Cow-hocked
Cow-hocked ( adj.) or cow hocks ( n.) describes a defect in the conformation of four-legged animals, primarily of livestock and horses, but also of dogs and cats. Description An animal is cow-hocked when its hock is set inward, resulting in a splayed look in the back legs. This can result in the uneven wearing of hooves, which can end up in permanent lameness, and can prove to be a very serious condition. Permanent lameness usually results in the animal going for meat, as the cow will be in far too much pain to move, the milk in a cow will not be up to standard, and the animal could not be used in breeding, as this trait would pass on. However, most animals will not have too serious a condition, and will walk with a splayed-leg look. Another way of spotting cow-hock is when the hooves point outward as a result of the incorrect lineup of the joints in the leg. Another problem with cow-hocks is when the joints in the leg are not set correctly, the joints in the back will most li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hock (anatomy)
The hock, or gambrel, is the joint between the tarsal bones and tibia of a digitigrade or unguligrade quadrupedal mammal, such as a horse, cat, or dog. This joint may include articulations between tarsal bones and the fibula in some species (such as cats), while in others the fibula has been greatly reduced and is only found as a vestigial remnant fused to the distal portion of the tibia (as in horses).{{citation needed, date=January 2016 It is the anatomical homologue of the ankle of the human foot. While homologous joints occur in other tetrapods, the term is generally restricted to mammals, particularly long-legged domesticated species. Horse Although the ''tarsus'' refers specifically to the bones and joints of the hock, most people working with horses refer to the ''hock'' in such a way to include the bones, joints, and soft tissue of the area. The hock is especially important in equine anatomy, due to the great strain it receives when the horse is worked. Jumping, and mov ...

Equine Conformation
Equine conformation evaluates a horse's bone structure, musculature, and its body proportions in relation to each other. Undesirable conformation can limit the ability to perform a specific task. Although there are several faults with universal disadvantages, a horse's conformation is usually judged by what its intended use may be. Thus "form to function" is one of the first set of traits considered in judging conformation. A horse with poor form for a Grand Prix show jumper could have excellent conformation for a World Champion cutting horse, or to be a champion draft horse. Every horse has good and bad points of its conformation and many horses (including Olympic caliber horses) excel even with conformation faults. Conformation of the head and neck The standard of the ideal head varies dramatically from breed to breed based on a mixture of the role the horse is bred for and what breeders, owners and enthusiasts find appealing. Breed standards frequently cite large eyes, a br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

9 (nine) is the natural number following and preceding . Evolution of the Arabic digit In the beginning, various Indians wrote a digit 9 similar in shape to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a -look-alike. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic. While the shape of the glyph for the digit 9 has an ascender in most modern typefaces, in typefaces with text figures the character usually has a descender, as, for example, in . The mod ...

Phenotypic Trait
A phenotypic trait, simply trait, or character state is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two.Lawrence, Eleanor (2005) ''Henderson's Dictionary of Biology''. Pearson, Prentice Hall. For example, having eye color is a ''character'' of an organism, while blue, brown and hazel versions of eye colour are ''traits''. The term ''trait'' is generally used in genetics, often to describe phenotypic expression of different combinations of alleles in different individual organisms within a single population, such as the famous purple vs. white flower coloration in Gregor Mendel's pea plants. By contrast, in systematics, the term is ''character state'' is employed to describe features that represent fixed diagnostic differences among taxa, such as the absence of tails in great apes, relative to other primate groups.

Horse Anatomy
Equine anatomy encompasses the gross and microscopic anatomy of horses, ponies and other equids, including donkeys, mules and zebras. While all anatomical features of equids are described in the same terms as for other animals by the International Committee on Veterinary Gross Anatomical Nomenclature in the book ''Nomina Anatomica Veterinaria'', there are many horse-specific colloquial terms used by equestrians. External anatomy * Back: the area where the saddle sits, beginning at the end of the withers, extending to the last thoracic vertebrae (colloquially includes the loin or "coupling," though technically incorrect usage) * Barrel: the body of the horse, enclosing the rib cage and the major internal organs * Buttock: the part of the hindquarters behind the thighs and below the root of the tail * Cannon or cannon bone: the area between the knee or hock and the fetlock joint, sometimes called the "shin" of the horse, though technically it is the third metacarpal * Chestnut: ...

Livestock
Livestock are the domesticated animals raised in an agricultural setting to provide labor and produce diversified products for consumption such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals who are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, goats and pigs. Horses are considered livestock in the United States. The USDA classifies pork, veal, beef, and lamb (mutton) as livestock, and all livestock as red meat. Poultry and fish are not included in the category. The breeding, maintenance, slaughter and general subjugation of livestock, called '' animal husbandry'', is a part of modern agriculture and has been practiced in many cultures since humanity's transition to farming from hunter-gatherer lifestyles. Animal husbandry practices have varied widely across cultures and time periods. It continues to play a major economic and cultural role in numerous communities. Lives ...

Post-legged
Post-legged describes a condition in which the joints in an animal are not set correctly. When an animal is post-legged, the leg joints are far too straight, with almost no bend in the legs. Four-legged animals must have some bend in the hocks, otherwise the hooves would wear unevenly, and this may result in lameness, or at least a rougher gait. The animal will not stand squarely on the ground, and this also increases the possibility of injury to the animal. When an animal is post-legged, the animal will have a much higher risk of lameness, perhaps even permanent. This means the animal can hardly move at all, and results in an extremely stressed animal. This may also result in the animal not being able to move to food, and could be life-threatening. Also, since the animal is in such pain, it may be so stressed that it won't calve well, and it will not produce good quality milk, -or any milk at all- in a cow. Animals with a problem in their leg joints are recommended to be remove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow-legged
Genu varum (also called bow-leggedness, bandiness, bandy-leg, and tibia vara) is a varus deformity marked by (outward) bowing at the knee, which means that the lower leg is angled inward ( medially) in relation to the thigh's axis, giving the limb overall the appearance of an archer's bow. Usually medial angulation of both lower limb bones (femur and tibia) is involved. Causes If a child is sickly, either with rickets or any other ailment that prevents ossification of the bones or is improperly fed, the bowed condition may persist. Thus the chief cause of this deformity is rickets. Skeletal problems, infection, and tumors can also affect the growth of the leg, sometimes giving rise to a one-sided bow-leggedness. The remaining causes are occupational, especially among jockeys, and from physical trauma, the condition being very likely to supervene after accidents involving the condyles of the femur. Childhood Children until the age of 3 to 4 have a degree of genu varum. The c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sickle-hocked
A sickle-hocked leg structure is one in which the back leg joints of an animal, usually a horse or other equine mammal, are set with too much angle, resulting in the hock also being excessively angled. This can result in uneven hoof wear, which is incredibly painful for the affected horse. If the leg joints are not set properly, there is a high chance that the back joints are also set incorrectly, resulting in a poorly conformed horse. Horses with sickle-hocks are at an increased risk of developing thoroughpin, curb and bog or bone spavins. Very severe cases of sickle-hocks can result in permanent lameness and may require euthanization to prevent further pain. However, many horses with sickle-hock are not affected to this degree, and may live a life with uneven wearing hooves. Corrective shoeing can help the horse's balance and strength. Horses with sickle-hocks should be monitored closely for signs of lameness, and if possible a veterinarian should be consulted before extensive ...

Metatarsal
The metatarsal bones, or metatarsus, are a group of five long bones in the foot, located between the tarsal bones of the hind- and mid-foot and the phalanges of the toes. Lacking individual names, the metatarsal bones are numbered from the medial side (the side of the great toe): the first, second, third, fourth, and fifth metatarsal (often depicted with Roman numerals). The metatarsals are analogous to the metacarpal bones of the hand. The lengths of the metatarsal bones in humans are, in descending order, second, third, fourth, fifth, and first. Structure The five metatarsals are dorsal convex long bones consisting of a shaft or body, a base (proximally), and a head (distally).Platzer 2004, p. 220 The body is prismoid in form, tapers gradually from the tarsal to the phalangeal extremity, and is curved longitudinally, so as to be concave below, slightly convex above. The base or posterior extremity is wedge-shaped, articulating proximally with the tarsal bones, and by it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural
Agriculture or farming is the practice of cultivating Plant, plants and livestock. Agriculture was the key development in the rise of Sedentism, sedentary human civilization, whereby farming of Domestication, domesticated species created food Economic surplus, surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into Food, foods, Fiber, fibers, fuels, and raw materials (such as Natural rubber, rubber). Food clas ...
