Just a double yolk egg. Explanation 1

A double yolk egg refers to an egg containing two yolks in one eggshell. Double-yolk eggs are usually much larger than normal eggs. The reason for the formation of a double yolk egg is that the two egg cells mature at the same time and separate from the follicle together and are taken into the fallopian tube. Each part of the fallopian tube is successively wrapped with albumen, shell membrane, eggshell and other materials, thus forming a double yolk egg. Egg. Sometimes multiple egg cells mature at the same time and are incorporated into the fallopian tube together, forming polyyolk eggs. Double yolk eggs can hatch chicks. If the "double yolk" eggs are indeed two fertilized eggs, then two chicks can be hatched. However, due to various reasons, the hatching effect is not ideal. If only one egg in a "double yolk" is fertilized, only one chick will hatch. The fertilization rate of double yolk eggs is similar to that of normal eggs. However, the number of dead embryos in the double-yolk egg group at the early and late stages of incubation was much higher than the number of dead embryos in the presumed normal egg group. Double-yolk eggs are larger than normal eggs, even much larger, which we can see with the naked eye. The larger size of a double-yolk egg means that the space inside the egg is larger, but this does not mean that the chicken embryo has a larger space for growth. The double yolk egg is indeed one circle larger than the normal egg, but after all, it is not twice as large. However, this larger space has to accommodate one more chicken embryo. On average, the space occupied by each chicken embryo Compared with normal eggs, it is much less. This in turn directly affects the consumption of nutrients and oxygen, the movement of the chicken fetus and the subsequent breaking of the shell. The chicks in double-yolked eggs are generally underdeveloped and weak, and breaking the shell becomes a high threshold. And most of them can only slowly run out of oxygen and energy, unable to reveal the brilliance of life. Double yolk eggs are not only much larger than normal eggs, but also have thicker shells. During the process of pecking the shell of a double-yolked egg

, the chick needs to change its body posture from time to time to change the angle of pecking the shell, so that it can penetrate the eggshell in a shorter and faster time. However, after the chick in the double-yolk egg is fully developed, the bodies of the two chicks occupy almost all the space in the egg. It is extremely difficult to change the posture of the body or even move. matter.

Gaoyou double yolk eggs Gaoyou double yolk eggs are a local specialty of Gaoyou, Jiangsu. The double yolk eggs in Gaoyou are mainly duck eggs, which are about the same size as goose eggs. The production areas are mainly concentrated in the Gaoyou Lake area. It is said that it is related to the water quality of Gaoyou Lake and the fish and shrimp.

Explanation 3

A double-yolk egg refers to an egg containing two yolks in one eggshell. It is usually much larger than a normal egg. Double Yolk Egg Double Yolk Egg

It is formed because two egg cells mature at the same time and break away from the follicle together and are taken into the fallopian tube. Each part of the fallopian tube is successively wrapped by albumen, shell membrane, eggshell and other substances. Sometimes multiple egg cells mature at the same time and are incorporated into the fallopian tube together, resulting in polyyolk eggs. This is similar to the process of forming fraternal twins in humans, but it is fundamentally different. Fraternal twins are two eggs released by a woman when she ovulates and are fertilized at the same time, resulting in two different fertilized eggs that eventually develop into twins. The egg cells in double-yolk eggs are not fertilized and therefore cannot hatch into chicks. The production of double-yolk eggs by poultry is often related to the abundance of food and the health of the poultry. Double yolk eggs contain two yolks and are very nutritious and are very popular among the public. Nowadays, people have begun to artificially cultivate double yolk eggs, and there are manufacturers that specialize in selling double yolk eggs. However, some people believe that double-yolk eggs are produced by female chickens due to endocrine disorders and other physiological reasons, and it is best not to eat them in excess. However, natural double-yolk eggs are still rare.

Introduction Egg white accounts for 28% and egg yolk accounts for 72%. In a nutshell, most of the nutrients in an egg are concentrated in the yolk. The two yolks of a "double yolk egg" are the same size, so their nutritional value may be twice as much as that of a single yolk egg. Ingredients Egg white: mainly contains protein.

Egg yolk: mainly contains yolk phosphoprotein, lipophosphoprotein, phospholipids, triglycerides, cholesterol; phosphorus, sulfur, calcium, chlorine, potassium, sodium, magnesium, iron; VA, VE, VB1, VB2, niacin, pyridoxine Acid, pantothenic acid, biotin, folic acid, VD; lutein, zeaxanthin, cryptoxanthin, etc.

Conclusion 1

Double yolk eggs can hatch chicks. If the "double yolks" are indeed two fertilized eggs, then It is possible to hatch two chicks, but due to various reasons, the hatching effect is not ideal. If only one egg in the "double yolk" is fertilized, only one double yolk egg can hatch.

One chick. The fertilization rate of double yolk eggs is similar to that of normal eggs. However, the number of dead embryos in the double-yolk egg group at the early and late stages of incubation was much higher than the number of dead embryos in the presumed normal egg group. Double-yolk eggs are larger than normal eggs, even much larger, which we can see with the naked eye. The larger size of a double-yolk egg means that the space inside the egg is larger, but this does not mean that the chicken embryo has a larger space for growth. The double yolk egg is indeed one circle larger than the normal egg, but after all, it is not twice as large. However, this larger space has to accommodate one more chicken embryo.

Conclusion 2

This is similar to the formation process of human fraternal twins, but there are essential differences. Fraternal twins Double-yolk eggs

Double-yolked eggs are two eggs released by a woman when she ovulates and are fertilized at the same time, resulting in two different fertilized eggs that eventually develop into twins. The egg cells in double-yolk eggs are not fertilized and therefore cannot hatch into chicks.

Which is more nutritious, double yolk eggs or ordinary eggs? "Double yolk eggs" are favored because they are rare. Some folklore will say " "Double-yolk eggs" are regarded as "auspicious foods" that can bring good luck and peace to people. It is a joy to occasionally find a "double-yolk egg" among the eggs you buy. But in terms of nutrition, the nutritional content of an egg is 28% egg white and 72% egg yolk. Egg whites mainly contain protein. Egg yolk mainly contains yolk phosphoprotein, lipophosphoprotein, phospholipids, triglycerides, and cholesterol. The nutritional value of eggs is mainly concentrated in the yolk. However, this does not necessarily mean that the nutritional value of double-yolk eggs is higher. If double-yolk eggs are produced by ordinary chickens under external stimulation, will the nutrients be separated? Loss is difficult to determine. Experts say: Many people believe that double yolk eggs have higher nutritional value. This view is also wrong. Even if double yolk eggs are really double yolk eggs, the composition of egg white and egg yolk has not changed. Moreover, the two yolks in a double-yolk egg are much smaller than a normal egg yolk, and the ratio of yolk to egg blue has not changed much. Therefore, there is no difference in nutritional value between double yolk eggs and ordinary eggs.
