The feed for geese should contain sufficient amounts of shell meal, dicalcium phosphate, limestone, bone meal or eggshell meal. At the same time, geese should be allowed to bask in the sun and exercise more to promote calcium absorption and digestion. In addition, the goose exercise is insufficient, drinking water is not enough, fright, intestinal inflammation and so on can affect calcium absorption, although there is enough calcium in the feed, still produce soft or thin eggs.
Therefore, calcium-rich mineral feed should be added to the feed, and a small amount of cod liver oil should be added to supplement vitamin D; Let the mother goose bask in the sun more to promote the body's absorption of calcium; Regular administration of antimicrobial drugs to prevent E. coli and salmonella infections; Anti-yolk-free eggs: intestinal parasites should be repellent regularly; Anti-double shell eggs: Attention should be paid to keeping the environment where the female goose lays eggs quietly to prevent cold.
**: 1. Continuous egg production: geese continue to lay eggs for a long time, which is easy to lead to physiological decline, often making the eggshell thinner or laying soft-shell eggs.
Therefore, improve the quality of feed, increase animal protein feed, and often bask in the sun, strengthen feeding management, and promote geese to recover physiological functions as soon as possible, in order to ensure the normal laying of eggs by geese.
2. Genetic factors: different varieties of geese have different eggshell quality, such as the eggshell of native species is thicker, and the eggshell of foreign varieties is thinner and easy to break. Therefore, the eggshell thickness of the variety can be increased by means of seed selection to reduce the egg breaking rate.
3. Egg laying time: generally the goose farm is fed at about 8 o'clock in the morning, the blood calcium concentration is high during the day, and the secretion of calcium in the goose egg 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 geese 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.
4. Age influence: Generally, older geese lay larger eggs, but the eggshells are correspondingly thinner. Therefore, it is advisable for female geese to be fed for 2 years.
5. Thyroid dysfunction: Thyroid dysfunction in the goose body will seriously affect the absorption and utilization of calcium, thus producing thin-shelled eggs or soft-shelled eggs. Feeding thyroxine tablets for 3-5 days can quickly harden the eggshells.
6. Moulting: The physiological changes during the moulting of the goose are greater, 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 geese to feed freely for 3-5 days, which can accelerate the artificial moulting, quickly resume egg production and improve the quality of the eggshell.

Soft-preserved eggs are usually caused by a lack of calcium.
Eat some feed or additives that are high in calcium. For example, shell powder.
-
Eat some calcium-containing foods.

What medicine to take, **, parrot lays soft eggs.
-
The eggs laid by the goose are all soft-shelled, indicating that the goose is seriously deficient in calcium, which is the reason for the production of thin soft-shell eggs. During the laying period, the bones of the goose itself will be dissolved and used to form eggshells, so the goose should be supplemented with calcium during the laying period and add some calcium nutrition to the feed.
-
Egg geese and breeding geese are overweight during the rearing period, which can lead to sexual maturity before the brightening of the hood; Light exposure can cause geese to mature earlier and weigh less. It is manifested by an early age of inertia and an increase in the number of deformed eggs (too large, too small, double yolk eggs, soft shell eggs). The peak laying period of premature laying geese is shortened and the total egg production is reduced.
Due to the interference of external stress factors (such as shock, etc.), there will be a stress response, and then it will disrupt the nerve function, endocrine gland function, cause fallopian tube secretion, and hypersystolic function, resulting in soft-shelled eggs or thin-shelled eggs. When egg geese suffer from salpingitis, it will also cause geese to lay soft-shell eggs, sand eggs, deformed eggs, and small eggs. Or due to infectious diseases, parasitic diseases, etc., the eggshell gland secretion disorder is caused, and the calcium has not been deposited outside the eggshell membrane, and the eggshell is discharged in advance, that is, "premature birth".
Most of the soft eggs are because of long-term egg production, resulting in their own calcium deficiency, insufficient calcium in the feed, and strong stress reaction, resulting in the production of soft-shell eggs. Strengthen prevention, regularly check the stool, and isolate the eggs immediately**. When it is found that the egg goose has metabolic soft-shell eggs, it should be immediately mixed with 5% waste sugar in the feed, or 5 kg of waste sugar per 50 kg of drinking water is dissolved and fed to the egg goose, and the goose will lay eggs normally after 7 days.
Usually the appropriate amount of mineral additives is added to the feed to provide sufficient green fodder.
Get more sunlight and spend no less than 6 hours a day. When it is uncertain what factors cause the goose to lay soft-shell eggs, you can consider whether it is caused by other goose diseases, that is, after feeding the sick goose with anthelmintic drugs, if the condition improves, it is caused by parasite infection, otherwise it is a metabolic disease.

Abnormal eggs (deformed eggs) laid by chickens include soft-shelled eggs, non-shell eggs, non-yolk eggs, double-shell eggs, double yolk eggs, etc., with soft-shell eggs and shellless eggs being the most common. Under normal circumstances, i.e. when nutrients are adequate (especially minerals), layers should not lay soft-skinned or thin-shelled eggs. The reasons why chickens lay soft eggs, that is, shellless eggs, are:
First, there is a shortage of minerals used in the manufacture of eggshells in the feed, mainly calcium and vitamin D; The second is that the eggshell gland function is abnormal and cannot secrete enough chitinin to form an eggshell; The third is that the eggshell of the egg has been prematurely produced before it is formed; Fourth, chickens are sick. Such as Escherichia coli and other causes salpingitis and causes soft eggs.
In summer, if the hens are not fed baking soda, soft eggs can also be caused. The feed of laying hens should contain sufficient amounts of shell meal, dicalcium phosphate, limestone, bone meal or eggshell meal. At the same time, chickens should be allowed to spend more time in the sun and exercise more to promote calcium absorption and digestion.
In addition, insufficient exercise, insufficient drinking water, fright, intestinal inflammation and so on can affect calcium absorption, although there is enough calcium in the feed, still produce soft or thin eggs. Therefore, calcium-rich mineral feed should be added to the feed, and a small amount of cod liver oil should be added to supplement vitamin D; Let the hens bask in the sun to promote the body's absorption of calcium; Regular administration of antimicrobial drugs to prevent E. coli and salmonella infections; Anti-yolk-free eggs: intestinal parasites should be repellent regularly; Anti-bivalve eggs:
Care should be taken to keep the environment where hens lay eggs quietly to prevent cold.
In addition, the lack of sand in the feed is also an important reason for chickens to lay soft eggs. Sand grains can not only promote the absorption of calcium, thicken the egg skin, at the same time, sand grains can also grind food, shells and trace elements into milky form, and promote absorption, promote the growth of chickens, do not lay soft eggs, and produce more eggs. Not only laying hens need grit, but broilers also need grit.
In general, after 7 days of additional sand feeding, the eggshell is relatively hard. According to the test, the weight of each 100 eggshells after 7 days of feeding large sand grains is 170 250 grams heavier than before feeding sand grains. At the same time, it can reduce the crude protein in the feces by about 50% and improve the utilization of feed.

Calcium deficiency. Caged geese are prone to laying soft-shelled eggs and thin-shelled eggs. The reason for the appearance of these two types of eggs is mainly because the amount of calcium ingested by geese does not meet the normal needs of the laying period.
If effective measures are not taken in time, it will cause the mother goose to have little production or stop production, and the quality of the goose group will also decline; Domestic geese are highly vigilant because they have been chased or beaten, which in turn affects the eggs they lay!
Preventive measures are based on calcium supplementation. There are a lot of calcium in various animal and plant feeds, but the content is not the same. If calcium is supplemented alone, eggshell powder and shell powder are the best, followed by bone meal and stone meal.
The advantages of eggshell powder are that the particle size is appropriate, the goose likes it, the absorption and transformation are also fast, and the effect is good.

Under normal circumstances, that is, when the town is fully nutritious, geese generally do not lay soft-skinned eggs or thin-shelled eggs. The reasons why the goose lays soft eggs are:
1. The minerals used in the manufacture of eggshells in the feed are insufficient, mainly lacking in calcium and vitamin D;
2. The eggshell gland function is abnormal, and it cannot secrete enough chitinin to form an eggshell;
3. The eggshell of the egg is still premature;
4. The goose is sick. Such as Escherichia coli and other causes salpingitis and causes soft eggs.
First, the timely elimination of older laying hens. During the laying process, laying hens secrete calcium carbonate in the uterine glands. >>>More
