The Belgian Blue Bull is a beef cattle breed native to Belgium, the Belgian Blue Bull is different from the ordinary cow, they are muscular, the bull can grow to 1.2 tons, and the cow weighs 0.7 tons. Today Xiaobian will come to talk to you about the Belgian Blue Bull,
1. The history of breeding the Belgian Blue Bull
The Belgian Blue Bull is not the original Breed of Belgian cattle, but is the product of the hybrid breeding of a variety of cattle. According to records, in the north-central region of Belgium in the 19th century, the local native cattle and the British shorthorn cattle crossed, and the offspring were further crossed with the Charolais cattle from France, thus forming the predecessor of the Belgian blue bull.
By 1950, Europeans were increasingly inclined to use beef cattle with a large proportion of muscle, which led to a change in breeding direction. The real breakthrough occurred in the 1960s, when a gene that controlled muscle growth underwent an abnormal mutation, resulting in a new generation of Belgian Blue Bulls becoming unusually muscular and becoming proper "muscle cows".
2, the little secret of muscle crazy growth
Many people see the Belgian Blue Bull for the first time that it is the product of "genetically modified" technology, but it is not the case, in the 19th century, there is no concept of "genetically modified" in the world, let alone "genetically modified" technology, so the Belgian Blue Bull cannot be a product of "genetically modified" technology.
The reason why the muscles of the Belgian Blue Bull will grow wildly is actually a "genetic defect", one of their protein genes can not function normally, this protein is called "muscle growth suppressor", which is a hormone that regulates muscle growth, so the muscles of the Belgian Blue Bull will continue to grow wildly.
3. The difficult birth rate of cows is extremely high and the reproduction is difficult
Due to the lack of "muscle growth inhibitin", Belgian Blue Bulls have more developed muscles since the embryonic period. The cubs are too large, which is a challenge for breeding offspring.
In general, Belgian Blue Cow cubs can weigh an average of 44 kg when they are just born! In contrast to the large size of the cubs, the birth canal of the cow becomes very narrow because it is squeezed by the overly developed muscles of the buttocks. A large and a small, resulting in a difficult birth probability of Belgian blue cattle up to 95%, caesarean section has become the only choice for Belgian blue cattle to breed offspring, so the Belgian blue cow caesarean section surgery has become a technique that many farmers must learn. There are even many academic papers that have specifically discussed this operation.
Before it is over, because the muscle growth of the cubs in the womb takes away most of the nutrients, many Blue Cow cubs will be born with softened bones and cannot stand normally.
Bulls without fertility cannot avoid the harm caused by human transformation. Because muscle grows without restriction, most of the nutrients of the Belgian Blue Bull are concentrated on muscle growth;
This leads to malnutrition and imperfection of the bull's reproductive system. For example, the testicles are too small, the quality of sperm is insufficient, etc.; this makes it difficult for the Belgian Blue Bull to breed. The quality of bull sperm can lead to defects in the development of the cubs.
