What type of mutation is observed in the myostatin gene in double muscle cattle?
Although the expression of myostatin mRNA does not appear disrupted in Belgian Blue cattle, mutation analysis reveals an 11-bp deletion mutation in the coding region of the myostatin gene in Belgian Blue cattle that would be predicted to abolish the activity of the protein, as the truncated portion encodes the peptide …
What is double muscle syndrome?
Description. Collapse Section. Myostatin-related muscle hypertrophy is a rare condition characterized by reduced body fat and increased muscle size. Affected individuals have up to twice the usual amount of muscle mass in their bodies. They also tend to have increased muscle strength.
Which cattle breed is double muscled?
Belgian blue cow breed
The double-muscled Belgian blue cow breed. Double muscled animals have an increase in muscle mass of up to 20% greater than normal animals. The increased muscle is due to the fact that these animals have a mutation in a specific gene that normally is involved in muscular hypertrophy.
Why are Belgian Blue cattle so muscular?
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 muscle growth.
What causes double muscling in cattle?
Double muscling is the term used to designate a muscle hypertrophy characteristic of cattle and Texel sheep. It is due to a mutation in the myostatin (MSTN) gene, which encodes the growth-regulating factor myostatin. Muscle hypertrophy arises from an increased total number of fibers.
Why are Belgian cows so big?
What is the most muscular cow?
Belgian Blue’s
The Belgian Blue’s bone structure is the same as normal cattle, albeit holding a greater amount of muscle, which causes them to have a greater meat to bone ratio. These cattle have a muscle yield around 20% more on average than cattle without the genetic myostatin mutation.
What is the strongest cow?
Chianina
The Chianina (Italian pronunciation: [kjaˈniːna]) is an Italian breed of cattle, formerly principally a draught breed, now raised mainly for beef. It is the largest and one of the oldest cattle breeds in the world….Chianina.

What does it mean to be a double muscled cattle?
Double-muscled cattle refers to breeds of cattle that carry one of seven known mutations that limits and reduces the activity of the myostatin protein. Normally, myostatin limits the number of muscle fibers present at birth, and interfering with activity of this protein causes animals to be born with higher numbers…
What kind of cattle have double muscling alleles?
Double muscling is an inherited condition that occurs in many cattle breeds. However, it is most prevalent in only a few breeds such as the Belgian Blue and the Piedmontese breeds. The alleles of the locus have been given different symbols, of which mh and + for the double-muscled and the normal allele, respectively, are the most used.
What kind of beef breeds have double muscling?
Congenital Muscular Hyperplasia (Double Muscling) in Cattle. Congenital muscular hyperplasia (double muscling) is seen in several beef breeds, including Charolais, Angus, Belgian blue, Belgian white, South Devon, Santa Gertrudis, and Piedmontese cattle. This disorder is inherited as an autosomal recessive trait with incomplete penetrance.
Are there any examples of Beef Shorthorn with double muscling?
The Beef Shorthorn Cattle Society directors are also aware that there are examples of cattle within the Beef Shorthorn breed that appear to be exhibiting characteristics associated with a myostatin mutation. This is not a surprise given that the first documented case of double muscling was 200 years ago in Durham cattle.
