What are the causes of diarrhea in piglets? How to solve it quickly and efficiently?

In the context of the gradually cold weather, many users have said that the number of piglet diarrhea has increased, but in fact, this cannot be blamed entirely on the climate, because the cause of piglet diarrhea is very complex. Let's take a look at the causes of diarrhea in piglets and the corresponding coping methods.

First of all, let's talk about the weather, which is certainly an important aspect of diarrhea in piglets. Because piglets, especially lactating piglets, are very sensitive to changes in temperature, if they are attacked by cold air during this period or the insulation of the farm is not done properly, it is easy to cause diarrhea in piglets. Weather factors can also be classified as stress factors, in addition to the separation of mother and piglets, piglet grouping, feed changes, etc., all have the possibility of causing stress diarrhea in piglets.

In addition to diarrhea in piglets caused by stress factors, maternal diarrhea in lactating piglets is also a common cause of diarrhea. And there are two different situations:

One is more common, such as inflammation or certain diseases in the sow itself, which causes the sow's milk itself to be poisonous, which leads to diarrhea in piglets. Or the sow itself suffers from laclactia, resulting in piglets not getting enough breast milk, lack of maternal antibody protection and are prone to diarrhea.

The second is a less common situation, if the sow is not properly cared for during pregnancy and malnutrition, it will affect the normal development of the fetus in the womb. Such piglets are also prone to diarrhea after birth. In addition to nutritional factors, pregnant sows will also affect the normal development of piglets if they are constipated or abuse of mold removers, which should also be noted.

In addition to the effects of low temperature, weaned piglets may also cause diarrhea due to the lack of some essential nutrients in the feed. I will not talk about the extremely bad behavior of feeding moldy feed, the pH of the feed is unreasonable, and the lack of necessary trace elements (such as iron, zinc, etc.) will also lead to diarrhea in piglets.

Of course, none of the above factors are the main factors that cause diarrhea in piglets, and the most important factor is the disease related to diarrhea caused by some pathogenic microorganisms. Typical examples include infectious gastroenteritis, epidemic diarrhea, piglet yellow dysentery, etc. Less typical are diarrhea caused by rotavirus and diarrhea caused by parasitic diseases.

If you want to completely eliminate piglet diarrhea, prevention is far more important than **. How to do a good job of prevention, it is necessary to refer to the factors listed above that may cause diarrhea in piglets. For example, you do a good job of sanitation on the pig farm and disinfect it regularly to reduce the chance of piglets coming into contact with pathogenic microorganisms.

Secondly, the health care of sows should be done well, which is not only for the health of sows, but also for the normal growth and development of piglets. Of course, some special drugs for dealing with diarrheal diseases in pig farms also need to be read, such as gentamicin, enrofloxacin, etc., which will not be repeated here.

There are three causes, the first is due to lack of nutrients, the second is due to bacterial diarrhea, and the third is viral diarrhea. At this time, these piglets can be supplemented with some antibiotics, or the piglets can be given some more protein-rich feed.

The main causes of diarrhea in piglets are: poor milk quality in sows, too thick or too thin, or bacterial bacteria in the milk after infection. Escherichia coli and salmonella can cause diarrhea in piglets, antibiotics can be used**.

Rotavirus and coronavirus can cause diarrhea, but antibiotics can only prevent secondary infections if there are no effective drugs**. These piglets can be supplemented with some antibiotics or given some protein-rich feed.

The main causes of diarrhea in piglets are as follows: The sow's milk is not of good quality, too thick or too thin, or infected milk carries bacteria. Escherichia coli, salmonella, etc. can cause diarrhea in piglets, and antibiotics can be used**.

Rotavirus and coronavirus can cause diarrhea, but there are no effective drugs** and antibiotics can only prevent secondary infection. Plant-based feed, if it contains soybean meal, can sensitize the piglet's intestines, so suckling pig feed should contain high-quality protein raw materials in addition to soybean meal. In addition, piglets should be fed as early as possible to allow their digestive tract to adapt to changes in plant-based feeds.

Poor hygienic conditions in the farrowing house, humidity, large temperature changes, and poor environmental conditions can also cause diarrhea in piglets. The sow should be given some antibiotics before giving birth, which can enhance the immunity of the piglets, and the jaundaria in piglets is mainly caused by E. coli.

The causes of diarrhea in piglets are generally divided into infectious diarrhea and non-infectious diarrhea, and if further subdivided, infectious diarrhea can be divided into viral diarrhea and bacterial diarrhea; Non-communicable diarrhea can be subdivided into antigenic allergic diarrhea, stress diarrhea, and digestive diarrhea.

1.Infectious diarrhea. It mainly depends on strengthening the management of pig farms, drug prevention, and vaccination.

a.In terms of pig farm management, adhere to self-breeding and self-raising, do a good job of isolation and observation of introduced piglets, and attach great importance to the prenatal and postpartum feeding and management of sows.

b.Newborn piglets, pay attention to keep the pig house dry, clean and warm, and ensure that the feed and drinking water are clean. Vaccination can be given 2-3 weeks before farrowing, or preventive drugs can be added to the piglet feed to prevent diarrhea in piglets.

2.Non-infectious diarrhea. To strengthen feeding management, it is necessary to ensure the nutritional balance of pregnant sows, increase the content of immunoglobulins in sow colostrum, and enhance the resistance of piglets.

The piglet's feed should be reduced in protein content, which can reduce the piglet's indigestion. In addition, it is also necessary to avoid changing the piglet feed at will to reduce the occurrence of antigenic reactions.

At present, many pig farms and enterprises are using the problem of piglet diarrheaAgeliwithAi Ji QiangAs a new generation of auxiliary solution for diarrhea in the delivery room, the former is a compound preparation product with a variety of specific yolk antibodies, escorting the health of piglets; The latter is a combination of a variety of specific yolk antibodies, which purifies the digestive tract of sows and reduces the detoxification of sows to the farrowing room, which is a key step in solving the problem of farrowing room diarrhea

Why do your piglets keep having diarrhea? **Several major causes of diarrhea in piglets.

Piglet dysentery, mostly occurs at the age of 10-30 days, can occur all year round, but occurs more in severe winter, hot and rainy seasons; Whenever the climate suddenly deteriorates (such as heavy snow, cold snaps, etc.), the number of cases increases significantly; Poor sow feeding management and hygienic conditions, such as damp and cold pens, lack of bedding, filthy feces, and irregular temperatures; Poor feed quality, improper mixing, abrupt feed changes, lack of minerals and vitamins, over-lactation, over-concentration or under-lactation in sows can all contribute to the occurrence and severity of the disease.

Sick pigs have loose stools, gray-white or gray-yellow, fishy smell, late defecation incontinence, become emaciated and die, or become dwarf pigs. Prophylaxis.

**：1.For primiparous sows, it is recommended to use E. coli 6-valent vaccine for vaccination.

2. Early and timely**.

**There are many drugs and methods for white dysentery, which should be selected according to the place and time. Such as Bailongsan, garlic licorice liquid, honeysuckle garlic liquid, silica silver, activated charcoal, dysentery and bacteriogenesis, supplementation of ferrous sulfate or selenium, thread embedding**, etc., with astringent, antidiarrheal, digestive aid as the main drugs, if necessary, take antibacterial drugs such as dysentery.

3. Mainly take comprehensive prevention and control measures, actively improve feeding management and sanitary conditions, and do a good job of regular prevention, including: (1) strengthening the feeding management of pregnant sows and lactating sows, and appropriately supplementing the feeding or adding feed rich in minerals and vitamins; (2) Do a good job in the feeding management of piglets; (3) improve the environmental sanitation of the pig house; (4) Prophylactic administration. Sulfamidine, streptomycin, chloramphenicol and norfloxacin all have certain efficacy.

It seems like oh, I learned it in school, but I haven't been exposed to it for a long time. But hope it helps. Thank you for your advice.

Diarrhea caused by nutrition and feeding management: There are more than 10 common causes of this diarrhea, such as: insufficient milk in sows, indigestion of milk substitutes, vitamin and mineral deficiencies, excessive copper addition in piglet diets, excessive metal ions in drinking water, and stress factors such as weaning, grouping, and transfer of piglets can lead to diarrhea.

2. Bacterial diarrhea: common include yellow dysentery, red dysentery, white dysentery, paratyphoid fever and dysentery. Yellow dysentery is mainly found in piglets within a few hours to 5 days of age, with the most common disease occurring at the age of 1 3 days.

Erythrhoea mainly occurs at the age of 1 to 3 days, and the course of the disease is generally short, and the mortality rate is extremely high. Vitiligo dysentery is the most common at the age of 10 and 30 days, with a low mortality rate, but it affects growth and development. Paratyphoid fever in piglets mostly occurs at the age of 2 to 4 months.

3. Viral diarrhea: infectious gastroenteritis, epidemic diarrhea, rotavirus infection, etc. are common. Porcine infectious diarrhea is an acute infectious disease caused by infectious gastroenteritis virus, characterized by vomiting, severe diarrhea, dehydration, and high mortality of piglets within 10 days of age, with very few deaths in sick pigs over 5 weeks of age.

I hope my reply is helpful to you.

The diarrheal diseases of piglets mainly include paratyphoid fever in piglets, coliform coli in pigs, clostridial enteritis in pigs, dysentery in pigs, infectious gastroenteritis in pigs, parasitic diseases in pigs, epidemic diarrhea in pigs and rotavirus infection in piglets. Precautionary measures: Implement the "all-in, all-out" system, pregnant sows are dewormed before farrowing, and disinfection work is done at all stages.

Strengthen the feeding management of pig herds, pay attention to piglet heat preservation, piglet feed modulation. Vaccine immunization prophylaxis Porcine infectious gastroenteritis and epidemic diarrhea virus dual live vaccine or inactivated vaccine are used, and sows are immunized once each 5 weeks and 1 week before farrowing; Pregnant sows were immunized twice with Escherichia coli K88 and K P trivalent inactivated vaccines on 40 and 15 days before farrowing, and newborn piglets obtained passive immunity by eating colostrum, which could prevent yellow dysentery and white dysentery in piglets; 6 7 weeks and 3 4 weeks before farrowing, sows were immunized 2 times with Clostridium weisseri inactivated vaccines; Weaned piglets are immunized with live paratyphoid seedlings drinking water, and then boosted at 50 days of age to prevent salmonellosis in piglets.

Weaned piglet diarrhea is a common problem in pig farms, and the reasons for this are mainly due to the following aspects:

1. Blindly pursue the age of weaning, there is no teaching plan before weaning, and weaning will be done when the time comes;

Early feeding at the age of one day is only a formality, no effect, the trough is placed outside the incubator (piglets are afraid of cold and do not eat) or there is no control of the piglet feeding time (piglets with sufficient milk do not eat the feed), in fact, the early feeding is not achieved;

3. There is no early feeding plan, and the piglets are only lured after 20 days of age, regardless of whether the piglets eat feed, and weaned in 28-35 days;

4. Before weaning, the piglets that are not well induced to eat begin not to eat, and the piglets are overeaten due to hunger, and indigestion causes diarrhea;

5. After weaning, the position of the trough is insufficient, and the piglets compete for food, starvation or overeating will cause indigestion and diarrhea;

6. No heat preservation measures were taken after weaning, and environmental stress caused diarrhea;

7. Change the feed immediately after weaning.

1. Timely weaning - piglet weaning can not be based solely on time, it should be based on the piglet's feeding situation (generally 28 days of weaning requires the cumulative feed intake of piglets to reach more than 500 grams), only when the piglets can happily eat the feed can be weaned;

2. Early inducement - 7 days of age to start baiting, piglets and sows isolated, regular feeding, gradually extend the interval between feeding, forcing piglets to starve and forage, piglets that do not eat should be manually assisted (suckling pig feed with warm water and into a paste, smeared in the piglet mouth, generally after 3-5 days of training piglets can eat their own feed. ）；

3, fresh suckling pig feed - do not put the suckling pig feed in the pig house, how much to take how much, after the bag mouth is tightened, feeding should be less fed diligently;

4. Suitable slot - the feeding trough should be placed in a suitable place at a suitable temperature to prevent piglets from being afraid of cold and not eating;

5. Clean trough - suckling pig trough at least every day.

Wash it once to prevent the piglets from eating the moldy overnight trough attachment and causing diarrhea;

6. Appropriate feeding restriction - if the inducement is not good before weaning, appropriate feeding restrictions can be taken in the first 2-3 days after weaning.

It is necessary to know what causes diarrhea in piglets, and if it is diarrhea after weaning, it is a stress response to weaning. It is caused by intestinal damage caused by the intestinal inadaptability of the piglet to the feed. In this case, it is recommended to use the weaning peptide of Baineng Animal Protection, which can effectively adjust and repair the intestinal tract of piglets, so as to solve the problem of diarrhea.

If the situation is unclear, you can use the peptide Baozaikang, which has a strong anti-diarrheal effect, and it is a biological peptide technology, almost nothing.

The clinical symptoms of swine fever vary with the virulocity of the swine fever virus and the length of stay in the pig. According to the results obtained from our research on the wild poison of swine fever isolated in China using animal models, swine fever can be basically divided into three types: acute, subacute and chronic. The incubation period of the acute type is generally 24 72 hours, the initial symptoms are depression, sharp loss of appetite, to the later stage of the sick pigs anorexia, often put the mouth to the trough for a moment and then return to the resting place.

The body temperature rises, up to 41 42 or above, and it does not go away, but it is slightly lower in the morning. At the same time, the number of white blood cells decreases, and the total number of white blood cells is 9000 3000 mm3. At the beginning of the disease, the eye discharge of sick pigs increases, accompanied by conjunctivitis leading to tearing, and in severe cases, the eyelids may be completely adhered together.

Some sick pigs also excrete nasal fluid. At the beginning of the high temperature, constipation usually occurs, followed by severe yellow-brown watery diarrhea, and some even vomit yellow, bile-containing liquid. Sick pigs are afraid of the cold and often gather together, shivering, lethargic, and fluffy coats.

Sick pigs are emaciated and weak within a few days, and most pigs walk with twisted or shaky steps, and then often have paralysis of their hind limbs, unable to stand and sit in a canine sitting position. Occasionally, convulsions may be seen. There are often red or purple bleeding spots on the abdomen, ears, rhinoscopes and limbs, and even the whole body, which gradually expand into patches or bleeding spots, and even have **necrotic areas.

Due to bleeding and necrosis, the tips and tails of some ears turn from red to purple or even blue-black, gradually drying up, and are often bitten by other pigs. Acute swine fever pigs, mostly die 10-20 days after infection. A few hours before death, the body temperature dropped below normal.

Subacute forms of swine fever caused by infection with less virulent strains of swine fever virus have symptoms similar to those of acute but are milder and die within 30 days. People who die for more than 30 days are called chronic swine fever. The clinical symptoms of the latter two types are atypical.

According to the clinical symptoms and blood phase changes, the course of subacute and chronic swine fever was divided into three stages: the first stage of the sick pigs showed anorexia, depression, increased body temperature, and leukopenia. After a few weeks, there is a marked improvement in appetite and appearance, the body temperature drops to normal body temperature or slightly higher, and the white blood cells are still reduced, and this improvement in clinical symptoms is characteristic of the second stage.

In the third stage, the sick pigs re-anorexia, depression, and increased body temperature, which continued until death. Or the appetite, spirit, and body temperature return to normal again and become a "zombie pig" or a lifelong poisonous pig. These pigs were severely stunted, with lesions,** and often hunched backs.

Pigs with chronic swine fever can survive for more than 100 days. Depending on the gestation stage and the virulence of the strain, congenital infection can cause miscarriage, mummified fetuses, stillbirths, weak litters and tremor piglets, and newborn piglets that die or are born in piglets that appear healthy but are in fact persistently infected.
