One-day-old poults were placed on littler on which poults had previously developed diarrhea, increased mortality, and stunting. Small intestines, pancreas, and liver were evaluated histologically. Morphometric evaluations were conducted to determine villous length and crypt depth. Poults were evaluated for malabsorption utilizing D-xylose and lipid absorption tests. Compared with controls, the gastrointestinal tract of affected birds was grossly distended, was fluid-filled, and had thin, flaccid walls on days 5 and 8. Ceca were distended with brown watery fluid and gas on days 5, 8, and 12. No histologic lesions were present in the liver, pancreas, or pancreatic ducts, and only mild inflammatory changes were present in the small intestine. Villous atrophy and crypt hypertrophy were present in the small intestine on days 5, 8, 12, 16, and 21. Morphometry revealed significant decreases in villous lengths and increases in crypt depth throughout the trial. D-xylose and lipid absorption were significantly decreased on days 8 and 11. Intestinal epithelial damage by infectious agents with subsequent villous atrophy is postulated to have produced malabsorptive diarrhea.
