True or False: Formula feedings should be discontinued in the case of diarrhea in young mammals.

• A. True
• B. False
• C. Not at all related
• D. Only when the animal is very young

Answer: (A)

When young mammals have diarrhea, the priority is to correct dehydration and electrolyte losses and to rest and protect a gut that’s not absorbing nutrients well. Fluid and electrolyte balance can deteriorate quickly with diarrhea, so continuing formula at this moment can worsen dehydration and may not improve or could even worsen stool output. By temporarily discontinuing formula, you reduce ongoing osmotic load on the gut and give time to rehydrate using appropriate fluids (electrolyte solutions or IV fluids) and then reintroduce feeds gradually once hydration is stable. After rehydration, resume feeding carefully with small, easily digestible amounts and monitor for tolerance and stool changes.
