Recently, due to the large number of ternary pigs turning, the proportion of first-born pigs is relatively high, and the problem of piglet diarrhea has become more serious. Most pig farms are unable to determine the disease in time, which delays the time for better prevention and control, thereby increasing pig injuries and deaths. , Causing huge losses to the pig farm. We have sorted out the common types of diarrhea and prevention and control in the delivery room of pig farms, hoping to help the first-line production.

Diarrhea in piglets less than 7 days old

Piglet red diarrhea: caused by Clostridium weichii type C and spread through the digestive tract. Piglets from 1 to 3 days old are often infected by sucking on contaminated nipples or swallowing contaminants. Acute onset, often acute death, clinically seen in reddish-brown bloody stool, fishy smell, high mortality.

Piglet yellow scour: It can occur all year round due to E. coli, and it is more common in piglets a few hours after birth to 7 days old. Clinical features are more common in sick piglets with discharge of yellow mucous feces and acute dehydration, weight loss, high fatality rate, low body temperature and good spirits, but a large number of deaths may occur after the disease worsens.

Diarrhea in piglets 7-21 days old

Coccidial diarrhea: Piglets usually have diarrhea around 10 days of age, and their stools are mostly white, gray or yellow paste, occasionally watery diarrhea, foul smell, high morbidity but low mortality, diarrhea piglets gradually lose weight. Growth stagnation, uneven growth and development of piglets in the same litter, and air bubbles in thin manure.

Nutritional diarrhea: Often due to sows eating or undernourishment, the milk quality declines after a week, and the digestive function of the piglets is not sound, which leads to diarrhea. The age of onset is mostly concentrated in the age of 10-15 days and within 1 week after weaning. In clinics, piglets are often in low spirits, dull coat, yellow and shiny mushy stool, and occasionally yellow watery stool, which can lead to death of piglets due to dehydration.

Pseudorabies-induced diarrhea: It is often caused by early pseudorabies infection. It is common in piglets at 7-15 days. Clinical manifestations are neurological symptoms, yellow and thin watery stools, and may be accompanied by vomiting. The incidence is 20%-40 %, the fatality rate is 10%~20%.

Piglet white scour: It is caused by E. coli and can occur throughout the year. The sick piglet discharges gray and mushy dung with a fishy smell and pollutes the anus and hind limbs. The sick pig eats little or no food, dehydrates, gradually loses weight, and died of exhaustion. , The body temperature is not high.

Diarrhea from 21 days old to before and after weaning

Spirochete: It is caused by Leptospira porcine, often suddenly onset, the body temperature rises to 40-41℃, the sick pig is mentally depressed, anorexia, diarrhea, dry skin and mucosal jaundice, neurological weakness and tremor on the hind limbs; hemoglobin in some cases Urine, urine color is like strong tea; feces are green with foul smell, bloody feces can be seen for a long course of disease, and the mortality rate can reach more than 50%.

Rotavirus: Caused by rotavirus, it is more common in the cold winter and spring. The main clinical manifestations are mental fatigue, no or little food, often vomiting, watery or mushy, yellow-white or dark black diarrhea, rapid Dehydration etc. The big difference from transmissible gastroenteritis is that adult pigs are not susceptible.

Pigs of any age are susceptible to diarrhea

Transmissible gastroenteritis and epidemic diarrhea: caused by the gastroenteritis virus and epidemic diarrhea virus of the Coronavirus family. Vomiting first appeared in the clinic, followed by acute watery diarrhea. The stool was mostly yellow-green or gray-brown, accompanied by There are flocculent curds, the piglets are rapidly dehydrated, and the mortality rate is high. Even the undead piglets become stiff pigs due to stagnant growth. Pigs at any stage are susceptible, often showing whole herd outbreaks with heavy casualties.

Recommendations for preventing and controlling diarrhea

1. For bacterial diarrhea, neomycin, gentamicin, florfenicol, colistin, cephalosporin sodium, quinolones, etc. are often used to have a certain effect. And it is necessary to control the breeding environment and achieve the same treatment of mother and child in order to achieve good results.

2. Nutritional diarrhea should improve sow nutrition and balanced diet, and add microecological agents and intestinal regulators to the feed or drinking water of sows and piglets.

3. Stressful diarrhea must first eliminate the cause and reduce the stress of the pig herd. Use multi-dimensional drinking water in advance before changing herd or refueling, and increasing the temperature and dryness of the pig house will help the recovery of stress diarrhea.

4. For viral diarrhea, we must first choose a safe and efficient vaccine against epidemic strains of diarrhea, and choose a live plus kill immunization program to ensure that the whole herd general immunization and prenatal fetal immunization of sows are carried out during the high-incidence season each year. In addition, they must cooperate with sound biological safety. System and good feeding management level can play a better prevention and control effect.
