This picture is of a breed of cow called a Belgian Blue. ... This seems a perfect example of how genetic engineering can be abused – but in fact, Belgian blues have not been genetically engineered . The breed was developed in the 18th century by selective breeding.
What is the science behind the incredible muscle mass in the super cows?
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 than a century before it was even known what was causing the cattle's impressive ‘double muscling.
Are Belgian Blue cows on steroids?
The breed of cattle have freakish muscle-bound bodies due to a naturally occurring gene mutation called ‘double muscling'. But many are convinced that farmers have been injecting the ‘bodybuilder bulls' with steroids sparking a furious row online.
Does double muscling affect cows and bulls?
Double-muscled breeding is done to get more meat and less fat. Backfat is generally found to be less in double-muscled cattle than in cattle with normal muscling. (Bailey, Mears, & Mir). Animals that are double-muscled have a higher carcass yield but this does come with new problems for the cattle.
Why do bulls hate red?
The true reason bulls get irritated in a bullfight is because of the movements of the muleta . Bulls, including other cattle, are dichromat, which means they can only perceive two color pigments. ... Bulls cannot detect the red pigment, so there is no difference between red or other colors.
Why is double muscling bad?
Some researchers have found increased numbers of fast-contracting myofibres – and these tend to be larger in diameter than slow-contracting myofibres. Double-muscled animals may produce meat with a rapid rate of post-mortem glycolysis , and it tends to be more pale than normal.
How long do Belgian Blue cows live?
When you consider that beef suckler cows such as the South Devon – who also carry the double muscling gene mutation but are not selected for it – can live over 20 years and produce up to 15 calves in that time, it is clear that systematically performing caesarean sections on a Belgian Blue cow is a severe curtailment ...
Can you eat a Belgian Blue cow?
The Belgian Blue's sculpted, heavily muscled appearance is known as “double-muscling”. Belgian Blue is a breed of beef cattle from Belgium. ... 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.

Why are bulls so strong?
The strength of today's bulls is largely due to their extreme muscle mass compared to their body weight , which has gradually increased over the centuries as farmers selectively breed their cattle, selecting only the biggest and strongest bulls to create the next generation of the herd.
Can humans be double muscled?
Myostatin-related muscle hypertrophy is a rare genetic condition characterized by reduced body fat and increased skeletal muscle size. Affected individuals have up to twice the usual amount of muscle mass in their bodies, but increases in muscle strength are not usually congruent.
Which breed is now known as the Brown Swiss dairy breed?
The Braunvieh was originally a triple-purpose breed, used for milk production, for meat and for draught work; the modern Braunvieh is predominantly a dairy breed. The Braunvieh breed was developed in America into the Brown Swiss breed, not to be confused with Swiss Brown, the English term for the original breed.
Are Limousin cattle double muscled?
The BLCS dubbed F94L as the ‘Profit Gene'. As a result of the high frequency of this gene in the Limousin population, most animals have double copies and exhibit its characteristics; increased muscle mass without increased calving difficulties, lowered fertility or longevity.
