Belgian Blue Cattle
The Belgian Blue (, , both literally meaning "Belgian White-Blue") is a breed of beef cattle from Belgium. It may also be known as the , or (literally "fat buttocks" in Dutch). Alternative names for this breed include Belgian Blue-White; Belgian White and Blue Pied; Belgian White Blue; Blue; and Blue Belgian. The Belgian Blue's extremely lean, hyper-sculpted, ultra-muscular physique is termed " double-muscling". The double-muscling phenotype is a heritable condition caused by a deletion in the myostatin gene, resulting in an increased number of muscle fibres (hyperplasia), instead of the (normal) enlargement of ''individual'' muscle fibres (hypertrophy). This particular trait is shared with another breed of cattle known as Piedmontese. Both of these breeds have an increased ability to convert feed into lean muscle, which causes these particular breeds' meat to have a reduced fat content and reduced tenderness. The Belgian Blue is named after its typically blue-grey mottle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DAD-IS
DAD-IS is the acronym for the Domestic Animal Diversity Information System, a tool developed and maintained by the Food and Agriculture Organization of the United Nations as a part of its programme for management of animal genetic resources for food and agriculture. It includes a searchable database of information on animal breeds. Overview The FAO began to collect data on animal breeds in 1982. The first version of DAD-IS was launched in 1996 and the software has been updated several times; the fourth version was launched in 2017. DAD-IS includes a searchable database of information about animal breeds, the Global Databank for Animal Genetic Resources. It contains information on breed characteristics, uses, geographic distribution and demographics; more than images; and tools for generating user-defined reports; and has a multilingual interface and content. It also provides contact information for the national and regional coordinators for the programme. Data is collected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shorthorn Cattle
The Shorthorn breed of cattle originated in the North East of England in the late eighteenth century. The breed was developed as dual-purpose, suitable for both dairy and beef production; however, certain blood lines within the breed always emphasised one quality or the other. Over time, these different lines diverged, and by the second half of the twentieth century, two separate breeds had developed – the Beef Shorthorn, and the Milking Shorthorn. All Shorthorn cattle are coloured red, white, or roan, although roan cattle are preferred by some, and completely white animals are not common. However, one type of Shorthorn has been bred to be consistently white – the Whitebred Shorthorn, which was developed to cross with black Galloway cattle to produce a popular blue roan crossbreed, the Blue Grey. History The breed developed from Teeswater and Durham cattle found originally in the North East of England. In the late eighteenth century, the Colling brothers, Charles and R ...

Caesarean Section
Caesarean section, also known as C-section, cesarean, or caesarean delivery, is the Surgery, surgical procedure by which one or more babies are Childbirth, delivered through an incision in the mother's abdomen. It is often performed because vaginal delivery would put the mother or child at risk (of paralysis or even death). Reasons for the operation include, but are not limited to, obstructed labor, twin pregnancy, pre-eclampsia, high blood pressure in the mother, breech birth, shoulder presentation, 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 previous C-section, vaginal birth after C-section may be possible. The World Health Organization recommends that caesarean section be performed only when medically necessary. A C-section typically takes 45 minutes to an hour. It may be done with a spinal block, where the woman is awake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dystocia
Obstructed labour, also known as labour dystocia, is the baby not exiting the pelvis because it is physically blocked 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 ma ...

Feed Conversion Ratio
In animal husbandry, feed conversion ratio (FCR) or feed conversion rate is a ratio or rate measuring of the efficiency with which the bodies of livestock convert animal feed into the desired output. For dairy cows, for example, the output is milk, whereas in animals raised for meat (such as beef cows,Dan Shike, University of IllinoiBeef Cattle Feed Efficiency/ref> pigs, chickens, and fish) the output is the flesh, that is, the body mass gained by the animal, represented either in the final mass of the animal or the mass of the dressed output. FCR is the mass of the input divided by the output (thus mass of feed per mass of milk or meat). In some sectors, feed efficiency, which is the output divided by the input (i.e. the inverse of FCR), is used. These concepts are also closely related to efficiency of conversion of ingested foods (ECI). Background Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of outpu ...

Mutation
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication ( translesion synthesis). Mutations may also result from substitution, insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce detectable changes in the observable characteristics ( phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Mutati ...

West Texas
West Texas is a loosely defined region in the U.S. state of Texas, generally encompassing the desert climate, arid and semiarid climate, semiarid lands west of a line drawn between the cities of Wichita Falls, Texas, Wichita Falls, Abilene, Texas, Abilene, and Del Rio, Texas, Del Rio. No consensus exists on the boundary between East Texas and West Texas. While most Texans understand these terms, no boundaries are officially recognized and any two people are likely to describe the boundaries of these regions differently. The historian and geographer Walter Prescott Webb has suggested that the 98th meridian west, 98th meridian separates East and West Texas; writer A.C. Greene proposed that West Texas extends west of the Brazos River. Use of a single line, though, seems to preclude the use of other separators, such as an area—Central Texas. Texas is part of the Southern United States, South and the American Southwest at the same time, while the semiarid and desert climates of Wes ...

Linebreeding
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious recessive traits resulting from incestuous sexual relationships and consanguinity. Animals avoid inbreeding only rarely. Inbreeding results in homozygosity which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce. An individual who inherits such deleterious traits is colloquially referred to as ''inbred''. The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for out ...

Liège Province
Liège ( ; ; ; ; ) is the easternmost province of the Wallonia region of Belgium. Liège Province is the only Belgian province that has borders with three countries. It borders (clockwise from the north) the Dutch province of Limburg, the German states of North Rhine-Westphalia and Rhineland-Palatinate, the Luxembourgish canton of Clervaux, the Belgian Walloon (French-speaking) provinces of Luxembourg, Namur and Walloon Brabant and the Belgian Flemish (Dutch-speaking) provinces of Flemish Brabant and Limburg. Part of the eastern-most area of the province, bordering Germany, is the German-speaking region of Eupen-Malmedy, which became part of Belgium in the aftermath of World War I. The capital and the largest city of the province is the city of the same name, Liège. The province has an area of , and a population of 1.12 million as of January 2024. History The modern borders of the province of Liège date from 1795, which saw the unification of the Principali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 a 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). Where gametes from a third party are used, the procedure may be known as 'assisted insemination'. 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 hi ...

Dairy Cattle
Dairy cattle (also called dairy cows) are cattle bred with the ability to produce large quantities of milk, from which dairy products are made. Dairy cattle generally are of the species '' Bos taurus''. Historically, little distinction was made between dairy cattle and beef cattle, with the same stock often being used for both meat and milk production. Today, the bovine industry is more specialized and most dairy cattle have been bred to produce large volumes of milk. Management Dairy cows may be found either in herds or dairy farms, where dairy farmers own, manage, care for, and collect milk from them, or on commercial farms. Herd sizes vary around the world depending on landholding culture and social structure. The United States has an estimated 9 million cows in around 75,000 dairy herds, with an average herd size of 120 cows. The number of small herds is falling rapidly, with 51% of U.S. milk in 2007 produced by the 3,100 herds with over 500 cows. The United Kingdo ...

Charolais Cattle
The Charolais () or Charolaise () is a French breed of taurine beef cattle. It originates in, and is named for, the Charolais area surrounding Charolles, in the Saône-et-Loire department, in the Bourgogne-Franche-Comté region of eastern France. Charolais are raised for meat, which is relatively lower in fat. The breed is also selected for hardiness and docility. They may be crossed with other breeds for desired characteristics. Common crossbreeds include Angus and Hereford cattle. History The Charolais is the second-most numerous cattle breed in France after the Holstein Friesian and is the most common beef breed in that country, ahead of the Limousin. At the end of 2014, France had 4.22 million head of Charolais, including 1.56 million cows, down 0.6% from a year earlier. The Charolais is a world breed: it is reported to DAD-IS by 68 countries, of which 37 report population data. The world population is estimated at 730,000. The largest populations are reported from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
