Why do chickens eat food with sand when they eat it.

You must have seen that when the chicken eats rice and wheat grains, it always has to dig and peck in the east and west, and eat some sand, gravel or cinder and other things, why does the chicken have such a strange habit? Actually, it's not because it loves sand and gravel, or because it has a weird stomach that can digest sand and gravel, they just use sand and gravel to help digest food. We know that chickens and birds have no teeth and cannot chew their food when eating, so when they eat, they have to swallow food directly into their esophagus and store it in a food bag called a chicken gizzard.

After eating the sand and gravel, it is also stored in the chicken gizzard, which is extremely tough, and the inner wall of the chicken gizzard has a layer of yellow and tough wrinkled skin. The food and the sand and gravel are mixed together after entering the gizzard, and the edges and corners of the sand rub against the food under the strong wriggling of the bag made of the thick muscles of the gizzard, and after a while, the food is quickly ground into a paste and absorbed. What's more, before the food enters the chicken gizzard, it has been stored in the chicken gizzard and glandular stomach for a period of time, and has been subjected to the action of various digestive juices, and has been initially processed into a relatively soft and pasty chyme, and the chicken gizzard is much less labor-saving to grind.

Among the animals, not only chickens do not eat sand and gravel, but also pigeons and other birds. It's just a habit that they have developed over a long period of time to adapt to survival.

Chickens have no teeth, what to eat to help digestion!

Broilers eating sand can help digest the feed and are beneficial.

The beak of the chicken is, which is more suitable for pecking food, but the chicken has no teeth and cannot bite the food, no matter how big the food, as long as it can be swallowed, the chicken will swallow the food into the stomach. Food that is swallowed in the esophagus is extremely difficult to digest because it has not been chewed. Therefore, the entire digestive structure of chickens does not have only one stomach like humans, and the food is chewed and swallowed directly into the esophagus and into the stomach.

In order to be able to digest food better, chickens have two stomachs, one is the glandular stomach at the lower part of the neck, and the other is the hungry stomach in the belly. The glandular stomach has a very large digestive gland, when the food enters the glandular stomach, it stays in the glandular stomach for a short time, and when it is coated with a layer of digestive juice, it will immediately enter the hungry stomach.

Hungry stomach believes that anyone who has killed chickens knows that after we disemboweling the chicken, the dark red hungry stomach is taken out, and it looks like a large stomach, and if you cut it open with a knife, you will see that there are particularly thick muscles, and in fact, there is not much room for real food. When we remove the incompletely digested food from the stomach, we will see a layer of yellow corneum, and then the whole stomach can be used to make delicious food after the corneum is removed.

After dissecting the hungry stomach of the chicken, we see that the undigested food is actually still intact, that is, the food is not effectively digested in the first stomach of the chicken, and the first stomach is only equivalent to a storeroom. And food is digested after it enters the hungry stomach. However, in order to get timely and effective digestion in the hungry stomach, the food needs to be broken, and the grit in the stomach eaten by the chicken at this time plays a more critical role.

The reason why the hungry stomach has relatively sharp muscles and a solid cuticular membrane is because the sand needs to grind the food in the stomach, and if there are no sharp and thick muscles, it is easy to hurt the stomach when rubbing back and forth. So, at this time, the sand plays a role in chewing the teeth in the hungry stomach. The main reason why chickens need to eat sand regularly is to improve their digestion.

If the chicken does not eat the grit in time, it will affect digestion, which in turn will affect growth and egg production. Free-range chickens do not need to feed the chickens with gravel, but the caged chickens, because there is no opportunity to eat the gravel, want to let the chickens grow fast and lay more eggs, ***, it is necessary to feed the chickens with gravel regularly.

In general, adding about 3% of grit to chicken feed can have several benefits: first, it can effectively improve the ability of chickens to grind feed; second, it can slow down the passage of food in the chicken's stomach and intestines; Third, it can make it easier for digestive juices to enter human chyme, promote nutrients to be better absorbed by the body, and improve the weight gain of broilers and the egg production rate of laying hens. However, the grit should be made of non-soluble, silica or granite grit, and the size of the grit should be between 2 mm and 5 mm.

It is normal for chickens to eat sand in order to grind the food in the stomach and promote digestion.

Chickens are going to eat sand to better grind the food.

Chickens have no teeth and cannot chew food, which adds a lot of burden to the digestion of the stomach. So the stomach of chickens is different from that of humans and has its special structure, which is divided into glandular stomach and muscular stomach. The glandular stomach is small and secretes gastric juice; The muscular stomach is large and the meat is fat, which is what we call the chicken gizzard, and its strong contraction can grind food.

In order to better grind the food, the chicken has to peck at some sand, stones, and small metals, and store them in the muscle stomach.

However, these things are too hard and will damage the stomach wall, so in the process of evolution, the inner wall of the muscle and stomach will gradually form a layer of yellow corneal membrane to adapt to the friction with sand and metal and protect the stomach wall from damage. The sand and metal in the muscle and stomach gradually become smaller and even disappear in the friction with the grain, so the chicken should constantly replenish these things, but not be "digested" by the chicken's inner gold.

Summary. Hello! Chickens eat sand because the sand species has some trace elements, which can supplement the essential trace elements in the chicken's body.

The stomach of the chicken is divided into glandular stomach and muscular stomach, especially the muscular stomach is more fat, its contraction force is also relatively strong, which is helpful for digesting food, of course, the chicken eats some sand and stones, it can better grind the food, especially in the case of some food is harder, the role of the stone is relatively large, which can reduce the damage of food to the stomach wall.

Why do chicks eat grains of sand?

High body temperature and rapid development. Generally, the body temperature of chickens is between, so it must be raised in a warm winter and cool summer, and a well-ventilated environment, in addition, the digestive tract of chickens is short, the metabolism is vigorous, and the growth and development are fast, so it is necessary to feed sufficient nutrition and easily digestible feed to meet the needs. Weak resistance.

Chicks, in particular, are susceptible to harmful microorganisms.

Therefore, in addition to doing a good job of environmental cleanliness and hygiene, it is also necessary to do a good job of prevention.

Easily frightened. Chickens are timid, especially chicks, which are easy to startle, the light ones are crowded, the growth and development are hindered, and the heavy ones trample on each other to cause disability and death. Therefore, raise chickens in a quiet place.

Rough management, sudden noise, intrusion of dogs and cats, culling, etc. can all lead to disturbances in the flock and affect growth.

Afraid of moisture. Chickens should be grown in a dry and ventilated environment, and some pathogenic bacteria and molds are easy to grow and reproduce if the environment is wet. If the inside of the house is damp, the chicken manure will ferment to produce toxic gases, making the chickens more susceptible to disease.
