In order to obtain benefits, humans do some things a little crazy. In addition to being slaughtered by people, animals in nature even do these things to them.
Have you seen Belgian Blue Bull with muscles and sticks? This kind of cow is about 1.5 meters tall, weighs more than 1 ton, and the heaviest one can reach 3 tons. It is full of large muscles on its body. It can grow 3 kilograms of meat crazy in a day. Don’t envy its figure. This muscle is exchanged for life.
In fact, a long time ago, Belgian 's blue cow was no different from ordinary cows. Until the 19th century, in order to improve the meat production ability of Belgian blue cows, people hybridized with British short-horned cows , and then further hybridized with French Charolai . From then on, this tragic animal was born.
Their survival meaning is not to cultivate the land or pull the cart, but to be sent to the slaughterhouse and become meals on the table. They have huge bodies as soon as they are born, and their muscles grow wildly, which makes them a little heavy and difficult to walk.
They were originally animals with both milk and meat. The mutations in their genes turned them into single meat animals. Although this beef has delicious meat and good taste, many of them have hereditary diseases and will die soon if not taken care of.
fried chicken is a favorite of many people, especially chicken chops, which are the main ingredient of burgers. Without chicken chops, the burger will lose its soul. According to statistics, KFC kills 850 million chickens every year, and in addition to other restaurants and people's dining tables, the demand for chickens is amazing every year.
German Free University and the University of Science and Technology have cultivated such a chicken that looks very strange and does not have a hair on its body, so it is called hairless chicken .
It is said that this hairless chicken is bred by a hybrid of German bald chicken and Chinese chicken. The egg production volume is 10%-20% higher than that of hairy chickens, and the growth rate is much faster than that of ordinary chickens.
But this kind of hairless chicken, which doesn't even have a coat, makes people feel goosebumps all over their body, a little disgusting and a little pitiful.
But they are more troublesome to use, and save the step of eating chicken and plucking feathers, which not only saves water, but also saves manpower and time. They also have disadvantages. Because they have no feathers, they are difficult to resist cold, and they are difficult to fight against parasites and sunburns, so they cannot survive independently in nature.
We all know that the combination of horses and donkeys will give birth to mule . Although horses and zebra have no intersection, scholars who are engaged in scientific research have used them to experiment and gave birth to zebras. They have horse figures, zebra stripes on their bodies, and are more docile in temperament, which also makes wild zebras on African grasslands more likely to be tamed.
long-haired pig is even more interesting. At first glance, you would think it is a sheep. It is a pig bred from Hungarian . It is a hybrid of wild boars and domestic pigs. Such pigs have strong disease resistance and better meat than domestic pigs. Therefore, this kind of long-haired pig is raised in most areas of Hungary.
and tiger lion beast , lion tiger beast . As early as 1799, when Britain colonized India, the British had a strange idea to lock the male tiger and the female lion together, and finally successfully produced a beast with a face that looked like a tiger and a body that looked like a lion, called the tiger lion beast. Later they locked the male lion and the tigress together, and indeed the lion and tiger beast was produced.
I have also heard of hybrid fish, such as Arhat fish , Parrot fish , and even more, they have made mice with human ears. What has the advancement of science brought to nature?
various research results on animals and plants have already had a great impact on our production and life. In addition to public discussion, scientific argumentation is also needed. After all, it is better to be cautious about food safety.
