What medicine to take for thin egg shells, and what is missing when egg shells become thin? 5

Now the requirements are strict, do not use drugs, use feed additive chitorubin.

That's it. 1. Genetic factors.

Different breeds of chickens have different eggshell quality, such as the eggshell of native varieties is thicker, and the eggshell of foreign varieties is thinner and easy to break. Xinyi can use seed selection methods to improve the eggshell thickness of varieties and reduce the egg breaking rate.

2. Egg laying time.

Generally, the chicken farm is fed around 8 o'clock, the blood calcium concentration is high during the day, and the calcium secretion of laying hens in the egg laying process is sufficient, so the eggshell produced in the afternoon is thicker. The eggs laid before 10 a.m. are usually formed at night, and the hens are mostly in a resting state at night, with little feed intake and low blood calcium concentration, so the eggs laid in the morning are generally thinner eggshells.

3. Continuous egg production.

Hens lay eggs continuously for a long time, which can easily lead to physiological decline, often making the eggshell thinner or laying soft-shelled eggs. Xinyi, improve the quality of feed, increase animal protein feed, strengthen feeding management, and promote the recovery of physiological functions as soon as possible, in order to ensure the normal egg production of chickens.

4. Thyroid dysfunction.

Thyroid dysfunction in chickens will seriously affect the absorption and utilization of calcium, resulting in thin-shelled eggs or soft-shell eggs. Feeding 3-5 days of thyroxine tablets can quickly harden the eggshell.

5. Moulting. The physiological changes during the moulting of the hen are larger, which will also make the eggshell thinner and the broken eggs increase. Therefore, during the moulting period, the whole barley should be used for the chickens to feed freely for 3 to 5 days, which can accelerate the artificial moulting, quickly resume egg production and improve the quality of the eggshell.

6. Age influence.

Older hens generally lay larger eggs, but correspondingly thinner shells. Therefore, it is advisable to feed laying hens for 2 years.

How much thyroxine does 10,000 chickens feed per day?

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.

Under normal circumstances, the shell of eggs is relatively hard, but when we buy eggs, we will find that the shell of some eggs is very thin and transparent, and it will sink down when it feels soft to the touch. In fact, the reason for this phenomenon is that the eggs of the chicken because of the unbalanced feed or too old and other factors caused by the lack of calcium, the eggs will be soft-shelled, this kind of eggs are not any problem to eat, but the nutrition may not be as good as the hard-shell eggs, and the soft-shell eggs because the shell is thinner, the shelf life is significantly shorter than the hard-shelled eggs.

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.

1. Calcium deficiency: laying hens need a lot of calcium to form eggshells, and calcium deficiency in the diet will produce thin-shelled eggs or soft eggs.

2. Phosphorus deficiency: Phosphorus plays an important role in the formation of bones, eggshells and body snarls of chickens, as well as the utilization of carbohydrates, fats and calcium. Hens, in particular, need more phosphorus because egg yolks contain more phosphorus.

3. Lack of vitamin D: Even if the calcium and phosphorus in the diet are sufficient, it will cause obstacles in the absorption and metabolism of calcium and phosphorus, resulting in small eggs, deformed, thin shells and soft shells, and decreased egg production and hatching rate.

4. Poor ventilation of the chicken house: the helium concentration is too high, which causes respiratory ammonia poisoning, which causes the chicken to lose more carbon dioxide, resulting in the formation of calcium carbonate and the lack of carbonate ions, which affects the absorption of calcium and causes the production of thin-shelled eggs from the slag.

5. Continuous egg production: hens continue to lay eggs for a long time, which is easy to lead to the decline of physiological functions, often making the eggshell thinner or laying soft-shelled eggs.
