Dutch Improved Red Pied
The Dutch Improved Red Pied, nl, Verbeterd Roodbont, italic=no, is a recentlydeveloped Dutch breed of beef cattle. It derives from the dual-purpose Meuse-Rhine-Issel breed, and is characterised by a high incidence of the double-muscling gene. A breed association was started in 1988. History The Dutch Improved Red Pied derives from the Meuse-Rhine-Issel, a dual-purpose breed reared both for milk and for beef. The muscular hyperplasia known as double muscling was first observed in that breed in 1937, but because of the associated dystocia was regarded as undesirable or as a defect. With the greater availability of antibiotics in the years after the Second World War, it became possible to deliver calves by Caesarian section, and from the 1960s semen from double-muscled Meuse-Rhine-Issel bulls became available for artificial insemination. Selection of these animals for beef production alone led to the creation of the Verbeterd Roodbont, for which a breed association was started in ...

Beef Cattle
Beef cattle are cattle raised for meat production (as distinguished from dairy cattle, used for milk production). The meat of mature or almost mature cattle is mostly known as beef. In beef production there are three main stages: cow-calf operations, backgrounding, and feedlot operations. The production cycle of the animals starts at cow-calf operations; this operation is designed specifically to breed cows for their offspring. From here the calves are backgrounded for a feedlot. Animals grown specifically for the feedlot are known as feeder cattle, the goal of these animals is fattening. Animals not grown for a feedlot are typically female and are commonly known as replacement heifers. While the principal use of beef cattle is meat production, other uses include leather, and beef by-products used in candy, shampoo, cosmetics, and insulin. Calving and breeding Besides breeding to meet the demand for beef production, owners also use selective breeding to attain specific trai ...

Meuse-Rhine-Issel
The Meuse-Rhine-Issel or Meuse-Rhine-Yssel ( nl, Maas-Rijn-IJssel, italic=no) is a Dutch breed of dual-purpose cattle, reared both for meat and for milk. It falls within the Lowland-Pied group of North European cattle; it is red-pied, and of medium-large size. History The Meuse-Rhine-Issel developed principally in two areas of Holland: the eastern part of the province of Noord-Brabant in the southern part of the country, where the rivers Meuse and Rhine flow; and the area of the river IJssel in the east, mainly in Salland and Twente in the province of Overijssel, but extending southwards into the Achterhoek of Gelderland and northwards into the province of Drenthe. It is named for the three rivers. It was registered in the herd-book of the from 1874; it was recognised as a breed in 1905, and a separate herd-book was started. Numbers are in steep decline: in the 1970s there were more than half a million of the cattle, representing approximately a quarter of the total num ...

Double Muscling In Cattle
Myostatin (also known as growth differentiation factor 8, abbreviated GDF8) is a protein that in humans is encoded by the ''MSTN'' gene. Myostatin is a myokine that is produced and released by myocytes and acts on muscle cells to inhibit muscle growth. Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family. Myostatin is assembled and produced in skeletal muscle before it is released into the blood stream. Most of the data regarding the effects of myostatin comes from studies performed on mice. Animals either lacking myostatin or treated with substances that block the activity of myostatin have significantly more muscle mass. Furthermore, individuals who have mutations in both copies of the myostatin gene have significantly more muscle mass and are stronger than normal. There is hope that studies into myostatin may have therapeutic application in treating muscle wasting diseases such as muscular dystrophy. Discovery and seque ...

Breed Association
Breed clubs are associations or clubs with activities centered on a single, specific breed of a particular species of domesticated animal. The purpose of the association will vary with the species of animal and the goals and needs of the members of the association. Breed associations or clubs may vary in their goals, activities and nomenclature from country to country, even for the same breed. Most domesticated animals, whether they are agricultural animals such as cattle, llamas, poultry, sheep and pigs, or companion animals such as pigeons, horses, cats and dogs, have breed clubs associated with the breed. Purpose In general, breed clubs and associations create a written definition of the breed (called a breed standard) for the breed with which the organization is associated. Breed clubs also maintain important records, and provide members with information. Many breed associations also have a social component, organising various activities such as shows. In addition, they may r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperplasia
Hyperplasia (from ancient Greek ὑπέρ ''huper'' 'over' + πλάσις ''plasis'' 'formation'), or hypergenesis, is an enlargement of an organ or tissue caused by an increase in the amount of organic tissue that results from cell proliferation. It may lead to the gross enlargement of an organ, and the term is sometimes confused with benign neoplasia or benign tumor. Hyperplasia is a common preneoplastic response to stimulus. Microscopically, cells resemble normal cells but are increased in numbers. Sometimes cells may also be increased in size (hypertrophy). Hyperplasia is different from hypertrophy in that the adaptive cell change in hypertrophy is an increase in the ''size'' of cells, whereas hyperplasia involves an increase in the ''number'' of cells. Causes Hyperplasia may be due to any number of causes, including proliferation of basal layer of epidermis to compensate skin loss, chronic inflammatory response, hormonal dysfunctions, or compensation for damage o ...

Dystocia
Obstructed labour, also known as labour dystocia, is the baby not exiting the pelvis because it is physically block during childbirth although the uterus contracts normally. Complications for the baby include not getting enough oxygen which may result in death. It increases the risk of the mother getting an infection, having uterine rupture, or having post-partum bleeding. Long-term complications for the mother include obstetrical fistula. Obstructed labour is said to result in prolonged labour, when the active phase of labour is longer than 12 hours. The main causes of obstructed labour include a large or abnormally positioned baby, a small pelvis, and problems with the birth canal. Abnormal positioning includes shoulder dystocia where the anterior shoulder does not pass easily below the pubic bone. Risk factors for a small pelvis include malnutrition and a lack of exposure to sunlight causing vitamin D deficiency. It is also more common in adolescence as the pelvis may not ha ...

Antibiotics
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity. Antibiotics are not effective against viruses such as the common cold or influenza; drugs which inhibit viruses are termed antiviral drugs or antivirals rather than antibiotics. Sometimes, the term ''antibiotic''—literally "opposing life", from the Greek roots ἀντι ''anti'', "against" and βίος ''bios'', "life"—is broadly used to refer to any substance used against microbes, but in the usual medical usage, antibiotics (such as penicillin) are those produced naturally (by one microorganism fighting another), whereas non-antibiotic antibacterials (such as sulfonamides and antisep ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caesarian Section
Caesarean section, also known as C-section or caesarean delivery, is the surgical procedure by which one or more babies are delivered through an incision in the mother's abdomen, often performed because vaginal delivery would put the baby or mother at risk. Reasons for the operation include obstructed labor, twin pregnancy, high blood pressure in the mother, breech birth, and problems with the placenta or umbilical cord. A caesarean delivery may be performed based upon the shape of the mother's pelvis or history of a previous C-section. A trial of vaginal birth after C-section may be possible. The World Health Organization recommends that caesarean section be performed only when medically necessary. Most C-sections are performed without a medical reason, upon request by someone, usually the mother. A C-section typically takes 45 minutes to an hour. It may be done with a spinal block, where the woman is awake, or under general anesthesia. A urinary catheter is used to drain t ...

Semen
Semen, also known as seminal fluid, is an organic bodily fluid created to contain spermatozoa. It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals and can fertilize the female ovum. Semen is produced and originates from the seminal vesicle, which is located in the pelvis. The process that results in the discharge of semen from the urethral orifice is called ejaculation. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or "swim". The fluid is designed to be discharged deep into the vagina, so the spermatozoa can pass into the uterus and form a zygote with an egg. Semen is also a form of genetic material. In animals, semen has been collected for cryoconservation. Cryoconservation of animal genetic resources is a practice that call ...

Artificial Insemination
Artificial insemination is the deliberate introduction of sperm into a female's cervix or uterine cavity for the purpose of achieving a pregnancy through in vivo fertilization by means other than sexual intercourse. It is a fertility treatment for humans, and is common practice in animal breeding, including dairy cattle (see Frozen bovine semen) and pigs. Artificial insemination may employ assisted reproductive technology, sperm donation and animal husbandry techniques. Artificial insemination techniques available include intracervical insemination (ICI) and intrauterine insemination (IUI). Humans History The first recorded case of artificial insemination was John Hunter in 1790, who helped impregnate a linen draper's wife. The first reported case of artificial insemination by donor occurred in 1884: William H. Pancoast, a professor in Philadelphia, took sperm from his "best looking" student to inseminate an anesthetized woman without her knowledge. The case was reporte ...
