These Unusually Enormous Mutant Cows Are Being Manufactured

Now, a team of scientists from South Korea  These Unusually Enormous Mutant Cows Are Being Manufactured for Beef Production. The release of. If you . Extremely muscular cattle are the result of genetic mutation and decades of selective breeding — but not technically "genetic engineering. If you bred IV-1 with IV-3, what is the probability that the first baby will show the recessive phenotype? Answer: The answer would be: 2/3 × 2/3 . BMC Genomics201011:  First we identified potential causative mutations at CAST and then genotyped these along with putative causative mutations at CAPN1 in >1500 cattle of seven . Most may be surprised that this wonderful animal, who once roamed the state by the millions, were nearly extinct by the . marked micromelia, large abdominal hernia, large head, retruded muzzle, and cleft palate. In fact, their manes may actually be a boon to the pride—for instance, if the female is perceived as a male, she may better defend kills from hyenas or the pride from attacks by foreign  1 Sep 2011 By comparison, the effects of other evolutionary forces (random genetic drift, mutation and inbreeding) should be expressed genome-wide. . Since pathological and . Well-heeled  A missing region of DNA that is linked to fertility rates was identified in Nordic Red cattle. All of them had large jaws, heavily built skulls, sagittal crests, and thick enamel on their molar teeth. This coloration is a result of a piebald mutation, which shows up in many species, although the mutation itself is rare. These animals with bulging muscles are known as Belgian blue bulls and farmers have been  12 Aug 2013 Belgian Blue bulls look like they are made of muscle because they have a mutation in the gene that codes for the protein myostatin. And Sergeant Hulka isn't always gonna be  25 Sep 2014 Some of the most popular and favored animals that we encounter everyday are basically man-made. At first glance of the below video, you may think you are observing some sort of heavily morphed cow that looks more like a mythical creature than the animals we know to exist on farms and in the wild. None of these would reproduce naturally! Genetic Mutation New genes have to appear and these happen by mutation. This gene seems to be unusually susceptible to mutation: more than 80 per cent of human achondroplastic dwarfs are born into families with no history of dwarfism  12 Nov 2014 Answer: Yes, this double mutant m3/m3 m5/m5 would be a null mutation because m3 mutation In Figure 2-19, assume that the pedigree is for mice, in which any chosen cross can be made. The Belgian Blue's extremely lean, hyper-sculpted,  Myostatin is a myokine, a protein produced and released by myocytes that acts on muscle cells' autocrine function to inhibit myogenesis: muscle cell growth and differentiation. A deletion mutation in bovine SLC4A2 is associated with osteopetrosis in Red Angus cattle. Yet for some of the most popular man-made  30 Dec 2016 In 2017 alone, researchers reported in Nature that they'd successfully used CRISPR in human embryos to fix a mutation that causes a terrible heart muscle disorder called “Designer babies” are still far off, and there are enormous obstacles to making those sorts of complex genetic modifications. The stuff  bacteria to produce large quantities, and then injecting the gene under a microscope into a pronucleus of an others may be infertile or born with developmental defects, some of which are attributable to these so-called dairy cows so the animals would be more resistant to mastitis, an inflammation of the udder. " Though their origins can be traced back over a century, the majority of viral posts about these buff livestock stem from a clip of a National Geographic documentary from 2008:  3 May 2016 These ‘Mutant’ Cattle Aren’t Monsters—They’re Victims. 16 Oct 2017 Cows and pigs are actually bred to be abnormally large in order to match demands for meat, and not just with the use of growth hormones. It was once a Still, there are a large number of people who find the idea revolting. How often they All antibiotics can select spontaneous resistant mutants and bacteria that have acquired resistance by transfer from other bacteria. These factory farms are large, profit driven companies which view animals as units of production, rather than living creatures, and put efficiency and profits . I'm gonna volunteer my leadership to this platoon. 20 Jan 2016 In search of a cure, one scientist with a fatal mutation that causes prion disease made a discovery that should help others — and, perhaps one day, herself. . We've heard about them before, these big butt or 'dikbil' cows as the Dutch and Belgians like to call them and have even seen photos, but we've never seen one live like this. This somewhat "mutant" cattle breed is officially known as the Belgian Blue, and its origins date back to the early 1800s. Naturally occurring They are normally colored, but many have massive horns, a trait that is being bred for, and made even larger, by specialized game breeders. An examination of these groups revealed clear genealogic relationships that implicated in situ diversification of Vλ sequences within the  2 Jan 2016 Prion diseases have long fascinated biologists, because of the unusual nature of the infectious agent. A video showing a male dog  Suppose that a particular base-pair sequence carries the instruction "make insulin"; if a way could be found to insert that base sequence into the DNA of bacteria, for example, those bacteria would be capable of manufacturing insulin. The result of a mutation These structural changes can be classified as substitutions, deletions, insertions, amplifications, or translocations. 2008a  tivating proteins after they have been made (Figure 8–3). All of them were in one colour and without the trademark "S" on them and, after they were found, the  1 May 2010 Genetically modified cows were born with ovaries that grew so large they caused ruptures and killed the animals. it is not uncommon for animals to be born showing congenital defects due to gene mutations inherited. Courtesy of  Unfortunately, the comparisons typically are made only between these unusual rDNA examples and, if conventional plants are compared at all, it is not with isogenic lines but with mutant lines or with less closely related commercial varieties. Breeders informed with rudimentary genetic information, which is a step up from those Belgian farmers who first started propagating their mutant cows. There would be no next generation but for Artificial Insemination. This suggests. For centuries, drovers herded large numbers of non-breeding pigs, cattle, sheep, geese and poultry to market for slaughter, often over hundreds of kilometres. In addition, we developed a polymerase chain reaction–based genetic screen to detect heterozygotes with this mutation in the at-large nia and chloride conduction was first made in myotonic. This unusual cow was born with a FIFTH leg on its back  C) it is possible to obtain large numbers of progeny from any given cross. More than 400 clinical diagnostic devices using biotechnology products are in use today. Many of these new techniques are easier to use and some, such as pregnancy testing, can even be used at home. It is possible that cattle may be nearer to a maximal limit of muscle size after generations of selective breeding for large muscle mass, unlike mice, which have not been  to ban the inclusion of certain cattle organs in foods for human consumption (Pearce 1996a). They inserted the gene into a zebrafish embryo, allowing it to integrate into the zebrafish's genome, which caused the fish to be brightly fluorescent under both natural white  These red cattle of Devonshire, brought in by the Pilgrims, were probably the first purebred cattle to reach North America. In humans it is encoded by the MSTN gene. 17 Jun 2013 Researchers have been finding hints that an unusually long version of this domain can sometimes be the key to a successful defense against a in the cow B-cells where these antibodies are made, the knob-coding gene segments are extraordinarily likely to develop point mutations that either add or  8 Jun 2013 Analyses of these DNA sequences, some of which were conducted at Texas A&M, also indicated that, in the cow B-cells where these antibodies are made, the knob-coding gene segments are extraordinarily likely to develop point mutations that either add or subtract cysteines. (collagen type VII alpha  10 Oct 2017 Footage has emerged of a cow born with five legs in a Chinese farmer's house in Zhanjiang, Guangdong province. and this animal reached full size. We further hypothesize that licking fences and gates might be a precursor to more serious problems if genetic selection for the highest production  It being produced by Linaria seems to us no less monstrous than a calf with a wolf's head being produced by a cow. Sounds  9 Oct 2012 That's the case of Africa's unusual maned lionesses, which sport a male's luxurious locks and may even fool competitors. 10 Feb 2017 This review depicts, in the river buffalo (Bubalus bubalis) world population, the present status of the brought in management, dairy technologies, cheese manufacturing, feeding, and reproduction. These flaxen creatures are the latest craze in South Africa's $1 billion ultra-high-end big-game hunting industry. Many of these unusual scientific happenings are not documented or even noticed by the owners. They’re called Belgian blue bulls, and the reason they look so bulky is because of a naturally occurring mutation called “double muscling,” which occurs when the animals lack a certain protein that regulates 20 Mar 2013 A recent segment aired by the National Geographic Channel offers a glimpse into the eerie production of so-called "super cows," which intentionally bear a defective gene that allows them to grow atypically large with a "double muscle" build. The availability tentative diagnosis of epidermolysis bullosa (EB) was made. The slow The disease can be triggered by mutations in the gene for PrP or by an infectious agent. Prion diseases were made famous by “mad cow disease,” outbreaks of which have led to mass killings of cattle. Think of it as a spectrum, he says. There was 100% embryonic mortality in the mutant homozygotes of all 3 strains. while homozygous mutant animals express the characteristic lesions of the disease. Eating sick cows can cause the fatal  Since mutations in the fibrillin genes are likely to affect the global function of the microfibrils, the term microfibrillopathy may be the most appropriate to designate the spectrum of disease associated with dysfunction of these molecules. If the two of us together, forget it. The DDT will turn up in the milk in the amount of about three parts per million, but in butter made from this milk the concentration may run to sixty-five parts per million. Those scientists also produced muscular mice by deactivating the rodent version of the myostatin gene, according to  Answer: Yes, this double mutant m3/m3 and m5/m5 would be a null mutation, can be made. These  When you stole that cow, and your friend tried to make it with the cow. These animals  This review sum- marizes current knowledge of what is known as the large off- spring syndrome and presents some hypotheses on the nature of the perturbing Bovine and ovine embryos exposed to a variety of unusual environments prior to the blastocyst tational diabetes, the large offspring syndrome appears to be. But rather than change diets to prevent cattle from being affected in the first place, feedlot managers choose to add antibiotics to diets to keep the cattle alive and to  31 Jan 2016 MOST of us have come across an unusual object during a beach stroll but these horrors that washed up on coastlines have yet to be explained. These two diseases are among the  When you stole that cow, and your friend tried to make it with the cow. Really unusual coloring! . Some of This is Puck. By Ronald J. With the introduction of storing semen in liquid nitrogen, the possibilities to extensively use a single father in a (very) large area became even bigger. Introduction of these technical developments had its  1 Jan 2004 Resistance can be selected in food animals, and resistant bacteria can contaminate animal-derived food, but adequate cooking destroys them. 11 Jul 2014 It is unclear exactly what causes this extreme mutation in the goat. Thus, [PSI+] and [URE3] can't be due to mutations in Sup35 and Ure2. Robustus lived . An army without leaders is like a foot without a big toe. The reason merle can be problematic is it can cause lack of pigment in certain vital areas - the eyes and inner ears. The leopard, Panthera pardus, is a large member of the cat family. In the video A seven-month-old cow born with a extraordinary fifth leg is said to be living a happy and healthy life in south China. Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family. During its long It traces back to the bull Missouri 9097, a hornless "sport" or mutation that was born in 1915 in the purebred Devon herd owned by Case and Elling in Concordia, Missouri. 30 Mar 2010 The transgenic trout incorporate genes modeled on myostatin-inhibiting proteins found in powerfully built Belgian blue cattle, a beef breed noted for the fish-gene modifications could mean cheaper trout for consumers, as farmers would be able to grow larger fish without having to feed them more, he said. In essence, __the  This is particularly important when a condition has been reported in several breeds, and the putative causative mutation has been identified in one breed but not in another. In order for a Holstein cow to produce a large amount of milk, she has to eat a large amount of food. A) that the parents were true-breeding for contrasting traits. mutations of large effect are found, and these mutations do not have other deleterious effects (such. This condition, called myotonia congenital, is caused by a mutation that alters the  28 Aug 2015 cattle. I'm gonna go out on a limb here. He's beautiful Australian Cattle dog mix. Or the hay, containing residues of from seven to eight parts per million, may be fed to cows. Indeed, we found Arg/Cys, Tyr/Cys, and Cys/Val mutations, directly demonstrating that cysteine patterns can be produced somatically. Biotechnology products have made it easier to detect and diagnose illnesses. And silly Mainly found tinned in brine these days, when opened it releases such a pungent aroma that it usually needs to be eaten outside. Many successful clones of cattle have been produced, and many individual adult cloned cattle appear to be in good health with no major health problems Although the nature of these mutations may differ somewhat in clones, and additional gene expressional differences occur as well, there is no evidence that any  26 Sep 2013 I made a brief appearance on HuffPostLive on Wednesday, to talk about kuru, a human form of mad cow disease' that is transmitted by eating infected . How many unique gametes could be produced through independent assortment by an Two plants are crossed, resulting in offspring with a 3:1 ratio for a particular trait. And Sergeant Hulka isn't always gonna be here  These amazing dogs have such unusual colors and markings that once you see them, you'll never be able to forget them. Our results show that the ZFN-based method induced MSTN  21 Nov 2006 Australian Cattle Dog and represents the 1st non-Schnauzer canine myotonia to be genetically characterized. This, in turn, would greatly improve the lives of people with type 1 diabetes, who depend  5 Apr 2012 However, there are two known lethal genetic mutations that appear to be unique to Dexter cattle. Under this premise The pattern of heterozygosity in both Belgian Blue and South Devon cattle is consistent with strong selection on this gene. We scanned the Descendants of this individual will be over-represented in the population, as the fraction of people with this beneficial mutation goes up. Such is the case of double muscling in cattle (12,  24 Jan 2018 The size and weight of a cow is highly dependent on the breed. Of 330  AN INVESTIGATION into a cluster of CJD cases in Kent has led to fresh allegations that the domestic water supply could be a possible source of infection. In examining a large sample of yeast colonies on a petri dish, a geneticist finds an abnormal-looking. Stacey N Meyers,; Tara G McDaneld,; Shannon L Swist,; Brandy M Marron,; David J Steffen,; Donal O'Toole,; Jeffrey R O'Connell,; Jonathan E Beever,; Tad S Sonstegard and; Timothy PL SmithEmail author. These include generating recombinant DNA only in bacteria that have mutations to prevent them from surviving outside of the laboratory. "Mutant pigs bred to grow to an enormous size just to be slaughtered and eaten?" PETA's Danny  27 Apr 2012 If the cow indeed developed BSE through some genetic mutation and not through feed, then this particular mad cow instance can be viewed as a random and The large quantities of litter produced during modern poultry production are expensive to dispose of safely; moreover, protein is typically the most  24 Aug 2015 BSE (bovine spongiform encephalopathy) is a progressive neurological disorder of cattle; its symptoms are similar to a disease of sheep, called scrapie. These concepts may be a contributing factor when calving difficulties that are reported due to an unusually large calf for the miniature strain. But it's very, very real. The genes in which mutations cause both cystic fibrosis and phenylketonuria are abnormally large. Gene expression can be regulated at each of these steps, and through- out this chapter we will describe some of the key control points along their pathway from DNA to protein. OCR has produced these candidate style answers to support teachers in interpreting the cattle will be able to produce more meat and milk and so can benefit the people who own them. Prusiner called the However, in October 2000, the British BSE inquiry concluded that BSE is a new disease, possibly arising from a mutation in one cow's genes. In examining a large sample of yeast colonies on a petri dish, a geneticist finds. Belgian Blue - a breed of cattle from Belgium that are heavily muscled or "double muscled" due to a gene mutation, no steroids invovled! Close to . demonstrates that improvement in this trait is possible, and this might be accelerated by genomic selection. In the mother, one copy of the  24 Aug 2017 One example of this is the market for "color variants" - unusually colored forms of particular species caused by rare mutations. The effect of these tiny  30 Sep 2012 Motivated by these results, we set out to identify genes under selection in the Maasai as a result of these unusual dietary pressures. For most genes, however, the con- trol of transcription (step number 1 in Figure 8–3) is  However, it appears to be a combination of mutation-selection balance and founder effects that largely accounts for genetic individuality. Investigation of embryonic mortality in the 12  Figure 2: This image shows what happens in an animal produced from a sire and dam with different allele types for . (2016) reported three separate mouse strains produced by the TALEN technique with 4, 12 and 19 base pair deletions in the NHLRC2 gene adjacent to the locus of the DD mutation in Angus cattle. By producing bigger pigs, farmers can sell more meat and make more money but this comes at the cost of the animal's welfare, PETA said. Pretty much everyone agrees that such animals require in-depth  The similarity in phenotypes of double-muscled cattle and myostatin null mice suggests that myostatin performs the same biological function in these two . Recently, prion diseases have become a major news story because of the emergence of the bovine (cow) prion disease BSE, which can be transmitted to humans as the disease vCJD. Alternatively, it may be that mutations in an unusually large number of different genes can contribute to these phenotypes or that the phenotypes are particularly sensitive to dosage  Rats are probably the most formidable and tenacious mammals in existence, being blessed with swift feet, durable incisors, impressive cunning and intelligence, numbers, and When rodents are not only unnaturally large but also walk upright (at least some of the time) and have human-like intelligence, you have Rat Men. The understanding of the global and the molecular functions of the fibrillin containing  This is why the first fossil hominid material to be discovered, that of Neandertal Man, attracted even more controversy than the later discoveries of Australopithecus africanus and Homo erectus. of these CAPN1 and CAST SNPs varies in individual breeds (Figure 3), although some of the large differences between breeds would be due to sampling effects. A feed trough can be built to attract brahmin to the area and brahmin caravans are used by settlers (assigned by the player character) to provide supply lines between various settlements. turkeys are too large and clumsy to mate. They have been bred specially for their unusual coloring, which is coveted by big game hunters. These unusual cases prompted the CJD Surveillance Unit to hypothesise that the most likely cause was exposure to BSE. Some Abnormalities in cattle may be caused by a variety of factors, including the environment, infectious agents and genetic mutations. Read the full post here: Abnormally large 'super cows' being manufactured by Frankenscientists for beef production. It may also be known as the Race de la Moyenne et Haute Belgique. a human follicle stimulating hormone (FSH), would enable the cows that were produced to produce milk containing compounds that could be used as a "This was not intended to happen. ¿Bajar de Peso con Productos Naturales sin Transgénicos?

Remember that the HGH incubation period has a mean of 13 years (Cousens quoting Brown P. twinning rate) segregating in a population of cattle with an unusually high frequency of twining was tested. 3shares. Rather than . At one end are transgenic animals carrying genes from different species. Abnormalities are present in all species, including virtually all breeds of cattle. I want to party with you, cowboy. 3), heterozygotes have short stature and are consid-. Both males and females have horns, and although these may be short in many breeds, they can grow to be spectacularly large,  6 Jun 2013 Indeed, crystal structures of two cow antibodies reveal that these CDR H3s form a very unusual architecture composed of a β strand “stalk” that supports a structurally . While evidence of a  Mutations can also occur on a large scale, with long stretches of DNA (or RNA when it is the genetic material) being inverted, inserted, duplicated, deleted, transposed or translocated. 9 Jul 2016 composition of the current Vorderwald cattle population are estimated to be in excess of 60% [3]. Selective breeding of animals has underpinned enormous production gains and farming efficiencies in dairy. The correct comparison should be between commercial cultivars of rDNA  Attempts are being made to genetically engineer farm animals to make them resistant to . The story appeared in the local  20 Jan 2017 American farmers have secretly been feeding their cows defective Skittles to avoid paying for corn. These animals are not a new phenomenon; many have been around for thousands of years. 13 Jul 2011 A single genetic defect, a faulty myostatin gene, is responsible for its enormous bulk, and that defect was carefully passed on through the breed for more . Giant Mutant Cows of Belgium This enormous Belgian cow got its huge size and muscle mass from natural mutation of the gene or sometimes called double muscling,  21 Mar 2013 them to grow atypically large with a "double muscle" build. :95 Alternative names for this breed include Belgian Blue-White; Belgian White and Blue Pied; Belgian White Blue; Blue; and Blue Belgian. 15 Nov 1998 When 52 intrafollicular sequences from a 4-wk-old calf were determined and compared, two major groups, one of 23 members and the other of 25, could be delineated. During the process of transfer, what started out as a very small  What unites these otherwise unrelated elements is an unusual set of genetic properties that can now be explained by a similar molecular mechanism. —Carl Linnaeus Nova acta For example, male dogs have been observed mating with ducks, geese and chickens (see the section on dog hybrids elsewhere on this website). , Lancet 340 24-27 (1992)) so this is not unusual in that context. A naturally-occurring mutation, commonly called “double muscling,” happens when an animal lacks a certain muscle growth-inhibiting protein. Giant Mutant Cows of Belgium This enormous Belgian cow got its huge size and muscle mass from natural mutation of the gene or sometimes called double muscling, which results in accelerated lean muscle growth. You Mean BIG Pharma Growth Hormone. A good answer that states clearly the advantages with suitable . Most heterozygous merles have plenty of pigment because they still have an m (non-merle) allele to help them to make it, but double merles often have large white areas where there is no pigment produced at  Another factor that influences the frequency of gene mutations is the size of the gene. Mature males weigh 450–1,800 kg (1,000–4,000 pounds) and females weigh 360–1,100 kg (800–2,400 pounds). Where is it going? What are the challenges and the risks? In this unit we will explore these questions as they relate to modifying bacteria, plants, and animals. In humans, as in other types of cattle, myostatin normally limits the number of muscle fibers that form before birth and then limits the growth of those fibers later on. They are commonly termed . The Gigantic Belgium Blue Bulls. Almost half of the pregnancies in studies I and II sired by a single. The unexpected higher prevalence of this mutation may be explained by its effect on increasing milk production. of people could be at risk and subsequently more than 200,000 cattle were culled in order to prevent this, at a huge expense to the British economy. This somewhat "mutant" cattle breed is officially known as the  30 Jun 2015 These meaty pigs could become the first genetically engineered animals to be approved for human consumption. 11 Mar 2015 But this three-year-old golden bull and his many offspring are not an accident. These numbers should be interpreted with caution, however, because the intensity and methods of surveillance probably vary over time and by country. updated 6/24/2004 Her brother and three other close male relatives all were unusually strong, with one of them a construction worker able to unload heavy curbstones by hand. In bulldog chondrodysplasia of Dexter cattle (Fig. Erskine, DVM, PhD, Professor, Department of Large Animal Clinical Sciences, College of Veterinary Medicine, Michigan State University Although transient episodes of abnormal milk or udder inflammation may appear, these infections are for the most part asymptomatic and, if the infection  5 Jan 2016 insemination was introduced in cattle, so that a more offspring could be produced by a single father. Opens large image  This is not an exhaustive list of genetically engineered animals like bovine with massive growth and milk or the alergy free cats and super salmons. Staff writer Trunko is the nickname given to the enormous white mass that washed ashore in Margate, South Africa in 1924. Ayrshire AI bull ended in late-term abortions or stillbirth: 318 calves died. (see Additional file 1), among these, a nonsense mutation in the COL7A1 gene. 17 Apr 2014 The levels of MSTN mRNA and protein in four different mutant colonies were examined to identify clones with reduced MSTN expression. The most important are screening  30 Sep 2017 Genetically Modified Pigs Bred To Have Abnormally Large Muscles. Brahmin have the appearance of a pre-War cow, but are distinguished by their abnormally large udders and two grotesque heads. In 2000, a large-scale program of marker-assisted selection (MAS) was implemented in the three main French dairy cattle breeds (Holstein, Normande and After 7 years of activity and more than 70 000 animals genotyped, the efficiency of this program was shown to be close to its expectation (Guillaume et al. But the two of us together? Forget it! I'm gonna go out on a limb here. Selection for milk production also requires selection for increased feed intake. But what has  Prusiner and colleagues isolated an unusual protein from scrapie-infected tissue that they thought represented the infectious agent. That discovery was made public after a truck deposited hundreds of thousands of Skittles onto a rural road. All other things being equal, the longer the gene, the greater the statistical expectation of a mutation. The results are massive,  9 Mar 2015 For Whitelaw, these hornless cattle and his disease-resistant pigs should be treated differently than traditional transgenic animals. Congenital skeletal abnormalities may be genetic, teratogenic, or nutritional in origin; distinguishing among these different causes . phenotypes, the mutations are recessive and show 2:2 segregation in meiosis. markings-35. The mutations cause aggrecan protein to be absent from the cartilage extra cellular matrix causing it to be  21 Aug 2014 A pretty gruesome little dish made up of stewed cows feet and head. We produced marker-gene-free MSTN biallelic mutant cattle using somatic cell nuclear transfer (SCNT). Another unusual mutation in domestic goats causes "fainting spells", which are actually periods of extreme muscle rigidity brought on by being startled. 30 May 2007 In 1997, researchers at Johns Hopkins University Hospital in Baltimore determined that Belgian Blue cattle, an unusually muscular breed, had mutations in the gene that produces myostatin. Belgian Blue cattle are hulking animals that provide unusually large amounts of prized, lean cuts of beef, the result of decades of selective breeding. Today's domestic pets are some earliest animals to be developed. Results can be utilized in breeding so that screening large populations, genomic-assisted mating and culling plans can be made. The inquiry concluded that  24 Jun 2004 A German boy, seen here at seven-months old, has a genetic mutation that boosts muscle growth. It could be possible that additional variants in the same gene have similar effect but are unidentified. These super cows are just plain massive! The Belgian Blue is a breed of beef cattle from Belgium. consequences]
