What does it mean for sheep to ruminate? How is rumination of cattle and sheep carried out?

Sheep rumination refers to the activity of herbivores regurgitating food balls through the rumen into the mouth, chewing and swallowing again. It consists of 4 processes: regurgitation, re-chewing, remixing saliva and re-swallowing.

Sheep ruminant can further grind the feed, while keeping the rumen an extremely anaerobic, constant temperature (39C-40C), pH value (constant environment, conducive to rumen microorganisms survival, reproduction and digestive activities.

Sheep can eat a large amount of forage in a short period of time, which is softened, mixed and fermented by the rumen, and then ruminated. First, regurgitate 1 bolus in the mouth, chew 70-80 times and then swallow it, and so on one by one. The number of regurgitating boluses per day is about 500, and under normal circumstances, the first rumination cycle occurs 40-70 minutes after ingestion.

Rumination refers to the return of semi-digested food in the stomach to the mouth after a period of eating, ruminant animals.

It is an animal that has this way of digestion.

Usually some herbivores.

Because plant fiber is more difficult to digest. Ruminants generally eat in a hurry, especially roughage, most of which are swallowed into the rumen without sufficient chewing, and after a period of soaking and softening in the rumen, the food returns to the mouth through regurgitation, and after chewing, it is mixed with saliva again and swallowed into the rumen again.

Feeding of ruminants:

In ruminants, they do not directly digest and absorb the nutrients in the feed through their own digestion and absorption, no matter what kind of nutrients must first be fermented by rumen microorganisms, and the organic acids and some primary fatty acids eventually produced during the fermentation process can be absorbed by the rumen as their metabolic energy, while other nutrients are digested by rumen microorganisms.

It can be said that rumen microorganisms are bacterial proteins, sugars, and lipids.

It is the most important, the most direct, and the most efficient nutrition for ruminants.

Therefore, in the feeding of ruminants, we must pay attention to the nutritional needs of rumen microorganisms to fully meet the nutrition and mineral elements of microbial reproduction.

The proliferation of rumen microorganisms can convert more non-protein nitrogen into bacterial protein available to cattle and sheep, which is of great significance for improving the utilization rate of ruminant feed and improving the nutritional level.

Minerals have a dual role in the nutrition of ruminants, it is necessary not only for the maintenance of normal metabolism of animals, but also for the reproduction of rumen microorganisms. Fully meet the mineral needs of rumen microorganisms, which is essential for improving the conversion rate of feed.

has an important role.

The rumination of cattle is the result of its main diet of grass and wood fibers. The stomach of a cow is divided into four gastric chambers, which are the rumen, the reticulum, the double flap and the wrinkled stomach. The first two gastric chambers (rumen and reticulum) mix food and bile, specifically using commensal bacteria to break down cellulose into glucose.

The food is then regurgitated, chewed slowly to mix well, further broken down the fiber, then re-swallowed, passed through the rumen to the double stomach, dehydrated, then sent to the puckered stomach, and finally sent to the small intestine for absorption.

Rumination is commonly known as inverted chewing, most of the roughage eaten by cattle does not enter the rumen without sufficient chewing, and if it is not ruminated, the food is trapped in the rumen, and the gas produced by fermentation cannot be discharged, causing the rumen to expand.

Cows have four stomachs, which are the rumen, the honeycomb stomach, the double stomach and the wrinkled stomach. The food eaten by the cow goes from the rumen to the hive stomach without careful chewing, and after fermentation, it returns to the mouth and is repeatedly chewed before being sent to the third stomach, and finally to the wrinkled stomach for absorption, which is why the cow chews its mouth when it does not eat grass.

Sheep, deer, and camels also have this ability. Why do they regurgitate? This is inherited from ancient times, as it allows these animals to eat more in dangerous or foody places, and chew slowly when it is safe or when food is scarce.

Cattle and sheep do not ruminate and are called non-pouring foam, the scientific name is the anterior stomach slow, which is a disease characterized by reduced excitability and contractility of the forestomach and digestive disorders.

**: This disease is often caused by long-term feeding of inferior coarse and hard-to-digest feed, such as soybean straw, wheat straw, wheat bran, etc.; or due to long-term feeding of soft and irritating feeds such as bran, bean dregs, sugar residue, distiller's grains, etc.; Sudden change in feed feeding method and sequence, as well as giving mildew, supercooled, and moth-eaten feed; In addition, factors that are not conducive to digestive function, such as insufficient exercise, long-distance transportation, and excessive supply of concentrate feed, can cause the occurrence of this disease if they are not corrected for a long time. Other internal, external, and obstetric diseases such as rumen gas, food accumulation, and enteritis can also be secondary to the disease.

Sheep ruminant. Sheep are ruminants.

When eating food, it will be swallowed after simple chewing, and after eating, the food eaten into the stomach will be returned from the rumen, and then chewed again in the mouth, this process is the rumination of sheep. Sheep is a general term for the sheep subfamily, one of the domestic animals of humans, and the main ** of wool. Sheep is the most complex subfamily of members, and the body shape and habits of the members are quite different, and they can be divided into several different families.

Members of the subfamily Sheep mostly live in highlands and mountains, and their distribution center is the hinterland of Asia.

Ruminants: Ruminants are artiodactyls.

in one of the suborders. Rumination refers to the return of semi-digested food in the stomach to the mouth after eating for a period of time, and ruminants are animals that have this way of digestion. Usually some herbivores.

Because plant fiber is more difficult to digest. Ruminants generally eat in a hurry, especially roughage, most of which are swallowed into the rumen without sufficient chewing, and after a period of soaking and softening in the rumen, the food is re-opened and regurgitated back to the mouth, and after chewing, it is mixed with saliva again and swallowed into the rumen again.

Rumination refers to the fact that after a period of feeding, the sheep regurgitates the feed that has not been completely digested from the stomach to the mouth again, and eats it again after chewing. The rumination time of sheep is generally about 8 hours a day, and under normal circumstances, it will ruminate about 4-8 times, and each rumination will generally last about 40-70 minutes.

Rumination is a physiological instinct of sheep, because the speed of sheep feeding is relatively fast, they will eat 60-70 times per minute, and it generally only takes 2 hours to eat. During the rest time after eating, the sheep will turn the eaten forage up from the rumen and continue to chew, and swallow it again after fully stirring with saliva to play a role in rapid digestion.

Second, what is going on with sheep spitting grass when they ruminate.

Sheep in rumination when the situation of spitting grass foam is a normal physiological boring habit, the body of the more healthy sheep will generally start to ruminate about 30 minutes after feeding, if the sheep appear diseased, there will be a reduction in the number of ruminants or stop rumination.

If the sheep ruminates when the grass is spitting, it is generally caused by older age or gastrointestinal environmental diseases, and if the adult healthy sheep have a wind chill when grazing, or when feeding, there will be a ruminant foam when spitting grass foam.

Be. It has a strong ability to digest and utilize feed. Sheep are ruminants and have four stomach chambers, called compound stomachs.

The sheep's stomach has a strong digestion ability of crude fiber, generally can digest 50%-80% of the forage, the sheep's intestine is very long, about 20 times the body length, so that the food through the digestive tract for a long time, improve the sheep's ability to absorb nutrients.

Cow rumination refers to the return of semi-digested food from the stomach to the mouth after a period of time after the cow has eaten and chewed again.

Ruminants generally eat in a hurry, especially roughage, most of which are swallowed into the rumen without sufficient chewing, and after a period of rumen soaking and softening, the food returns to the mouth through regurgitation, and after chewing, it is mixed with saliva again and swallowed into the rumen.

It can be directly regurgitated from the rumen to the mouth, or it can enter the reticulum from the rumen one after another, and then return from the reticulum back to the mouth, and then swallow back to the rumen after the fine chewing of the cheek teeth in the mouth.

It is the cow that eats the half-digested food from the stomach and returns it to the mouth after a period of time to chew it again.

It is when the cow eats the grass into its stomach, half of it is stored, and half of it is chewed twice.

Refers to cattle. Eat the food over 30-60 minutes. After eating. Save the first one, and eat it again suddenly.
