Vomiting and watery diarrhea, digestive diseases with a very similar to TGE , mortality less than 2 weeks old piglets is lower than the incidence of TGE and the adult morbidity appear higher. Year-round onset and propagation velocity is gentle compared to TGE. Mortality with a mixed infection of E. coli increased.
1. Agent
Coronaviridae Coronavirus(Porcine epidemic diarrhea virus, PEDV)
2. Epidemiology
And it occurs mainly in certain countries around the Southeast.
3. Clinical Signs
Clinical symptoms are similar to TGE and diarrhea, loss of appetite, cause nausea.
. Suckling piglet: Symptoms of severe dehydration cases of newborn piglets of less than one week old young age is the more severe mortality while a 3 to 4 day diarrhea.
. Weaner : after the pig is watery diarrhea lasting 4-6 days and then create a transition point but recovered most severe weight loss.
. Adult pigs : show symptoms such as lack of appetite, most vomiting, loss of stamina, and recovery. If the infection at the end of fattening as acute diarrhea sudden lapse in the early even if there is necrosis of the abdominal muscles is a common autopsy findings are observed.
. The incubation period : 26-36 hours in the newborn piglets, finisher have a long incubation period is two days, but longer during natural infection.
. Mortality: within 1 week, depending on the different days of age in average amounts to 50% and 90% severe. Finishing is one week after the recovery is as low as 1-3%.
4. Prevention
1) Strategy
Prevent secondary bacterial infection, and as symptomatic therapy to relieve dehydration due to diarrhea and vomiting or give supplies enough glucose and electrolytes to maintain the thermal insulation to reduce the mortality of piglets.
In the case of pig farms illness occurred after a thorough disinfection of the pregnant sows to date to move closer to the delivery room and the other special disinfection managed to block the spread of pathogens.
Until at least three weeks after suckling piglets should prevent infection with the virus.
Pigs and pig farms to buy only reliable diarrheal disease could not occur at the time of purchase.
Pigs and feed transport vehicles, transit traders, other pig farms, etc. and control the entry of outsiders, unavoidable cases, ever accessible and disinfection measures.
There is excreted by an infected pig poop contains a large amount of pathogen propagation is an important factor because it groups dedicated to the thorough disinfection and sanitation of around pig farms.
2) Vaccination
PED live vaccine for primary immunization at 4-5 weeks before in the pregnant sow and re-vaccination 2-3 weeks before the birth to prevent diarrhea in piglets through maternal antibodies implement.
