Is there such a thing as an egg where each egg is a double yolk?

It is normal for all of them to have double yolk eggs. The reason for the formation of double yolk eggs is that the two egg cells mature at the same time and are separated from the follicle together and incorporated into the fallopian tube, and the albumen, shell membrane and eggshell are encapsulated in each part of the fallopian tube, so as to become a double yolk egg.

There is a special kind of chicken and duck is a high-yield double yolk egg, which is caused by the genetic reasons of poultry, the double yellow rate is high to become one of the stable genetic genes, passed down from generation to generation, such as Xingza 288 laying hens double yellow rate of 2, Gaoyou duck double yellow rate of 1 -14.

Why are double yolk eggs easy to pile up?

There is a special kind of chicken and duck is a high-yield double yolk egg, which is caused by the genetic reasons of poultry, the high double yellow rate has become one of the stable genetic genes, passed down from generation to generation, such as Xingza 288 laying hens double yellow rate, Gaoyou duck double yellow rate of 1%-14%. Double yellow duck eggs like Gaoyou duck have become a famous brand. If it is an ordinary chicken that lays double yolk eggs, it is likely to be caused by young hens, which have strong reproductive function and are too nutritious.

It is also very likely that someone goes to some large chicken farms to buy double yolk eggs and then wants to sell them for a good price. Usually the hen lays an egg every day, when the flock is frightened, such as a plane passing by, a dog barking, a car horning, the hen flies wildly, the abdominal pressure increases suddenly, crushing the "follicle slit", the hen will instantly lay two egg yolks, wrapped in egg whites within 24 hours, producing double yolk eggs. The chance of double yolk eggs on a normal chicken farm is around because they look larger and easier to identify, but they are mixed with normal eggs**.

If a chicken farm often has a large number of double yolk eggs, it is likely that the feeding environment of the flock is problematic, and the possibility of using ovulin is not ruled out.

The probability of the occurrence of double yolk eggs is not high, and it is estimated that it is no more than one in a thousand. At this rate, it is not difficult to run into it once or twice, but it is doubtful if it is "often". Someone in the UK once encountered 6 boxes of eggs all double yellow, and many ** have reported that this is an incredible "small probability event".

Are double yolk eggs more nutritious than regular eggs?

In this regard, Gong Yanchang, a professor of poultry science at Huazhong Agricultural University, said that the nutritional value is the same as that of ordinary eggs, and they can be eaten with confidence.

When it comes to which one is more nutritious, double yolk eggs and ordinary eggs, nutrition experts said that "double yolk eggs" are favored because it is relatively rare, and some folk customs regard "double yolk eggs" as "auspicious food" that can bring auspiciousness and peace to people, but in terms of nutrition, egg whites account for 28 and egg yolks account for 72 in the nutritional composition of an egg. Egg whites mainly contain protein, and egg yolks mainly contain yolk phosphoprotein, lipid yolk phosphoprotein, phospholipids, triglycerides, and cholesterol. Double yolk eggs only change the ratio of egg white to yolk, cholesterol and lecithin increase by 1% to 2%, but the total nutritional value of the egg does not change.

It is difficult to determine whether nutrients are separated and lost. In addition, the cholesterol content in double yolk eggs is high, so it is best not to eat them for patients with high blood pressure and high cholesterol.

Hello, I am Tutor Wendong, I have seen your question, I am sorting out the answer, in order to give you an accurate answer, please wait for three minutes to five minutes, you can receive the message after I finish. [than the heart] [than the heart] [than the heart].

Hello dear, I'm honored to answer for you. Hello, eggs are double yolk eggs, one is that it happens that the chickens in the chicken farm produce double yolk eggs on a large scale of tens of thousands of chickens in a chicken farm, sometimes you will encounter a batch of hens that start to lay eggs, and often the probability of laying double yolk eggs is relatively high. The chicken farm will pick out the double yolk eggs for centralized sales, after all, they can be sold at a good price.

For chicken farms, picking double yolk eggs is as easy as distinguishing a rooster from a hen. The second is the genetic factor of the chicken that lays the eggs, and there is a special one of the chickens and ducks that has a high yield of double yolk eggs, which is caused by the genetic reasons of poultry. The third is to specialize in the production of double yolk eggs.

A double yolk egg is an egg that contains two yolks in one shell. Double yolk eggs are usually much larger than normal eggs. The food that a hen eats will always contain a lot of calcium, especially during the laying period, when the demand is even greater.

If a hen has laid double yolk eggs, it means that her reproductive system is not normal.

There are two yellow (o) z z in an egg

Whether or not it is a double yolk egg is not a matter of pure probability. Whether the double yolk egg is affected by the egg age and environment of the chicken, the probability of the first egg double yolk is generally relatively high, and the proportion of double yolk eggs is very high in the first few weeks after the chicken has just laid the egg. After the egg age is long, the production of double yolk eggs will decrease, and the upstairs said that it feels about the same.

2.The eggs you buy in the supermarket are sorted and screened. My family used to pick out double yolk eggs (relatively large).

Sending relatives is one thing, and the size of the eggs affects **. My family is a free-range farmer, with a few thousand eggs per family, and there will be regular wholesalers to collect the eggs, and they will resell them to supermarkets or restaurants.

Eggs are uneven, how can people sell them? The egg skin is too thin, the color difference is too great, and the size is too big to pick out. And large eggs are not popular, ** should be low. Why? You go buy a pancake, will they put you a super large double yolk egg?

3.Upstairs said.

These eggs were originally used to hatch chicks, while double yolk eggs and multi-yolk eggs cannot hatch chicks.

can only catch up with this batch of eggs, or it may be that her chickens will lay double yolk eggs.

Hello, the eggs I bought are all double yolk eggs, the big and small ones are all double yolks, the probability problem, good luck.

Normal. Double yolk eggs have a lot of vitamins. When the hen is frightened and other external influences, there is irregular ovulation, and there will be double yolk eggs and multiple yolk eggs, but the probability of laying double yolk eggs is very low.

Technically, it is very difficult and costly to make double yolk eggs manually. I've never seen an artificial egg, let alone an artificial double yolk egg.

Some farmers also analyzed that due to the large size of the double yolk eggs, in order to facilitate packaging, the staff will select the "big ones" and put them together. Or, these eggs were originally used to hatch chicks, and the double yolk eggs could not hatch chicks, so farmers would take these eggs and sell them centrally, which may be two reasons for the concentration of double yolk eggs.

Double yolk eggs are not much more expensive than ordinary eggs, so they cannot be sold by "double yolk". On the other hand, the use of hormones in chicken breeding is currently banned in countries around the world, so no one has studied it and there is no commercial production. In fact, even if someone really uses hormones to "give birth" to double yolk eggs, the hormone affects the hen——— hormone is only used as a signal, which does not mean that the hormone will enter the egg.

Therefore, it is safe to eat double yolk eggs.

There are a lot of double yolk eggs on the market, which is caused by the hormones fed to chickens by unscrupulous merchants, and is a marketing method formed by them to satisfy the curiosity of some people.

The appearance of double yolk eggs is mainly due to the fact that in the process of egg formation, two yolks are discharged at the same time in the ovary of the hen, and the yolk falls into the oviduct and the flare, and enters the swelling part through the peristalsis of the oviduct, where most of the egg protein is ......formedWhen laying eggs, they become double yolk eggs, and the egg shape is particularly large. If the double yolk egg is a fertilized egg, it can also hatch the chick as usual, but due to the lack of oxygen**, the small life is suffocated and dies halfway. So in daily life, double yolk eggs have no hatching value.

If the chickens are supposed to be fine, if they are man-made, it will be terrible.

Are a lot of double yellows on the market synthetic?

Double yolk eggs are not artificially created.

In fact, the production of double yolk eggs is mainly due to the "egg production process" of hens, which is regulated by hormones in their bodies. However, hens that have just begun to lay eggs, the process of egg production is not proficient, there may be "abnormal hormone secretion", can not control normal ovulation, and produce two yolks in a short interval between the front and back, which will lead to the occurrence of double yolk eggs, so double yolk eggs have nothing to do with artificial hormones.

Tips for judging the freshness of eggs:

1. There is a tie at each end of the egg yolk to fix the egg yolk. But the longer it is stored, the less elastic the frenulum is, and the worse the ability to fix the yolk. Therefore, if you shake the egg gently, you can't feel the yolk shaking, and it is generally fresher.

2. After the egg is born, there will be a slightly rough outer eggshell membrane on the surface, which will disappear over time. As a result, the surface of the eggshell is not too smooth, hazy, and generally fresher.

3. There is an air chamber at the end of the big head of the egg, which reserves space for the thermal expansion and contraction of the egg on the one hand, and provides air for hatching chicks on the other hand. The longer the eggs are stored, the more water evaporates, and the larger the air chamber will be. When selecting eggs, you can observe through the light, and the smaller the air chamber, the fresher it is.

There are many reasons for the formation of double yolk eggs, the main of which are hormone secretion, startle and genetic mutations.

First of all, double yolk eggs belong to deformed eggs, and the cause of deformity has a certain relationship with heredity and genetic mutations, but this is not the main reason for the formation of double yolk eggs. According to scientific research, hens that have just reached the age of fertility are more likely to produce double yolk eggs than hens of other ages, and this is caused by the excessive hormone secretion of hens that have just become fertile.

Secondly, some double yolk eggs are caused by the poultry being frightened, resulting in flying and jumping, which causes some follicles to burst, and the yolk in the ruptured follicle may enter other follicles through the gap in the follicle, thus forming a double yolk follicle.

Characteristics and the probability of double yolk eggs

Outwardly, the double yolk egg is larger than a normal egg, but it is less noticeable, and the two yolks inside are similar in size to a regular egg. According to scientific research, under normal circumstances, the probability of birds laying double yolk eggs is about 1, even in China, which has the "four famous ducks" and "the king of double yolk eggs", the probability of Gaoyou Ma duck producing double yolk eggs is only about 1, which shows that double yolk eggs are indeed rare.
