first published in 1983. [2]
Gestation. Drawing of a fetus in utero. Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). [1] It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for ...
