Important questions about calving cows. Why the cow does not get up for a long time, and what to do Why the cow lies down during the rain

Sometimes, due to a long and difficult birth, when the cow calves too slowly, subsequent complications occur. The animal tries to get up, but it fails. Complex calving, which is caused by different circumstances, affects the pelvic bones and the nerve endings that are responsible for the movements of the hind limbs. If you do not take care of the condition of the calving representative of the herd, then you will have to cull it later.

The cow gives birth to a calf lying on her side, but if she does not get up after that, you need to call the veterinarian

The essence of the disorder

The nerves of the gluteal region are responsible for the muscles of the buttocks, and the lumbosacral, which are located on the sides of the small pelvic cavity, for the femoral muscles. These nerve endings are characterized by vulnerability and more often than others are damaged. Then the animal does not stand up on its hind legs.

Complications after childbirth are more likely to affect the nerves of the lumbosacral region. Sometimes one side is damaged more than the other. Farmers determine this by the side on which the animal lies. Sometimes, after a difficult calving, only one leg suffers. In this case, the animal rises, but then falls. If both limbs are affected, then the sick specimen does not get up. The damaged gluteal nerve also prevents her from getting up.

Causes

This disorder occurs due to the too large size of the newborn calf. However, even with a normal fetus, damage to the nerve endings is possible if the woman in labor has:

• narrow pelvic bones;
• first birth.

Calving occurs at the end of winter, and the refusal of the woman in labor to rise is also associated with the depletion of vitamin reserves in the body. Other external criteria that cause this disease are: lack of exercise, lack of living space, injuries in pregnant women.

Especially often the cow cannot stand up after the first birth

Other reasons

In addition to nervous paralysis of the gluteal and lumbosacral endings, the fact that a cow lies down after a difficult birth is explained by the following diseases:

• Milk fever, when diseased specimens lie, they are characterized by apathy and lethargy. Pulse and temperature drop. Signs appear within two days after calving.
• Metritis, which occurs as a complication after a difficult birth or with the remaining placenta. Symptoms do not become noticeable immediately. Then the temperature rises or falls, the heartbeat quickens, the rhythm of breathing accelerates. Accompanied by indigestion, loss of appetite and refusal of water.
• Mastitis is an infectious infection of the mammary gland in violation of the conditions of care and feeding. If the disease spreads through the udder, then fever, lethargy, refusal to eat begins.
• Postpartum paresis: the cause of the appearance is an unbalanced diet and improper care, changes in the composition of the blood. The cornea of ​​the eye becomes cloudy, dries. The neck is bent. It is also possible with a fast hotel.
• Hypophosphatemia, which is caused by a lack of phosphorus in the body. Milk productivity decreases, the livestock moves with difficulty, weakens and lies down.

Actions

Beginning breeders are wondering: what to do in such a situation? It is important to make the animal stand up quickly. That's what healing depends on. If you leave the woman in labor to lie after calving, this will lead to progressive paralysis. The prognosis is also unfavorable if the animal has been in the wrong position for a long time.

It is best if the birth of a cow is taken by an experienced veterinarian.

The first action a breeder takes is to contact a veterinarian who treats cattle. A professional will determine what the matter is - in paralysis of nerve endings or a fracture (dislocation). A broken femur or a dislocated hip joint will lead to sad consequences if you try to help the animal yourself.

Fragments of bone would rupture an artery in the thigh, and the specimen would bleed to death.

If during strong attempts there is a violation of blood circulation in the sacrum, then this leads to damage in this area. Another reason why cattle do not get up is milk fever, for which a separate course of treatment is prescribed.

How to get up

If the animal does not get up after childbirth due to nervous paralysis, then the owner's task is to put him on his feet, even if he is very tired and tries to lie down. Make sure the calf is out of the way before taking active steps. Otherwise, the mother will fall on him. For the procedure, several people will be needed (at the tail and at the head) to insure against falling.

After calving, it is very important to get the cow to stand up.

Farmers are advised to perform the following actions if the uterus does not rise:

• Twist the tail: intercept it in the middle and fold gently without causing pain. Hold in this state for 10-20 seconds until the cow rises.
• Create sound effects: loud claps, screams, stomping, the purpose of which is to frighten the cow and make it rise. They do not have a significant effect on less shy specimens.
• Slightly choke: looks cruel, but in most cases causes a lying member of the herd to rise. To do this, close her mouth and nose for 10-20 seconds, blocking the access of air.
• Shock: An even more brutal method that is not recommended, however, touching the undertail area with an electric prod will cause the sick cow to stand up.

Lifting aids

If after such activities the cow gets up or tries to do it, hold her by the tail, helping not to fall. A fall is fraught with dislocations or fractures of the limbs. Keep the animal on its feet for as long as possible. The longer it stays, the better the prognosis. If again there is a fall on the hind limbs, then it is necessary to take rest breaks.

In the event that the uterus rises and stays for a long time after the impact, make sure that it is safe to leave it with the newborn. This is determined by the functioning of the hind limbs. If the cow turns around and does not fall, confidently steps over and rearranges her hooves, then leave her with the cub.

A cow can only be left with a calf if she is firmly on her feet.

If you can't get up

If the cow does not get up after the measures taken, proceed as follows:

• help her get into a comfortable position;
• if the cub is alive, feed it milk from a bottle or bring it to the nipples and hold it while it eats;
• if the uterus is in the stall, then take away the calf and bring it in after a period of time for feeding;
• in the case when the cow tries to stand up on her own, tie her hind limbs: this will help to avoid fractures, dislocations and muscle tears;
• observe sanitary conditions during maintenance (clean flooring, prevention of dampness) and a balanced diet.

The diseased specimen is periodically turned over to avoid progressive paralysis, muscle hardening and bedsores.

If human strength is not enough to support the uterus, then use the wide belt system as a suspension structure.

Wrap them around the torso behind the elbow joints of the front legs and in the back.

Various models of lifts are also used for this purpose. This is a device that clamps and lifts the pelvic part of the body. Turn the sick uterus 2-3 times a day.

The lift will help if the cow could not be immediately put on its feet

Medicines

If after calving the animal lies due to nerve paralysis, then veterinarians prescribe drugs with an anti-inflammatory effect. Heal damaged endings and reduce swelling medications with vitamin E, selenium and steroid drugs.

With postpartum paresis, caffeine benzoate, the drug "Vitam" is injected subcutaneously. Fighting this disease, the owners also resort to the method of pumping air into the mammary gland (which is not always approved by veterinarians). Hypophosphatemia is treated with intravenous injections of ursolite (500 ml per 500 kg of live weight), calcium hypophosphite solution (30 g per liter of distilled water).

Treatment is accompanied by a balanced diet, which consists of high-quality feed (grain, hay, concentrates). Add malt, oat sprouts (100 g 2 times a day), fish oil. Salts of calcium and phosphorus help. Additionally, vitamin complexes and glucose are given. To restore blood circulation, the diseased uterus is massaged, rubbed with a straw tourniquet (at the base of the legs and sacral region).

Malt and germinated grain will help the cow recover faster

1. carefully monitor the health of livestock when calving is over;
2. do not self-medicate, contact your veterinarian and follow these instructions;
3. observe safety measures when working with livestock.

The calving process in a cow can be long and with complications caused by the physiological characteristics of a large cattle. In time, the disease noticed and the medical assistance provided in most cases lead to healing from the negative consequences of childbirth.

Wintering of farm animals (cows, sheep, goats) is always a real test for owners. In the most severe winter colds, baby calves are born in the barn. And all livestock breeders are very worried about how to survive the most difficult month. Feeding and keeping a cow two weeks before giving birth always causes a lot of controversy. Someone puts the cow on a starvation diet in order to save her from possible complications during childbirth, while others continue to feed the animal with high-calorie feed. It is also not easy to make sure that the cow calves without complications and fully restores her strength in the postpartum period. So our conversation today is about how to help a cow during the most crucial 4-5 weeks for her in order to maintain her health and high milk production.

By calving, the cow must have good fatness. Otherwise, after childbirth, even with abundant feeding, good milk yields cannot be expected from her. It is necessary to feed in such a way that during the period from launch to calving, the live weight increases by 10-12%, that is, the average daily weight gain is normal - 800-900 g. But more feed should be put in the feeders not in the last months before childbirth, but throughout second half of pregnancy. Then in the last month before calving, the feeding of the animal can be moderate. This will favorably affect the normalization of metabolism in the prenatal and postnatal periods.

The main thing in the prenatal period is an individual approach to the cow. Usually, 7-10 days before calving, succulent foods are excluded from the diet or their supply is reduced. This primarily applies to the silo. 2-3 days before the birth, the giving of concentrates is stopped. At this time, it is obligatory to give good-quality hay (according to palatability) and talkers from laxative concentrates (wheat bran, oatmeal).

In cases where the cow is well fed before calving, her udder is in a normal state, then it is not necessary to exclude the usual animal feed from the diet. It should be remembered that significant changes in the composition of the diet before calving are undesirable, as they lead to a change in digestion in the rumen and adversely affect the metabolism in the body.

The best feed for pregnant cows in the prenatal period is cereal-bean hay, haylage, silage, fodder beets and mixed fodder. Hay can be fed ad libitum, haylage is given at 6-7 kg, silage - at 10-12 kg, fodder beet at 4-5 kg ​​per head per day. In order for cows to receive a sufficient amount of carotene, give them 0.5-1 kg of carrots. All food for the expectant mother should be of high quality, clean, mold free. You need to feed and water the cow 2-3 times a day. The temperature of drinking water must be at least 10°C.

AT winter period a pregnant cow should walk at least 2-3 hours a day. But at air temperatures below minus 20 ° C, walks should be canceled. Also, in severe bad weather, it is better for the animal to stay indoors.

In the last 2 weeks of the prenatal period, it is necessary to carefully observe the behavior of the cow. The approach of calving is judged by a number of signs. 2-3 weeks before calving, the cow's udder noticeably increases, and the stomach is pulled down. 5-10 days before delivery, the ligaments in the pelvis and tail root relax, become soft, the external genitalia swell, a secret is milked from the udder, resembling sugar syrup in appearance. As the birth approaches, it becomes more milky, colostrums appear in it. The formation of colostrum is a sure sign of approaching childbirth. 12-20 hours before calving, it rushes to the nipples, transparent mucus is released from the vagina. The cow often lies down and gets up, steps over with its hind legs, mooing, feces and urine are involuntarily excreted.

Then labor pains begin, which are periodically repeated. At this time, it is necessary to replace the contaminated litter in the stall, the back of the body and the external genital organs of the cow are washed with warm water and soap and irrigated with a weak solution of disinfectants, the most accessible of which is potassium permanganate.

The course of calving must be closely monitored in order to provide, if necessary, help you need. In healthy, well-prepared cows for calving, childbirth takes place without outside interference and lasts from 20 minutes to 4 hours.

30-50 minutes after calving, the cow is fed with warm salted water (one handful of salt per bucket of water). About the same time after birth, the baby rises to his feet, he has a sucking reflex. Therefore, the udder of the animal must be washed with warm water, wiped dry with a clean towel, milked the first streams of colostrum in a separate bowl and slip the calf to the mother's udder. The cow is kept together with the baby for the first 3-5 days, then they are separated.

The first 2-3 weeks after calving are also a very responsible period for caring for a cow. At first (the first 2 days), the cow should be fed moderately, given benign, easily digestible food (good hay, fodder beets, concentrates, etc.). Heavy feeding using large concentrates at this time can cause indigestion and even inflammation of the udder. By the end of the first week, the dacha of concentrates, beets and silage is gradually brought to normal.

In the first days after calving, the udder of the animal is edematous, maloelastic and hard, therefore, during milking, all the milk must be given out and the udder massaged. If these requirements are met and the cow is properly fed, udder edema decreases after 4-5 days, and completely disappears after 7-10 days.

Already on the 4-5th day after the birth, the cow can be let out for a walk in the walking yard for 2 hours. The animal can then stay in the yard even longer.

If the calving of the cow was normal and there are no postpartum complications, then it can be inseminated already in the first hunt, that is, after 18-24 days. When purulent discharge with an admixture of blood appears from the vagina, the first hunt should be skipped, and insemination should be carried out in the second hunt.

Approximately from the second decade after calving, as soon as the udder returns to normal, they begin to distribute the animal in order to achieve the greatest productivity from it during lactation. At this time, they continue to carefully care for the udder and every ten days (every 10 days) add 1 kg of feed and 4-5 kg ​​of fodder beets to the main diet. Feed is added as long as milk yield increases. If the cow does not respond to an increase in the feeder with an increase in milk, there is no need to give extra feed. The milking process itself lasts the first 2-3 months of lactation.

In the most difficult period, your nurse will need a lot of attention and care, but for all the trouble she will reward you a hundredfold with an abundance of dairy products on the table.

Thus, let's sum up

Signs of approaching calving

Of course, you can find out about the approximate time of a cow's calving by calculating the period of her pregnancy on a calendar (for cows, it is 270-300 days). The last two weeks before the approximate date, the cow should be closely monitored. The approach of calving can be judged by a number of signs:

2-3 weeks before calving, the udder noticeably increases, and the stomach is pulled down.

5-10 days before calving, the ligaments in the pelvis and tail root relax, become soft, the external genitalia swell, a secret is milked from the udder, which looks like sugar syrup. The closer the birth, the more this secret resembles milk - it becomes more white and "milky".

1-2 weeks before calving, the cow's udder noticeably enlarges, the ligaments of the pelvis relax, which is noticeable in the recesses from the side of the tail root, the vulva swells.

12-20 hours before calving, colostrum flows to the nipples of the udder, transparent mucus is released from the vagina. The cow shows signs of anxiety, becomes shy.

cow in front of calving

The first stage of calving is the preparatory period. The animal becomes restless, steps over its feet, often lies down, gets up, looks at the stomach. There are frequent excretions of feces and urine. This period can last from 3 to 8 hours.

Until the fetus begins to come out, you can prepare the calving place: change the bedding to a clean one, wash and disinfect the place of the future calving. The external genital organs of the cow, tail and udder must be treated with a warm solution of potassium permanganate (1:1000) or warm water.

Precautions during calving

It is best that the calving take place under the supervision of a qualified specialist who can provide the necessary assistance to the woman in labor and the newborn calf;

In the room where the hotel takes place, silence should be observed. Cows, especially heifers, are very sensitive to human presence;

Even if you think it's time to intervene, don't panic. Normal childbirth lasts 25-30 minutes, and too early intervention in the birth process, when the legs and head of the calf have not yet advanced to the outer part of the vagina, can disrupt its course;

Remember that only clean hands should help at the hotel!

You can not push the labia with your hands, as this can lead to a rupture of the perineum;

After the birth of a calf, the umbilical cord usually breaks. If this does not happen, it is necessary to tie the umbilical cord at a distance of 8-10 cm from the abdominal wall of the fetus, and then cut it with scissors 1 cm below the ligation. Disinfect the end with tincture of iodine.

Reception of a newborn calf

Prepare a soft straw bed lined with clean burlap. The calf should be placed on it, carefully removing mucus from the mouth and nostrils with clean gauze or a cotton swab. It is best to let the cow lick the calf, but if, for some reason, she does not, wipe his body with clean burlap or soft straw.

After the birth of a calf in a cow, the afterbirth should separate within 6 hours. To speed up its separation, immediately after giving birth, the cow is fed 5-8 liters of warm salted water, a bran mash and fed with hay.

The separated placenta is burned or buried, as some cows eat it, as a result of which their digestion is upset.

In winter, a newborn calf should be covered with burlap or clean straw, and in severe frost (if the temperature in the barn is 10-15 degrees), you can additionally cover it with a blanket, and tie a towel around your head to protect your ears from frost.

After calving and separation of the placenta have passed, the external genitalia, tail and limbs of the cow should be washed with a warm 2% solution of lysol or creolin, the calving site should be cleaned and disinfected, and fresh straw bedding should be placed.

cow after calving

After the newborn calf stands up, it has a sucking reflex. Up to this point, it is necessary to wash the cow's udder with warm water, wipe dry with a clean towel and milk the first streams of colostrum in a separate bowl. After that, the calf can be slipped to the mother.

The first 2-3 weeks after childbirth is a critical period. Young mothers, especially first-calf heifers, are in a state of extreme stress, so it is especially important to take care of their condition and do everything so that the animals return to normal as quickly as possible.

The first 2 days the cow should be fed moderately. Give her easily digestible good quality food (too much feeding during this period can cause indigestion and even inflammation of the udder). By the end of the first week, the dacha of concentrates, beets and silage is gradually brought to normal.

In the first days after calving, the cow's udder is hard and swollen, so be sure to massage the udder and milk all the milk. If these requirements are met and the cow is properly fed, udder edema decreases after 4-5 days, and completely disappears after 7-10 days.

On the 4-5th day after calving, the cow can be let out for a short walk (about 2 hours), later, the walk time can be gradually increased.

Feeding newborn calves

The calf should receive the first portion of mother's colostrum no later than one hour after birth. This activates the digestive system of the newborn: the functions of the stomach and intestines return to normal, the original feces are released and the intestines are populated with microflora. But if the first feeding of colostrum is late, the calf may begin to have problems with digestion.

The first 4-5 days after birth, calves are given colostrum four times a day, drinking 1.5-2 liters at a time. The intervals between drinking should be equal. If the calf is kept with its mother, the cow must be milked after each feeding, since the calf usually cannot suck out all the colostrum completely.

Starting from day 5, calves should be given boiled salted water for colostrum. Before drinking colostrum, and then 30-60 minutes after it.

From the 6-7th day, the calf is transferred to three meals a day.

Starting from 15-20 days from birth, healthy calves can be given dietary supplements (bran, grated carrots) and high-quality hay and let them go for walks on warm days.

The cow fell to her feet, 6 months pregnant. 3 days pierced calcium gluconate with glucose. On the 3rd day they injected glucose with calfased. The cow seemed to stand up. That was enough to get her into the barn and have her eat. In the morning I got up with difficulty, ate and lay all day, though I changed positions. In the evening they raised it again with difficulty. Ate and fell. How long can this state last? Will it affect pregnancy? (Olga)

Olga, your situation is quite common, however, most often farmers are faced with a fall on their feet in cows after childbirth. This is the so-called birth paresis. But it also happens before calving, as in your case, which is referred to as fallow. The exact cause is still not known even by the veterinarians themselves.

Most often this is due to a lack of nutrients, a change in the composition of the blood due to pregnancy, the accumulation of fluid in the soft tissues of the hind limbs due to uterine pressure. And also with poor exercise and cow walking, impaired blood flow in the back of the body. For example, the latter happens if the cow is kept in a narrow pen with a sloping floor. In general, now our task is not to find out the cause, but to quickly help the animal get back on its feet. Since its prolonged lying can lead to the biggest problem - bedsores.

What to do?

First, you need to start massaging the back of the cow right away to minimize blood stasis and the formation of pressure sores. You need to use fists, but not with pressing movements, with light rotational massages of the sacrum area. You need to continue to try to raise the animal to its feet, or at least turn the cow from side to side, make a softer bedding.

If there is still a lot before the birth, then our task is, firstly, to prevent the intestinal stoppage, and secondly, to prevent bedsores. At this time, you need to inject drugs that stimulate the intestines. What exactly should the veterinarian advise, since I myself have not encountered this.

Pay special attention to the diet, namely, to normalize the amount of protein feed due to concentrates. Include sprouted grains in the regular menu, for example, sprouted oats 50-100 grams 2 times a day. Give injections of vitamins A and E, calcium and phosphorus. To get the animal to its feet faster, a cycle of special maintenance injections will be required. The same glucose will do, plus you can still use the Tetravit (Trivit) complex, 5 ml once a week.

It is impossible to say how long this will take, it happens that cows get up only after giving birth. But with improper care, there are also deaths or the development of postpartum paresis.

Incredible Facts

Now it is simply accepted as a proven fact that swimming immediately after a meal will cause you to have a sudden cramp that will drag you to the bottom. Moreover, everyone knows that if you watch TV too close, you can destroy your eyesight.

Being pure superstition, these tales are passed down from generation to generation, told to family members and friends, in such a way that they take root in such a way that they do not even give in to doubt. These legends, which often concern health and nutrition, range from completely absurd to partially plausible. Below are 9 grandma's tales and the truth behind them.

1. If you start swimming without waiting one hour after eating, you may have a cramp and you may drown

Most children have probably heard from their parents that they should wait at least an hour after eating and then jump into the water. Otherwise, they may drown. In fact, there is something plausible in this, because in this case, a change in the blood flow in the body is involved.

When you eat something, your body increases blood flow to your abdominal muscles to help with the digestion process. The more food you eat, the more oxygenated blood goes to your stomach muscles for digestion. But this means that it will become less in the blood circulating in the limbs that are actively working during exercise (whether it be running, swimming, cycling or something else). Depriving the muscles of the arms and legs of oxygen can presumably lead to seizures, presumably increasing the risk of drowning.

For recreational swimmers, the risk of cramping after eating is actually very low, because there is enough oxygen in the body, which is enough for both the abdominal muscles and the limbs. The real danger lies in those who eat a hearty meal before a session of vigorous swimming. Indeed, in such cases, convulsions and even vomiting may occur. But, nevertheless, all doctors unanimously say that this is unlikely to lead to drowning if the swimmer does not start to panic and forget how to swim.

2. Cows lie down on the ground on the eve of rain

How accurately can rain be predicted? Just visit the cow pasture. If all the cows are on the ground, it will soon rain. At least there is such a sign.

Some proponents of this prejudice have taken it upon themselves to figure out why our four-legged friends lie down in anticipation of rainfall, and many of these theories sound pretty plausible. The simplest explanation is that the cows simply sense the increase in humidity and lie down to keep some of the grass dry.

Another theory is that cows do this to relieve their stomachs, which are supposedly sensitive to changes in barometric pressure caused by rain.

The most complex of the theories is that cow limbs have a microporous structure that quickly absorbs moisture. When the air fills with moisture as rain approaches, the cow's limbs absorb more and more of it until they become quite soft and can no longer support the weight of the animal.

However, is there any truth in all these explanations? Unlikely, because cows lie down on the ground for many reasons, and there is no scientific evidence that rain is one of them. As the farmer's almanac says: "If a cow is lying in the field, then this most often means that she simply decided to chew lying down, and is not waiting for rain." Indeed, if weather forecasts were made based on the behavior of cows, they would always be very gloomy.

3. Cats kill their babies by literally sucking the life out of them.

There are several prejudices associated with cats. Perhaps the most common of these is that black cats bring bad luck. This is immediately followed by the popular belief that cats suck out the breath of their kittens, which ultimately kills them.

There are two prevailing ideas that may explain why your cat will want to stifle the joy that comes into your home: the first is that cats love milk and love the milky breath of their babies; the second is based on alleged feline jealousy, when all your attention is switched from them to their babies.

Experts highly doubt that cats purposefully suffocate their kittens, most often this happens accidentally during sleep or play. But how did this myth become so popular?

4. Spicy food contributes to the appearance of ulcers

For decades, doctors believed that eating too much spicy food could cause stomach ulcers, or painful ulcers in the lining of the esophagus, stomach, or upper small intestine. This, of course, made sense, because patients often complained of a burning sensation in the stomach after eating spicy food. At the same time, they were prescribed as a treatment to simply switch to soft foods, which did not really get rid of the ulcer pain.

But in the 1980s, scientists finally dispelled this myth, at least in scientific circles, because many people still believe it. Studies have shown that spicy foods do not contribute to the appearance of ulcers, it can only irritate existing ones, most likely because of this, this misunderstanding has arisen.

The real culprit in most ulcers is the bacterium Helicobacter pylori. When it enters the body, the bacterium immediately travels to the stomach, releasing protective enzymes to protect itself from digestive gastric juices. Getting into the mucous membrane of the stomach, which partially protects it from the ingress of white blood cells, which are the main weapon of the immune system against bacteria. After the bacterium colonizes the stomach, an ulcer develops.

Today, treatment for peptic ulcers consists of taking antibiotics to kill the infection, however, recent studies have shown that cranberry juice is also effective in this process. Interestingly, cranberry juice has long been part of another, possibly correct, speculation that it is effective in fighting bladder infections.

The mechanism behind the work of cranberry juice in both cases is the same: the compounds contained in cranberry juice prevent bacteria from attaching to the cells that make up the urinary tract, and also protect the stomach lining from them.

5. Putting soap under the sheets can help you get rid of leg cramps.

As strange as this "fairy tale" may sound, there is a large amount of anecdotal evidence to support this. Many people post this recipe on internet health forums and say that this home remedy can really help people get rid of nighttime leg cramps. However, there are no scientific studies to support the effectiveness of this "treatment".

Similar anecdotal evidence also exists for the prevention of restless leg syndrome, but on a smaller scale. Only in this case it is recommended to use lavender soap. Experts say that the smell of lavender is relaxing on its own and can be helpful in this condition. However, there are no peer-reviewed studies in which lavender or lavender soap can be used to treat restless leg syndrome.

So if you're worried about night cramps, you might still try this method, even though there's no evidence that these treatments work. What are you losing? Only, as the online supporters of this method write, do not use Dove soap, you will not succeed with it. Why? Your answer to this question will be as good as any other.

6. After shaving, new hair grows thick and coarse.

When you shave your legs, underarms, or any other part of your body, you may find that the new hair grows back thick and coarse. But this is not really the case.

The hair tapers at the end, so we see the thinnest part of it. When we run a razor over them, we "cut off" the thin part of the hair, and leave the thick part to grow. It looks like each individual "strand" takes up a little more space.

Also, the hair feels rough to the touch because it has become shorter and has been "cut" straight across. Even the apparent darkening of the hair is an illusion, as it appears darker due to the fact that you are now seeing dots directly on your normal skin color.

Scientists even conducted a study in which they tried to find out if shaving affects hair growth. In 1982, a study published in the journal Anatomical Record and conducted by forensic anthropologist Mildred Trotter concluded that shaving does not affect hair growth rate, color, structure, or texture. Recent studies have come to similar conclusions.

7. Had a baby, lost a tooth

The well-known statement says that with every child born, a woman loses one tooth, mainly due to hormonal changes that occur during pregnancy, which affect oral health. While there is no real correlation between the number of children a woman has and the number of teeth she loses, experts have indeed found a link between pregnancy and certain dental problems.

In 2005, a study of more than 2,500 pregnant women, conducted by experts from the College of Dentistry at New York University, showed that women do not lose teeth with each new child, but the chances of losing them increase. Also, more and more children are at risk of developing periodontal disease.

There are several reasons that can affect the oral health of a pregnant woman. Among them are morning sickness (vomiting destroys tooth enamel), dry mouth due to hormonal changes (less saliva increases the risk of cavities), an increased desire to eat sugary foods and starchy foods (which can damage teeth). In addition, studies have shown that pregnant women rarely visit the dentist.

However, this problem is not new. In 2008, scientists found that since the rise Agriculture about 10,000 years ago and the human population boom began, women's oral health was worse than that of men. Have a baby, lose a tooth? Probably not. Have a baby, get dental problems? Maybe.

8. Chocolate makes acne worse.

Although chocolate may be best friend your taste buds, it is your skin's worst enemy. Something like this sounds like another prejudice. But is there any evidence that chocolate is somehow linked to the "production" of acne?

Back in 1969, the first study on the subject concluded that there was no link between chocolate consumption and acne, and later other studies only confirmed these findings. Moreover, more recently conducted experiments have come to exactly the same results. In general, experts say your diet has little effect on acne.

However, several recent studies have cast doubt on this claim, as some link has been found between pure chocolate and acne formation. Thus, the new data divided the experts into two groups. As expected, all as one argue that there is a need for more experiments.

9. Sitting too close to the TV is dangerous for your eyesight.

"Don't sit too close to the TV, you'll ruin your eyesight!" - almost everyone heard this phrase from their worried parents. Once it was true.

In fact, all televisions produced since the middle of the last century have had very high level radiation that increased a person's risk of developing vision problems as a result of repeated and prolonged exposure.

But now this problem is in the past, because modern TVs are equipped with proper protection that blocks radiation. At present, TV can only provoke eye fatigue and excessive eye strain, which can be easily cured by simple rest (the same goes for the myth of reading in dim light).

Cows are herd animals and this is confirmed if you observe a group of animals grazing on a pasture. In the pasture, cows show their natural behavior most naturally. If it were possible to transfer such behavior indoors, then this would mean better comfort.

Cows lie down for up to 14 hours a day if the rest box provides the necessary comfortable conditions If the cow

forced to lie down on a concrete floor or hard rubber mats, then the duration of lying down can be reduced to 6 hours. It can be said that standing cows are less productive than lying down. Reduced lying down slows down productivity.

Many factors contribute to productivity in normally resting (lying) cows:
more intense salivation. High salivation regulates the pH in the rumen and allows efficient use of energy-rich diets. A stable pH value in the rumen prevents acidosis and laminitis (acute inflammation of the sole of the hoof) that often develops in highly productive cows;
higher blood circulation in the udder, which contributes to an increase in milk synthesis (by 8%). British researchers have shown that in lying cows the blood circulation in the udder is 1 l / min more than in standing animals, unloading of joints and hooves from the pressure of body weight. If the cow lies in a dry box, then the hooves dry well and the hoof horn becomes harder and more durable.

Whether cows rest enough can be judged by their behavior:
the duration of rest is desirable at least 80% of the daily time. This can be determined by timing the method of random sampling; it is enough to select 10 animals for this;
if a cow is looking for her rest box, it means she wants to lie down. 85% of cows lie down 5 minutes after they enter the box;
pay attention to the condition of the joints of the limbs and hooves. In no more than 5% of cows, swollen or skinned hocks can be seen. This is a result of the fact that when cows lie down on a hard floor, they kind of fall to their knees from a height of 20 cm. And this knee test shows whether the floor in the box is soft enough to rest. In boxing, cows should rest calmly, squatting without frequent stretching of the fore and hind limbs;
the very nature of the cow's lying is also evaluated. If her pelvis is on the edge of the box, then this means that the box is shorter than 170 cm or there is no space necessary for the position of the head;
if many cows are standing in the box with their heads down, their necks hit the upper crossbar (limiter) or the hind limbs are outside the area of ​​the box, then this means that the bar is too far back and needs to be moved forward.

When building a cow rest box, 4 factors are important.
1. Space for the location of the head. When standing up, the cow moves forward and this requires a space of 80 - 100 cm. This means that in front of the platform on which the cow lies (170 cm), there should be at least 80 cm no obstacles, for example, fencing pipes or partition elements that interfere with the cow when getting up. 80 cm of free space both horizontally and vertically guarantees sufficient space for the head and therefore for swing when standing up.
2. The upper crossbar of the feeder. She only then restrains the cow when moving forward, when she stands in the box with all four legs. The top bar should be exactly above the shoulder blades.
3. Floor in boxes for rest. Cows like to lie on a dry, soft, well-ventilated surface. The softer the floor, the longer the cow lies. Many farms in Western Europe use sand bedding (layer thickness of at least 15 cm), straw cutting and sawdust
Keeping cows on litter is somewhat labor intensive and relevant organization manure removal, but with careful care, cows prefer this method of keeping. Rubber mats are widely used, they provide a fairly soft place to rest without much labor. To bind moisture, mats are also recommended to be covered with bedding. Regardless of the type and number of boxes, they must be cleaned at least twice a day to keep them clean and dry.
