Rumen acidosis complex is a common disease of feedlot lambs. It is most likely to be seen when the lambs are being pushed on high quality feeds. The clinical signs are an inability to rise, grunting, abdominal distention, diarrhea and sudden death. Treatment involves oral antacids or baking soda, antibiotics, IV fluids and intensive care. It is possible to perform surgery on the rumen to remove the excess undigested grain. Prevention is rooted in good management. This is not as much of a problem in goats are they are not normally raised on a feedlot.
