When it comes to viral diarrhea, many pig breeding people have a hint of fear. As long as the pigs have been raised for a few years, who hasn’t encountered diarrhea?In various causes of diarrhea, the most damage caused by viral diarrhea is the largest, the water sample is diarrhea, the dehydration is severe, and the mortality rate is high.In the classification of viral diarrhea, infectious gastroenteritis and epidemic diarrhea are definitely the number one natural enemy of pigs.Today, we will unveil the true veils of these two viral diarrhea, so that the pig farmers can prevent it correctly, and give you a complete treatment plan for many years of clinical trial effects.
Infectious gastroenteritis (TGE) is a kind of acute digestive tract infectious disease caused by pig infectious gastroenteritis virus, mainly in the cold autumn and winter seasons.Pigs of different ages and varieties are susceptible to infection. The mortality rate is very high after infection within 15 days.As the age increases, the incidence gradually decreases, the symptoms gradually decrease, and the fat pigs are benign.Poisonous pigs and rehabilitation are the main source of infection. Healthy pigs are infected by digestive or respiratory tracts through the feed and air contaminated by viruses. Poor viruses with poor ventilation, high humidity, and density are easier to spread.
Symptoms: After being infected by the virus, the incubation period of the piglet is about 16 hours and the fattening pigs are 2-3 days.The piglets suddenly developed, and then a sharp water -like diarrhea occurred. Most of the feces were gray -white or yellow -green, which contained unlute milk clots or feed.Some sick pig temperatures rose first, and the body temperature decreased after diarrhea, rapid dehydration, and rapid weight loss.Severe thirst, loss of appetite or waste.The smaller the younger pig, the shorter the disease, and the higher the mortality rate.During the 15th, piglets were not infected with timely mortality rates. Pigs with healed diseases were damaged due to intestinal mucosa, growing slowly, and even stiff pigs.
The symptoms of fattening pigs and adult pigs are relatively mild, the amount of feeding may be reduced, diarrhea and vomiting, and the weight is rapidly alleviated.Sow anorexia and decreased lactation.Generally, 3-7 days will recover by themselves, and they rarely die.
Among the symptoms of coding, the main lesions are in the stomach and small intestine, the stomach contains milk condensate or feed particles, and the mucosa of the stomach is slightly bleeding.The small intestine is filled with yellow -green and gray -white sticky materials, containing undigested milk clocks or feed. The intestinal wall becomes thinner and elastic, and the intestinal tube is expanded and transparent.
Pig flow diarrhea (PED) is a highly contagious intestinal disease caused by pig infection with epidemic diarrhea virus. The main characteristics are vomiting, diarrhea, and dehydration.This virus will only be infected with pigs, and pigs at all stages are susceptible to infection.The propagation method is basically the same as the infectious gastroenteritis, mainly through digestive tract transmission.From September from September to April of the following year, there are outbreaks of the disease in various regions, and the infection is quickly
Symptoms: Once the breastfeeding piglet is infected, the symptoms are very obvious, and symptoms such as vomiting, diarrhea, dehydration, and stiffness of exercise are manifested.A few sick pigs increased by 1-2 ° C. At the beginning of the diarrhea, yellow viscous feces were rowed, and then it became water-like diarrhea.The severity of clinical symptoms is different with age. The smaller the age, the more severe the symptoms. The piglets often die after 2-4 days of diarrhea, and the mortality rate is as high as 50%.Broken piglets and fertilizer pigs have mild symptoms. They have depression and poor appetite. They last for about a week and gradually return to normal.Adult pigs are only manifested as symptoms such as mental deficiency, anorexia, and vomiting.
After the dissection, the main lesions are in the small intestine.The small intestine expands, full of light yellow liquid, the intestinal wall becomes thinner, and individual intestinal mucosa has bleeding points.Small velvet firing becomes shorter, and the severe pills shrink and even disappear.The stomach is often empty, and other organs do not have substantial lesions.
These two diseases are difficult to distinguish from the aspects of symptoms, onset time, and the size of the pigs. It is too similar. However, after years of experience, I summarize the following points that can identify these two diarrhea:
The color of the feces: infectious gastrointestinal inflammatory feces are mostly yellow -green or milky white, while the stools of popular diarrhea are mostly gray -black;
How much vomiting: there are more vomiting symptoms after infection gastroenteritis, and the main symptoms of epidemic diarrhea are water -like diarrhea, less vomiting symptoms;
Stroke of feces: Infectious gastrointestinal feces contain unbounded milk condensate or feed particles, and epidemic diarrhea is completely water -like diarrhea;
Diseases: The main lesions of infectious gastroenteritis are gastric and small intestines, with content in the stomach, and gastric mucosa have slight bleeding; while the stomach of epidemic diarrhea is basically empty, the stomach has no lesion;
Difficulty of treatment: Infectious gastroenteritis is better than epidemic diarrhea
The symptoms and preventive methods of these two diseases are basically the same, so here is the case.
Vaccine immunity: Vaccine immunity is the simplest, convenient and effective prevention method.Because the disease is most serious in the delivery room, the vaccine immunity is to protect piglets.Pregnant sowing 2-3 weeks before gastrointestinal gastrointestinalitis, epidemic diarrhea, or infectious gastroenteritis, epidemic diarrhea, and rotary virus triple seedlings, each sow is 5 copies; then the piglets were bornAt 5-7 days, each piglet was inoculated.
Breeding management: Newborn piglets should eat colostrum as soon as possible, because colostrum contains a certain amount of protective antibodies, and piglets get certain resistance after eating colostrum.The pig house should do a good job of heat preservation. Coldness is an important factor that causes viral diarrhea.Pig and utensils should be disinfected frequently, reducing the content of pathogenic microorganisms in the environment, and reducing opportunities for pathogenesis.
Drug prevention: On the third day after the birth of piglets, the first needle of three needles for piglets was used to make piglets with long -effect earthycin or cephalosporin suspension. At the age of 7 days, the second needle can effectively reduce the occurrence of various diseases.
Pig infectious gastrointestinalitis and epidemic diarrhea are viral diarrhea, and the symptoms are very similar. Therefore, the treatment methods are basically the same.However, only one or two medicines are often treated with good results. There must be a overall solution. The following is the method of practical operation of the author:
Drug selection: Drugs are mainly divided into two ideas, one is antiviral products, such as interferon and immunoglobulin; the other is effective antidiarrheal drugs, such as sulfate small alkali, Bonnoshaxing, etc.The older drugs such as penicillin and chaincin are basically useless to viral diarrhea.These two types of drugs are injected and edged to play an effect of antiviral and antidiarrheal convergence.
Auxiliary applications of probiotics: Due to the restrictions of antibiotics in recent years, the development of probiotics has developed rapidly, and many products that can have practical effects have been developed.For diarrhea, probiotics such as Berrye and Bacillus of Berbalus, Bacterium Bacteria, etc. can be used to take orally for piglets to regulate the intestinal flora, thereby promoting anti -diarrhea and the recovery of the intestinal tract.
Moisturizing: Because viral diarrhea often causes serious dehydration of piglets, this is the direct cause of the death of piglets, so hydration is essential.According to experience, small pigs within 10 days of age are drew 5 ml of glucose water and 5 ml of physiological saline each time; small pigs for 10-30 days, 10-15 ml of physiological saline and glucose water each time.Repeat 3-5 times a day to ensure sufficient water and physical fitness of the piglets, and recovery is fast.
Heating: No matter what kind of diarrhea occurs, the temperature of the pig house is increased to 1-2 degrees higher than the normal level, so that the piglets feel comfortable and have great benefits to the recovery of diarrhea.
Summary: As the old pig raising people say, raising pigs is intestinal.Little pigs are nourishing the intestines. To prevent diarrhea, diarrhea is the enemy of piglets; the big pig nourishes the intestinal tract. In order to improve the meat ratio, it can better use the feed.This set of diarrhea plans do have very good effects in practical applications. It has helped many pig friends to solve diarrhea problems. Share it with friends to try it.
