Runting stunting syndrome (RSS) is a multifactorial disease with many names and faces that had caused considerable economic losses to poultry through reduced uniformity, reduced livability, decreased body weights, elevated feed conversions, and many secondary diseases. The aim of the current study was to evaluate the effect of stunting syndrome on histopathology in chicks ( ) of different ages collected from nine different farms. Grouping was done on the basis of age (G1 = 1–10 days, G2 = 11–20 days, G3 = 21–30 days, and G4 = 31–40 days) including both stunted and normal chicks. Histopathological findings were the intestinal lesions (29%), including degeneration of villi, crypts, epithelial cells and lamina propria. Pancreatic histopathological lesions (16.65%) included the fibrosis, vacuolation, and degeneration of acinar cells. Degeneration of follicles and epithelial cells, of bursa of fabricius (43%) and dilation of glandular cells of proventriculus including lymphocytes infiltration (5.6%) were other histopathological findings. All these changes may interfere with normal digestive processes and normal body functioning resulting in poor weight gain and retarded growth or stunting of chicks.
