Diarrhoea sometimes becomes a very serious affection in cattle. It may come from chronic indigestion or it may be due to an overfeed of grain; it also frequently happens from eating some irritating or poisonous substance.
Symptoms. - The symptoms are very apparent. The discharge from the bowels is very profuse; it is often very dark in color and has a fetid odor. In the beginning there is generally great thirst, but no appetite for food. If the disease continues for some time the animal becomes so prostrated that it cannot rise to its feet, and the discharge becomes thin and watery.
Treatment. - It will do no good to give astringents to check the discharge until the bowels have been cleansed of all irritating substance; hence, one and a half pints of raw oil and two ounces of laudanum should be given at once, and if there is much pain, an ounce of laudanum and four ounces of raw oil may be given every two hours until the pain ceases. An ounce of hyposulphite of soda should be given every three or four hours, either in a quart of water or slippery elm tea. After the oil has operated, take four heaping tablespoonfulls of wheat flour and make into thin gruel by boiling over a slow fire; give this at one dose and repeat every six hours until the bowels begin to check. Feed on light, nourishing diet for a few days until the stomach has had time to recover from the shock.
