What causes double muscling in cows?
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.
Is double muscling good?
Double-muscled breeding is done to get more meat and less fat. Animals that are double-muscled have a higher carcass yield but this does come with new problems for the cattle. The meat from double muscled cattle is tenderer. “There is a persisting trend to improve carcass quality in specialized beef breeds.
Is double muscling bad?
Double muscling is due to a mutation of the myostatin gene. Myostatin mutations are pleiotropic in their effects, meaning that they affect a number of different body systems. Some of these gene effects are known to negatively impact the welfare of cattle.
Do Belgian Blue cows have horns?
The breed has a trait that allows its body to convert feed into lean muscle with a result the breed has less fat and more tender meat. They were originally bred as a milk cow and do offer a good quality and yield of milk….PHYSICAL CHARACTERISTICS.

What do you suspect causes the double muscling condition?
MUTATIONS IN THE MYOSTATIN GENE CAUSE DOUBLE-MUSCLING IN MAMMALS – Patent 1002068. [0001] This invention relates to factors affecting muscle development in mammals, especially livestock.
Which gene would you suspect causes double muscling?
Double muscling is a genetic syndrome and is caused by the mutation of the myostatin gene. The result of this mutation is that it causes the negative regulator of muscle growth to fail to function.
Why are Belgian Blue cattle so muscular?
Last Updated April 3, 2019. 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.
Is Belgian Blue healthy?
Health. The Belgian Blue is known for double-muscling, caused by a genetic mutation that prevents control of muscle development and leads to an increased number of muscle fibers. Some Belgian Blues may have underdeveloped reproductive tracts. Laryngitis and bronchopneumonia are also concerns in this breed.
How much is a Belgian Blue bull worth?
Our calves ranges from $360 to $2000 each depending on what you want. Delivery all states to all states and international as well.
What do you suspect cause the double muscling condition?
Double muscling is caused primarily by an increase in the apparent number of myofibres.
What are the disadvantages of Belgian Blue?
Cons
- Unsuitability for beginners due to special health needs.
- Higher nutritional needs than other breeds.
- Inability to thrive on pasture alone.
- Unsuitability for harsh environments, particularly high temperatures.
- Late maturity.
- Some difficulties with natural matings.
- Calving difficulties in purebreds.
Are there any breeds of cattle that have double muscling?
Here we report that the myostatin gene is highly conserved among vertebrate species and that two breeds of cattle that are characterized by increased muscle mass (double muscling), Belgian Blue ( 3) and Piedmontese ( 4 ), have mutations in the myostatin coding sequence.
Is there such a thing as a Belgian Blue Cow?
The Belgian Blue and the Piedmontese, another breed with myostatin problems, are viable farm strains of cattle. They can live, reproduce, give milk, and be consumed with no risk to humans. To themselves, however, these Conan-looking cows are less friendly.
What kind of mutation causes double muscling in cattle?
Here we report the myostatin sequences of nine other vertebrate species and the identification of mutations in the coding sequence of bovine myostatin in two breeds of double-muscled cattle, Belgian Blue and Piedmontese, which are known to have an increase in muscle mass relative to conventional cattle.
What kind of muscle disease does Belgian Blue have?
A visibly distinct muscular hypertrophy (mh), commonly known as double muscling, occurs with high frequency in the Belgian Blue and Piedmontese cattle breeds.
