Why is the outside of an egg shell harder than the inside?

It's an engineering principle, because the outer surface of the single family is ellipsoidal and disperses the external forces at any point, whereas the inside of the eggshell doesn't have that function because it's just the opposite.

The eggshell is deposited with calcium carbonate, which should make the protein vacuole soft.

Because the main ingredient of egg shells is calcium.

The composition of the eggshell is calcium carbonate.

The outside ingredient is calcium carbonate.

The outside of the eggshell should contain calcium.

Reasons for the thinning of egg shells:

1. When the eggshell becomes thinner, it indicates that there is a problem with the chicken coop environment.

Chicken farmers should remove chicken manure in time, strengthen the ventilation of the chicken house, and reduce ammonia and hydrogen sulfide in the house.

and other harmful gases. If the temperature of the house is too high, the chicken's feed intake is reduced, the intestinal absorption rate of calcium is reduced, the chicken's breathing is accelerated, and carbon dioxide is excreted.

The increase causes the concentration of carbonic acid in the blood to decrease and the eggshell to become thinner.

2. When the eggshell becomes thinner, it indicates that there is an imbalance in feed nutrition.

We all know that the main components of eggshells are calcium, phosphorus. When the hen hatches the eggs, the absorption of calcium and phosphorus in the body is synergistic, and the content of iron, magnesium, zinc, manganese, etc. in the feed will affect the absorption of calcium and phosphorus, and then affect the quality of the eggshell, which is likely to lead to the thinning of the eggshell.

Therefore, chicken farmers must pay attention to the proportion of mineral elements in the feed when feeding the feed, and add a certain amount of sodium bicarbonate to the feed.

To increase the concentration of carbonic acid in the blood, it is beneficial to improve the quality of eggshells.

3. When the eggshell becomes thinner, there are signs of old hens.

Under normal feeding conditions, the uterine glands of young hens can secrete calcium carbonate normally.

When it comes to old age, due to the deposition of fat in the body of chickens, the uterine glands of chickens will deposit a certain amount of fat, which in turn affects the secretion function of the glands, making the eggshells thinner and brittle.

When encountering this situation, chicken farmers should carefully check the health of the flock, and eliminate the chickens that are old and the egg production quality is not up to par as soon as possible to avoid unnecessary cost waste.

Tip: When eggshells become thinner, it is often a sign of disease. If the above situation, the chicken farmer is doing well, if the chicken coop has the situation of thinning the egg shell, it is very likely that the chicken ** has a disease. Escherichia coli, Newcastle disease.

Decreased egg production syndrome, infectious laryngotracheitis, etc. can cause endovascular disorders of the uterine gland, which affects the quality of eggshells. In the face of this situation, it is necessary to find out in time and carry out the first to avoid the quality of egg production.

Thick good. The main substance of the eggshell is calcium carbonate, and the eggshell is relatively thin, indicating calcium deficiency.

The thickness of the eggshell is determined by the amount of calcium when the hen lays the egg. Too thin because the hens are also deficient in calcium.

Solve the egg shell thin method.

a) Increase grams of calcium in the diet and observe changes in eggshell thickness. If the eggshell is thin, it is a calcium deficiency, and if the eggshell is deformed, it is a vitamin D3 deficiency and should be supplemented.

b) Calcium granules are supplemented once at night with a diameter of 2 3 mm.

3) Calculate whether the available phosphorus content in the diet is normal. Generally, the available phosphorus content in the early stage of egg laying can account for the diet.

4) It is necessary to pay attention to strengthening the ventilation of the chicken coop, clean up the feces in time, and prevent ammonia poisoning caused by high ammonia concentration.

5) The temperature in the chicken coop in summer is best kept at 18 23; At the same time, it is necessary to appropriately increase the energy and protein levels and mineral content of the feed, so that the normal nutritional needs of the chickens can be maintained even if the feed intake of the chickens decreases.

f) Minimize chicken stress.

The quality of eggshells is an important factor affecting the economic benefits of the poultry egg industry. At present, many chicken farms and chicken farmers often have the phenomenon of hens laying thin-shelled and soft-shell eggs, resulting in serious economic losses.

Lack of calcium and phosphorus in the diet: laying hens need a lot of calcium to form eggshells, and calcium deficiency will produce thin-shelled and soft-shelled eggs. A chicken eats about 130 grams of feed every day, but the utilization rate of calcium in the feed is only 60%, so the calcium in the feed alone is not enough, 3%-4% shell powder or high-quality lime, stone crushed grains must be added to the compound feed, or the snail mussel, eggshell, bone mash to feed the chicken, in order to supplement the lack of calcium and phosphorus.

Laying hens also need more phosphorus because the yolk contains phosphorus. The phosphorus requirement in the diet of chickens is that available phosphorus should be contained. Bone meal, calcium phosphate and other mineral feed contain more calcium and phosphorus, of which the ratio of calcium and phosphorus is 2 1, which is the best calcium and phosphorus supplementary feed for chickens.

Older hens: Older hens generally lay larger eggs, but their shells are correspondingly thinner. Therefore, it is advisable to feed laying hens for no more than 20 months, otherwise not only thin-shell and soft-shell eggs will increase year by year, but also reduce economic benefits.

There is no good or bad for this, the thickness of the egg shell depends on the feed composition, the egg shell is relatively thicker if the mineral content such as calcium is more, and the physical condition of the hen, if there are some diseases, it will also cause the eggs to have some deformities and the like, but generally the eggs sold in the market are no problem, you can eat them with confidence, and there is basically no difference in the nutrients.

Personally, I think it is better to have a thicker eggshell, because the thickness of the eggshell is determined by the amount of calcium when the hen lays eggs.

Whether the eggs are healthy or not can be known by observing the thickness of the eggshell. Choose eggs with thicker shells and a heavier feel when picking up, especially when choosing loose eggs.

The eggs are too small because the young hens are laying smaller eggs, or the chickens are sick, whether they are white crowns, colds, or infected with avian influenza; The old hen has a loose birth canal and lays relatively large eggs, but because of her old age, it is possible that the hen is not in good health.

As long as the eggs aren't bad, it's fine.

When you hold an egg in your hand, it is difficult to crush it, because the egg is oval, and when you hold it hard, it will be evenly distributed throughout the whole body of the egg, so it is difficult to crush.

This is not because the eggshell is harder. The main reason is that when pinching the egg, it is grasped by hand, so that the stress area of the egg is relatively uniform, and it is difficult to have a breakthrough.

On the one hand, when pinching raw eggs, because the force of the eggs is spread everywhere and the force is uniform, so it is not broken, on the other hand, when the eggs are evenly stressed, the force that can be borne is relatively large, of course, mainly because of its unique egg curve and scientific structure.

Of course, it's not because it's hard, it's because of the shape of the egg, and if the egg is under a lot of pressure, it will transmit this force to the whole eggshell, so it's particularly difficult to pinch it.

Because eggs are very elastic and eggs are relatively slippery, it is difficult to crush, and the material of the eggshell is easier to crush.

The eggshell is soft, what is the reason.

There may be several reasons why the eggshell is soft:1When the egg is too old, the shell will become soft and lose its elasticity.

2.The eggs are too new, the shell becomes soft and loses its elasticity. 3.

Eggs are frozen at low temperatures and heated at high temperatures, and their shells will become soft. 4.The shell of an egg is affected by changes in temperature and humidity and becomes softer.

5.The shell of an egg will become soft if it is contaminated, such as if it is stained with grease. 6.

There are lesions on the inside of the egg, and the shell will chain and soften. 7.The shell of the egg will become soft after the action of chemical or physical factors.
