The most common cause of death among small children at the turn of the twentieth century used to be dehydration caused by diarrhea. Professor Ernst Moro, a pediatrician, found that he could lower the death rate dramatically about 1908 by feeding the children a simple carrot soup and this recipe became the standard regimen until the development of antibiotics at about 1940.
By far the major cause of diarrhea is an infection by micro-organisms that multiply in the intestines and excrete various toxins. This scenario causes an increase in intestinal motility and massive excretion of semi-digested food and fluids.
Dr. Moro had no idea why this simple soup was so beneficial. It took modern science to uncover the secret: Various pathogenic micro-organisms attach to receptors on the intestinal wall.
The preparation of the carrot soup splits the sugars present in the carrots into very small oligosaccharides which in turn are very similar to the intestinal receptors.
The pathogens attach to these oligosaccharides and are safely excreted before they can cause any problems.
Although no longer used against diarrhea in children this soup finds application against diarrhea in various livestock and chicken.
It may be beneficial to prevent "young bird sickness" and even treat it in its very early stages. It may also be used again against infections by antibiotic resistant micro-organisms and is still used with raising pigs and chicken thereby saving the use of antibiotics.
Recipe for 40 pigeons:
1 kg diced carrots
2 l water
Let the above simmer for at least 1 hour (this time is important), add 1 tsp. salt and divide the liquid into 3 equal portions. Use one portion (ca. 700 ml) in the drinker (mixed with 1900 ml water) for 3 consecutive days.
Should the birds already be sick it may be best to feed just some pelleted feed for a day or two instead of grain that may be too hard to digest or feed germinated grain that is not moldy. I would also purée the soup undiluted and feed 15 ml of it at a time
with a syringe instead of using only the water.
