Cattle rumination is a normal physiological characteristic, what is the process of cattle rumination

Cattle are large herbivores. They consume nearly 100 catties of forage every day. As long as less hay is added often, or when they come across fresh grass that they like to eat, they will try their best to eat it until their bellies are round.

But if the grass is not clean, or if their own saliva gets on the grass, the cattle will give up. They don't graze slowly. Instead, they swallow the dates and regurgitate them after they stop eating.

Ruminants are a kind of physiological sustenance of cattle and sheep ruminants.

Cows are different from other animals in that their stomachs are made up of four stomachs, ie. The rumen, reticulum, ovarian stomach, and amniotic membranes share different digestive functions. The rumen plays the role of fermentation, the reticulum plays the role of mixing, the milk stomach plays the role of drying the water, and the amniotic membrane plays the role of regrinding the food, and finally sends the food into the small intestine to absorb nutrients.

Once the cow stops eating or resting, therefore, it will reverse digest the food in the stomach when it is spit out, this process is repeated many times in a day in nearly ten hours, as a result, we see that as soon as the cow stops, the mouth will move, and the saliva will flow out of the mouth A lot of grass green, this is the cow's regurgitation of food, therefore, cattle should be cultivated in a reasonable time so that they have enough time to collect food and ruminate, so that they can be stronger and continue to serve humans.

The feeding time of cattle is 05 After 1 hour begins to ruminate, the digestive system of cattle must go through rumination to digest and absorb normally, no matter how full it is, cattle must chew cow dung, ruminants for about 20 30 minutes each time, chew about 40 70 times per mouthful. The length of crude fiber of ruminants must be sufficient for a day, and there is no certain effective crude fiber, which is not conducive to rumination of cattle, and in the long run, it is easy to cause rumen acidosis, forestomach slowness, rumen accumulation and other problems.

In order for cattle to gain weight quickly, they must be well fed and fed, both of which are indispensable. The greater the dry matter intake, the greater the daily weight gain and the higher the milk production. It is suggested that early calves can be appropriately fed, so that the cattle can open the skeleton and be properly fed until 8 9 are full; In the later fattening stage, cattle should eat as much as possible to facilitate the rapid fattening of cattle.

Through a combination of methods such as less feeding, adding putrefactive digests, and improving the palatability of feed, the cattle can eat as much as possible.

Cattle are a very unique creature, and the rumination phenomenon of cattle is that the food eaten by the cow will temporarily stay in the stomach, and then it will turn back and continue to chew.

Cattle digest the food that has been eaten in the stomach first, return from the stomach to the mouth by secreting saliva and chew the teeth for secondary processing, and then swallow the chewed food into the stomach for secondary digestion.

And if we look closely, we will find that the cow needs 6 hours or more of the time of the day to ruminate, which can make the grass in its stomach more soft and its stomach can be better protectedThis is the mystery of physiology, and this is also the difference between different species.

Cattle need about 6 to 8 hours a day to ruminate. Rumination can make the forage thinner and softer, and it can enter the digestive tract through the rumen relatively quickly, so that the cattle can eat more forage.

It is because the age of the cow is very old, and there is food accumulation in the body, which is not very digestive, so there will be rumination.

That's because when the cow first eats, it doesn't digest the food properly, so it has to do this operation, chew the food again, and then digest it into the stomach.

It may be that the feed is not nutritious and the cattle are infected with some bacteria, which is why this happens.

The cow has to return the grass and trees in the rumen to the mouth, chew again, secrete saliva for two stages of digestion, and then swallow it again into the rumen, the whole process lasts about 1 to 2 minutes, and 50% of the cows will ruminate, and regurgitate every 6-8 hours.

When the cow has finished eating the forage or is resting on the ground, people will see the cow's mouth chewing into a bolus and swallowing it again, which takes about 1 2 minutes each time, and the cow needs about 6 8 hours a day to ruminate. Rumination makes a large amount of forage thinner and softer, and passes through the rumen to the back of the digestive tract more quickly, so that the cattle can eat more forage.

The process of cow rumination is to put the ingredients in the sac into the mouth and continue to chew before it actually reaches the stomach and is absorbed and digested.

The process of rumination of cattle is to eat the food first, but because it cannot be digested, it is returned to the mouth to chew.

When a cow finishes eating, the food is swallowed into the mouth before the food is digested, and then chewed and swallowed.

After eating the grass, the cattle chew and swallow the grass, and then soak the grass in the stomach before entering the digestive tract through the rumen.

In fact, they will find that they return the food in their stomach to their mouths for chewing, and then swallow it, and there is such a process.

After eating, it is soaked in the rumen, then chewed, and then digested through the other stomachs in the last puckered stomach.

Although its mouth chews all the time, and it takes a long time for it to ruminate, the process is very laborious and requires a lot of patience.

When cattle are eating, the feed is generally swallowed into the rumen in a hurry without being fully chewed, and usually returns to the mouth at rest to chew carefully, a unique digestive activity called rumination. Rumination can be divided into four stages, namely regurgitation (the return of food from the stomach to the mouth), re-chewing, remixing of saliva, and re-swallowing. Rumination is a digestive reflex activity unique to ruminants, which is closely related to the function of the forestomach and the wrinkled stomach and the overall health of the animal.

Therefore, the observation of rumination activity in animals is of great significance for disease diagnosis and prognosis.

Generally, cows have four stomachs, so there will be rumination. But now in farming, it is generally possible to observe the health of cows by looking at their rumination. Preventing some diseases in cattle in advance is a good way to do so.

The average experienced farmer can see the problem by looking at it. So how should this phenomenon be observed and judged? Now let's look for the answer below.

1. Cow stomach structure.

Cows have four stomachs, only one true stomach, and the other three are caused by the change of the esophagus. Each stomach has a name, and only the wrinkled stomach is the real stomach, and there are three variants of the stomach: rumen, reticulum, and valved stomach.

It is the real gastric secretion of gastric juice. But all four stomachs can play an important role in digestion. There are many microorganisms in the rumen and digest most of the food; net, sifting out heavy things to eat, such as nails; The stomach is the function of squeezing and grinding food; The stomach is the main part of digestion.

2. Rumination characteristics.

After eating and chewing, it enters the rumen, and can then return to the mouth to continue chewing at rest. It's contemplation. There are four phases:

Food is returned from the stomach to the mouth, chewed, mixed with saliva, swallowed. Every time you go through this process. Rumination is related to the health of cattle and the health can be observed.

3. Slowing down of function.

Generally, it takes more than 40 minutes to ruminate once, and more than 5 times a night. But if the number of ruminations decreases, the time becomes shorter, and the number of times you chew the ball decreases, it may be a phenomenon of weakness. It is likely to be rumen food accumulation, gastric relaxation, flatulence, etc., or poisoning, metabolic diseases, encephalopathy and other diseases.

Therefore, the method can be detected as early as possible.

4. No more rumination.

If there is no rumination at all, the problem will be more serious, probably because the front stomach can be immobile and the stomach lining is paralyzed. If there are multiple stops, it may be reticulogastritis, chronic diseases such as tuberculosis. These diseases can devour cattle and ruminate for a long time, resulting in poor rumination.

The rumination of cattle determines the digestive function of cattle and also reflects the health of cattle.

The rumination of cattle is closely related to the health of cattle, and the health status of cattle can be known from the rumination of cattle. Some diseases can be prevented, or detected and ** some diseases in advance. Rumination should be taken into account in breeding.
