What is meant by double muscling?
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.
Can humans have double muscling?
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.
Is double muscling good?
It is also beneficial for the consumer, as leaner meat may be favorable with regard to coronary and heart diseases [5]. Double-muscled (DM) animals produce very lean meat. They can be classified as an extreme type of late maturing animals [6]. They are often defined as animals with muscle hypertrophy.
Which breed has a special gene for muscling?
Genetic Background. Double muscling is an inherited condition that occurs in several cattle breeds. However, it is highly prevalent in only two breeds, i.e., the Belgian Blue and the Piedmontese.
Are Piedmontese double muscled?
Two of the breeds that possess the double muscle gene are the Piedmontese and the Parthenais. The Piedmontese was discovered in Italy 1897, and the Parthenais were found in France in 1893.
Why does myostatin exist?
Myostatin (also known as growth differentiation factor 8, abbreviated GDF8) is a protein that in humans is encoded by the MSTN gene.. Myostatin is a myokine that is produced and released by myocytes and acts on muscle cells to inhibit muscle growth.
What do you suspect causes the double muscling condition?
What do you suspect causes their double-muscle condition? Their DNA. Double-muscling affects… Both cows and bulls.
What is bully whippet syndrome?
What is Bully Whippet Syndrome? A disease of muscle growth, affected dogs are heavily muscled and quite athletic. It arises from a mutation in the MSTN gene, which codes for myostatin, a protein with inhibitory effects on muscle growth.
