"Four legs, six wings, three heads. ”
At that time, some people said that KFC used this kind of chicken, which is the so-called "six-winged chicken", which was very popular on the Internet for a long time, and was speculated by netizens in various P pictures.
There were many rumors about the six-winged chicken, and for a long time there were people who believed in the existence of the "six-winged chicken", but it was later proved that this claim had no scientific basis.
But the topic of chicken has never stopped, in order to meet the needs of the market, China has introduced a large number of new varieties of chickens from abroad - white feather chicken.
Relevant statistics show that China will eat more than 7 billion chickens almost every year, and 5 billion of them are white-feathered chickens, the biggest feature of this chicken is that the slaughter time is very short, only 40 days, which is what people call "quick chickens".
So slowly, some people said that the white feather chicken was a hormone chicken, and this statement caused some people to panic as soon as it spread, and some people were wrapped in an information cocoon, and even developed into a "talking about chicken color change".
From the chicks to the slaughter of 45 days, the meat is still very rich, so is this kind of chicken safe?Why does it grow so fast?
The white-feathered chicken first originated in the United States in 1888, and was later seen by a giant company in the United States The value of this species, so through genetic selection, the breed of faster-growing chickens was cultivated, that is, the white-feathered chicken.
Not only in China, but also in the world, white-feathered chickens are one of the most bred chicken breeds, especially in the fast food industry, and the vast majority of them use this chicken breed.
In the beginning, China did not have the technology to breed white-feathered chickens, so it could only be introduced from abroad, and later, with the unremitting efforts of Chinese experts, finally in 2019, the source of white-feathered chickens was mastered, and thus gained more and greater market discourse.
As soon as this broiler breed entered the market, it was quickly welcomed by the market and gradually became half of the broilers, with very high production efficiency.
In last year, China slaughtered a total of about 11.9 billion broilers, of which the three main varieties are white feather chickens, yellow feather chickens, and 817 miscellaneous chickens, accounting for % respectively.
The growth rate of white feather chickens is very fast, and the breeding time is also very short, which is very suitable for industrial large-scale production and processing, and China will eat nearly 5 billion white feather chickens a year.
However, it is precisely the relatively short cultivation process and the rich meat quality characteristics that gradually arouse people's questions about why it can have so much meat in such a short cultivation time
In 2012, well-known fast food brands KFC and McDonald's were exposed to using "instant chicken", which only takes 45 days to grow into a mature broiler.
In the perception of people at that time, the time for the general chicken seedlings to grow into adult chickens was 14 months, and the local chickens were about 4 or 6 months, and 45 days was simply "astronomical".
So slowly some people say that this "instant chicken" is a hormone chicken, which is very harmful to the human body, and if you eat too much, it will cause cancer.
People also began to think that this "instant chicken" was indeed unsafe, and began to "refuse" chicken and stop letting their children eat fast food.
Because foods containing hormones are indeed very large, if we eat this kind of hormone-containing foods for a long time, it will slowly affect the hormone balance in our own body, and there will be a risk of cancer for a long time, and it will also affect the growth of children.
The topic of "instant chickens are not safe" is also getting more and more discussed, but in fact, there is no scientific basis and evidence to prove that this "instant chicken" is hormone chicken.
And there is only one reason why some people firmly believe that chickens with such short growth cycles are hormone chickens, and that is that its growth rate is hard to believe.
Moreover, this broiler breed requires much less feed to grow one kilogram of meat than other chicken breeds, and the feed-to-meat ratio is not generally high.
What is the breeding process of white-feathered chickens?Why is there such a "rebellious" gene?
First of all, as we mentioned earlier, this broiler breed was first formed through multiple genetic selection and culture, in order to improve the growth rate of broilers and get more chicken benefits in the same time.
The cultivation process is very difficult, and experts have been collecting provenances and sequencing genes to produce better varieties.
In 1935, broilers grew to 1It took 90 days to weigh 3 kilograms, and then after half a century of selection, it took only half the time to grow to the same weight in 1986.
In 2000, broilers grew to 2It takes 6 kg in 48 days, and after 20 years, the broiler grows to 28 kg is enough for only 42 days, and the white feather chicken itself is an excellent genetic breed.
In the subsequent breeding process, the first step is to screen the eggs, and the relevant factories will use professional machines to select high-quality eggs, and then send them to the incubator for incubation.
The temperature of the incubator is the fastest suitable temperature for the eggs to break the shell, and after the eggs are broken, a new round of screening will be carried out to select the perfectly developed chicks and then breed.
When feeding white feather chickens, the feed used is carefully selected and proportioned, and some chickens in rural areas will use cereals and vegetable leaves to mix together to feed, but the feed of white feather chickens is strictly required.
The breeding process of white feather chickens is generally 45 days, and in the first 10 days, the feed is generally rich in protein and calcium, so as to promote the production of nutrients in the muscles.
The middle 20 days are specially formulated feed, which contains a change in the proportion of protein and vitamins, which needs to be re-proportioned to promote the rapid growth of the bones of white feathered chickens.
The last 15 days are cultivated with high-protein feed and fattened, which is why the chicken meat of white-feathered chickens is very sufficient, and all white-feathered chickens are cultivated under this scientific feed formula, which can also promote the transformation of feed to the greatest extent.
Moreover, the breeding environment of white feather chickens is also very strict, and the selected chicks will be sent to the farm for high-density intensive breeding.
The environment they live in has strict regulations on temperature, humidity and air cleanliness, so as to ensure the healthy growth of white-feathered chickens.
And its slaughter is also required, if in such a feeding process, there is no disease, then it can be slaughtered on the specified date, if there is not.
Of course, it is impossible to say that a little drug is not used, because under such high-density breeding, chicks are very easy to get sick.
If a chicken has a disease, the whole flock will be affected, so in order to avoid being infected by bacteria, they will also be vaccinated and use some anti-disease drugs.
However, all processes are carried out under strict requirements, the corresponding feed quality is adjusted, and there is a one-week withdrawal period.
During this period, they will wait for the natural metabolism of relevant drugs in their bodies, and will conduct multiple sampling surveys on this indicator before slaughter to detect the drug residue in the body.
Only those that meet the inspection and quarantine procedures of the animal husbandry department can enter the market, but the so-called hormones that are harmful to the human body are not added.
And for a long time, there have been clear laws and regulations in China, which are not allowed to feed broilers with hormones, and improper hormone feeding can easily cause the death of broilers.
So on the whole, white feather chickens from the chicks to grow into mature chickens, more than 40 days can be on the table, its genes account for 70% to 80%, the remaining 20% to 30% is thanks to the acquired feed, breeding environment.
White-feathered chickens are the most suitable broilers for factory large-scale farming, and their feed conversion rate is the highest among all poultry, and 5 billion chickens can save hundreds or even tens of millions of tons of grain every year.
Although the growth time is short, the meat is very tender and the taste is very delicious, and it is worth mentioning that this broiler breed has a relatively high lean meat rate.
In this way, the fat content is relatively low, and it is easier to digest and absorb some.
It is precisely because of the independent breeding of white-feathered chickens and the solution to the problem of provenance, so that China has realized the freedom to eat chickens, and among the food fed to the endangered species Siberian tigers, there are specially selected white-feathered chickens.
Because the general yellow feather chicken, although the meat quality is very chewy, the nutritional value is indeed slightly higher, but it does not meet the requirements of the Siberian Tiger Forest Park, except for the chicken head, chicken feet, chicken wings where the tiger can not eat, there is not much meat left.
The white-feathered chicken is relatively more meat on the trunk and has smaller limbs, so it has become the best choice for Siberian tiger feed.
Therefore, this kind of "instant chicken" is not actually a threat to the safety of the human body as rumored, it is a breed that is scientifically introduced, cultivated and further bred in China.
The white-feathered chickens we buy in the regular market are generally subject to strict quarantine standards, but it is indeed true that the overall nutritional value is not as good as that of ordinary chickensBut you can't have both, and under the low cost and high meat ratio, this is indeed the first choice in the market.
