What to do if a hen lays soft eggs? Why do hens lay soft eggs and how to treat them?

The reason for the soft eggs is that the chickens absorb too little calcium, which is simply the lack of calcium.

The second way is to supplement with vitamin D

Vitamin D promotes cellular response to calcium ions.

You can eat some foods or pills rich in vitamin D.

The third method is to dry the eggshell, mash it and mix it in the food for the chicken (the main ingredient of the eggshell is calcium), and if necessary, let the chicken bask in the sun to promote the absorption of calcium.

Hens laying soft eggs may be caused by calcium deficiency, you can buy some calcium-supplemented feed or vitamin-supplemented feed for the hens, so that the hens will not become soft eggs when they lay eggs.

Lay soft eggs because the mother lacks calcium, and it is good to add some calcium to the chicks.

Calcium supplementation requires calcium supplementation for the hens.

It is possible to feed some shell powder, eggshell powder, calcium tablets.

The softness of the eggshell is the cause of calcium deficiency.

What to do if a hen lays soft eggs? The hen lays soft eggs. It's a lack of calcium. Give him plenty of calcium-based foods.

Soft-shelled eggs]: also known as thin-shelled eggs, the thickness of this kind of egg is thinner than normal, and the magnetic needle will be immediately broken when lightly bumped or pressed by the egg. Its causes are as follows:

1. The lack of minerals for making eggshells in the feed, mainly due to the lack of calcium or vitamin D, or long-term high yield, the calcium in the feed can no longer meet the needs of the chicken body to synthesize eggshells.

2. The feed is not evenly stirred, the match is not up to standard, or the calcium and phosphorus are not matched with souvenirs in the ratio of 2:1, which hinders the absorption of calcium. The lack of manganese in the feed affects the metabolism of calcium and phosphorus.

3. The ambient temperature is too high, the chicken's appetite is reduced, the feed intake is relatively reduced, and the amount of calcium ingested in the chicken body cannot meet the needs of the chicken body to form eggshells.

4. The chicken coop is narrow, dirty, damp, the density of the flock is too large, and the lack of exercise of the hen causes vasoconstriction, which affects the local blood circulation, so that calcium and phosphorus can not be transported to the eggshell component normally.

5. The function of the eggfront gland is not normal, and it cannot secrete sufficient chitin.

6. The hen is frightened before laying eggs, and the nerve function of the reproductive system is disturbed and disordered, which affects the division of chitin.

7. Due to mycotoxin poisoning, the reproductive tract is disordered, and the ovarian function is lost or degenerated, so that the chicken lays soft-shell eggs, or the egg production is reduced or loses the ability to continue to lay eggs. Severe flocks also do not fully ** after removing this toxin.

In addition, soft-shell eggs are also produced in the short term after the occurrence of disease, dosage, and vaccination.

The hen lays soft eggs, which is actually a lack of calcium, and the way for the hen to supplement calcium is relatively simple, you can feed sand, stones, furnace ash slag, or bone meal, fish meal.

There is also a certain proportion of liquid calcium in chicken feed, or calcium powder.

Under normal circumstances, the eggshell has a certain thickness and can withstand a certain amount of pressure, but for various reasons, sometimes the shell of the eggs laid by hens is particularly thin, or even soft-shelled eggs.

If only a few chickens in the flock often produce thin-shell eggs, soft-shell eggs, it may be a hereditary factor and should be eliminated, but if a considerable number of thin-shell eggs and soft-shell eggs appear in the entire flock, it may be caused by improper feeding management.

In particular, the lack of calcium or calcium and phosphorus ratio in the feed, vitamin D deficiency is the most important reason for laying hens to lay soft-shell eggs, thin-shell eggs, therefore, must be based on feeding standards, improve the feed ratio, appropriately increase bone meal, stone powder and other calcium-rich feed to meet the needs of laying hens.

The correct supply of calcium is: before the start of production, at the beginning of production, during the high production period and for breeders; In the summer, the temperature is high, and the laying hens eat less feed, so the calcium content of the feed should be increased to 4%.

The ambient temperature in the house is too high or too low: the temperature suitable for the laying hen is 13 25, when it exceeds 30, it will affect the appetite of the eggs, if the laying hens are at high temperature for a long time, it will also affect the absorption of calcium, so it is necessary to strengthen the ventilation in the house when the temperature is high. Conversely, when the temperature is too low, the hens will experience cold stress and the eggshells will become thinner.

Lack of trace elements and vitamins in the diet: Magnesium deficiency in the diet reduces the concentration of magnesium and calcium in the blood plasma, resulting in a deterioration in the quality of the eggshell. Vitamin D not only promotes the absorption of calcium and phosphorus, but also benefits the development of bones and eggshells.

When vitamin D is insufficient, even if the dietary calcium supply can keep up, it will cause the absorption of calcium and phosphorus to be impaired, resulting in the occurrence of small eggs, thin shells and soft shells produced by laying hens.

Chicken age is too old and long-term continuous production: when the laying hen continues to lay eggs for more than two years, then it will grow with age, the probability of laying thin shell and soft shell eggs is gradually increasing, and long-term egg production, will also cause disorder in the chicken body, so farmers must strengthen the feeding management, so that the eggs can recover physiological functions as soon as possible, to ensure the quality of egg production.

Precautionary measures. 1. Farmers can change the configuration of feed according to the nutritional needs of laying hens at different stages, and sometimes they can also adjust the composition of nutrition according to the weight, feed intake and egg production rate of laying hens.

2. It is necessary not only to ensure the cleanliness and quietness of the chicken coop and the surrounding environment, but also to achieve proper ventilation to ensure the fresh air of the chicken coop, so as to reduce the concentration of ammonia in the house.

3, do a good job of appropriate drugs, is also an effective measure to reduce the laying hens to lay soft shell eggs, in order to prevent laying hens from raw soft shell eggs, you can also properly add nutritious strong cod liver oil in chicken feed to help improve the production performance of laying hens.

Because of the lack of calcium and vitamin D in the feed, you can choose a feed with eggshell powder that contains calcium content, and giving the chicken more calcium will improve the situation.

Causes and prevention of thin-shelled soft-shell eggs produced by chickens:

1. Indiscriminate feeding of additives: Practice has proved that the rational use of additives can improve the quality of eggshells. However, at present, there are many kinds of feed additives used in China, and we must choose additives suitable for chickens, and grasp the reasonable dosage.

Otherwise, it will break the balance of various nutrients and normal substance metabolism in the chicken, and make the eggshell thin.

2. 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 soft-shell eggs. A chicken feeds 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, the effect is good.

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 calcium is 1 times more than phosphorus, which is the best calcium and phosphorus supplement feed for chickens.

3. Lack of vitamin D: Vitamin D can promote the utilization of calcium and phosphorus, regulate the balance of calcium and phosphorus in the blood, and help the formation of bones and eggshells. When vitamin D is deficient, even if there is sufficient calcium in the diet, the absorption and metabolism of calcium and phosphorus will be impaired, resulting in small eggs, thin shells, soft shells, decreased egg production, and reduced hatchability.

Therefore, the flock should be exposed to the sun for more than 2 hours a day and add an appropriate amount of cod liver oil to supplement vitamin D.

4. Water shortage: Water is not only the solvent of nutrients, but also one of the important nutrients. Water helps digest, absorb, transport nutrients and metabolites, excrete waste products and regulate body temperature.

Chickens and eggs contain about 64, 75 and 70 levels of water, respectively. Therefore, if the egg-laying hen cannot drink water for 24 hours, it will not lay eggs for 1 month, or the total egg production will drop by about 30, and the thin-shelled soft-shell eggs will increase significantly.
