Case Study 1

Problem:
• There has been the incidence of 7-14 day piglet diarrhea in the farrowing barn for 2-3 consecutive months.

Farm analysis:
• Farrowing house is lifted-over with slatted floor and there are fans over the pen.
• There is no permanent brooding box, but sack.
• The downtime for cleaning and disinfecting between flock is 10 days.
• Feces collection in the house has been done 3-4 times per day.
• The water used is the ground-water treated by chlorine.
• There are only individual sows with MMA syndrome. These sows are treated with amoxicillin and antipyretics for 3 consecutive days.
• The piglets with diarrhea condition are emaciated, long-haired with creamy-yellowish feces. Eighty percentage of feces is without froth while the rest is with froth.
• The sick piglets are treated with gentamicin injection.

Suspected problems:
• The tentative causes of diarrhea are E. coli and Isospora suis.

Expected predisposing causes:
• Wind-chill effect from the fans over the pen and poor brooding management.
• Poor mouth-pumping of anticoccidial administration according to the eructation of anticoccidial is found.

Problem solving:
• Keep the piglets warm in brooding management and beware of wind-chill directly contacting the piglets.
• Individually and carefully pump the anticoccidial to the piglet mouth and wait for the piglet to swallow the drug before letting go in order to avoid the eructation.

Problem following:
• There still are piglets with diarrhea condition.

Additional investigation:
• The amount of chlorine used in the water treatment.
• The sensitivity test of E.coli to antibiotics.

Results:
• The chlorine injector has not been used for a month according to the outlet obstruction.
• The chlorine is found to be suspending in the chlorine tank.
• The sensitivity test of E.coli cultured from the feces is found to be sensitive to gentamicin and colistin.

Conclusion:
• There are many factors causing diarrhea in piglets.
• The routine management should be monitored to avoid the consequences of poor management.
• The treatment by gentamicin injection is still effective.
• The preventive measure by adding colistin in feed is another alternative.
